Description
Technical field
The present invention relates to metal cutting process field, more particularly, to a kind of rotary cutting tool with double-layer cutting edges.
Background technology
Rotary cutting tool, in order to improve working (machining) efficiency, is generally equipped with the cutting tip of multi-quantity as far as possible, so that for revolving
Turn cutting tool and cutting edge as much as possible is set, the purpose of do so is to be at utmost to reduce cutting edge under identical feeding
Cutting force on piece especially tangential force.However, rotary cutting tool is when using, in order to ensure that chip smoothly discharges and keep away
Exempt from and cutter hub interfere, in the circumferential, need have chip space to be generally chip pocket in the top surface areas of milling cutting insert, simultaneously for
Ensure that blade installation slot can be that cutting tip provides enough cutting bearing capacitys and impact resistance, need in cutter groove
Bottom retains relatively thicker material, therefore, need to take into account the demand of chip pocket and cutter groove during design cutter, in rotary cutting sharpener
Sufficiently large chip pocket should be had to carry out chip removal in the circumference of tool, have sufficiently thick entity to carry out proof strength again, this necessarily just leads
The quantity having caused cutting tip is restricted.As can be seen here, in the prior art rotary cutting tool in order to improve working (machining) efficiency
Need to arrange cutting tip as much as possible, and in order to ensure that chip removal and tool strength need setting cutting edge as few as possible
Piece, this contradiction has become the principal element limiting rotary cutting tool cutting ability.
In order to reduce the restriction to rotary cutting tool for the above-mentioned contradiction, occur in that there is double-layer cutting edges structure at present
Cutting tip load rotary cutting tool technical scheme, the cutting tip in a cutter groove can successively be cut twice from
And realize increasing the purpose of cutting edge number, this kind of structure largely improves effective sword that rotary cutting tool participates in cutting
Number, but, in order to ensure the edge strength first participating in the cutting tip of double-layer cutting edges structure cutting, this cutting edge needs to be had
There is rear knife face full enough, this participates in the cutting edge corresponding channel space very little cut after making, groove design is also subject to
Very big restriction, corresponding chip breaking, with to hold bits ability also very poor, therefore, is entered to the cutting tip of this double-layer cutting edges structure
During row design, the rear cutting edge participating in cutting need to be set smaller than first participating in respect to the radius of clean-up of rotary cutting central shaft
The cutting edge of cutting is with respect to the radius of clean-up of rotary cutting central shaft, thus the cutting edge participating in after reducing cutting corresponding is cut
Cut the amount of feeding, so that its work in-process produces more frangibility, is more easy to the chip of discharge.From the point of view of changing an angle, due to rear participation
The cutting edge corresponding cutting feed amount very little of cutting, its cutting contribution less, along with this, there are double-layer cutting edges
Cutting blade structure is complicated, precision controlling is difficult, manufacturing cost is very high, and after having one layer of cutting edge abrasion in two-layer cutting edge
It is necessary for changing whole blade, use cost is very high it is seen that its cost performance is actually very low.
Content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, provide stock-removing efficiency high, easily manufactured, section
The about smooth rotary cutting tool with double-layer cutting edges of cost and chip removal.
