ID/OD Cylindrical Grinder

RC-Grind 18100ID/OD Cylindrical grinder

This ID/OD Cylindrical Grinder features the grinding spindle mounted on both sides in adjustable 3-segment bearings. The hydrostatic bearing of the main spindle produces a film of oil between the bearing and the spindle. This eliminates vibration and provides high precision and surface quality, also increasing the service life of the spindle. Precisely aligned spindle head and a sturdy table for best results in different applications. The machine table swivels in 2 directions. Table movement is carried out manually by hand wheel or automatically via the hydraulic feeder in the longitudinal direction. The table feed rate is infinitely adjustable and a delay can be adjusted into the end of the table movement. Accuracy according by ISO for ID/OD Cylindrical Grinder machines. Rapid traverse can be hydraulically or manually actuated.

The 7″ center height is paired with a 12.5″ grinding capacity (2.3″ with res). The grinder can hold up to 330 lbs of workpiece weight. The internal grinding diamer is 1.4-3.9″ with rest and 1.1-3.9″ without. The maximum internal grinding depth is 4.9″ and the grinding spindle size is 0.6×0.8×0.2″ to 2x1x0.5″.

When it comes to accuracy, the RC-Grind 18100 has a radial runout deviation of 0.0012″ and axial runout deviation of 0.00023″. The roughness accuracy is RA≤0.32.
