Features:
1. Made of high quality steel material for long service life
2. Small body and it has stable performance
3. The nut is designed with no wind resistance to ensure more stable machining at high speed.
4. It has high heat strength and oxidation resistance, strong toughness and super wear resistance.
5. The close cooperation of the cutting force of the tool on the workpiece to the guide column reduces the resonance and makes the machining accuracy more stable.
