Locating threaded posts belong to a class of standard fasteners, usually used in machinery, and are part of mechanical equipment.
Threaded column: threaded column generally has threads at both ends (single-headed studs are threaded at one end), usually one end of the thread is firmly screwed into the body of the component, and the other end matches the nut to play the role of connection and fastening. But to a large extent, it also has the effect of setting distance.
Unequal-length double-ended threaded column: suitable for occasions where one end is screwed into the component body for connection or fastening. See GB897-900, etc.
Equal-length double-ended threaded column: It is suitable for matching the connecting end with the nut, and plays the role of connection or distance fixing. See GB901, GB953, etc.
Threaded column standard fasteners are also one of the precision five precision products of Shenzhen Jingtian Precision Technology Co., Ltd. Shenzhen Jingtian Precision Technology Co., Ltd. is mainly engaged in the production of metal precision parts. It has CNC numerical control lathes, numerical control machining centers, automatic lathes and other equipment, as well as research and development and production of production automation equipment.
The company has more than 20 years of experience in non-standard car parts, milling parts production, mold equipment development and production automation; it has nearly 300 advanced production equipment imported from Japan and Taiwan and various high-end precision testing equipment, with modern management and professional The technical development team has passed the international quality management system ISO9001: 2015 certification and the automotive industry production parts and related service parts quality management system IATF16949: 2016 certification and other management systems.
This threaded column production process produced by Jingtian Precision Hardware mainly includes CNC turning/machining and CNC milling. This type of product has very high requirements on the precision tolerance of the inner and outer diameter of the hole and the surface roughness!
CNC turning or machining and CNC milling are mainly for cutting and processing the inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of any cone angle, complex rotary inner and outer curved surfaces, cylinders, and conical threads, etc., and can perform grooving, drilling, etc. Holes, reaming, reaming and boring etc.
The positioning thread column produced by Jingtian Precision Hardware is made of 12L14. 12L14 is a free-cutting structural steel. Steel for automatic machine tool processing, referred to as automatic steel. It is produced to adapt to mechanical processing automation and assembly line production.
The surface treatment of this positioning threaded column produced by Jingtian Precision Hardware adopts environmentally friendly galvanizing. The production process of ordinary galvanizing uses high-priced chromium, which is toxic to heavy metals, while environmentally friendly galvanizing uses low-priced chromium or chromium-free passivation. Environmental protection is mainly reflected in the passivation process, suitable materials for environmentally friendly galvanizing, and various metal materials: such as carbon steel, iron, zinc alloy, aluminum, etc. The characteristics of environmentally friendly galvanized appearance are beautiful, anti-corrosion and anti-rust, and good smoke performance.
