Cast iron bent plates are suitable for high-precision mechanical and instrument inspection, as well as checking for non perpendicularity between machine tools. Cast iron bending plate is used for inspecting and installing the vertical surface of machine tools and machinery. It can check the perpendicularity of workpieces on a flat plate, commonly referred to as marking by a fitter.

The material of cast iron bending plate is HT200-HT300, manufactured according to GB6092-85 standard. The working surface of the cast iron bending plate adopts scraping technology, and after two manual annealing processes, the accuracy of the bending plate is stable and the wear resistance is improved.

Cast iron bent plates are manufactured according to GB6092-85 standard, with material HT200-HT300. The working surface adopts scraping and grinding technology, which is used for component inspection and clamping in mechanical processing.

Cast iron bent plates are used to inspect the 90 ° angle of workpieces, check the mutual perpendicularity of relevant surfaces of components during equipment maintenance, and are also commonly used for marking by fitters. And it can be commonly used for inspection, installation, and vertical plane inspection of machine tools, and can check the perpendicularity of workpieces on flat plates. It is suitable for high-precision mechanical and instrument inspection and inspection of non perpendicularity between machine tools.

Precautions for using cast iron bent plates: Do not use and store bent plates in damp, corrosive, high or low temperature environments. Before use, the bending plate should be installed and debugged, and then the working surface of the bending plate should be wiped clean. After confirming that there are no problems, the bending plate can be used.

Cast iron bending plate specifications: 200X200, 300X300, 200X400, 300X600, 300X400, 270X400, 400X400, 500X500, 600X600, 800X800, 800X1000. Note: Various non-standard specifications can be customized
