Description
Technical field
The utility model relates to a kind of material being combined by two or more substances more particularly to a kind of green bodies, are applicable in
In the cutter (such as: but be not limited to PCD cutter and CBN cutter) of manufacture processing hard-cutting material, improve the cutting ability of cutter.
Background technique
Polycrystalline diamond (PCD) cutter and cubic boron nitride (CBN) cutter provide for the cutting problem of difficult-to-machine material
Solution.
Cubic boron nitride (CBN or PCBN) is a kind of synthetic material, and hardness is only second to diamond, is had good
High-temperature stability (when ferrous metal and superalloy materials are hardened in processing, can generate very high temperature).The CBN of different designs
Cutter be used to continuously or intermittently cut the ferrous metal that hardens and machining welding metal and composition metal.
PCD cutter is to be welded in PCD material on cutter hub to be made.Under normal circumstances, by PCD material in basis material together
Diamond particles are sintered using metal based binder at high temperature under high pressure and are produced.PCD point of a knife can be by putting
Electric machining or laser are cut, and are welded in hard alloy or steel matrix, then form PCD cutter by sharpening, this
Cutter is especially effective in High-speed machining non-ferrous metal (such as: aluminium) and high abrasion synthetic material and plastics.CD cutter is wide
It is general to be applied to milling non-ferrous metal, composite material, plastics and extremely unmanageable superalloy.
The PCD cutter of public offering or CBN cutter are paster structure in the market, and the main technique of manufacture is according to knife
Have the requirement of design, the blade base of specific shape is first cut from prefabricated PCD disk or prefabricated CBN disk (referring to Fig. 1)
Body (referring to fig. 2), is then fixed on cutter hub by way of freezing again, in the processing for carrying out blade by grinding, such as: opening
Sword.
These composite sheets can only be attached in plane (referring to Fig. 3), may not apply on spiral shape cutter, made of this
The cutting anterior angle of cutter is small not sharp enough.In this regard, designed in industry using cutting edge inclination, but anterior angle angle can only < 15 degree of (and spirals
Tool orthogonal rake is generally 30 or more), cause cutter rigidly bad；Or multistage sword is used to imitate helical angle, but manufacturing process
Extremely complex, cost is also high, and the diamond cutter of this kind of construction cannot achieve complete apex diamond blade.
For this purpose, Chinese utility model patent ZL201621488802.2 provides a kind of base for ultra-hard cutting tool manufacture
Material and its cutter, including axis body, connector and blade shape adult etc..Connector one end and one end of axis body connect, and outer diameter is less than
The outer diameter of axis body.Blade shape adult is used to be processed into the blade of cutter comprising through-hole, through-hole along blade shape adult axial direction and
At.Connector is arranged in through-hole.
But although the technology realizes the cutter manufacture with helical angle and complete hard material apex sword, significantly improve
Cutter apex sword processing service life and processing effect, but have in the fabrication process using welding technology, to realize to cutting edge
Form the fixation of body.But the welding procedure due to using cutter diameter direction, bonding area is not only fairly small, but also is adding
Mainly by shearing force in work, so that welding surface contact strength is quite weak, it is very easy to crack to reduce knife in welding surface
Have the service life, therefore this kind of cutter is also not used to the processing of high-toughness metal material substantially, also has the prior art by trying to increase
The method of big welding surface area acts on significantly small-diameter cutter to improve weld strength.
