Diameter 55mm lead screw for Tr55x9

The screw processing originally used turning processing. The process route is: cold drawing→knurling→threading→correction→drilling→cutting→chamfering, which is not only low in efficiency and high in cost, but also due to the low rigidity of small round steel, turning and knurling It is easy to deform and the small screw wheel cannot be produced. For this reason, we designed a whirlwind milling screw equipment, which not only increases the speed from about 1000r/min as determined by experience to more than 2000r/min, but also completes the milling knurling at one time. The process route becomes: cold drawing→knurling, wire milling→correction→drilling, cutting→chamfering. Although whirlwind milling makes small-diameter workpieces have greater deformation (large-diameter parts have less deformation), correction is also easy. The improved process has the following characteristics:

The surface roughness value decreases;
Reduced vibration caused by cutting force;
The cumulative error of the pitch of small diameter workpieces has a certain increase.
