Surface grinding machine F-Grind Advance

column typeCNCautomatic

The precision-ground guideways of the F-Grind Advance NC surface grinder are coated with TURCITE B to have a low-friction surface. Stick-slip is reduced drastically between the two precision surfaces. Furthermore, the surfaces allow for very quiet motion and are highly resistant against wear. Lubrication The spindles have special sealed bearings and are lubricated for the service life, that ensuring minimal servicing. The guideways are automatically supplied with oil straight after activation of the hydraulic system. Lack of oil is thus never a problem. In addition, an automatic alarm system warns the operator in case of a low oil level. Basic machine parts annealed for stress relief The frame, the table, the support, the column, and all other main machine castings are quenched and tempered twice. This minimizes all metallurgical stresses. Heavy gray cast iron frame optimized by FEA analysis X and Z axes are laminated with Turcite B Precision cartridge spindle with high rigidity Precision grinding spindle with class P4 bearing ensures quiet and vibration-free spindle travel of 2 μm X axis feed controlled by steplessly adjustable proportional valve Y and Z axes driven by digital AC servo motors Partial housing for reduction of spray Manual axis feed joystick option Steplessly controllable spindle speed through inverter technology Automatic dressing unit with integrated compensation for a significant increase in productivity Accuracy according to DIN 8632 Including automatic grinding cycles (flat, cross, groove, spark-out, dressing)
