Problems solved by technology
If the outer circle is processed by turning, it is difficult to meet the surface accuracy requirements of slotting processing
At the same time, the cutting grooves of the guide wheels for multi-wire cutting machines have shallow depth, small intervals, and high precision requirements. In addition, the polyurethane material is soft, so it is difficult to guarantee the precision requirements
At the same time, turning the wire grooves one by one takes a long time and is inefficient. There are many uncontrollable and unknown factors in the processing process, especially tool wear and lateral extrusion during cutting.
When the tool is worn, the material cannot be cut quickly, resulting in roughness defects, and bumps appear on the surface of the groove; in multi-wire cutting, the bumps can cause wire jumps, resulting in uneven thickness of the wafer, and even silicon rods are scrapped
Side-to-side extrusion forces may deform adjacent raceways that have been machined

Description
technical field [0001] The invention relates to a one-time molding technology for guide wheel slotting of a multi-wire cutting machine, in particular to a silicon rod multi-wire cutting machine guide wheel slotting one-time forming combination machine tool and its application. Background technique [0002] Wire cutting technology has replaced internal circle cutting technology and has become the mainstream technology in the large-scale production of wafers. It has the advantages of high efficiency, small incision, and less human factors in product quality. The polyurethane material guide wheel is one of the key parts of wafer wire cutting, and its quality determines the cutting quality of wafers to a large extent. In order to ensure the uniformity of the thickness of the wafer, the cutting line must be evenly and stably distributed on the cutting guide wheel. Slots are made on the polyurethane guide wheels to ensure their stability. [0003] During the multi-wire cutting p...
