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, right-handed screw is generally not marked. 7 screw - for precise drive, precision screw trapezoidal screw lathe Buy, Exon grinder, surface grinder feed exercise. Trapezoidal thread screw machining processing methods Whirling thread screw machining and knurled once completed high process efficiency, low cost, precision requirements are not too common trapezoidal screw products, structural design ideas, there are better solutions The application value. Whirlwind milling method is an efficient thread processing method for large quantities of rough thread, the process is carried out with a carbide blade for high speed milling trapezoidal screw thread, it has tool cooling, high production efficiency advantages. Less precision thread, this method can be a complete machining. Whirling knife rotation axis and the axis of the workpiece for spatial relationships, cross angle β angle (equal helix angle). Which process comprises a rotational movement of the workpiece, the helical axis of the workpiece feed movement (or tool feed), the rotational movement of cutter blade.
