The angle of wedge of piece is increased, and can effectively increase the deformation of chip, assists the discharge of chip, and expand heat dissipation area increases simultaneously
The intensity of cutting edge.
3. according to the processing conditions of cutter, the blade, 8 ° or so of anterior angle, relief angle is 7 ° or so, and cutting edge inclination is 0 °；Blade
Front is designed with butterfly protrusion, and the long bits that will be generated in process is contributed to crimp and assist smoothly discharge after fractureing, are carried
The cleaning of high processing environment.
4. the blade cut sword nearby has hemispherical projections, semispherical surface friction coefficient is small, helps to flow through herein
Chip discharge, reduce knife-bits contact area and alleviate friction of the chip to blade, while increase the effective heat dissipation area of blade.
5. being equipped with font protrusion in river before the blade, chip contact with before blade can be reduced, flowed through herein
Chip is acted on by additional bending moment, is easily crimped and is fractureed；The gap between the word protrusion of river contributes to air circulation simultaneously, plays
The effect of cooling；Liquid is contributed to store when using coolant, improve cooling efficiency.
6. the dust lead wall that the blade uses is W-shaped structure, the chip generated during roughing can be made in contact dust lead
It is acted on after wall by guiding moment of force so that the discharge of chip more smooth fractures and is more prone to, and reduces knife-bits and connects
Contacting surface is accumulated, and increases rate of heat dispation.
7. forming a chip pocket between the blade rake face and W-shaped dust lead wall, increasing heat radiation area reduces blade row
Consider pressure to be worth doing；Storage part coolant simultaneously, can take away the heat generated during processing, effectively solve the problems, such as cutting heat accumulation.
8. the insert bottom is designed with circular radiating slot, insert bottom is divided into two regions by it, and it is difficult to reduce installation
Degree, can be such that blade is more closely combined together with knife bar.In process, coolant can flow through groove, and in groove
Of short duration storage, while screw hole can be also flowed through, play the role of cooling to screw.
In conclusion this blade is suitable for heavy cutting Tutrning Process, diamond shaped profile can efficiently reduce cutting
Drag, wide seamed edge linear cutting edge can effectively improve blade strength.Butterfly protrusion and river font protrusion can effectively will be heavy
Long bits in turning process are crimped, while are designed with hemispherical projections and are reduced friction of the chip to blade.A variety of protrusions
Cooperation so that the turning insert has preferable performance, is suitble to the processing operating mode of heavy cutting.The structure of the blade is simple, is produced into
This is low, is suitble to use in the rough machined turning phase of heavy cutting.
