Abstract

The utility model relates to a six-edge milling cutter. The milling cutter comprises a bar and a bit, wherein the bit is provided with six helical side cutting edges and six corresponding end edges; the helical angles alpha of the side cutting edges are 45-50 degrees; helical chip grooves are formed between the side cutting edges; first clearance angles of the end edges are 7 degrees; second clearance angles of the end edges are 16 degrees; rake angles of the end edges are 8 degrees; an aluminium-titanium nitride coating is arranged on the surface of the bit. After the structure is adopted, when a machined face of a workpiece is machined, the end edges and the side cutting edges are used for machining the workpiece, metal chips generated by machining are smoothly removed from the chip grooves with helical angles of 45-50 degrees and can not be jammed between the machined face and the cutter, thus ensuring the machining precision and quality of the machined workpiece and simultaneously prolonging the service life of the cutter.

Description

Six blade milling cutters
Technical field
The utility model relates to a kind of milling cutter, particularly a kind of six blade milling cutters.
Background technology
In machining, need to adopt milling cutter to mill out end face, inclined-plane, groove and step surface to different workpiece.Existing slotting cutter is when carrying out milling to workpiece, and the metal fillings that mills out is difficult for discharging, easily get lodged in cutter and machined surface near, affect machining accuracy and the quality of workpiece, also can produce certain wearing and tearing to cutter, the service life of reduction cutter simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of convenient six blade milling cutters of discharging metal fillings and can guarantee precision and the quality of processing work.
The technical scheme that realizes the utility model object is as follows:
A kind of six blade milling cutters, comprise knife bar and cutter head, six spiral helicine side cutting edges and six corresponding end swords are set on described cutter head, the pitch angle alpha will of described side cutting edge is between 45 °-50 °, between described side cutting edge, be provided with helical form chip area, end sword first relief angle of described end sword is 7 °, and end sword the second relief angle is 16 °, and end angle of cutting edge is 8 °.
Described pitch angle alpha will is 45 ° or 47 ° or 49 ° or 50 °.
The diameter of described knife bar is between 6-25mm.
The axial length L 1 of described cutter head is between 16-50mm.
The axial overall length L of described milling cutter is between 60-100mm.
Described cutter head surface arranges TiAlN coating.
Adopt after said structure, the utility model adds man-hour to workpiece machined surface, and end sword and side cutting edge are processed workpiece, and the metal fillings of processing is 45 ° from helical angle -in the chip area of 50 °, discharge smoothly, there will not be metal fillings to get lodged between machined surface and cutter, guarantee machining accuracy and the quality of workpiece to be machined, also extended the service life of cutter simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
