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 door; effective splash protection with excellent accessibility

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

Grinding spindle separated from motor via coupling, 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 left-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
