Main feature:
1.The longitudinal movement of the table and the lateral feed of the grinding head are all hydraulically driven, stepless speed regulation, and the lateral feed can also be manual;
2.The vertical feed motion of the machine tool uses a ball screw pair and the feed sensitivity is high. The grinding head adopts built-in motor, compact structure, good rigidity of the spindle and high precision;
3.The vertical feed of the grinding head is manual, equipped with a quick lifting mechanism, which can reduce labor intensity and improve work efficiency.
Product Description
This series of machine tools grinds around the grinding wheel to grind various workpiece planes made of steel, castings, non-ferrous metals, glass, ceramics, etc. Suitable for all kinds of mechanical processing workshops and machine repair workshops.
