Abstract
The utility model belongs to cutting tool field, be specifically related to a kind of integral sintered PcBN wiper insert, comprise blade body, described blade body is wiper insert, blade body is processed with chamfered edge, and the chamfered edge angle of wiper edges part is less than the chamfered edge angle at tool arc place.Relative to prior art, the utility model adopts the chamfered edge angle of wiper edges part different from the chamfered edge angle at chamfering circular arc place, solve and improve sometimes at the cutting force relevant to wiper insert, blade produces the problem in crescent moon low-lying area, improve the surface quality of processing work, reduce percent defective, extend the service life of blade.
Description
Technical field
The utility model belongs to cutting tool field, is specifically related to a kind of integral sintered PcBN wiper insert.
Background technology
The workpiece surface quality of wiper insert processing is better than general blade, and at present, wiper edges technology a kind ofly approvedly can shorten the process-cycle and the mode boosted productivity.But when the cutting force relevant to wiper insert improves sometimes, blade can produce crescent hollow abrasion, affects the surface quality of workpiece, reduces the service life of blade.
Utility model content
The technical problems to be solved in the utility model is: during processing work, when the cutting force relevant to wiper insert improves sometimes, blade can produce crescent hollow abrasion, affect the surface quality of workpiece, reduce the service life of blade, for solving the problem, provide a kind of integral sintered PcBN wiper insert.
The purpose of this utility model realizes in the following manner:
A kind of integral sintered PcBN wiper insert, comprise blade body, described blade body is wiper insert, and blade body is processed with chamfered edge, and the chamfered edge angle of wiper edges part is less than the chamfered edge angle at tool arc place.
The chamfered edge angle of described wiper edges part is E, and the chamfered edge angle at tool arc place is D, 0 ° of < D < E≤25 °.
The chamfered edge angle that described blade body is processed all is not more than 25 °.
The shape of described blade body is triangle, regular polygon or rhombus.
Relative to prior art, the utility model adopts the chamfered edge angle of wiper edges part different from the chamfered edge angle at chamfering circular arc place, solve and improve sometimes at the cutting force relevant to wiper insert, blade produces the problem in crescent moon low-lying area, improve the surface quality of processing work, reduce percent defective, extend the service life of blade.
