OVERVIEW OF THE KMC 250-S
Ideal for medium and short runs, prototypes, over-sized parts and steel mold making. Every machine is laser verified for ±0.0004” positioning accurac y over full table travel. ±0.0001” repeatability with 0.0001” resolution. 7.5 HP (30 minute duty rating) spindle motor with high-low geared head. 24” x 14” x 6” work envelope with 750 lb. table load capacity. Easy loading and unloading of work pieces. Greater flexibility provided by the sliding ram.
TECHNICAL DESCRIPTION OF KEY FEATURES
M eehan ite Castin g - Machine frame is cast of rugged
Meehanite with heavy ribbing for superior rigidity and vibration dampening. This rigidity contributes to durability of machine and tooling, as well as precision of actual machining performance.
Ul tr a-Precision B all L eadscrews - Precision-ground, zero-
backlash, 1-1/4” diameter, reciprocating ball leadscrews pr ovide ±0.0001” repeatability over full length of table travel.
Box Ways and Dovetail Gu ides - Extra wide square box ways support the saddle, while
dovetail guideways are used for accuracy alignment. Ways are hardened and ground to a 16 microinch finish, and bearing surfaces are coated with Turcite-like material for nearfrictionless table motion.
Ram Constr ucti on – A sliding ram allows for flexibility in machining over-sized and odd -
shaped parts. Solid ram construction is also available.
Spindl e Power - At ONLY 58 RPM of the cutter, the programmable speed spindle motor
reaches its full horsepower rating (7.5 HP — 30-minute duty rating) and produces 679 ft-lb. of torque, allowing for the accurate removal of mo re than 8 cubic inches per minute of steel, depending on cutting parameters.
- The 4-3/8” diameter, hardened and precision-ground quill is 14-3/4” H eadstock Over lap
long, and is supported with precision P-4, Class 7 angular-contact spindle bearings. When fully extended 6” along the Z-axis, the quill has 8” of overlap housing support for chatter free milling and boring.
Z-Axi s Leadscrew M ountin g - The Z-axis leadscrew is
mounted at a minimum distance from the quill, resulting in accurate axial positioning and superior deflection resistance. Milling rigidity is greatly enhanced.

L aser Veri fi cation - All KMC’S are laser verified for ±0.0004” positioning accurac y over the
full X and Y table travel axes before being shipped.
Un iqu e Standard F eatur es - The KMC 250-S is the only CNC Knee Mill in its class that:
is built by the machine tool builder from the floor up is U.L. and D.O.D. approved has double automatic lubrication has square ways for rigidity and dovetail guides for accuracy
