STEPLESS GRINDING AND POLISHING APPARATUS

The invention discloses a stepless grinding and polishing apparatus comprising a spindle and a revolution disk connected with the spindle's lower section. The revolution disk has a plurality of grinding head installation positions with stepless grinding heads arranged in each position. Each head comprises a grinding wheel fixing seat with a swing space, grinding wheel shafts, grinding block and spherical kinematic pairs. Each spherical kinematic pair is positioned in the corresponding space. A gap is provided between each pair and the peripheral wall of its space. The upper section of each shaft is elastically connected with the corresponding head fixing seat. When the grinding heads revolve, the grinding blocks universally swing freely. The apparatus is suitable for carrying out surface processing on architectural ceramics, stones and dalles. It has a profiling function when processing the surface, without crushing it, and excellent grinding and polishing effects with high working efficiency. Fig.1
