Acme screw thread asking for precise movement in motion a key component of general trapezoidal screw, mainly made of high quality alloy steel processing, heat treatment process to ensure its excellent mechanical properties trapezoidal screw samples during the manufacturing process, coarse and fine process separately, effectively ensuring a reasonable distribution of the stress components, 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 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 screw lathes, grinders Exon trapezoidal screw, surface grinder feed exercise. Acme screw trapezoidal screw bearings to adapt to use a variety of purposes, providing a wide range of standardized products. Widely used in machine tools, ball circulation methods are circulating duct type, circulator type, cover type. Preloading way positioning preload (double nut way preload-bit mode), constant pressure preload. May be appropriately selected according to the type of use. There are high-precision grinding screw precision ball screws (accuracy divided from CO-C7 of six levels) and by high-precision cold-rolled ball screw bearings molding (precision into the C7-C10 3 levels). In addition, users need to cope with the delivery, there has been carried out on the shaft end product processing can be carried out freely on the shaft end processing of semi-finished and cold-chase ball screw bearings. As part of this bearing peripheral components necessary for the use of screw support unit, bearing nut, lock nut, etc. have also been standardized trapezoidal screw type, to choose to use. Acme screw bearing accumulated over the years to the technology-based products, from materials, heat outside the grounds, manufacture, inspection to shipment, are based on strict quality assurance system to be managed, and therefore has high reliability.
