Grinding form and pre-work inspection of semi-automatic CNC internal grinding machine

Jun 17, 2019

The grinding form of the semi-automatic CNC internal grinding machine is divided into three types. One is the intermediate type internal grinding. When grinding, the workpiece rotates around the middle line of the spindle of the spindle box. It is suitable for grinding sleeves, gears, flanges, etc. The inner hole of the part, the workpiece is clamped on the headboard with the chuck when grinding.

 

The other is planetary internal grinding. When grinding, the workpiece is fixed. The grinding wheel rotates around its own main axis, and the circumference is supplied at a lower speed around the middle point of the grinding hole. There is also a grinding wheel feeding longitudinal and periodic lateral. There is also a centerless internal grinding, the workpiece is supported on the support wheel and the pressure wheel by its finished outer circle, and is rotated by the guide wheel, so that the grinding method is suitable for grinding thin-walled ring parts. Bore.

 

Regardless of the grinding form, the semi-automatic CNC internal grinding machine should check the hygiene of each part before cleaning, and clean the surface of the work surface, the corrector, the shield, etc. Clear the ash in the ash tank. Check whether the operating handle, switch, and knob are in the correct position, whether the operation is flexible, and whether the safety device is safe and reliable.

 

Turn on the power, check if the grinding wheel is loose, run the vehicle at low speed for 2-3 minutes, and observe whether the operation is normal. If there is any abnormality, stop the machine for inspection or report. Check if the height indicated by the liquid level in the oil mark is appropriate. If the oil level is insufficient, add the lubricating oil according to the regulations. It is confirmed that the lubrication is smooth and good, and the electrical system and all parts are operating normally.
