Abstract
The utility model discloses a boring tool for machining an intake and exhaust guide pipe hole of a valve, comprising a tool holder and a tool head, wherein the included angle of an auxiliary cutting edge and a main cutting edge of the tool head is a tool tip angle Epsilon which is equal to 105 degrees+/-10 minutes. The tool tip is provided with a circular arc with the R being equal to 0.1-0.2. In the boring tool, the tool tip angle is increased by 15 degrees, and the tool tip is processed, so that the resistance in machining the tool is reduced, the machining quality of the surface of a workpiece is improved, and the service life of the tool is prolonged.
Description
Technical field
The utility model relates to the boring cutter field, especially relates to a kind of boring cutter that is used to process valve intake and exhaust guide hole.
Background technology
Boring cutter is a kind of of turning cutting tool, generally is the circle handle, also has big workpiece user knife bar generally to see vertical lathe, the most frequently used occasion be exactly in the hole process reaming, profiling etc.
Boring cutter has one or two cutting tip, is specifically designed to roughing, semifinishing or accurately machined cutter are carried out in existing hole.Boring cutter can use on boring machine, lathe or milling machine.Because of the difference of installation way, various ways such as the boring cutter shank side of having handle, Morse taper shank and 7:24 taper shank.
The cutting edge place of existing blade is the right angle, no drift angle.Because point of a knife is too sharp, tool resistance is bigger, has reduced working (machining) efficiency in the process.
The utility model content
The purpose of this utility model is to provide a kind of boring cutter that reduces cutter processing resistance.
The technical solution of the utility model is:
Be used to process the boring cutter of valve intake and exhaust guide hole, comprise handle of a knife and cutter head, the front cutting edge of cutter head and the angle of main cutting edge are nose angle ε, described nose angle ε=105 ° ± 10 ＇.
Circular arc R=0.1 ~ 0.2 is set on the described point of a knife.
The utility model increases 15 ° with nose angle, and point of a knife is handled, and has reduced the resistance of cutter processing, has improved the crudy of surface of the work, has prolonged the service life of cutter.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model comprises handle of a knife 1 and cutter head 2, and the front cutting edge of cutter head 23 is nose angle ε with the angle of main cutting edge 4, ε=90+15 ° ± 10 ＇=105 ° ± 10 ＇.Circular arc R=0.1 ~ 0.2 is set on point of a knife 5 simultaneously.Do the resistance that has reduced cutter processing like this, improved the crudy of surface of the work, prolonged the service life of cutter.
Claims (2)
1. be used to process the boring cutter of valve intake and exhaust guide hole, comprise handle of a knife and cutter head, the front cutting edge of cutter head and the angle of main cutting edge are nose angle ε, it is characterized in that: described nose angle ε=105 ° ± 10 ＇.
2. the boring cutter that is used to process valve intake and exhaust guide hole according to claim 1 is characterized in that: circular arc R=0.1 ~ 0.2 is set on the described point of a knife.
