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 impact on the accuracy of the workpiece. However, the efficiency of the single-blade inner circle slicer is low. 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 blade structure still hinders the improvement of cutting production efficiency

Embodiment Construction

[0012] Knife loader assembly of multi-knife inner circle slicer figure 2 , image 3 with Figure 5 As shown, an intermediate ring 6 is set in the outer sleeve of the cutter head 1, the large end face of one end of this intermediate ring is sleeved outside, and the other end is the inside of the outer left clamping knife ring 7 for the small end face. Between the cutterhead 1 and the middle ring 6, the inner left cutter ring 3 and the inner right cutter ring 4 for clamping and fastening the first inner circular slicer 10 are set, and the blade is adjusted by the cutterhead screw 5 of the inner cutter ring. Tension and fasten 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 11 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 in...
