ACME 11/16-5 lead screw with square nut

A lead screw is a difficult-to-machine sliding feed screw with a 45° lead angle. Its large lead angle is best suited for fast reciprocating feed at low speeds.
Can easily convert linear motion to rotary motion and rotary motion to linear motion with 70% efficiency. Because of the large lead, it is most suitable for the manufacture of fast-forward mechanisms that rotate at low speeds
Turning was used for lead screw processing. The process route is: cold drawing→knurling→threading→correction→drilling→cutting→chamfering. It is easy to be deformed at times, and the small screw wheel cannot be produced. For this reason, we have designed a whirlwind milling screw equipment, which not only increases the speed from the experience-recognized 1000r/min to more than 2000r/min, but also completes the milling and knurling at one time. The process route becomes: cold drawing→knurling, wire milling→correction→drilling, cutting→chamfering. Although whirling milling causes large deformation of small-diameter workpieces (smaller deformation of large-diameter workpieces), correction is also easy. The improved process has the following characteristics:
The surface roughness value decreases;
Vibration caused by cutting forces is reduced;
The cumulative error of the pitch of the small-diameter workpiece increases to a certain extent.
