The rotatable blade comprises a blade body, wherein the blade body is defined by two end faces, at least three side faces and transitional face sets connected between the two adjacent side faces; each side face is connected between the two end faces; at least one transitional face set is crossed with one end face to form a secondary cutting edge, a first main cutting edge and a second main cutting edge connected in sequence; one side face connected with the transitional face set is crossed with the end faces to form a third main cutting edge connected with the second main cutting edge; in a reference plane parallel to the end face, a main deflection angle of the first main cutting edge relative to the secondary cutting edge is K1; a main deflection angle of the second main cutting edge relative to the secondary cutting edge is K2; and a main deflection angle of the third main cutting edge relative to the secondary cutting edge is K3, wherein K1 is less than K2, and K2 is less than K3. According to the position rotatable blade for milling processing, good blade edge intensity can be obtained by a small main deflection angle in a fine processing process, and a larger cutting range can be realized in a rough processing process.
Description
Technical field
The present invention relates to metal cutting process, particularly relate to position rotatable blade for milling processing.
Background technology
For same blade, the tool cutting edge angle K of cutter is larger, its cutting-in a
plarger, but its cutting edge strength can reduce.But tool cutting edge angle is less, although its cutting edge strength can be strengthened, cutting-in often reduces---this is usually conflict.And in the accurately machined field of milling, so-called " cutting-in " value is usually set at the scope being less than 0.5mm, tool cutting edge angle little within the scope of this has the higher cutting edge life-span.But the tool cutting edge angle of reduction cutter simply, in the occasion being applicable to large cutting-in, can not limit make blade to the scope of application of blade.
Chinese patent literature CN101096057A discloses a kind of milling cutting insert, the extended line of its main cutting edge and front cutting edge is 45° angle, although the structure at this tool nose position has done simple change, but do not produce with cutter tool cutting edge angle and cutting-in and contact, its main purpose makes blade processing CGI(contracting shape graphite cast iron) blank time can not produce burr, therefore, it receives many restrictions in blade shapes and parameter, and the scope of application is also restricted.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art, there is provided a kind of and can be obtained good blade cutting edge intensity by less tool cutting edge angle when fine finishining, the position rotatable blade for milling processing of larger cutting-in scope can be obtained again when roughing.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of position rotatable blade for milling processing, comprise blade body, described blade body is by two end faces, at least three sides, and the transition face group be connected between adjacent two sides surrounds, each side is connected between two end faces, the front cutting edge that at least one transition face group connects successively with the crossing formation of an end face, first main cutting edge and the second main cutting edge, the side connected with this transition face group is crossing with end face forms the 3rd main cutting edge connected with described second main cutting edge, in the datum plane being parallel to end face, described first main cutting edge is K1 relative to the tool cutting edge angle of front cutting edge, described second main cutting edge is K2 relative to the tool cutting edge angle of front cutting edge, described 3rd main cutting edge is K3 relative to the tool cutting edge angle of front cutting edge, K1 < K2 < K3.
Be provided with First Transition sword between described front cutting edge and the first main cutting edge, between described first main cutting edge and the second main cutting edge, be provided with the second transitional edges.
In the datum plane being parallel to end face, the extended line of described first main cutting edge and the extended line of the second main cutting edge intersect at F point, beeline between F point and front cutting edge is H1,0.5mm≤H1≤1mm, and 20 ° of < K1 < 40 °.
