Abstract
The utility model relates to a thin-wall bortz bit (please see the attachment picture), comprising a tool bit 1, a body 2 and a head-connecting 3. The tool bit 1 is integrated or separated type, the tool bit 1 is formed by even mixing of bortz granule and metal powder and has initial cold-press molding with the body 2 and final sintering molding. Outer side at top part of the tool bit 1 is chamfering or rounding off; a plurality of splines are arranged at top part. The utility model has the advantages of solving failures such as poor performance of centering, poor self-sharpening and difficulty of scraps removing for current thin-wall bortz bit, providing a bortz bit with good centering performance, good self-sharpening and easy scraps removing, especially suitable for non-water drilling, low cost and short production circle and can be used in hole-drilling processing for each crisp material.
Description
Technical field
The utility model relates to a kind of thin faced bit, particularly a kind of cold-rolled sintered formula thin faced bit, and the boring that can be applicable to various crisp and hard materials is processed.
Background technology
In the prior art, the boring machining tool of crisp hard material mostly adopts flat flank of tooth thin faced bit, and there is the centering poor performance in this drill bit, and self-sharpening can be poor, deficiencies such as chip removal difficulty.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, and a kind of centering excellent performance is provided, and self-sharpening can be good, chip removal is easy, is particularly suitable for anhydrous creeping into, and production cost is low, diamond bit with short production cycle can be used for the boring processing of various crisp and hard materials.
The technical solution of the utility model is: comprise cutter head 1, steel body 2, adaper 3.Cutter head 1 is a monoblock type or split type, and cutter head 1 mixes the back with steel body 2 preliminary cold moudling, sinter moldings then by diamond particles and metal dust.Cutter head 1 top outside chamfering or rounding, the top has some teeth groove.
The beneficial effects of the utility model are: solved existing thin-walled diamond bit centering poor performance, self-sharpening can be poor, defectives such as chip removal difficulty.A kind of centering excellent performance is provided, and self-sharpening can be good, and chip removal is easy, is particularly suitable for anhydrous creeping into, and production cost is low, and diamond bit with short production cycle can be used for the boring processing of various crisp and hard materials.
Description of drawings
Fig. 1 thin faced bit
The specific embodiment
Figure of description is an enforcement optimal way of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in the figure: thin faced bit comprises cutter head 1, steel body 2, adaper 3.Cutter head 1 is a monoblock type or split type, and cutter head 1 mixes the back with steel body 2 preliminary cold moudling, sinter moldings then by diamond particles and metal dust.Cutter head 1 top outside chamfering or rounding, the top has some teeth groove.Because the utility model adopts integral sintered formula cutter head, technology is simple, and equipment investment is few, and is with short production cycle, thereby cost is low, good in economic efficiency.During drill bit work, cutter head is that circumference contacts with workpiece, the centering excellent performance; The inclined-plane of head top surface meets drill bit actual wear rule, thereby the cutter head abrasion evenly, and chip removal is smooth and easy.In a word, the utility model has solved existing thin faced bit centering poor performance, and self-sharpening can be poor, defectives such as chip removal difficulty.A kind of centering excellent performance is provided, and self-sharpening can be good, and chip removal is easy, is particularly suitable for anhydrous creeping into, and production cost is low, and diamond bit with short production cycle can be used for the boring processing of various crisp and hard materials.
