Features of Screw
 

The lifting screw of the power frequency quenching machine tool is often made of high-quality alloy steel 45CrMoV, in which chromium improves the steel's oxidation resistance and corrosion resistance, molybdenum enhances strength and hardenability, and vanadium refines the grains while improving toughness.

 

After quenching and tempering, the lifting screw of the power frequency quenching machine tool exhibits an optimized internal organizational structure and excellent comprehensive performance. It can withstand heavy pressure and frequent impacts to ensure long-term stable operation.

 

The lifting screw of the power frequency quenching machine tool features high-precision threads that mesh tightly with the nut for stable transmission, thereby avoiding crawling and meeting the positioning accuracy requirements of the quenching process.

 

The lifting screw of the power frequency quenching machine tool undergoes surface quenching, making it hard, wear-resistant, fatigue-resistant, capable of withstanding friction while reducing cracks, thus adapting to long-term high-intensity operations.

 

The screw has lubrication channels to reduce friction and is equipped with high-performance seals at both ends to block impurities, protect its internal structure, and extend service life.

FAQ

 

 

Q: What is induction quenching machine tool?

A: The Power frequency quenching machine tool lifting screw, composed of a screw and a nut, converts rotational motion into linear motion for workpiece lifting. It's crucial for quenching accuracy and stability. When the screw rotates, the nut moves linearly according to the lead, and the connected workpiece moves accordingly, achieving high - precision lifting control.

Q: Why is power frequency not utilized in machine tool leadscrews?

A: The relatively low frequency results in deep and uniform heating of the screw, thereby increasing the likelihood of thermal deformation and warping—phenomena that are unacceptable in precision components.

Q: What distinguishes power frequency from intermediate frequency?

A: The fundamental distinction lies in the depth of heat penetration, which is determined by the electromagnetic frequency.
