Abstract
A kind of four sword ball knives for graphite Machining of Curved Surface are the utility model is related to, are covered with a floor height pure diamond coating in the bit interface of graphite nodule knife, head is designed using big anterior angle, effectively reduces cutting resistance, make cutting more brisk；The utility model composite diamond coating, the extension of crackle is effectively reduced, improve the protection to matrix, extend cutter life.
Description
Technical field
It the utility model is related to a kind of milling cutter, specifically a kind of four sword ball knives for graphite Machining of Curved Surface.
Background technology
In die manufacture, some positions can not be machined directly to position with cutter, now need by electrode machining side
Formula, and it is graphite that the carrier of electrode is most of.Graphite on similar market at present, have two kinds it is relatively common, and electric conductivity is more
Good graphite is purer, and difficulty of processing improves therewith.At present it is similar comparatively, the graphite tool sharpening time of effect well
All without more than 15 hours, and most of graphite polished surface time can process more than 20 hours, so needing exploitation to cut
Cutting the life-span reaches more than 20 hours.
Utility model content
The purpose of this utility model is to provide a kind of four sword ball knives for graphite Machining of Curved Surface, in the knife of graphite nodule knife
Head surface is covered with a floor height pure diamond coating, and head is designed using big anterior angle, effectively reduces cutting resistance, make cutting more
It is brisk；The utility model composite diamond coating, the extension of crackle is effectively reduced, improve the protection to matrix, extend the cutter longevity
Life.
Following technical scheme is used to achieve the above object：
A kind of four sword ball knives for graphite Machining of Curved Surface, including cutter head and milling cutter shank, ball knife entire length are 75mm public
The positive and negative 0.2mm of difference, a diameter of 4mm tolerances are to upper deviation 0.006mm；Wherein the length of cutter head is the positive and negative 0.3mm of 10mm tolerances,
Cutter head is using helical structure, and spiral is dextrorotation, and helical angle is 35 degree, and cutter head end is spherical in shape, and the outer rim of cutter head sets four groups
Helical form blade, chip area is provided between the adjacent edge of knife head ball end；One layer of diamond is covered with bit interface to answer
Close coating.
Described blade cutting edge side and cutter head radial direction is in a certain angle, and the angle of angle is 5 to 7 degree.
The utility model body can be effectively increased matrix and Buddha's warrior attendant using the less raw material of the larger amount containing cobalt of granularity
Adhesion between stone coating；Big basil design, effectively reduces cutting resistance, makes cutting more brisk；Using high-purity Buddha's warrior attendant
The nano-diamond coating that stone is formed, coating surface is more smooth, and case hardness can reach more than 80GPa, unique compound painting
Layer, the extension of crackle is effectively reduced, improve the protection to matrix, extend cutter life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is lateral structure schematic diagram of the present utility model；
Fig. 3 is overlooking the structure diagram of the present utility model；
Fig. 4 be in the utility model Fig. 2 C-C to sectional view.
Embodiment
As Figure 1-4, a kind of four sword ball knives for graphite Machining of Curved Surface, including cutter head 2 and milling cutter shank 1, ball knife are whole
Body length is the positive and negative 0.2mm of 75mm tolerances, and a diameter of 4mm tolerances are to upper deviation 0.006mm；The length of wherein cutter head 2 is
The positive and negative 0.3mm of 10mm tolerances, cutter head 1 are using helical structure, and spiral is dextrorotation, and helical angle is 35 degree, and the end of cutter head 2 is in ball
Shape, the outer rim of cutter head 2 set four groups of helical form blades 3, chip area 5 are provided between knife head ball end adjacent edge 3；
The surface of cutter head 2 is covered with one layer of diamond composite coating；Described blade cutting edge side and cutter head radial direction is in a certain angle, folder
The angle at angle is 5 to 7 degree.
The utility model body can be effectively increased matrix and Buddha's warrior attendant using the less raw material of the larger amount containing cobalt of granularity
Adhesion between stone coating；It is that 5 to the 7 big basils spent design that blade cutting edge side is in a certain angle with cutter head radial direction,
Cutting resistance is effectively reduced, makes cutting more brisk；The nano-diamond coating formed using high-purity diamond, coating table
Face is more smooth, and case hardness can reach more than 80GPa, unique composite coating, effectively reduce the extension of crackle, improve to matrix
Protection, extend cutter life.
Claims (2)
