The company specializes in manufacturing CNC lathe upgrade screw features:
1. Double pre-drawing method is adopted, two bearings are used before and after, and the screw rubber ring is thickened, the accuracy is more stable!
2. The use of Japan NSK 25TAC62B bearing, which makes the contact surface longer and has certain advantages for complex products. (Type 2047 is generally used, or the front is 2562, the rear is 2047)
3. Screw shaft diameter is R32 plus large screw, C3 precision level, (300L arbitrary detection, accuracy reaches 0.008mm)
4. The bearing seat and tail seat of the fixed screw are the contact points of the shovel processing, and the others are generally polished by the grinding machine, using the scraping method, and the accuracy cannot be guaranteed!
