Abstract

The utility model relates to a special cutter for drilling silicon crystal bars. The utility model provides a special cutter for hole is drawn to silicon crystal stick, includes the cutter base body of cylinder, the one end of cutter lateral wall is equipped with circular shape cutter base, and the centre of a circle position of cutter base is equipped with the shaft hole, is equipped with a plurality of connecting holes on the cutter base and is the circumference equipartition around the shaft hole, the other end of cutter lateral wall be equipped with a plurality of bellied cutting edges, be equipped with clearance, its characterized in that between two adjacent cutting edges: the gap is arc-shaped, and the section of the cutting edge is arc-shaped. The utility model has the advantages that: due to the adoption of the arc-shaped cutting edges and the arc-shaped gaps, the cutting working area is enlarged, the cutting process tends to be stable, the problems of single crystal fragmentation and tool breakage caused by tool stress concentration are solved, the abrasion of the tool is reduced, and the production efficiency is improved.

Description

A kind of silicon crystal bar is drawn the hole dedicated tool
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.
