Abstract
The utility model relates to a CBN head end mill. The fleet angle at an end edge is o.8 degree; the CBN head end mill is provided with CBN tool bits, the end surfaces of which are distributed in a stagger way, and also has the characteristics that the rear angle of the end edge is 7 degrees* 0.9 mm, 20 degrees, the rear angle of a side edge is 7 degrees* 0.9, 20 degrees, and the rear angle of a tool nose is 7 degrees* 0.9, 20 degrees; and the CBN head end mill can meet the requirements of medium and high speed processing, high accuracy, high efficiency and long service life in a cast iron compressor with complex tracks.
Description
Technical field
The utility model relates to a kind of milling cutter.
Background technology
Modern scroll compressor is widely used in central air-conditioning, air conditioning for automobiles and domestic air conditioning, and the complex form face of high speed, precision, long-life, its cast iron compressor body of high efficiency milling is that conventional tool is incompetent.
The utility model content
The purpose of this utility model is to provide a kind of cubic boron nitride (CBN) sword unique construction slotting cutter, with the problem of conventional tool performance shortcoming in the processing that solves complicated track cast iron compressor.
A CBN of the present utility model slotting cutter is characterized in, end sword drift angle is 0.8 degree.End sword drift angle is that 0.8 degree can play the effect of smoothing, and makes the cutting abrasion of end sword and side edge reach balance and the relative cutter life that improves, and cutting force again can be less simultaneously.
A described CBN slotting cutter, its further characteristics are that it is that 68 degree, outside diameter are that 9.4mm and end diameter are the frustum of a cone hole of 4mm that the cutter end has tapering.This round platform taper hole can provide chip space for knife end portion, is convenient to cutter grinding simultaneously, does not lose cutter intensity.
A described CBN slotting cutter, its further characteristics are that end clearance angle is 7 degree * 0.9mm, 20 degree; The side edge relief angle is 7 degree * 0.9,20 degree; The relief angle of point of a knife is 7 degree * 0.9,20 degree.The milling cutter that possesses these characteristics can reduce cutting force and keep certain smoothing effect, can also guarantee cutter intensity and optimal wear resistance.
A described CBN slotting cutter, its further characteristics be, 10 CBN cutter heads arrange at interval according to the distance of center circle of 8mm and 8.01mm, and the axial end of 8mm distance of center circle cutter head exceeds 0.01mm than the axial end of the distance of center circle cutter head of 8.01mm.The milling cutter that possesses these characteristics can make being used alternatingly of corresponding in twos blade master sword and secondary sword keep permanent cutting and abrasion equilibration again simultaneously, can strengthen and improve the durability of cutter like this, and guarantee the surface quality of workpiece to be machined.
A described CBN slotting cutter, its further characteristics be, corner radius is 0.3mm, can guarantee cutting edge strength like this, and it is sharp not lose blade again.
Aforementioned purpose of the present utility model, characteristics and beneficial effect will illustrate with the specific embodiment in the back in conjunction with the accompanying drawings further.
Description of drawings
Fig. 1 is the front view of slotting cutter of the present utility model.
Fig. 2 is the left side view of slotting cutter shown in Figure 1.
The specific embodiment
As depicted in figs. 1 and 2, a CBN of the present utility model slotting cutter has following architectural feature:
End sword drift angle A1 is 0.8 degree;
It is that 68 degree, outside diameter Φ 1 are the frustum of a cone hole of 4mm for 9.4mm and end diameter Φ 2 that the cutter end has taper angles A 2;
End clearance angle is 7 degree * 0.9mm, 20 degree,
The side edge relief angle is 7 degree * 0.9,20 degree,
The relief angle of point of a knife is 7 degree * 0.9,20 degree,
The mark mode of aforementioned each relief angle shows that it has two relief angles, and for example end clearance angle is 7 degree * 0.9mm, and 20 degree show the relief angles that it has 7 degree and the relief angles of 20 degree, and the width of face with relief angles of 7 degree is 0.9mm; The mark of all the other relief angles can be made same understanding with reference to above stated specification;
10 CBN cutter heads are that 8.01mm and distance of center circle R2 are that the mode of 8mm is arranged at interval according to distance of center circle R1, and the axial end of 8mm distance of center circle cutter head exceeds 0.01mm than the axial end of the distance of center circle cutter head of 8.01mm;
Corner radius is that R is 0.3mm.
