Abstract

The utility model discloses a boring cutter for processing cylinder holes. The boring cutter comprises a cutter body, one side of the front end of the cutter body is provided with a cutting part, the cutter tip part of the cutting part is in an arc chamfer structure, and the chamfer radius R is from 0.4mm to 0.6mm. The cutter tip of the boring cutter cutting part is in an arc structure. The cutter tip part of the cutting part is changed into an arc structure from a right angle structure, so workpiece cutting and processing precision is greatly improved, workpiece quality is greatly improved, and the service life of the boring cutter is extended. The cutter tip angle of the cutting part is changed into 105 degrees plus or minus 30 seconds from 90 degrees, so the boring cutter is more suitable for precisely boring cylinder holes. The utility model having the advantages of simple structure and reasonable design can improve workpiece processing precision, extend the service life, improve processing efficiency and increase product competitiveness.

Description

A kind of boring cutter that is used for the processing cylinder hole
Technical field
The utility model belongs to the Machining Technology field, particularly a kind of boring cutter that is used for machining high-precision cylinder hole.
Background technology
Along with development of science and technology, machinery manufacturing industry also is more and more higher to the requirement of machining accuracy, adopts boring cutter to carry out bore hole as the processing of cylinder inner bore, and boring cutter can directly influence the machining accuracy of machine-building.At present, the boring cutter cutting tip 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.The point of a knife of cutting tip is a right-angle structure, does not have circular arc, and the nose angle number of degrees are 90 °, and through the workpiece of this kind boring cutter machining, machining accuracy is lower, and boring cutter is short service life, and working (machining) efficiency is low.
The utility model content
The purpose of this utility model provides the boring cutter that is used for the processing cylinder hole of a kind of machining accuracy height, long service life.
For achieving the above object, the technical solution of the utility model is: a kind of boring cutter that is used for the processing cylinder hole, comprise cutter hub, and cutter hub front end one side is provided with cutting tip, and the point of a knife place of described cutting tip is the circular arc chamfering structure, and chamfer radius R is 0.5 ± 0.1mm.
The radius R of described circular arc is 0.5mm.
The nose angle number of degrees of described blade are 105 ° ± 30 '.
The point of a knife of the utility model cutting tip is an arc structure, the point of a knife part of cutting tip changes arc structure into by right-angle structure, has increased the contact area of cutting, and the precision of machining workpieces improves greatly, the workpiece quality also greatly promotes, and has prolonged the service life of boring cutter.The nose angle number of degrees of cutting tip by 90 ° become 105 ° ± 30 ', make boring cutter be more suitable for right boring cylinder hole.The utility model is simple in structure, reasonable in design, can improve the machining accuracy of workpiece, increases the service life, and improves working (machining) efficiency, strengthens product competitiveness.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
The boring cutter that is used for the processing cylinder hole as shown in Figure 1 and Figure 2, it comprises cutter hub 1, front end one side of cutter hub 1 is provided with cutting tip 2.Cutting tip 2 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 and cutter hub 1 are in the same place by solder bond.Point of a knife 3 places of cutting tip 2 are designed to the circular arc chamfering structure, and the radius of described circular arc chamfering is 0.5 ± 0.1mm.In the present embodiment, the radius R of circular arc chamfering is taken as 0.5mm.The number of degrees of the nose angle β of cutting tip 2 are 105 ° ± 30 ', the number of degrees of relief angle α are 10 °.
The utility model is specially adapted to process the endoporus of cylinder body, machining accuracy height, working (machining) efficiency height, the prolongation of looking cutter life.
Be not limited to above-mentioned embodiment: the radius of point of a knife of the present utility model place circular arc chamfering is not limited to the foregoing description, also can get 0.45mm or 0.55mm.

Claims (3)

1. a boring cutter that is used for the processing cylinder hole comprises cutter hub, and cutter hub front end one side is provided with cutting tip, it is characterized in that: the point of a knife place of described cutting tip is the circular arc chamfering structure, and chamfer radius R is 0.5 ± 0.1mm.
2. the boring cutter that is used for the processing cylinder hole as claimed in claim 1 is characterized in that: the radius R of described circular arc is 0.5mm.
