Description
Technical field
The utility model relates to the technical field of composite milling cutter, particularly relates to a kind of iblet diamond finish-milling cutter.
Background technology
The iblet milling cutter, its blade is embedded in the surface of knife bar, and shape as its name suggests, generally is iblet milling cutter, corn ear milling cutter as maize cob.
Existing iblet milling cutter exists and collapses the cutter phenomenon, and also fall short of its service life because its blade structure shaped design is not very rationally, and crudy can not be improved, and haves much room for improvement.
The utility model content
The purpose of the utility model is in order to address the above problem, a kind of iblet diamond finish-milling cutter to be provided.
The technical scheme of the utility model is: a kind of iblet diamond finish-milling cutter; Comprise cutter hub and blade; Described cutter hub afterbody is for installing the clamping cone, and the cutter hub front portion is an inverted cone, and the front portion of described cutter hub is distributed with six right angle V-arrangement chip areas around the cutter hub axis along taper seat; The line of one of them side of described each V-arrangement chip area and the radial parallel of cone, the axis of this side and cutter hub has 5 ° angle, through the welding embedding three blades is arranged on this side; Three blades stretch out the side surface of cone; The blade of the outermost end in said six V-arrangement chip areas all stretches out the end face of cutter hub, and this blade has two kinds of first, second, is crisscross arranged respectively in six V-arrangement chip areas; Described first blade is that cutting edge is the structure of right angle band circular arc point of a knife; The cutting edge of described second blade is the acute angle cutting edge and has the circular arc point of a knife that the point of a knife of second blade stretches out certain-length L than the point of a knife of first blade more, 0.8mm≤L≤1.3mm.
The axial end of the outermost end blade in described six V-arrangement chip areas is a combinatorial surface; There are angle in the epimere of said combinatorial surface and hypomere with perpendicular respectively; The angle of hypomere end face and perpendicular is 30'; The angle of epimere end face and perpendicular is 2 °, and the vertical length of said hypomere end face is 1mm, forms oblique extruding wiper edges.
The afterbody of described right angle V-arrangement chip area is arc surface transition and crossing with described cylindrical side surface.
The end face middle part of described cone is provided with the cylindrical depression of certain depth.
The material of described cutter hub is GCr15, and the material of described blade is a polycrystalline diamond.
The beneficial effect of the utility model
The iblet diamond finish-milling cutter of the utility model, the cutting edge of described second blade are the acute angle cutting edge and have the circular arc point of a knife that the point of a knife of second blade stretches out certain-length L than the point of a knife of first blade more.This is the escape of processing work bottom for ease, guarantees processing linear degree and machined surface roughness.
Described first blade is that cutting edge is the structure of right angle band circular arc point of a knife, is in order to reduce the processing resistance, to avoid the stressed excessive tipping that causes in the cutter process, and the cutting edge of circular arc processing simultaneously improves crudy by putting the line contact, improves cutter life.
Increase the extruding wiper edges, can push cutting, improved machined surface quality.
