Feed movement, whereby the surface of the workpiece 1 is ground. Although the above-mentioned grinding machine 10 has the function of grinding, the surface roughness of the workpiece 1 depends on the size of the particles of the grinding wheel 133. In general grinding operations, it is divided into rough grinding and fine grinding. The grinding wheel used for coarse grinding has coarser grains and large removal amount but the surface roughness of the workpiece is coarser. The grinding wheel used for fine grinding has finer particles and smaller grinding amount but the surface roughness of the workpiece is finer. The grinding wheel mechanism 13 of the general grinding machine 10 can only install one set of grinding wheels 133 at a time. When the user wants to perform rough grinding and fine grinding on the workpiece 1, he must manually replace different grinding wheels 133 in good time. trouble.

Referring to Fig. 3, another kind of existing grinding machine 20 also has a machine platform 21, a group of workpiece holders 22 arranged at the place ahead of the machine platform 21, and a group of grinding wheel mechanisms 23 arranged at the place behind the machine platform 21, the workpiece holder Seat 22 has a chuck 221 and a tailstock 222, which can clamp and fix a workpiece 2. The emery wheel 233 of revolving seat 232, referring to Fig. 4, the emery wheel 233 of multiple different forms and particle thickness can be installed at this revolving seat 232 two sides places, when wherein one emery wheel 233 finishes a job to workpiece 2, The rotating base 232 can be rotated to allow another grinding wheel 233 to continue to grind the workpiece 2, thereby solving the problem of inconvenient use of the grinding wheel. However, the above-mentioned grinding machine 20 is used internally because all grinding wheels 233 are arranged on the same rotating base 232. It is the same rotating main shaft (not shown in the figure). When grinding for a long time, factors such as machine vibration, part wear and temperature rise of the grinding wheel mechanism 23 will continue to occur, which seriously affects the effect of all grinding wheels 233 on the workpiece 2. The grinding accuracy leads to a reduction in the grinding quality of the workpiece 2.
