Problems solved by technology

[0002] The inner circle slicer is a special equipment used to cut brittle and hard metal or non-metallic materials, such as monocrystalline silicon, strong magnets, etc. Most of the inner circle slicers used are single-blade slicers. The material is hard, the speed is high, the machining accuracy is high, and the processing equipment and environmental conditions are high. The processing environment temperature and air quality have a great influence on the accuracy of the processed workpiece, and the efficiency of the single-blade inner circle slicer is low. The unit The area processing cost remains high, and the cutting efficiency of the multi-blade outer circle slicer is high, but the machining accuracy is difficult to meet the technical requirements. CN2084870U proposes a fixed structure for the grinding head of the inner circle slicer. The improved knife fixation structure can cut large sizes Silicon single wafer, which improves the quality of slicing, but its single-edge structure still hinders the improvement of cutting production efficiency

Embodiment Construction

[0017] As shown in Fig. 2, Fig. 3 and Fig. 5, the cutter assembly of the multi-knife internal circle slicer is fitted with an intermediate ring 6 on the outer surface of the cutter disc 1. The large end surface of one end of the intermediate ring is covered outside, and the other end is a small end surface. Be enclosed within the inside of outer left knife holder ring 7. Between the cutter head 1 and the middle ring 6, an inner left cutter ring 3 and an inner right cutter ring 4 are set to clamp and fasten the first inner circle slicer, and the blade tension is adjusted by the inner cutter ring screw 5 And fasten it with the cutter head. After loading onto the middle ring 6, the middle ring 6 is fixed with the dress cutter head by the fastening screw 2 of the middle ring of the cutter head. The second inner circle slicing knife is installed between the outer left clamping ring 7 and the outer right clamping ring 8 and is tensioned by the small end face of the middle ring 6, a...
