Sharp anterior angle design and S type Cutting Edge Designs, make cutting more brisk, machined surface quality is more preferable；Chip space is increased, makes iron
Bits have enough chip spaces, and the cutter hub gap of cutter is designed without windage, reduces what the vibrations of cutter in High-speed machining were brought
The abnormal damage of cutting edge, bit interface scribble superpower wearability and thermal insulation, substantially reduce coefficient of friction, make finished surface
Quality is higher.
To realize that above-mentioned mesh uses following technical scheme：
A kind of two general ball cutters of sword high rigidity, including handle of a knife and cutter head, its feature in：The overall length of milling cutter is
The positive and negative 0.2mm of 75mm tolerances, a diameter of 8mm tolerances are to upper deviation 0.006mm；Wherein the length of cutter head is that 12mm tolerances are upward
Deviation 0.3mm, described tool tip material use a diameter of 0.2-0.4 microns of crystalline particle and amount containing cobalt as the superfine super of 8-12%
Particulate tungsten carbide is made, and head peripheral is provided with the chip area and cutting edge of two right-handed spiral configurations, and dextrorotation angle is 30 degree, two chip removals
Formed with Liang Ge spines between groove, described cutting edge is provided with the edge of spine and chip area junction, cutting edge continuously prolong
Extend the center of cutter head end；The anterior angle of cutting edge is 2-6 degree, and relief angle is positive and negative 1 degree of 10 degree of tolerances.
Described cutter head includes straight cutting portion and the cavetto cutting portion of end.
Circular arc smooth structure between the side of cutting edge and adjacent chip area is not provided with spine so that straight cutting
The section in portion is S-shaped.
One layer of Wear-resistant heat insulation layer based on AlCrN containing 2-5%Si elements is also coated with described cutter head appearance.
The utility model ensures that cutter has good wearability concurrently using superfine ultra micron tungsten carbide and 8-12% amount containing cobalt
And impact resistance, the length and width of ball finishing tool tool bottom cutting edge is improved, makes cutter when tabular surface is cut, is obtained more preferable
Surface quality and processing life-span, the design of sharp anterior angle and S type Cutting Edge Designs, make cutting more brisk, machined surface quality is more
It is good；Chip space is increased, iron filings there are enough chip spaces, the cutter hub gap of cutter is designed without windage, reduces and add in high speed
The abnormal damage of cutting edge that the vibrations of cutter are brought in work, coating, containing 2-5%Si elements, there is cutter based on AlCrN
Superpower wearability and thermal insulation, coating surface have one layer of very thin lubricating layer, and coating coefficient of friction substantially reduces, and makes processing
Surface quality is higher.
