The machine is a silicon chip cutting machine with high machining capability, high machining accuracy and high material utilization rate.

Description

technical field [0001] The invention relates to the field of plate cutting machinery, in particular to a constant tension control numerically controlled multi-wire square cutting machine without a pressure sensor. Background technique [0002] Wafer cutting is the upstream key technology for the production of crystalline silicon wafers, the leading material in the solar photovoltaic industry. The quality and scale of cutting directly affect the subsequent production of the entire industrial chain. With the rapid development of my country's photovoltaic power generation and information industry, especially the microelectronics industry, the demand for silicon wafers is increasing, the diameter of processed workpieces is increasing, and the technical requirements for processed products are also increasing. At present, silicon wafer slicing mostly adopts inner circle cutting and multi-wire cutting with free abrasive grains. Internal cutting is a traditional processing method, ...
