Abstract
The invention relates to a double-edged milling cutter. The cutter comprises a cutter rod and a cutter head, the cutter head is provided with six side cutting edges and six corresponding end edges, the side cutting edges are spiral in shape, the spiral angle of each of the side cutting edges is 45-50DEG, a spiral chip discharging slot is arranged between adjacent two side cutting edges, and the first clearance angle, the second clearance angle and the anterior angle of each of the end edges are 7DEG, 16DEG and 8DEG respectively. The surface of the cutter head is provided with a titanium aluminum nitride coating. When the cutter adopting the above structure is used to process the processed surface of a workpiece, the end edges and the side cutting edges are used to process the work piece, and processing metal chips are smoothly discharged from the chip discharging slots with the spiral angle of 45-50DEG, so the blocking of metal chips between the processed surface and the cutter is prevented the processing precision and the quality of the processed workpiece are guaranteed, and the service life of the cutter is prolonged.
Description
Technical field
The present invention 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 milled out not easily is discharged, and easily gets lodged near cutter and machined surface, affects machining accuracy and the quality of workpiece, also can produce certain wearing and tearing to cutter simultaneously, reduces cutting-tool's used life.
Summary of the invention
The object of this invention is to provide a kind of convenient discharge metal fillings and the precision of processing work and six blade milling cutters of quality can be ensured.
The technical scheme realizing the object of the invention is as follows:
A kind of six blade milling cutters, comprise knife bar and cutter head, described cutter head is arranged six end swords of six spiral helicine side cutting edges and correspondence, the pitch angle alpha will of described side cutting edge is between 45 °-50 °, helical form chip area is provided with between the cutting edge of described side, end sword first relief angle of described end sword is 7 °, and end sword 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 bit interface arranges TiAlN coating.
After adopting said structure, the present invention adds man-hour to workpiece machined surface, end sword and side cutting edge are processed workpiece, the metal fillings of processing is discharge smoothly the chip area of 45 °-50 ° from helical angle, metal fillings is there will not be to get lodged between machined surface and cutter, ensure machining accuracy and the quality of workpiece to be machined, also extend cutting-tool's used life simultaneously.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of end sword of the present invention.
