The connection between the polishing disc and the stone polishing machine can be divided into the following three types: bolt tray: suitable for polishing machines with bolt joints. Nut plate: Suitable for polishing machines with nut joints. Suction cup: Suitable for polishing machines with suction cups. That is, the head of the polishing machine is fixed with a rigid plastic polyester chassis (also called a tray), and the working surface of the chassis can be attached to an object with a nylon easy-to-stick plane, so that various suction cups can be selected according to the needs. Polishing plate, just put this polishing plate on the chassis, it is very convenient to use.
The key to the operation of the polisher is to try to get the maximum polishing rate in order to remove the damage layer from the polishing as quickly as possible. At the same time, the polishing damage layer will not affect the final observed tissue, ie, it will not cause false tissue. The former requires the use of coarser abrasives to ensure a larger polishing rate to remove the polished damage layer, but the polished damage layer is also deeper; the latter requires the use of the finest material to make the polished damage layer shallower, but polished The rate is low.
The speed of the turntable can be appropriately increased during fine polishing, and the polishing time is preferably to throw away the damage layer of the rough throw. After fine polishing, the polished surface is as bright as a mirror. No scratches can be seen under the bright field conditions of the microscope, but the wear marks are still visible under phase contrast lighting conditions. The polishing quality of the polishing machine seriously affects the structure of the sample, which has gradually attracted the attention of relevant experts. At home and abroad, a lot of research work has been done on the performance of the polishing machine. Many new models and a new generation of polishing equipment have been developed, which have been developed into various semi-automatic and fully automatic polishing machines from the original manual operation.
