Feature:
1. FINE PROCESSING: Vacuum quenching treatment can realize carbon oxycarburizing to improve the hardness, and fine grinding can increase the ability.
2. INTEGRATED DESIGN: The inner and outer cone are finely ground, the chuck and the body inner cone are formed at one time, with uniform strength and high concentricity.
3. SOLID STRUCTURE: The back pull clamping design of the handle, and the design of tightening the tie rod screw can prevent the handle from falling off.
4. 40CR ALLOY STEEL: Made of excellent 40Cr alloy steel material, has high hardness and wear resistance, not easy to deform or corrode for a long time.
5. WIDE APPLICATION: Widely used in CNC machining centers, engraving machines and other high speed processing machines, which is efficient and durable.
