The heavy-duty E-Series
Electronic operating convenience for heavy-duty machining
The CMXE expands COMEV's electronic lathe range with an exceptionally robust series for large, long and difficult-to-machine workpieces.
The 500 mm wide machine bed and high machine weights create a stable foundation for demanding roughing and finishing operations.
At the same time, operation remains direct and workshop-oriented. The operator works right at the machine, supported by electronic feeds, digital position displays and a modern control panel.
Exceptionally robust machine construction
Direct operation without complex CNC programming
Electronically controlled X and Z axes
High repeatability with heavy workpieces
Greater stability for heavy-duty tasks Large workpiece capacity combined with modern, electronically assisted direct operation.
The CMXE concept
Between a conventional lathe and CNC
The CMXE is ideal for companies that want to machine heavy workpieces flexibly without having to create a complete CNC program for every job.
02
Electronic assistance
Spindle speed, feeds and axis movements are controlled electronically and can be flexibly adapted to the workpiece and tool.
03
Direct working method
The operator remains directly at the workpiece and retains control of the machining process without conventional CNC programming.
Technology and performance
Designed for powerful and precise machining
The combination of a wide machine bed, powerful main drive and high axis thrust provides ample reserves for heavy workpieces.
500 mm wide bed construction
The generously dimensioned bed provides high rigidity and low-vibration machining over workpiece lengths of up to 6,000 mm.
24 / 18 kW spindle power
The powerful main drive provides ample power reserves for large diameters and heavy machining cuts.
Separate drives for X and Z
The axes are electronically driven, enabling smooth, precise and freely adjustable feed movements.
3 m/min on both axes
Rapid traverse enables fast positioning over long machine travels and reduces non-productive time.
Up to 1,200 daN on the Z-axis
High feed forces support powerful and consistent machining under increased tool loads.
110, 130 or 160 mm bore
Different spindle variants allow adaptation to pipes, hollow shafts and larger through-workpieces.
Modern E-Series controls Set and monitor positions, speed, feed and machine functions directly at the workstation.
Direct and clearly arranged
Electronic functions without complex programming
The machine is designed for experienced turners and workshops that want modern drive technology while continuing to work directly at the workpiece.
Infinitely variable speed control The spindle speed is set to suit the diameter, material and tool.
Electronically adjustable feeds Longitudinal and cross feeds can be flexibly adapted to each machining task.
Digital position monitoring The current axis positions are displayed clearly and immediately.
Fast positioning Electric axis drives and rapid traverse support short setup and positioning times.
Machine details
Well-engineered technology for heavy-duty workshop use
The headstock, carriage and controls are designed for easy access, high stability and safe operation.
Clear operator display
Machine values and functions are displayed and adjusted directly at the work area.
Heavy-duty working area
The generously dimensioned components support high cutting forces and precise tool movements.
Integrated machine concept
Drive technology, safety systems and controls form a functional unit for daily use.
