1. Product Description
Suitable for: High-precision professional large-scale processing factory, blade factory, hardware accessory factory, board processing factory, printing plant
- The lateral side of the machine tool adopts national standard double steel plate and lining stiffener. The bottom plate is welded by flat and thick steel plates, which have been subjected to special treatment to sufficiently ensure that the whole machine tool is stable, and free from vibration and deformation.
- The travelling support plate of the machine tool is made of cast iron through precision machining to avoid potential deformation.
- The travelling system of the machine tool adopts prevision gear reducer which works with the pinion and rack as well as the frequency converter to ensure travelling stability, and greatly improve the grinding quality and operational efficiency.
- The grinding head part of the machine tool adopts rapid hoisting device, which makes the replacement of the grinding wheel more convenient and rapid, improves the operational efficiency, and reduces labor intensity. The thickened ball screws inside work with the adjustable precision nuts to facilitate the adjustment of the axial clearance of the screw rods. The grinding head adopts the grinder motor of national standard and is reasonably designed to improve the grinding precision and prolong the service life.
- The towing chain is made of premium steel, which can be used perpetually without damage.
- The electromagnetic chuck is excellent in quality, durable and in line with national standard, which ensures less heat generation, great suction force and long service life.
- Adopts double grinding heads, which can deliver both coarse and find grinding, thus improving the efficiency and precision
