Stainless Steel Tr5x4 Lead Screw

Good quality Trapezoidal Lead Screw Tr5x4

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.
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.
