The modern COMEV solution for quickly manufactured CNC turned parts
The CDR 20 expands the COMEV program with a compact slant bed machine for productive CNC machining. It was designed for companies that require short cycle times, effective chip removal, and reproducible precision.
The slant bed allows chips to fall freely out of the working area while the turret, chuck, and tailstock remain easily accessible.
The machine is suitable for both flexible single orders and recurring small, medium, and large series.
Dynamic X and Z axes
Eight tool stations with VDI 40
ISO, Fanuc, and dialog programming
Expandable for automated manufacturing cells
Compact and productive Only 2,450 mm machine length with full CNC working space.
The CDR concept
Fast processes and reliable process control
The combination of slant bed, automatic turret, powerful CNC, and optional automation forms the basis for economical series production.
02
High axis dynamics
Rapid travels up to 30 m/min on the X-axis and 20 m/min on the Z-axis reduce non-productive times.
03
Manufacturing prepared for automation
The machine can be expanded into a manufacturing cell with a robot, workpiece feed, and automatic loading and unloading.
Short travel distances in the working area Turret, clamping chuck, and tailstock are compactly and manufacturing-friendly arranged.
Production technology
Designed for short cycle times
The CDR 20 combines fast positioning movements with a compact working area and an automatic eight-station turret.
01
Main spindle speed: 4,200 rpm
The wide speed range supports both smaller precision parts and demanding machining operations up to 300 mm in diameter.
02
Tool system VDI 40
Eight tool stations enable flexible combinations of turning, drilling and optional driven tools.
03
Integrated chip conveyor
The standard chip conveyor supports continuous machining and reduces manual cleaning work.
04
Protected working area
The full machine enclosure protects the operator and safely contains chips and coolant within the machine area.
Z32 CNC and Lathe++
Flexible programming for different users
The PC-based Z32 control operates on a real-time Linux platform. Programs can be created in ISO standard, in Fanuc-oriented G-code, or interactively with Lathe++.
Dialogprogrammierung mit Lathe++ Machining sequences are created using clear inputs and graphically supported cycles.
ISO-Programmierung The complete ISO programming environment is available to experienced CNC users.
Fanuc-orientierter G-Code Existing programming experience and many existing programs can be transferred more easily.
Anpassbare Software COMEV and D.Electron can adapt control functions for special machining processes.
Integrated machining cycles
Prepared for typical turning operations
The CNC supports numerous practical cycles for turning, drilling, threading, and milling operations.
Roughing Efficient material removal with automatically generated roughing paths.
Preliminary machining Preparing the contour for uniform, precise finish machining.
Finishing Precision finishing of cylindrical and profiled contours.
Face turning Guided machining of end faces and shoulders.
Grooving and parting off Programmable grooves, recesses and undercut contours.
Thread turning Cylindrical and tapered threads with defined pitch and infeed parameters.
Drilling Axial drilling with stationary or optionally driven tools.
Polygonmilling Production of polygonal contours with the appropriate machine configuration.
Slot milling Machining grooves and keyways with optional driven tools.
