[0002] A grinding machine is a grinding machine that grinds the surface of a workpiece with a grinding tool coated or embedded with abrasive; it is mainly used for grinding high-precision planes, inner and outer cylindrical surfaces, conical surfaces, spherical surfaces, thread surfaces and other shaped surfaces in workpieces; the main types of grinding machines include disk grinding machines, rotating shaft grinding machines and various special grinding machines. The control system of the grinding machine takes the PLC as the control core and the text display as the human-machine dialogue interface control method.

[0003] At present, for the existing milling hammer with good wear resistance, through the cooperation of the driving rod, the first spring, the slider and the second spring in the buffer assembly, the mechanical pressure from the grinding machine can be relieved, effectively solving the problem that the excessive grinding of the bottom end of the milling hammer and the grinding bowl due to excessive pressure of the grinding machine accelerates the wear of the milling hammer; through the cooperation of the chute and the sphere, the grinding effect of the milling hammer is improved; through the cooperation of the limiting column, the limiting plate and the bolt in the connecting mechanism, the disassembly and assembly of the milling hammer are facilitated, so as to facilitate its cleaning and replacement.
