Abstract
The invention discloses a super-hard material drill head, which comprises a drill body and a blade connected to the front end of the drill body, the blade material is polycrystalline diamond, or polycrystalline cubic boron nitride, or ceramic material. The blade can be installed by multiple methods. The PCD (polycrystalline diamond) or PCBN (polycrystalline cubic boron nitride) cutter, the ceramics drill head, and other non metal material cutter can be used for processing high hardness alloy cast iron (high Ni to Cr, high chromium, etc), ductile cast iron, gray cast iron (brake wheel, brake drum, etc), hardened steel, etc., the invention solves the processing problem that the material is hard to be processed in drilling and cutting field, the invention which also can be used for drilling and cutting the normal material can improve the cutting efficiency.
Description
Technical field
The present invention relates to a kind of drill bit, particularly a kind of drill bit of processing superhard material.
Background technology
Development along with material technology and manufacturing industry technology, various high performance new materials continue to bring out, require the machining drill bit to have more high rigidity, heat endurance, chemical inertness and appropriate toughness, brought great challenge for traditional alloy bit, also machining is more and more difficult.
Therefore be necessary to develop a kind of new drill bit, have more high rigidity, heat endurance, chemical inertness and appropriate toughness, can adapt to the needs of modern superhard material processing.
Summary of the invention
Technical problem to be solved by this invention is,, heat endurance imperfect deficiency not high enough at conventional drill hardness provides the drill bit of a kind of high rigidity, heat endurance, chemical inertness and appropriate toughness, is used to process superhard material.
In order to solve the problems of the technologies described above, the present invention adopts following technical proposal:
A kind of superhard material drilling bit is made of a drill body and the blade that is connected the drill body front end, and described blade is a polycrystalline diamond, or polycrystalline cubic boron nitride, or ceramic material.
Can adopt dual mode that blade is installed, one of them is, the front end fluting of drill body, and the built-in blade of groove, a tight lock screw passes the blade middle part blade tightly is locked on the drill bit, and a hold-down screw passes drill bit and withstands the blade rear portion.
Similar alternative arrangements is the front end fluting of drill body, welding one blade in the groove.
Useful technique effect of the present invention is, PCD (polycrystalline diamond), PCBN (polycrystalline cubic boron nitride) cutter and ceramic material drill bit and other nonmetallic materials cutters, can be used to process alloy cast iron (high nickel chromium triangle, the high ferrochrome of high rigidity ...), spheroidal graphite cast-iron, casting pig (brake disc, brake hoop ...), hardened steel etc., solve the difficult-to-machine material in drilling field, can solve in the common material drilling and cut efficiency.

The specific embodiment
Example 1
As depicted in figs. 1 and 2, a kind of superhard material drilling bit is made of a drill body 1 and the blade 2 that is connected drill body 1 front end, and described blade 2 is a polycrystalline diamond, or polycrystalline cubic boron nitride, or ceramic material.
In the present embodiment, the front end of drill body 1 fluting, the built-in blade of groove 2, one tight lock screws 11 pass blade 2 middle parts blade 2 tightly are locked on the drill bit, and a hold-down screw 12 passes the rear portion that drill bit withstands blade 2.
Example 2
As shown in Figure 3, a kind of superhard material drilling bit is made of a drill body 1 and the blade 2 that is connected drill body 1 front end, and described blade 2 is a polycrystalline diamond, or polycrystalline cubic boron nitride, or ceramic material.
In the present embodiment, drill body 1 front end fluting, welding one blade 2 in the groove.
