Description

Technical Field

[0001] The utility model relates to the technical field of single crystal silicon rod machining, in particular to a double-slot cutting guide wheel. Background Art

[0002] Typically, the mechanical processing of single crystal silicon rods includes cutting, squaring, grinding and polishing, and packaging inspection. The cutting process uses a cutting machine to process long single crystal silicon rods into short single crystal silicon rods of fixed or non-fixed length. The oxygen and carbon content of the single crystal silicon rods need to be tested after the rods are sliced. The industry currently uses single-slot or double-slot cutting guide wheels matched with annular diamond wire saws for rod cutting and slicing.

[0003] A cutting guide wheel generally includes a guide wheel base and a rubber coating layer. The guide wheel base is generally made of aluminum alloy, stainless steel, etc., and the coating layer is made of rubber. The coating layer is fixed to the outer ring of the guide wheel base and then formed by cutting and grooving. At present, ordinary single-groove or double-groove cutting guide wheels have a coating layer fixed to the outer ring of the guide wheel base, and the double grooves are of the same height. During use, the circular diamond wires frequently interfere with each other, causing wire breakage and coating damage, which leads to increased costs for the circular wire and cutting guide wheels and reduced production efficiency. Cutting guide wheels are vulnerable components in the field of single-crystal silicon rod wire cutting. In addition, the coating layer width of ordinary cutting guide wheels is about 9mm, and the coating layer cost is relatively high. The waste gas and waste chips generated during the coating process are likely to cause environmental pollution, which is not conducive to environmental protection. Utility Model Content
