Conventional Lathe CA-B, CA-C

Main Features
CA-B, CA-C series conventional lathes are developed from CA-A series. Spindle bore of CA-B series is 80mm, while CA-C series is 104mm. CA-B and CA-C series conventional lathes have the same technical data except for spindle bore, spindle speed and taper of spindle nose.

Applications
These conventional lathes can cut various metric, Whitworth, module, and diametral threads.
These lathes are capable of performing conventional turning, facing, drilling, reaming and broaching.
