Acme screw thread is to ask for a key component in the movement precise movement, the main use of high-quality alloy steel processing, heat treatment process to ensure its excellent mechanical properties, in the manufacturing process, separate coarse and fine process, effectively ensuring stress components equitable distribution of trapezoidal screw manufacturers, the key process in the heated workshop process, a stable temperature, to ensure that all indicators meet the national standard high-precision screw JB / T 2886-1992 Machine acme screw, nut technical conditions related to the acceptance criteria. Keystone Ball accuracy class and acceptance criteria: R logo screw trapezoidal screw, right-handed screw is generally not marked. 7 screw - for precise drive, precision screw machine tools, Exon grinder, surface grinder feed exercise. Analysis and comparison of trapezoidal screw screw machining process of turning the original use, process route is: cold drawn → knurled threading → → → → drilling off → correction chamfer trapezoidal screw repair, not only inefficient, high cost and due to the small round low stiffness, turning, easy to deform when knurled trapezoidal screw specifications, trumpet snail wheel can not be produced, for which we designed a whirlwind milling screw device, not only by experienced certified speed 1000r / min or so up to 2000r / min or more and will be completed once the knurled silk mill. The process route becomes: cold drawn → knurling, milling and wire → correction → drilling off → chamfer. Although the small diameter of the workpiece Whirling greater deformation (deformation of large diameter is smaller), but also easy to correct. The improved process has the following characteristics: a surface roughness value decreases; 2 reduction caused by the vibration of the cutting force; 3 trails workpiece pitch a certain increase in the accumulated error....
