Crusher, bearing housings, stands of SMS are taken up. Over 100 major machines including lathes, milling, Plano milling, boring, slotting, shaping, grinding etc. are available to take up machining of spares. 2 presses of 630 ton, 315 ton and dynamic balancing machine of 25 ton capacity, are provided at CMS for repair of assemblies.
BORING MACHINES Boring is similar to turning. It uses a single-point tool against a rotating workpart. The difference is that boring is performed on the inside diameter of an existing hole rather than the outside diameter of an existing cylinder. In effect, boring is an internal turning operation. Machine tools used to perform boring operations are called boring machines (also boring mills).
completing processes that reduce cutting times even further. In Europe, on the other hand, the old face milling, five-cut was replaced by the Gleason face milling completing. The single-indexing completing method also uses cutter heads with stick blades, which in connection with fast indexing CNC machines achieves a similar productivity
