- The machine tool is equipped with a quick retract mechanism, so there is no need to re-manually set the tool after the grinding wheel is retracted for measurement or correction.
- The worktable is started with a hydraulic pressure switch to ensure safety during workpiece loading and unloading.
- For special orders, the machine tool can be equipped with a high-speed grinding wheel spindle with a speed of 18000 rpm, suitable for grinding holes of 20 – 50mm.
- An end face grinding device can be optionally equipped. Under the condition of one-time clamping and loading, the perpendicularity requirement between the workpiece end face and the hole is ensured.
