Operation

Easy and intuitive operation through a large, user-friendly touchscreen
Electronic handwheel, usable in the Y- and Z-axis, switchable in two stages to 0.001 and 0.01 mm

Cast iron/enclosure

Rigid cast iron machine components
High machine weight for maximum rigidity
Partial enclosure of the machine with sliding door and front-mounted service doors; effective splash protection with excellent accessibility
Additional service door at the back, incl. second electric handwheel

Linear guideways

Preloaded precision linear guideways in the Y- and Z-axis (Bosch Rexroth) for highest accuracy

Sliding guideways

Excellent damping characteristics and high surface finish quality thanks to hand-scraped double-V sliding guideways on the X-axis

Lubrication system

Automatic central lubrication in the X-axis (slideway oil) and in the Y- and Z-axis (grease)

Drives

Hydraulic table drive with recooling unit
Electromechanical drive of the Y- and Z-axis

Measuring system

Precise positioning using a direct measuring system on the Y-axis (Heidenhain) and a rotary encoder on the Z-axis

Spindle technology

Belt-driven grinding spindle separated from motor, eliminating heat transfer
Continuously adjustable grinding spindle motor with constant cutting speed up to 35 m/s
(optionally up to 50 m/s) over the entire range of use of the grinding wheel (vconstant)
Long service life due to a grinding spindle supported by 6 rolling bearings, grease-lubricated for life

Magnetic clamping technology

Heat-free electro-permanent magnetic chuck incl. back and right-side stop bars
Integrated pole-reversal control unit with 16 different clamping forces

Coolant system

Maintenance-free belt filter system with integrated channel flushing incl. cleaning gun with hose and magnetic separator for pre-filtration
