According to the compound multi-step milling cutter capable of carrying out simultaneous multi-dimensional operation, the processing precision is greatly improved, the processing operation is smoothly carried out, the production efficiency is improved, the quality control ability is improved, and the production cost is lowered.
Description
Technical field
The utility model relates to a kind of aperture knife tool, particularly a kind of compound many step milling cutters in metal processing.
Background technology
Automobile turbocharger produces for the inadequate natural endowment that makes up naturally aspirated engine.Its advantage is to have the advantages such as characteristic, reduction fuel consume and engine noise of improving automobile engine tail gas exhaust emission, the power that improves engine and moment of torsion, so, in the situation that greatly develop now energy-saving and emission-reduction and environmental protection, engine with supercharger has become the standard configuration of Hyundai Motor and engineering machinery.But the working environment of turbocharger is very severe, during the vital part bearing working, rotating speed, up to more than 150000 rev/mins, also producing high temperature, therefore has very high requirement to technology control and machining accuracy.Traditional slotting cutter, only can control a kind of specification, during hole milling, can only complete the single size operation, while processing another large-size operation, need to change the milling cutter of another larger special size, again process operation, while processing another reduced size operation, need to change the milling cutter of another less special size, again process operation, during the operation of chamfering size, also need the milling cutter of changing special angle to carry out secondary operation, need like this five processing, inefficiency, and processing and dimension control difficulty.
Summary of the invention
The utility model purpose is to provide the compound step milling cutter of the many sizes of a kind of operation simultaneously.
Implementation of the present utility model: a kind of compound many step milling cutters, it is comprised of cutting blade and shank.Described cutting edge is partly three grades: comprise the one-level cutting edge of front end, its diameter is greater than the secondary cutting edge that is arranged at one-level cutting edge root; Be provided with the one-level transitional edges between described one-level cutting edge and secondary cutting edge, the knife edge angular of one-level transitional edges is set to be 42 ° with tool axis.The external diameter of the external diameter root of described one-level cutting edge arranges three grades of cutting edges; Be provided with the secondary transitional edges between described one-level cutting edge and three grades of cutting edges, the knife edge angular of secondary transitional edges is set to be 50 ° with tool axis.Described one-level cutting edge keeps vertical with the secondary cutting edge with tool axis, and three grades of cutting edges are parallel with tool axis.
The utility model is controlled macropore diameter, the degree of depth and flatness by the one-level cutting edge, control the taper hole angle by being provided with transitional edges between one-level cutting edge and secondary cutting edge, control cone diameter, the degree of depth and flatness by being provided with transitional edges between secondary cutting edge and I and II cutting edge, by between described one-level cutting edge and three grades of cutting edges, being provided with transitional edges control hole bicker degree and depth of chamfering.Only need a hole milling operation process can complete above-mentioned processing request, machining accuracy is promoted greatly, and operating efficiency improves more than 500% than traditional diamond-making technique.Obtain good economic benefit.Guaranteed carrying out smoothly of processing operation, enhanced productivity, improved the quality control ability, reduced production costs.

Specific embodiments
Compound many step milling cutters are comprised of cutting blade and shank 6.Described cutting edge comprises the one-level cutting edge 1 of front end, is arranged at the secondary cutting edge 2 of one-level cutting edge root; Be provided with one-level transitional edges 4 between one-level, secondary cutting edge.The external diameter of the external diameter root of one-level cutting edge arranges three grades of cutting edges 3, between one-level, three grades of cutting edges, is provided with secondary transitional edges 5.One-level, secondary cutting edge are vertical with tool axis.
The diameter d 1(one-level cutting edge of one-level cutting edge 1 and tool axis maximum distance) be greater than diameter d 2(secondary cutting edge and the tool axis maximum distance of secondary cutting edge 2) be less than tri-grades of cutting edges of diameter d 3(and the tool axis maximum distance of three grades of cutting edges 3).d2：d1：d3=0.722:1:1.383。The knife edge angular of one-level transitional edges 4 is set to be 42 ° with tool axis, and the knife edge angular of transitional edges 5 is set to be 50 ° with tool axis.
Cutter is cylinder, and the central axis of cutter hub of take when composite milling cutter carries out Milling Process is rotated as rotating shaft.The cutter hub front end is the processing cutting portion, cutting portion moves axially, control macropore diameter, the degree of depth and flatness by the one-level cutting edge, control the taper hole angle by being provided with transitional edges between one-level cutting edge and secondary cutting edge, control cone diameter, the degree of depth and flatness by being provided with transitional edges between secondary cutting edge and I and II cutting edge, by between described one-level cutting edge and three grades of cutting edges, being provided with transitional edges control hole bicker degree and depth of chamfering.Only need a hole milling operation process can complete above-mentioned processing request, machining accuracy is promoted greatly, and operating efficiency improves more than 500% than traditional diamond-making technique.Obtain good economic benefit.
