Trapezoidal screw standards, Korea and Taiwan transmission machinery (certified), trapezoidal screw

 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 design, the key process in the heated workshop trapezoidal screw machining factory, stable temperature, to ensure that all indicators meet the national standard high-precision screw JB / T 2886-1992 Machine acme screw, nut technical conditions relating 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 lathe screw trapezoidal screw material, Exon grinder, surface grinder feed exercise. Threading method trapezoidal screw drive at high precision lead screw threads, you need to ensure that low-speed turning trapezoidal thread precision and smoothness, precision lead screw turning process is as follows: 1] screw thread and accuracy is not less than 4mm High artifacts available trapezoidal thread by turning around to the method using the roughing and finish turning. 2] is greater than 4mm screw threads and higher precision trapezoidal screw thread, the general method of turning points knife. 3] roughing, leaving about 0.3mm margin semi-intensive car trapezoidal screw thread, over time, and the screw thread chamfer the end face 15 degrees. 4] with coarse roughing tools, using about cutting method or straight turning, (leaving each side 0.1-0.2mm finishing allowance), the choice of blade width is slightly smaller than the groove width of the car low slot. 5] selection of fine cars trapezoidal screw thread turning, cutting method using the left and right sides of the trapezoidal screw thread fine cars, fine after turning angle of 0 degrees forward, the tip is equal to tooth type angle, both sides of the cutting edge mill have larger volumes rake angle cut grooves, turning the front can not participate in cutting.
