High-grade castings

　　The core frame of the equipment adopts high-grade QT500-7 and HT300 castings, and the castings are measured by testing instruments. The frame has undergone precise finite element stress analysis and adopts a stable triangular interconnection design, which greatly ensures stability under high-tonnage impact.

　　High-standard welding

　　Carbon dioxide shielded welding is used throughout the welding process, and full welding technology is used at the welding point to ensure that the welded workpiece is firm and beautiful.

　　Stress relief treatment

　　The castings and welded support tables use high-precision temperature control furnaces, and perform multiple tempering, annealing and other heat treatment processes according to the temperature curve corresponding to the material, and then perform long-term full-frequency vibration aging treatment to release the internal stress of the workpiece and prevent deformation during long-term use.

　　Precision machining

　　Different tooling fixtures are designed for different workpieces, and high-precision multi-axis machining centers are used to fine-process the workpieces to ensure the consistency of accuracy before and after clamping.

　　Strict testing

　　Using high-precision micrometer U-meters, marble platforms and marble squares with long service life, we can accurately measure each workpiece, strictly control the processing quality of each workpiece, and check every level to ensure that the assembly accuracy of the whole machine meets the high-precision machine tool standards.
