Description

technical field [0001] The invention relates to a silicon rod processing machine, in particular to a square rod polishing and grinding processing center capable of finishing crystal ingots. Background technique [0002] With the rapid development of the electronics industry, especially the development of the photovoltaic industry, the demand for silicon electronic materials is increasing, and the corresponding industry is growing rapidly. Therefore, the requirements for processing equipment for silicon electronic materials are also getting higher and higher, especially for The production efficiency and processing precision of the equipment have higher requirements. However, in the current monocrystalline silicon or polycrystalline silicon square bar processing process, in order to process the silicon ingot into a square bar of the specifications required by the downstream industry, it is necessary to use a crystal surface grinder to grind four planes, and use an outer cylind...
