Abstract
The utility model relates to a face-milling blade for fine milling in machining a cylinder cover of an engine, comprising a cutting part. The cutting part is arranged at one corner of the face-milling blade; a cutting edge of the cutting part has an arc structure; an arc-shaped sleeking edge is arranged at the rear side of the arc structure; an included angle between the front side surface of the sleeking edge and the horizontal direction is 30 degrees+/-10 minutes, and an included angle between the rear side surface of the sleeking edge and the horizontal direction is 25 degrees+/-30 minutes; and the radius of the arc of the sleeking edge is 400mm. In the face-milling blade, the structure is simple, the function is practical, the straight line at the rear side of the cutting part is changed into the arc, the machining quality of the surface of a workpiece is improved, and the machining life of a tool is also prolonged.
Description
Technical field
The utility model belongs to the Machining Technology field, relates in particular to a kind of face-milling insert that is used to process the engine cylinder cover finish-milling.
Background technology
The structure that is used to process the face-milling insert of engine cylinder cover finish-milling directly influences the precision of machining, the cutting tip of current blade mainly is composite polycrystal-diamond (or polycrystalline cubic boron nitride composite sheet), this composite sheet is formed through the HTHP compacting by polycrystalline diamond layer (or polycrystalline cubic boron nitride layer) and hard alloy layer, and composite sheet is in the same place by solder bond with cutter hub.In the present cutter structure, the cutting edge rear side is straight sword, scratches surface of the work in the blade process easily, reduces crudy and precision.
The utility model content
The utility model purpose is to provide a kind of face-milling insert of processing the engine cylinder cover finish-milling, has improved the suface processing quality of workpiece, has also prolonged the processing life-span of cutter.
To achieve these goals, the utility model adopts following technical scheme: the face-milling insert of processing engine cylinder cover finish-milling, comprise cutting tip, described cutting tip is arranged on a jiao of face-milling insert, the cutting edge of cutting tip is an arc structure, described arc structure rear side is provided with the wiper edges of circular arc, and wiper edges front side surface and horizontal direction angle are 30 ° ± 10', and wiper edges rear side surface and horizontal direction angle are 25 ° ± 30'.
The arc radius of described wiper edges is 400mm.
The utility model is simple in structure, function is practical, the straight line of cutting tip rear side is made into circular arc after, reduced blade in the contact-making surface of workpiece and the interference at other positions, improved the suface processing quality of workpiece, the processing life-span of the cutter that has prolonged simultaneously.。
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model;
Fig. 3 is an I place structure for amplifying schematic diagram among Fig. 1.
The specific embodiment
Embodiment: as Figure 1-3, the face-milling insert 1 of processing engine cylinder cover finish-milling, comprise cutting tip 2, cutting tip 2 is arranged on a jiao of face-milling insert, the cutting edge of cutting tip 2 is arc structure R1, arc structure R1 rear side is provided with the wiper edges of circular arc, and wiper edges front side surface and horizontal direction angle α are 30 ° ± 10', and wiper edges rear side surface and horizontal direction angle β are 25 ° ± 30'.The arc radius R2 of wiper edges is 400mm.
Because arc structure R1 rear side is provided with the wiper edges of circular arc, reduced the contact-making surface of blade and workpiece and the interference at other positions, improved the suface processing quality of workpiece, in the processing life-span of the cutter that has prolonged simultaneously, reduced processing cost.
Claims (2)
