Abstract
The utility model discloses a kind of durable cutting tool for machining; comprise the cutter hub that one-body molded or split connects and composes; described cutter hub is divided into clamping part and cutting portion; one deck diamond grain or CBN layer of sand is fixed with in the anterior face of described cutting portion; described diamond layer of sand or CBN layer of sand have the diamond sand grains of multiple corner angle by several or CNB sand grains is formed, and the multiple corner angle be fixed on several sand grains of described cutting portion anterior face constitute multiple cutting edges that several have different cutting angle.Diamond is the material that current known hardness is the highest, and adopting the structure of diamond grain coating to solve wolfram steel all the time cannot the efficient and problem of high accuracy processing.CBN (cubic boron nitride) its structure not carbon elements can not be had an effect with carbon containing metal, hardness is only second to diamond, CBN sand coating weares and teares when then solving more than traditional cutting mill processing HRC60 degree material the problem causing precision not good fast, and significantly improves cutting-tool's used life.
Description
Technical field
The utility model relates to machine cutting tool, is specifically related to a kind of durable cutting tool for machining.
Background technology
In the prior art, the cutter normally adopting wolfram steel to make for mach cutter goes workhardness lower than the workpiece of wolfram steel; When wolfram steel will be processed, prior art does not have cutter effectively can cut wolfram steel and only otherwise can process wolfram steel at present, such as line cuts processing, but its machining shape is restricted, or process with spark machine electric discharge, but spark machine long processing time, product face rugosity is not good, the above technical problem now wolfram steel processing being badly in need of to want to improve.
Material in the past between large multi-processing HRC52 ~ 58 of wolfram steel milling cutter degree, but along with the lifting of material, the hardness of such as Powder High-speed Steels can reach more than HRC64 degree, wolfram steel milling cutter is when cutting the material that so height is hard, can wear and tear fast, cause the problems such as cutter life is not good, and Product Precision is bad, need the improvement making further cutting-tool engineering.
Utility model content
The purpose of this utility model is: for the above-mentioned defect of prior art, a kind of durable cutting tool for machining is provided, solves the problem that cannot directly process of wolfram steel and process other high rigidity steel quick abrasion speed and cause the problem that cutter life is not good and Product Precision is bad.
A kind of durable cutting tool for machining is provided; comprise the cutter hub that one-body molded or split connects and composes; described cutter hub is divided into clamping part and cutting portion; one deck diamond grain or CBN layer of sand is fixed with in the anterior face of described cutting portion; described diamond layer of sand or CBN layer of sand have the diamond sand grains of multiple corner angle by several or CBN sand grains is formed, be fixed on several diamond sand grains of described cutting portion anterior face or CBN sand grains form on multiple corner angle constitute multiple cutting edges that several have different cutting angle.
Above-mentioned in the durable cutting tool of machining, described cutting tool is a kind of aperture knife tool, the cutting portion of described aperture knife tool has out cuts groove, one deck diamond layer of sand is fixed with in the anterior face of described milling cutter cutting portion, the diamond sand grains that described diamond layer of sand has multiple corner angle by several is formed, and the multiple corner angle be fixed on several diamond sand grains of described cutting portion anterior face constitute multiple cutting edges that several have different cutting angle.
Above-mentioned in the durable cutting tool of machining, described cutting tool is a kind of Milling Process cutter, the anterior periphery of described Milling Process cutter is fixed with one deck diamond layer of sand, the diamond sand grains that described diamond layer of sand has multiple corner angle by several is formed, and the multiple corner angle be fixed on several diamond sand grains of described cutting portion anterior face constitute multiple cutting edges that several have different cutting angle.
Above-mentioned in the durable cutting tool of machining, described fixed diamonds layer of sand or CBN layer of sand can adopt one of following manner to fix: spraying, plating, bonding, sintering.
The utility model tool has the following advantages: be fixed on several the tiny diamond grains on Tool in Cutting head or CBN sand, because the hardness of diamond grain or CBN sand is very high, wear-resistant, therefore the material of wolfram steel or high rigidity can be processed, extend cutter life raising machining accuracy and shorten process time, fall for production cost, its multiple corner angle exposed constitute multiple cutting edges that several have different cutting angle, cutter operationally, that multiple cutting edge participates in machining simultaneously, it also can reduce the roughness of surface of the work in working angles, improve crudy, CBN (cubic boron nitride) its structure not carbon elements can not be had an effect with carbon containing metal, hardness is only second to diamond, CBN sand coating weares and teares when then solving more than traditional cutting mill processing HRC60 degree material the problem causing precision not good fast, and significantly improve cutting-tool's used life.Comprehensive above characteristic, both all significantly can reduce production cost, and constitute with multiple corner angle that it exposes multiple cutting edges that several have different cutting angle, and operationally multiple cutting edge participates in machining simultaneously, significantly reduce the roughness of surface of the work, improve product processing quality.To sum up advantage is an innovation to Machining Technology for Cutting from now on and improvement.Be particularly suitable for the workpiece of processing high-hardness material, as the high rigidity steel after wolfram steel or heat treatment.
