Yong Wei mold steel, SUS440C die steel, SUS440C provided by Yong Wei steel mold. We are a steel mold, Dongguan City, An Yongwei shop (www.dgyongwei.com) located at: Dongguan specializes in: mold steel one, high-strength cast iron bed, the internal stress relief SUS440C prices, so that the material stability, precision unchanged, most suitable for continuous stamping production. 2, double guide column, a central pillar structure, using zero error to replace the traditional ball bearing slide structure, the dynamic friction to a minimum, with the forced lubrication to minimize thermal distortion and highest precision. 3, optional reverse side move to reduce vibration balancing device SUS440C rod, make punch with the best accuracy and stability. 4, manual transfer mode SUS440C, with high display mode and hydraulic locking device to facilitate transfer mode operation. 5, HMI microcomputer control, numerical, fault monitoring system, the screen display for easy operation. Diamond grinding wheel with diamond abrasive grains as the raw material, respectively, with a metal powder, a resin powder, ceramic, and metal plating as a binding agent, made into various shaped articles, for grinding, polishing, grinding tool called diamond abrasive. Diamond abrasive structure: diamond abrasive layer structure generally consists of work, the matrix, transition of three parts. Working layer, also known as the diamond layer, SUS440C die steel by abrasive, binders and fillers, is abrasive working parts. Also known as the non-diamond layer the buffer layer, the binding agent, metal powder and a filler, is firmly connected to the part on the substrate of the diamond layer.
