80mm GPO3 Parts

Product Description

Strengthen GPO3(UPGM203) high precision machining parts for rail transit thickness 0-80mm


GPO3(UPGM203) material has good insulation performance, mechanical strength and good machinability. According to the use requirements of different structural parts, it can support special-shaped, processing thread, inlaid screw sleeve and other processing technologies

This GPO3(UPGM203)product is used in rail transit equipment, which needs multi-faceted processing and deep hole processing. The machining accuracy is very high. The tolerance of two Φ 30 round holes is required (0, + 0036), and the concentricity of the two round holes is required to be 0.15.
Our company has 10 raw material production lines, which can produce materials of different panel sizes to reduce the loss of raw materials. With more than 100 CNC processing equipment, nearly 30 technical engineer team, and perfect process control process, we can ensure stable product quality and low production cost. At present, we have become the leading manufacturer of ABB, Siemens, Schneider and CRRC
