Machine operation

4.1 Controls Fig.4-1 shows the location and function of controls of the machine.

4.2 Method 4.2.1

Drive system

Different spindle speeds are available by setting spindle speed shifting knob (8) and (10). 24-step clockwise or counter-clockwise spindle speeds are gotten if knob (8) is set to one of its 8 with the same color as that of knob (10). See Table 4-1. When knob (10) is set to the neutral (white) position the spindle will disengage from other driving shafts and stop. Feed motion also stops at the same time but it can be activated by using the increased pitch mechanism. Note: Do not operate any lever while the spindle is rotating.

4.2.2 4.2.2.1

Feed system Setting the pitch and feed: Different pitches and feeds are available by setting Pitch

control knob (6) on headstock, Thread selector (7), Feed control lever (9) and Increased feed knob (11). a¡ ¢Pitch control knob £ ¨ 6£ ©is used to change pitch of threads and helix direction, or to change feeds. Because of a single-direction overrunning clutch fixed in the apron, feed motion is impossible unless knob (6) is set to RIGHT-HAND position Right-hand thread with normal pitch. Feed is available. Left-hand thread with normal pitch. No feed. Right-hand thread with increased pitch. Reduced or increased feed. Left-hand threads with increased pitch. No feed. b¡ ¢ Thread selector (7) is designed to select type of threads and also can be used to change

feeds. t

:

= A:B:C:D = 1:2:4:8

By setting the above levers and knobs accordingly different feeds listed in Table 4-2 are obtained. To ensure good operating of machine setting levers and knobs should be based upon the principle that a higher spindle speed matches a finer feed, and vice versa. The leadscrew can be driven directly by shaft ¢ ñ through change gears in stead of externally engaged gears in feeding case in order to cut threads excluded in Table 4-2. To do so, thread selector (7) must be set to NEUTRAL position and Increased feed knob (11) to ¢ ô position. 4.2.2.2

Carriage operation

a. Feed axis selector and rapid traverse button (21) is used to move the carriage or rapidly traverse it in the direction it is set. To rapidly traverse the button on its head should be pressed and held till the carriage moves to the desired position. b. Half nut lever (18) is used to move the carriage back and forth along the bed when cutting threads. The half nut is closed when lever (8) is turned clockwise and separated when lever (8) is turned counter-clockwise. c. Apron handwheel(13), cross slide handle (14) and compound rest handle (20) are all manual controls. Each of them has a dial on its base to indicate distance moved. 4.2.2.3 For other controls, see the operation diagram. When Operating lever (12) or (19) is put to the upper position, the spindle starts to run forward; when it is put to the lower position the spindle starts to run backward; when it is put to the middle position the spindle stops. Note: Operating lever (12) or (19) can not be set from upper position directly to lower position or vice versa.

Maintenance and care

9.1 Lubrication In order to maintain good operation and reduce wear, all running and sliding parts on the machine must be properly lubricated periodically. So pay special attention to the following points. a) Refill clean oil at regular intervals according to the lubrication chart. b) Each of headstock, apron and feeding case should be filled up to the centered line of their

oil gauges. Take care not to be higher than the upper line of each gauge. Oil will overflow in that case. So it is important to check the levels of oil from time to time and keep them in correct position. c)

Because of serous wear on a new machine first change of oil both in headstock and apron

should occur ten days after using of machine and second change twenty days after, thereafter it is replaced every two or three months in order to keep the headstock and apron clean all the time. After the waste is drained out the headstock and apron must be washed with kerosene. d) The filter in headstock and wool strings on the machine must be cleaned every

month. The dust guards at ends of lower guideways of carriage and at left side of tailstock bottom plate should be cleaned every week and be replaced if worn.

9.2 Operation Pay attention to the following points when operating the machine. a)

After the main motor is started, the spindle is started only when the lube pump is

confirmed in good condition and sufficient oil is confirmed in the headstock. b) Never change speed while the spindle is running at a high speed. Change it only when

the spindle is stopped. Feed rate is changed either when the spindle is stopped or running at a lower speed. c)

Before starting the spindle, make sure that every gear-shifting lever is in a correct

position ensuring good engagement between gears. d) When the brake fails to work repair it immediately. Never use the reversing friction clutch as a brake. e)

When operating any of the Operating levers be sure to place it downward or upward

completely. Un-complete operation is not allowed for decreasing the speed during cutting.

9.3 Maintenance In order to maintain the accuracy and service life of every part on the machine, take note of the following points. a) Check and adjust the tension of V-belts periodically to maintain its service life. b) Clean any dirt or waste coolant deposited between the four-way tool post and its slide to keep repeatability of the slide. c)

If the tailstock is used to support the workpiece for cutting, a Morse Taper No. 5 tang

must be applied and horizontally inserted into the hole of tailstock quill so that it engages with the stop dog, which can prevent the tang from rotating and maintain the accuracy of the taper hole. d) The lead screw is designed for cutting threads not for longitudinal feeding of work piece.

Feeding might affect the service life and accuracy of lead screw. Since the apron is driven directly by the lead screw when threading the safety clutch in apron become useless. Take care to choose a proper depth of cut and a proper cutting force Px not larger than 3500N. e)

Properly lubricate the bearing surface of workpiece when steady rest or following rest is

used to support it. f)

Be sure to stop the main motor prior to workpiece loading/unloading or before the

operator leaves.

10 Adjustment and structure

10.1 Machine bed The main motor is located in front support and the coolant pump is located in rear support of the machine (Coolant pumps for machines with 2M or longer center distance are located in middle support). Electric switchboard is located in the window at rear side of the machine. The tension of drive belts must be properly adjusted with the adjusting nuts. See Fig. 10-1. High grade hardened cast bed ways ensure high-friction resistant and maintenance of accuracy in a long time.

10.2 Headstock This is an all-geared centralized drive headstock. Power from the main motor is transmitted through V-belts to shaft ¢ ñ which drives the spindle by means of multiple-plate friction clutch and several steps of gears. Direction of spindle rotation is determined by the friction clutch. In order to ensure smooth running of spindle the friction clutch must be properly adjusted. It is not allowed to be too tight or too loose. Being too loose may cause not only ineffectiveness and non-sufficient output of spindle power but also frequent slip and heat that will result in serious wear. Being too tight may make it difficult to operate thus losing function of protection. See Fig. 10-2.

The spindle is supported on three bearings of which the front and middle bearings offer main support and rear bearing offers assistant support. In order to ensure the machining accuracy and cutting ability of the machine, play of spindle must be adjusted carefully till radial run-out and axial slip are exactly as the machine requires (See Fig.10-4). 10-2


41/70

5/20/2018



Instructions

When it is necessary to adjust the spindle bearings, loosen nut (1) and nut (2). Be sure to remove the stop washer prior to loosening nut (2). Adjust the spindle front bearing with nut (3) and middle bearing with nut (4) till a proper play is reached. Finally tighten every nut again. After completion of the above procedure, dry run of over one hour must be performed for the spindle. The temperature of spindle in steady state should be no more than 70¡ æ , otherwise readjustment must be made. In order to keep balance and avoid vibration at non-load, a balancer is fixed to gear (5) of spindle. Every machine undergoes a balance check prior to shipment from the factory. (If it is balanced no balancer is fixed.) Torque from gear-shifting mechanical is transmitted by a chain. The chain may stretch after a long use and cause the speed plate to give an improper or wrong value. So it must be adjusted to tension by means of the adjusting screws. See Fig. 10-5.

10.3 Tailstock A stop dog (6) fixed in the taper hole of the tailstock is to prevent the tool held from rotating. The tailstock can move crosswise on the single-direction ways. Cross adjustment is performed with screw (1). Before adjusting be sure to unclamp the tailstock and loosen the screw (2). After completion of adjustment tighten screw (2) again. See Fig. 10-6. When resetting the tailstock, make sure that flanges (8) are in alignment. See Fig. 10-6. The tailstock can move on the bed ways and be clamped and locked in position with the eccentric shaft. The clamping force is adjusted with nut (3) and (4). When tailstock is heavily loaded nut (5) is used to clamp it as well as the eccentric shaft. When the clamping lever is released the tailstock is supported on four rolling bearings with spring seats, clear of bed ways. That makes it an ease for the tailstock to move along the bed ways. The clearance between tailstock and bed ways is adjusted with screw (7). Before adjusting the tailstock should be locked to ensure proper contact between tailstock and bed ways and prevent bearings from being broken.

10.4 Cariage The cross slide is driven by the split nut which moves with rotation of lead screw and is used to eliminates transmission clearance by adjusting the pith diameter fit. When adjusting loosen the stop screw (1) first and then adjust screw (2) till the clearance is removed. After completion tighten screw (1) again and cover the dust lid (3). See Fig.10-7. If the sliding ways of cross slide and compound rest have too large clearance or they are hard to move, adjust the clearance with the adjusting screws at ends of the rack strip.

10.5 Apron The apron controls feeding movements of carriage. Drive from the rod is transmitted to the apron, which in turn drives the carriage to move longitudinally or crosswise by means of safety clutch, worm and transmission gears. In order to make it possible for the carriage to perform rapid traverse at any time the worm is fixed with a one-way overrunning clutch that overpasses the drive from the rod when the rapid traverse motor is driving the worm in a selected direction. When the carriage is moving in rapid traverse mode or auto feeding mode the apron handwheel is disengaged for safety and it is engaged again after the carriage stops. If the cutting force is always below the maximum permissible cutting force of the machine, the safety clutch needs to be adjusted with screw (2). Before adjusting, be sure to remove the cover (1). See Fig. 10-8. Care not to over tighten the clutch. An over tight clutch may lose the function of protection and cause damage to machine parts. To prevent simultaneous engagement of rod and lead screw an interlock mechanism is fixed between the split nut and the operating shaft.

13 Foot brake

13.1 Application and function This brake is designed for stopping the high running main motor and other transmission units of machine. It is simply constructed, efficient, independent and easy to service.

13.2 Structure and working principle Fig.13-1 shows the structure of the foot brake. It consists of pedal, connection rod, support, seat, cam, strain arm, pulley, steel band, braking assembly and electrical unit. As soon as the pedal (6) is trodden, cam (15) will disconnected the over-travel limit switch (16) with the help of strain arm (14), cut off the power to main motor. The motor is thus stopped under the combined action of strain arm (14) and steel band (11). The spindle is unable to re-start unless the starting lever (10) is set to NEUTRAL position.

13.3 Electric unit See Fig. 5-2a for electrical principle diagram of CS6140 series lathes, Fig. 5-3a for wiring connection diagram of CS6140 series lathes. See Fig. 5-2b for electrical principle diagram of CS6140B series lathes, Fig. 5-3b for wiring connection diagram of CS6140B series lathes. 13.3.1 In addition to the instructions herein, user should read item 5 “Electrical part of the machine” for principle of the foot brake. The main motor of machine can’t be started unless the starting lever is set to NEUTRAL position. See Fig.13-1. When the starting lever (10) is set to NEUTRAL position, dog (17) operates and close SQ3 of limit switch (18). In this case the contactor is closed when SB3 or SB4 (KM1) is depressed, and the main motor is operatable. When it is necessary to stop the rotating spindle, step on pedal (7) and the limit switch (16) is switched off, meanwhile the main motor is disconnected to a stop. The main motor can also be stopped by depressing SB2 or SB5 and it can not be restarted unless the starting lever is set to NEUTRAL position. During turning operation control circuit can be disconnected by depressing SB5 in a case of emergency.

13-1


63/70

5/20/2018



Instructions

13.3.2 Adjustment When starting lever is set to NEUTRAL position, dog (17) should be adjusted so that SQ3 of limit switch (18) is in a compressed state. Some adjustment should be made so that limit switch (16) is in non-compressed state when no pedal is stepped and in compressed state when pedal is stepped. See Table 5-1 for list of electrical parts.

13.4 Setting up The swivel angle of pedal (7) is changed by adjusting the length of steel band (11) using the nut of tightening screw rod (12). The height of pedal (6) is changed after loosing the pressure rod (7). The pedal must be locked again after adjustment. Cam (15) is adjusted so that the machine brakes to a steady stop when limit switch (16) is switched off. Limit switch (18) should be adjusted so that it is closed prior to starting of spindle.

When operating, I-shaped sliding block (3) moves along plate (4) and sliding slot (5) along scale (6) that is connected with graduation plate (7) with taper pins.

14.4 Setting up Before using, the scale, which swings back and forth around the shaft pin of the graduation plate, must be properly adjusted so that it points to the correct graduation mark as required by the work piece to be turned. Rotate the adjusting screw arbor till the scale is pointed in position and fasten it to the graduation plate with two T-slot screws. During operation the tool will move a path of taper, thus a taper is turned. During taper turning some length of cylindrical surface is always cut due to mechanical backlash. So it is necessary to take a test operation to find the length (it varies with different taper work pieces).

After setting up the tool, true turning cannot be taken unless the

said length is eliminated by moving the carriage the same distance to the right using the apron handwheel.

14.5 Caution When the taper turning attachment is not to be used bracket (8) must be removed. Some adjustment should be made so that the scale is pointed to zero. Fasten the T-slot screws (12) and lock the I-shaped sliding block (3) using two pointless set screws (13) to stop the lead screw (14) from sliding back and forth. When it is necessary to check the terminal block, take off the taper turning attachment first. Every running parts of the attachment should be lubricated from an oil gun every shift of work to reduce wear of parts and maintain the working operating accuracy of the attachment.

Instructions

15 Mechanical Feed Stop

The machine is designed with a m echanical feed stop, which automatically stops the longitudinal and crosswise feed motion of carriage at a desired position. During feeding, the carriage stops at the position where a dog is pre-set. That is, the lever located in apron, once come into contact with the dog will disengage the jaw clutch mounted on worm shaft in apron. The jaw clutch in turn will stop the carriage. Six adjustable dogs, mounted on the positioning rod that is fixed with machine bed, are used to stop the longitudinal feed. Crosswise adjustable dogs, mounted on the carriage, are used to stop crosswise feed. Note: The mechanical feed stop is ineffective during rapid traverse motion of carriage.
