Product Description
This machine is a two axis (X-axis, Z-axis) CNC Internal Grinder, primarily used to grind inner holes, step holes, inner end faces, and outer end faces. The grinding cycle is completed automatically including automatic feed, withdrawal, rough grinding, fine grinding, wheel dressing, and compensation.
The machine tool is fixed by the work piece box; the worktable moves left/right while the grinding wheel frame handles back/forth feeding. Movements are driven by servo motors through ball screws with linear guide rails.
Spindle speeds for both the work piece and grinding wheel are controlled by frequency converters for stepless speed regulation.
Equipped with a front movable operation box and an independent electrical cabinet. Protective covers are available in semi-closed or fully closed styles.
