Abstract

The invention belongs to the technical field of machining, and relates to a machining efficient reverse chamfer milling cutter. A hole bottom chamfer cannot be processed since the position of the hole bottom is interfered in the prior art. For solving the problem in the prior art, the technical scheme provided by the invention is as follows: the machining efficient reverse chamfer milling cutter comprises a cutter rod and a blade at the end part of the cutter rod, the blade is a reverse blade. The milling cutter provided by the invention is capable of guaranteeing the one-time accomplishment for a complex surface inner hole chamfer, the processing efficiency is 20 times of the traditional fitter chamfer. The consistency and high size precision of the reverse chamfer are greatly improved, and the turned burr is avoided.

Description

Machined is instead angular cutter and using method thereof efficiently

Technical field

The invention belongs to the Machining Technology field, relate to a kind of novel machined efficiently instead angular cutter and using method thereof.

Background technology

At present, often run into the through hole reverse side chamfering of complex parts in mechanical processing process, interfere because there are other profiles bottom surface, position, hole, cause machining tool directly too large to the bottom surface difficulty of processing, even can't process.If adopt the pincers worker chamfering, because of nothing processing visual angle, the workman can't adjust by visual, and easily residual a large amount of flanging burrs can't be removed on the limit, hole, and working (machining) efficiency is low, and uniformity is poor, and the processing risk is high, is difficult to reach the final requirement of part.Now by constantly attempting and test, invented a kind of complex parts of ignoring, the instead angular cutter that can directly process from the front on Digit Control Machine Tool has solved this difficult problem.

Summary of the invention

The purpose of this invention is to provide a kind of machined efficiently instead angular cutter and using method thereof, solving prior art owing to having interference in position, bottom surface, hole, thus technical barrier that can't the machining hole bottom chamfer.

Be to solve the problem that prior art exists, technical scheme provided by the invention is: a kind of machined is angular cutter instead efficiently, comprises knife bar and is arranged at the blade of knife bar end, and its special character is: described blade is reverse blade.

The angle of above-mentioned blade and knife bar bus extended line is 15 ° ~ 75 °.

The maximum rotating diameter of above-mentioned blade is 4mm ~ 20mm.

Above-mentioned blade is 4 and distributes along the knife bar even circumferential.

The bus angle of above-mentioned knife bar is 0 ° ~ 10 °.

The efficient instead using method of angular cutter of above-mentioned a kind of machined comprises the following steps:

The first step: with the efficient instead angular cutter fast moving of machined to the top position at center, part to be processed hole;

Second step: with the efficient instead angular cutter of machined along the lower position of centerline hole fast moving to the part to be processed hole;

The 3rd step: with the efficient angular cutter skew certain distance instead of machined, cutter blade is contacted with the part to be processed Hole chamfering;

The 4th the step: with machined efficiently instead angular cutter mill one week of machining hole chamfering around the hole central rotation;

The 5th the step: with machined efficiently instead angular cutter move to the center, hole;

The 6th step: above efficiently instead angular cutter moves to part to be processed along centerline hole fast with machined.

The present invention has following advantage and effect with respect to prior art:

1. can guarantee to complete the complex profile inner bore chamfering is disposable, working (machining) efficiency is 20 times of traditional pincers worker chamfering.Improved greatly simultaneously instead the uniformity at angle and higher dimensional accuracy, and the noresidue flanging burr.

2. the angle of blade and knife bar bus extended line is 15 ° ~ 75 °, and the maximum rotating diameter of blade is 4mm ~ 20mm, can be according to the big or small and suitable milling cutter of size selection instead angle in processing aperture.

3. blade is 4 and distributes along the knife bar even circumferential, makes processing more efficient, quick.
