Features:
1. Made of high quality steel material for long life
2. Small body and stable performance
3. The nut is designed without wind to ensure more stable machining to ensure at high speed.
4. It has high heat and oxidation resistance, strong toughness and high wear resistance.
5. The close interaction of the cutting force of the tool on the workpiece with the column reduces the resonance and makes the machining accuracy more stable.
