1, strong structure: the fuselage is made of FC-25 high-strength ductile cast iron, and by tempering heat treatment, durable.
2, the advance and retreat movement is stable: the advance and retreat slide of the square track design is cast with the fuselage as a whole, and will not jump during the rolling pressure operation after grinding.
Loose, worn.
3, strong strength: hydraulic drive, a wide range of processing capacity.
4, fixed, rolling through dual-purpose: equipped with time limit control meter, can adjust the processing time.
5, full transmission: the worm after heat treatment is ground by thread, with phosphor bronze worm gear more closely combined, smooth transmission.
6. Both ends of the thimble support frame can be added according to the type of work, and the thread can be rolled to integrate the concentricity.
7, especially suitable for long ruler screw, ohm screw, ball screw and machinery, hardware tools, steam engine parts or iron pipe thread processing.
