Abstract
The utility model relates to a knife and particularly relates to a polycrystalline cubic boron nitride blade for milling processing. The polycrystalline cubic boron nitride blade comprises a knife body and a knife head welded on the knife body, wherein the knife head contains two first knife edges and two second knife edges, a circular arc is arranged at the joint of the first knife edges and the second knife edges, a rear angle alpha is arranged between the knife body and the direction of the horizontal line, alpha is not less than 5 degrees and not more than 11 degrees, a round hole is formed in the center of the knife head, and the round hole is communicated with a through hole of the knife body. The utility model provides the polycrystalline cubic boron nitride blade for the milling processing, which can reduce the production cost, realize the accurate positioning and fixation, and further reduce the impact and vibration phenomena.
Description
Technical field
The utility model relates to a kind of cutter, particularly relates to a kind of polycrystalline cubic boron nitride blade for Milling Process.
Background technology
Metal part processing be unable to do without cutter, particularly along with the improvement of development of science and technology and material, requirement to process tool is more and more higher, and the cutter that uses is to adopt polycrystalline cubic boron nitride (PCBN) cutter blade at present, is welded by poly-cubic boron nitride cutter head and carbide alloy cutter hub.
In the prior art, because blade is overall structure, waste material not only, and processing cost height, blade is in the process of cutting, owing to there is not the hole, loosening easily in the process of machining, the instability that is installed causes workpiece to be machined influenced by external force and is out of shape, and burr appears in workpiece to be machined surface easily, cause crudy poor, influence productivity effect, and if the blade overall structure, because cutter has higher intensity in working angles, can cause cutter tipping and cracked.
Summary of the invention
The utility model is above-mentioned in order to solve, and provides a kind of and can reduce production costs, accurate positioning and fixing, and reduced and impact and the polycrystalline cubic boron nitride blade for Milling Process of seismism.
The technical solution of the utility model is:
A kind of polycrystalline cubic boron nitride blade for Milling Process, comprise cutter hub and the cutter head that is welded on the cutter hub, described cutter head contains two first blades and two second blades, the junction of described first blade and second blade is provided with a circular arc, described cutter hub and horizontal line direction are provided with a relief angle α, and 5 °≤α≤11 °, the center of described cutter head is provided with a circular hole, and described circular hole is connected with the through hole of cutter hub.
The material of described first blade and second blade is polycrystalline cubic boron nitride, and the material of described cutter hub is carbide alloy.
The circular arc chamfering radius size of described first blade and the second blade junction is 1.6mm.
The Circularhole diameter size at described cutter head center is 7.5mm, and the diameter of through hole is 5.5mm on the cutter hub.
Useful good effect of the present utility model is:
1. the utility model is provided with circular hole in the center of cutter head, can make accurately location and fixing of cutter, and it is stable to be installed, and has avoided in process loosening easily phenomenon occurring, has eliminated because of the cutter workpiece to be machined surface that instability causes that is installed burr, ropy problem to occur.
2. cutter hub of the present utility model is provided with through hole, can accurately fix, and prevents that cutter hub from sliding in process, solves cutter hub and repeats the difficulty that is installed, and has improved crudy.
3. blade of the present utility model is connected and composed successively by first blade and second blade head and the tail, and the cutter head center also is provided with circular hole, not only saves material, and avoids causing cutter tipping and cracked problem greatly because of intensity in the process.
