Power - Performance - Precision
- bed, columns and travel tracks form a solid frame structure for high rigidity under hard machining conditions and high table loads
- triple linear guides support the table across its entire travel distance in the X axis and allow high table loads
- all axes feature preloaded ball screws, preloaded spindle nuts and powerful drive motors
- quadruple linear guides of headstock on Z axis ensure maximum rigidity even with extra-long lay-outs
- the included hydraulic spindle gears allow a wide speed range and high torque
- including weight balancing system for easy movement and precise Z axis positioning
- the main spindle features an oil cooler to ensure constantly balanced temperatures
- quick tool changes via a tool-changer with dual-arm gripper
- Fanuc 0i MD control with Manual Guide for easy programming and maximum reliability
- chip conveyors on both sides of the table with a capacity of 55 kg/min ensure quick chip removal from workspace; including chain-type chip conveyor
- Productivity and flexibility can be increased even further by using any of the optional accessories: NC – Rotary Table, 90° Angle Cutter (more accessessories upon request)
- automatic central lubrication system
