e.

The law stipulates stipulates that that machine machine tools tools must must be grounde grounded d (by Class-D Class-D grounding grounding work). work). When requesting an electrician for construction work of electric facilities, instruct the electrician to perform Class-D grounding work based on the technical standard for electric facilities. If the machine is not connected with a ground, insulation failure may cause the leaked current to flow into a human body, resulting in serious injury involving death.

f.

Connect Connect the machine machine to the ground ground using an individ individual ual cable. cable. If there there is no choice choice but to to use a common grounding cable, avoid shared use with the equipment that generates a large amount of noise (such as an electric welder or an electric discharge machine).

Before Turning on the Power • Make sure that the doors to the operation panel and the electric control cabinet are closed. • Make sure that there are no obstacles around the machine. • Turn on the main power disconnect switch before turning on the CONTROL on the operation panel.

3.

Chuck Precautions • Always close the front shield before starting the spindle or cutting operations. • Always observe the spindle speed maximums for the installed chuck. Never run the spindle exceeding the maximum allowable chuck speed.

• If a chuck or fixture is unique to your application, check the maximum allowable spindle speed and stay within the limit. Also, take note of the workpiece gripping force and balance.

• The maximum spindle speed can be limited by inputting a G50 command with the spindle speed. The G50 command helps to ensure safety in operation.

4993-E P-(iii) SAFETY PRECAUTIONS

• If the spindle must be rotated close to the maximum allowable chuck speed, observe the following points: The maximum allowable spindle speed and application pressure are indicated on the name plate on the front shield and on the chuck body. The allowable maximum speed and the applicable pressure ensure a chucking force that is more than one-third over the original chuck gripping force with the standard soft-top jaw set in line with the periphery of the chuck body. body. a.

Make Make sure that that the the workpi workpiece ece clam clamped ped in the the chuck chuck is is balanc balanced. ed.

b.

Apply the the allowabl allowable e maximum maximum amount amount of pressure pressure to grip grip the the workpiece workpiece because because centrifucentrifugal force reduces the chuck gripping force.

• If special jaws (larger than standard soft-top jaws) are used, observe the following points: a.

Lower the spindle spindle speed speed because because centrifugal centrifugal force and and lower lower efficien efficiency cy reduce reduce the chuck gripping force.

b.

If the jaw jaw tightening tightening nut nut (jaw nut) nut) is outside outside of the periphery periphery of of the chuck, chuck, only one tightentightening bolt is holding the jaws in place. This is a potentially dangerous condition. Jaw nuts must always be within the periphery of the chuck.

Site Selection Guidelines In order to ensure high machine accuracy and performance, the following points should be considered with regard to the installation site. (1) Foundation Foundation work is advised advised for sites sites where where the subsoil subsoil is soft, soft, to prevent the the machine from from tilting or sinking after installation. For details regarding foundations, refer to 2. “Foundation Dependant of Ground Condition” in this section. (2) The installati installation on site should should be as far as possible possible from vibration vibration sources sources such such as roads, stampstamping/press equipment, or planer machine tools. If nearby sources of vibration are unavoidable, prepare dampening pits around foundation to reduce the vibration effects. (3) NC malfunctions malfunctions could could result from the proximity proximity of high-frequ high-frequency ency power generators generators,, electric electric discharge machines, and electric welding machines, or when power is supplied from the same distributor panel as these machines. For wiring details, consult our service engineer dispatched to assist with installation. (4) The ideal ideal operating operating environme environment nt calls for for an ambient ambient temperatur temperature e of 20°C, with humidity between 40 and 75%. (5) Keeping the ambient ambient temperature temperature at a constant constant level level is an essential essential factor for accurate accurate machinmachining. (6) In order to maintain maintain static static machine accuracy accuracy within within guaranteed guaranteed values, the machine machine installatio installation n site should be located so that it is unaffected by air curr ents within the factory. Although air-conditioning is not required, the optimal ambient temperature range it 17°C to 25°C (7) To maintain maintain static machine machine accuracy accuracy at levels even higher than the standard standard guaranteed guaranteed values: values: a) Keep the ambient ambient temperature temperature variance variance for 24 hours hours (1 day) day) within within ±2°C. b) Ambient temperatu temperature re variances variances from floor floor level to a height height of about 5 meters meters should should be held within 1°C.

Care Care in Mach Machin ine e Tra Trans nspo port rtat atio ion n This machine integrates hydraulic unit, control cabinet, and NC unit into one construction instead of having them as separate units, and so the machine can be easily moved or transported. There are two different methods for moving the entire machine to any desired location; by an overhead crane, using lifting hooks supplied together with the machine and by rolls over which the machine is pushed by manual labor.

LE11137R0500400020001

Procedure :

1-

Locate the upper saddle to the left-hand end of travel (negative stroke limit position of Zaxis). For two-turret models, locate the lower turret to the left-hand end of travel (negative stroke limit position of Z-axis). When the machine is equipped with the tailstock, position the tailstock at the far right end position. Turn off power supply to the machine.

2-

Remove the headstock LH side cover (A) and the headstock front cover (C), and fix the lifting hooks at three positions. At the tailstock side, the chip falling gap on the bed is used for lifting the machine.

3-

Move the front sliding cover (chip guard) (D) to the position where cables will not interfere with it when they are hooked around the lifting hooks (E). Place protective pad between the headstock and the cable hooked around the hook at the headstock front.

Now the machine is ready to be lifted.


Precautions for Lifting

WARNING • The cables should have a nominal diameter of 20 mm (0.79 in.) or larger. • Change an angle formed by each cable line so that the cables will not contact the finished surfaces of the machine. (Do not tilt any wire rope exceeding 40 degrees away from the vertical direction.)

• Check for balance and be very careful when lifting the machine. • Use extra care to lower the machine gently onto the floor; NEVER APPLY SHOCKS TO THE MACHINE WHEN PLACING IT ON THE FLOOR.

Foundation Requirements

2-1. 2-1.

Prec Precau auti tion ons s for for Foun Founda dati tion on Wor ork k SAFETY INSTRUCTIONS With a solid ground, a concrete floor about 200 mm (7.87 in.) thick and no gaps between ground and floor, foundation work or anchoring is not required. The structural rigidity of the machine permits normal machining. For long-maintained accuracy and where sub-soil or ground under the floor is not strong enough, a new concrete foundation should be set up in accordance with the Foundation Plan in this section.

• Foundation requirements vary depending on the characteristics of the sub-soil. Under any soil conditions, it is important that sub-soil should be well compacted to keep the foundation from unsettling once the machine has been installed.

• Where sub-soil is too soft, it is necessary to drive concrete piles into the sub-soil. • The Foundation Plan attached to this Manual is prepared for laying a typical concrete foundation specifically for the machine. The concrete thickness or depth should be determined in terms of the ground condition in each case.

• The digital AC voltmeter makes a slow response, and therefore the measured value tends to be a little lower than the actual value. It is recommended to use the analogue AC voltmeter.

• Shorter deceleration time makes the measurement difficult. Measure the voltage while decelerating the motor from the possible highest speed.

• Obtain the instantaneous voltage regulation after ensuring that the alarm “Voltage regulation too large” is not activated. This is because the alarm causes the motor control unit to restrict the motor output.

Setti tting Zero Offsets What is Zero Offset? The common coordinate position from which a complete program is made for a particular component is termed “zero point or program zero”. The program zero is located at the fixed position (center of the spindle) on the X-axis. However, the program zero on the Z-axis will vary depending on the setup (incl. chuck, jaws, etc.) as indicated with A’ and B’ in the figure below.

Machine zero

Reference point of machining on Z-axis (program zero) LE11137R0500500040001

The operator can establish the reference point for machining (zero point of a program) by entering X0 and Z0 through the keyboard dimensioned from the fixed zero point of the machine. X0, Z0 is called Zero Offset Values.

Reference point for machining (program zero)

Z0 Zero offset

Z Actual position

Current position ZA on machine coordinate system

Current position ZA on machine coordinate system

The NC machining program needs distance Z as absolute position of the tool at A.

The control always performs calculation "ZA-Z0" to obtain the actual position of the tool.

The operator can set the reference point point of machining(machining origin) at any desired point by entering zero offset value Z0. LE11137R0500500050001


Setting Zero Offset Values There are three possible cases for entering zero offset values:

• Where zero offset values are unknown, as in cutting the first workpiece for instance. • Where zero offset values are known, as in cutting workpieces of repetitive lots. • Where the stored offset values are modified. Explanation for each case is provided in this paragraph with the following example. Machine zero

This completes setting the zero offset value.


CAUTION • Never move the turret in the Z-axis direction until zero offset setting is completed. Keep locating the turret in the position set in the step

“1-” .

• For the X-axis, the reference point does not change even when the checking method or setup changes. Therefore, there is no need to carry out zero offset each time the set up changes.

• Use a tool with offset values of X = 0, Z = 0, where practicable, for zero offset setting. If the tool offset values are not zero, the zero offset setting procedure will differ from the procedure indicated above. The numeral data entered through the keyboard in the above step “8-” is the sum of “measured value” and “tool offset value”. Example: A tool with a tool offset value of Z = -0.500 is used. The zero offset value is calculated as 100.000 + (-0.500) = 99.500 Setting value Tool offset value Measured value Cutting tool with tool offset Z=0

Hydraulic Power Unit

LE11137R0500500100001


Pressure Indication The pressure gauge is used to indicate the different levels of hydraulic pressure directed to individual functional units on the machine. The selector valve is used to switch the pressure gauge line.

LE11137R0500500110001

Procedure :

1-

Match the red paint mark on the knob of the valve with the identification line as shown.

2-

Push the valve in.

3-

The pressure gauge indicates the setting of oil pressure in the selected pressure line.

To check oil pressure to the disc-type spindle brake, shut off the incoming power supply by turning off the main switch, and then turn on the main switch again. With only the main switch turned on, proceed with the reading of the pressure gauge as noted above. These steps are required since the pressure gauge can only indicate the working pressure in the selected line for a very short period of time. The pressure settings are as follows: Hydraulic power chuck

See Item 2-3.

Turret index and clamp

3.4 MPa {35 kgf/cm 2 (498 psi)} maximum

Hydraulic spindle brake

1.5 MPa {15 kgf/cm 2 (213 psi)}


Adjustment of Hydraulic Pressure The following outlines the methods of setting individual functional units for operating pressure. Since the pressure lines for the turret(s) have been adjusted at our factory before shipment, they will not require readjustments, during the initial installation and subsequent normal service of the machine. When readjustment is to be made by your plant personnel, extreme caution must be taken in accordance with the instructions given here to avert any mechanical trouble in the drive lines.

• Hydraulic pressure for power chuck. Refer to Item 2-3. • Turret pressure adjustment (Adjustment is not usually required.)

Pressure decrease

Pressure increase

System Pressure Adjusting Valve LE11137R0500500120001

Use the system pressure adjusting valve to adjust the turret pressure since the turret pressure is the same as the system pressure.

Master jaw Chuck body Connecting rod

Nut

Draw screw A Pilot bushing

Draw tube

CHUCK operating pedal

Top jaw Wedge plunger Mounting bolt B LE11137R0500500170001

Installation of Hydraulic Chuck Procedure :

1-

Press the CONTROL ON pushbutton switch on the operation panel and step on the CHUCK operation foot panel. This causes the connecting rod in the spindle bore to move forward.

2-

Fasten the connecting rod to the draw screws A. * Use the Allen wrench furnished with the machine.

3-

Secure the chuck body onto the spindle end, using mounting bolts B.

4-

Adjust the draw screw A so that the outer ends of the master jaws become flush with the peripheral surface of the chuck body when the top jaws are in the OPEN condition.

The individual chuck jaws can be moved in the “opening” direction as the draw screw A is turned in the counterclockwise direction. Removal of the hydraulic chuck from the spindle is the reverse of installation in steps from “3-” to “2-” .

WARNING When changing parts such as chuck, jaws, or stopper block inside the chip and coolant shield, keep the following in mind:

• Always shut off the source power before changing parts. • Never issue M19 (spindle orientation) or M110 (C-axis joint) command while changing parts.


Adjustment of Oil Pressure for Hydraulic Chuck The gripping pressure of the chuck jaws is dependent upon the working pressure of hydraulic fluid which is determined by the setting of the pressure adjusting valve installed at the hydraulic unit. A clockwise turn of the valve knob decreases the working oil pressure directed into the chuck cylinder and counterclockwise turn increases it. The hydraulic chuck pressure can be adjusted with the pressure adjusting valve of the hydraulic unit. Clockwise turn increases the pressure and counterclockwise turn decreases the pressure. Adjust the pressure to a value under the max working pressure of the chuck.

LE11137R0500500190001

Maximum Permissible Spindle Speeds and Oil Pressure Setting Maximum permissible spindle speed varies depending on types of chuck and cylinder to be used. The allowable chuck rotation speed depends on the chuck and cylinder types. Use the chuck under the specified max rotation speed.

WARNING When using a chuck, follow the instruction on the name plate at the front cover of the machine.


How to set Maximum Spindle Speed The maximum spindle speed to which spindle speed is to be limited due to chuck specifications, influence of centrifugal force on chuck gripping force, imbalance of workpiece, etc. can be set by program. Format: G50

S OOOO

⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅⋅To be specified in a block without other commands

Specify the required maximum spindle speed. LE11137R0500500210001

CAUTION • Whenever the machine has to be operated at a speed as high as its maximum available chuck RPM, avoid any work running out of balance, and be sure to increase the hydraulic working pressure to the maximum allowable pressure limit, because the actual gripping force might be reduced with the increase in the spindle speed due to centrifugal force acting on the chuck jaws.

• The maximum chuck RPM refers to the speed at which the chuck can be turned, with its gripping force maintained within more than one-third of its rating, while the outer ends of the individual top jaws are positioned evenly with the peripheral surface of the body. Notice that other limiting factors are considered; factors which may be associated with the overheating of the main drive motor due to frequent starts and stops.

• When soft top jaws larger than standard ones provided with the machine are prepared by the customer and used with the chuck, keep in mind that developing centrifugal force and decreasing efficiency may reduce the actual gripping force. Be sure to reduce the spindle speed accordingly.

• Where jaw nuts shown below go beyond the peripheral surface of the body, only one bolt secures the corresponding jaw and a very dangerous condition is created. Always locate the jaw nuts within the periphery of the body as shown below. It is a good and safe practice to use soft top jaws that are made to fit the actual work configuration. Jaw nut

Change of Chuck Gripping Direction - ID/OD Gripping Gripping direction of the power chuck - ID gripping and OD gripping - can be changed by pressing the flat key on the operation panel. The change of gripping direction may be made only while the spindle stops.

Greasing

CAUTION The chuck has grease nipples either on the chuck front face or on its periphery. Apply grease (Molykote EP grease) to the nipples every day. Since chips and foreign matter accumulate on the jaw moving surfaces on the chuck, clean them every day and lubricate them with the hydraulic oil (HM32, MAS).

Installing Chuck • Accuracy of adaptor installation section has direct influence to the workpiece chucking accuracy. Therefore, machine the adaptor very carefully. Required accuracy is within 0.005 mm (0.00020 in.) for run-out on circumference, face run-out, and flatness.

• Any damages such as score or foreign matter on fitting parts and installation surfaces will deteriorate chuck installation accuracy. Install the chuck only after cleaning both the chuck and the adaptor. After the installation of the chuck, measure run-out of the chuck body circumference and face. Run-out must be within 0.020 mm (0.00079 in.).


• Insert the chuck onto the spindle with the chuck drive pin hole aligned with the spindle pin. Tighten the chuck clamping bolts gradually and uniformly. uniformly. After the installation, the chuck fits on the spindle end face in the following manner as illustrated below.

• To clamp a workpiece, use only the handle supplied with the chuck. If a workpiece is clamped forcibly by inserting a pipe into the handle hole, chucked part will be distorted causing shorter life and deteriorated accuracy. If higher clamping force is required for your turning operation, use a larger chuck.

• Never tap a workpiece held in the chuck. • Select the chuck size meeting the intended machining operation.

CAUTION 1) If an excessively excessively long workpiece workpiece is held held by chucking chucking on one side, the workpiece workpiece may sway and damage the machine internal parts. 2) To hold a long workpiece, avoid avoid one-side chucking chucking and use a tailstock tailstock or work rests to securely support the workpiece free end. 3) The allowable allowable work length varies varies with the cutting conditions conditions or workpiece workpiece rigidity. rigidity. As a criterion, if the length “L” in the figure below is longer than the value calculated by the formula below, use a tailstock. L = L1 + (L1 X 3.5)

SECT SECTIO ION N4

INSP INSPEC ECTI TION ON/M /MAI AINT NTEN ENAN ANCE CE (FOR (FOR TROU TROU-BLE-FREE OPERATION) OPERATION)

Your CNC lathe is a highly efficient production machine calling for a much higher utilization rate than an engine lathe. This section deals with the maintenance requirements which must be met by every user in order to insure excellent, trouble-free performance and prolonged life. It also outlines some basic steps to pinpoint possible causes of trouble, together with troubleshooting hints, if your CNC lathe is found out of order in any way, way, or in need of readjustment or repair. Generally, NC lathes are used at three to four times higher “utilization” rates than manually controlled engine lathes. To insure a maximum productive time with a minimum of downtime, the machine must be periodically inspected and carefully serviced. A periodical inspection schedule is presented below. (1) Daily

• Check the oil level gauges (for hydraulic unit, slideway lubricating oil tank, headstock lubricating oil tank), and oil level and flow seen through the sight glass (on the headstock).

• Check the turret and chuck pressures with the gauges on the hydraulic unit (air pressure for the air chuck).

• Apply grease to chuck (air chuck) jaws. (2) Monthly These three items must be carried out after the first month of operation following initial installation of the machine.

• Check the bedways for level and straightness. • Flush out the hydraulic power unit and change the hydraulic fluid. (3) (3) Ever Every y thre three e week weeks s This item must be carried out after the three months of operation following initial installation of the machine.

• Change the oil in the headstock. • Clean the pulse handle. (4) (4) Ever Every y six six mont months hs

• Change the headstock lubricating oil. • Change hydraulic oil in the hydraulic power unit. In addition to the regular maintenance items given above, there are some maintenance items which should be checked according to the actual condition of the machine, as described in this section.


1.

Lubrication [Supplement] The machine should be completely and correctly lubricated in strict adherence to the directions in the Lubrication Chart in the following page. (1) Always Always Use Use the Speci Specifie fied d Lubricat Lubricating ing Oil. Oil.

• If the oil other than specified is used, the lubrication unit might fail to operate normally. • Lubricating oil used in common with coolant or lubricating oil used in common with hydraulic oil might cause corrosion of lubrication unit or mixing of oils to result in lubrication failure, which, in turn, leads to damages on the slideway surfaces. (2) For Coola Coolant, nt, Use Use the Spec Specifi ified ed Coolan Coolant. t.

• Coolant usually contains chemical additives such as activator. If improper coolant is used, lubricating oil will be affected by chemicals and therefore, use the specified coolant so far as possible.

• If coolant which is not our recommendation is to be used, check to be sure that it will not cause any following problems. Mixing with lubricating oil, possible parting, peel of paint, rusting, and swelling of packings If a problem is found during the use of the coolant, avoid the use of such coolant. (3) Amount of Lubricati Lubricating ng Oil and Its Discharge Discharge Conditio Condition n Must Be Checked Checked Everyday. Everyday.

• Whether or not lubricating oil is properly supplied can be checked by checking oil level in the tank. For normal oil consumption amount, refer to “Slideway Lubrication System”. in this section.

• Prior to shipment of the machine from our plant, the oil and the coolant tanks are flushed out and must therefore be refilled during the initial installation of the machine. Headstock Cooling Oil

• As for service point or amount of lubricating oil of the machine, refer to the Instruction Manual of respective machine models.

• Lubricating oil used in common with coolant or lubricating oil used in common with hydraulic oil might cause corrosion of lubrication unit or turbidness of oils to result in lubrication failure, which, in turn, leads to damages on the slideway surface or ball screw. (We take no responsibility for the troubles caused by using the lubricating oil which is not our recommendation.)

• As for oil replenishment for the optional accessories such as special chucks or chip conveyor, refer to the Special Instruction Manual supplied with individual accessories.

• When slideway lubricating oil mixed with coolant and some trouble appears, contact your local Okuma representatives. They have optional accessories such as oil skimmer.

Adjustment of Turret Index Speed

CAUTION Explained in this section is the procedure to change/adjust the turret index speed for respective types of the turret, V12 and V8. However, if the adjustment is made improperly, a trouble will result in the turret index driving system. Therefore, carefully adjust the turret index speed.

V12 Turret Follow the steps below: Procedure :

1-

Remove the cover

2-

Remove the lock nut of the turret index speed adjusting screw.

3-

Turn the turret index speed adjusting screw so that the turret index speed will be about 12 seconds/rotation. CW turning

-

index speed decreases

CCW turni rning

-

index speed increase eases s

4-

After the adjustment, be sure to secure the lock nut tight.

5-

Mount the cover.

V8 Turret (Two-Turret Model) Follow the same procedure as adjusting V12 turret. Adjust the turret index speed to about 8 seconds/rotation.


How How to remo remove ve cove coverr and and loca locate te flow flow cont contro roll valv valve e

Turre urrett inde index x time time

V12 Upper turret

About 12 seconds/ rotation

V8 Lower turret (two-turret model)

About 8 seconds/ rotation

Fully open the flow control valve for adjusting the turret index speed while the turret is at a still. This is to flow away foreign matter if the valve is clogged. After that close the valve completely. NEVER OPEN THE FLOW CONTROL VALVE WHILE THE TURRET IS ROTATING: IF OPENED, THE TURRET WILL ROTATE AT A HIGH SPEED CONSTITUTING HAZARDS TO BOTH THE OPERATOR AND THE MACHINE. Turn the adjusting screw counterclockwise gradually with keeping the TOOL INDEX button on the operation panel pressed, until the specified turret index speed is obtained. After the adjustment, secure the lock nuts and fix the cover as before. Tool: ool: Wrench Wrench - 16 mm mm (0.63 (0.63 in.) Screw driver
