CM Series
Powerful conventional turning technology
Robust construction for medium-sized and demanding workpieces
The COMEV CM is a conventional center lathe for precise machining of medium-sized workpieces.
Its robust construction allows for medium-heavy machining without sacrificing the sensitivity and direct control of a conventional lathe.
With a 110 mm spindle bore, a swing diameter over the bed of up to 800 mm, and turning lengths of up to 4,000 mm, the series is also suitable for larger shafts, flanges, bushings, and repair parts.
For precise medium-duty machining
Generous workpiece capacities
Robust spindle and bed construction
Direct and sensitive operation
Powerful and controllable
High machining capacity combined with the direct operation of a conventional lathe.
Construction and technology
Designed for precision, stability, and long service life
High-quality mechanical assemblies and generously sized components form the basis of the CM series.
110 mm spindle bore
The hardened and precision-ground main spindle features an 8-inch Camlock mount and runs in high-precision tapered roller bearings.
72 feeds without change gears
The enclosed, oil-bath-lubricated Norton gearbox provides 72 longitudinal and cross feeds as well as numerous metric, Whitworth, module and diametral-pitch threads.
Stable and sensitive to operate
The generously sized saddle and cross slide provide high rigidity while remaining precisely controllable during manual infeed movements.
400 mm bed width
The wide machine bed provides a stable foundation for precise machining and high cutting performance, even with long workpieces.
Robust tailstock with MK 5
The hardened and ground tailstock quill has a diameter of 100 mm, a stroke of 300 mm and an MT5 taper.
Machine details
Thoughtful operation for daily use
Clear control elements, good accessibility, and robust components facilitate setup and machining.
Clear workspace
The workpiece, toolholder and tailstock remain easily accessible and can be set up directly.
Rigid carriage package
Generously dimensioned guideways and mechanical handwheels enable controlled infeed movements.
Digital position display
The digital readout assists the operator with precise infeed movements and monitoring of axis positions.
