Abstract
The utility model relates to a special cutting tool for digging holes in silicon crystal rods, which comprises a tubular cutting tool substrate, wherein one end of the cutting tool side wall is provided with a round cutting tool base, the circle center part of the cutting tool base is provided with a shaft hole, a plurality of connecting holes are arranged in the cutting tool base and are uniformly distributed around the shaft hole in a circumferential type, the other end of the cutting tool side wall is provided with a plurality of projected cutting edges, and a gap is arranged between each two adjacent cutting edges. The special cutting tool is characterized in that the gaps are in a circular arc shape, and the cross section of the cutting edges is in the circular arc shape. The special cutting tool has the beneficial effects that because of the adoption of the circular arc-shaped cutting edges and the gaps, the cutting work area is enlarged, the cutting process is stable, the problems of single crystal crushing and edge breakage while cutting caused by cutting tool stress concentration are solved, in addition, the abrasion of the cutting tool is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of silicon crystal bar machining equipment, and particularly a kind of silicon crystal bar is drawn the hole dedicated tool.
Background technology
At present, along with the continuous increase of diameter of czochralski silicon monocrystalline, its derived product type is on the increase, and the processing method of silicon single crystal has been pulled out new requirement.The known spot facing cutter of drawing all is to copy water to bore structure to make, and edge of a knife cross section is a rectangle, and promptly the edge of a knife is a flat-bottom structure, utilizes the cutter rotation that silicon single crystal is cut.This cutter structure meets the conventional design thinking; Processing technology is simple, still, in cutting process, has problem of stress concentration at edge of a knife right angle; Make monocrystalline produce cracked easily and when going out cutter suddenly, produce and collapse the limit; This structure only end face plane abrasive material participation cutting in process in addition, tool wear is big, and efficient is lower.
The utility model content
The purpose of the utility model provides a kind of the solution because cutter stress concentrates the monocrystalline that is caused cracked and go out cutter and collapse the limit problem, and can reduce tool wear, and the silicon crystal bar of enhancing productivity is drawn the hole dedicated tool.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of silicon crystal bar is drawn the hole dedicated tool, comprises columnar cutter sidewall, and an end of cutter sidewall is provided with circular cutter base; The position, the center of circle of cutter base is provided with axis hole; Cutter base be provided with a plurality of connecting holes be circumferential be distributed on axis hole around, the other end of described cutter sidewall is provided with the cutting edge of a plurality of convexities, is provided with the gap between two adjacent cutting edges; Described gap is a circular arc, and the section of described cutting edge is a circular arc.
The thickness of described cutting edge is greater than the thickness of cutter sidewall.
Described cutting edge surface is covered with diamond particles.
The beneficial effect of the utility model is: owing to adopt the cutting edge and the gap of circular arc; Strengthened the work area of cutting; The working angles trend steadily; Overcome because cutter stress concentrates the monocrystalline that is caused cracked and go out cutter and collapse the limit problem, and reduced the wearing and tearing of cutter, improved production efficiency.
Description of drawings
Fig. 1 is the generalized section of the utility model.
Fig. 2 is the enlarged diagram at A position among Fig. 1.
Fig. 3 is the enlarged diagram at B position among Fig. 1.
Among the figure, 1, cutter base, 2, the cutter sidewall, 3, cutting edge, 4, axis hole, 5, the gap, 6, connecting hole.
The specific embodiment
The utility model is that a kind of silicon crystal bar is drawn the hole dedicated tool; Owing to adopt the cutting edge and the gap of circular arc; Strengthened the work area of cutting, the working angles trend has steadily overcome because cutter stress concentrates the monocrystalline that is caused cracked and go out cutter and collapse the limit problem; And reduced the wearing and tearing of cutter, improved production efficiency.
Below in conjunction with accompanying drawing the utility model is further specified:
Specific embodiment, like Fig. 1, Fig. 2, shown in Figure 3, a kind of silicon crystal bar is drawn the hole dedicated tool; Comprise columnar cutter sidewall 2, an end of cutter sidewall 2 is provided with circular cutter base 1, and the rotating shaft that the position, the center of circle of cutter base 1 is provided with axis hole 4 and lathe links; Around axis hole 4, be circumferential and be evenly distributed with 4 connecting holes 6, pass connecting hole 6 with bolt the utility model is fixed on the lathe, the rotating shaft of lathe will drive the utility model and rotate together; The other end of cutter sidewall 2 is provided with the cutting edge 3 that a plurality of raised surface are covered with diamond particles; The section of cutting edge 3 is a circular arc, and the thickness of cutting edge 3 has increased the work area of cutting like this greater than the thickness of cutter sidewall 2; Be provided with the gap 5 of circular arc between two adjacent cutting edges 3, overcome the problem that stress is concentrated.Owing to adopt the cutting edge and the gap of circular arc, strengthened the work area of cutting, the working angles trend has steadily overcome because cutter stress concentrates the monocrystalline that is caused cracked and go out cutter and collapse the limit problem, and has reduced the wearing and tearing of cutter, has improved production efficiency.
