The testing machine is simple in structure, wire saw constant-force tensioning and workpiece constant-force feeding saw cutting machining are achieved, reliability is high, the testing machine can be used for evaluating the saw cutting machining efficiency, the saw cutting machined surface quality, the wire saw surface grinding particle disengaging rate, wire saw abrasion and other saw cutting machining performance of a diamond wire saw, and saw cutting machining technology parameters and the like of the diamond wire saw are determined and optimized.

Description

technical field [0001] The invention relates to a testing machine for evaluating the sawing processing performance of a diamond wire saw, and belongs to the technical field of diamond wire saw sawing processing. Background technique [0002] Diamond wire saw refers to a cutting tool made by consolidating high hardness and high wear resistance diamond abrasive grains on the steel wire substrate by a certain method. According to the different methods of consolidating abrasive grains on the substrate, Diamond wire saws are divided into resin bonded diamond wire saws, electroplated diamond wire saws, etc. Diamond wire saw has the advantages of high sawing efficiency, good sawing surface quality, small kerf loss, less environmental pollution, and can realize multi-piece sawing of large-diameter workpieces. It has been widely used in monocrystalline silicon, Sawing processing of hard and brittle materials such as polysilicon, sapphire, and single crystal silicon carbide. [0003...

AI Technical Summary

Problems solved by technology

[0003] At present, the performance detection index of diamond wire saw is not perfect, which leads to insufficient correlation between detection index and sawing processing performance, and diamond wire saw with good performance detection index cannot meet the requirements of sawing processing

The processing parameters during the sawing process of the diamond wire saw do not match its performance, and it is difficult to ensure efficient and precise sawing process

[0004] The existing enterprise-level slicing machine has complex structure and large size, and the cost of sawing processing test is very high. There is an urgent need to evaluate the sawing performance of diamond wire saw through a simple and general sawing test machine.
