Abstract
The invention belongs to the technical field of machining, and relates to a cutter for machining a chute of an inner hole of a rotary body, particularly to a milling cutter for the chute. The milling cutter comprises a cutter body, a blade arranged on the cutter body and a cutting edge arranged on the blade. The milling cutter is characterized in that the cutting edge is an arc transition edge. The size of the arc diameter of the cutting edge accords with the size of the chute diameter of a workpiece to be machined. After adoption of the technology, the milling cutter has the advantages that the cutter is simple in structure; the cutting edge in the arc transition is even in acting force, good in rigidity and not easy to deform and break; and the size of the arc diameter of the cutting edge accords with the size of the chute diameter of the workpiece to be machined, the machining size is accurate, and out-of-tolerance conditions can be avoided.
Description
Technical field
The invention belongs to the Machining Technology field, relate to a kind of cutter of revolving body endoporus skewed slot processing, be specially a kind of skewed slot milling cutter.
Background technology
The skewed slot milling cutter is a kind of machining tool for the processing skewed slot, in the prior art processing of revolving body endoporus skewed slot is often finished by the skewed slot milling cutter, the problem that exists is at the smaller workpiece of processing groove width especially groove width L during less than the workpiece of 2mm, the groove width size is overproof easily, and narrower because of groove width, and the power that causes the groove cutter to bear is larger, poor rigidity, the groove cutter just deforms even the situation of breaking easily like this, and cutting-tool's used life is had a greatly reduced quality, and the cutter use cost is very large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of skewed slot cutter simple in structure, ingenious, rational is provided, the technology that this skewed slot cutter adopts can effectively be avoided the generation of cutter distortion even breaking situation, effectively tool life.
According to technical scheme provided by the invention: a kind of skewed slot milling cutter, comprise cutter hub, be welded in blade on the cutter hub, drive the cutting edge on blade, be characterised in that: described cutting edge is the arc transition sword.The arc diameter size of described cutting edge and to be processed groove footpath consistent size.
Compared with prior art, the beneficial effect that the technology that the present invention adopts is brought is: cutter structure is simple, the cutting edge active force of arc transition is even, good rigidly, be difficult for deforming with the situation of breaking and because the groove footpath consistent size of the arc diameter size of cutting edge and workpiece to be processed, the size of processing is accurate, does not have overproof situation and occurs.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, described skewed slot milling cutter of the present invention, this skewed slot milling cutter comprise blade 2 on cutter hub 1, the cutter hub, drive the cutting edge 3 on blade, and described cutting edge 3 is the arc transition sword; The arc diameter size of described cutting edge 3 and to be processed groove footpath consistent size.
Claims (2)
1. skewed slot milling cutter comprises cutter hub (1), is welded in blade (2) on the cutter hub, drives the cutting edge (3) on blade, and it is characterized in that: described cutting edge (3) is the arc transition sword.
2. a kind of skewed slot milling cutter according to claim 1 is characterized in that: the arc diameter size of described cutting edge (3) and to be processed groove footpath consistent size.
