Precision Granite Right Angle Square

Product features:

This granite right angle square adopts integral fine grinding and polishing processing, with no splicing joints on the two working surfaces, ensuring the accuracy of the squareness between the two planes. Each product has passed strict squareness calibration, reaching Grade 00 accuracy standard, with a squareness error of less than 2 seconds per 100mm. The surface roughness reaches Ra≤0.08μm, which can reduce the wear of the workpiece during measurement and avoid scratch damage to the surface of precision workpieces. It has good thermal stability, with a thermal deformation of less than 0.15μm per 1℃, ensuring accurate measurement results in different workshop temperature environments. The product has been specially treated on the edges to improve shock resistance, avoiding chip damage during transportation and use. It also has good acid and alkali corrosion resistance, adapting to complex industrial environments such as mechanical processing and metal surface treatment workshops.

Product application:

This precision granite right angle square is mainly used in mechanical processing workshops, mold manufacturing plants, hardware testing centers and precision instrument assembly lines. It can be used to detect the squareness of machine tool workbenches, the verticality of fixture positioning blocks, the right angle of hardware parts, and the positioning accuracy of coordinate measuring machines. In the mold manufacturing industry, it is used to calibrate the squareness of mold core plates and sliding blocks; in the hardware processing industry, it is used to detect the right angle of small hardware parts such as hinges and brackets. It is an important auxiliary measuring tool for improving the processing accuracy of mechanical parts.
