Description

Detachable end mill for aviation

Technical Field

The application relates to the technical field of end milling cutters, in particular to a detachable end milling cutter for aviation.

Background

The end mill installed in the market in cooperation with a machining center is designed into a Morse cone shape mostly according to the Morse cone degree, and the installation part of the end mill is designed into a cone rod with a certain angle.

Morse taper is an international standard for taper, used for interference fit to precise location. Because the taper is very small, the principle of utilizing frictional force can transmit certain moment of torsion, because be the taper fit, so can convenient dismantlement. At same tapering certain limit, the dismouting that the work piece can be free can not influence the result of use at the during operation again simultaneously, for example the taper shank of drilling bores, if in the use need dismantle the drill bit grinding, adorns the central point that can not influence the drill bit again after the dismantlement and puts.

So the end mill of cooperation morse's circular cone, with the installation accuracy height, the simple and convenient advantage of dismouting applies to the aviation field in a large number, but when end mill was the cutting work, the piece that splashes can imbed the junction of installing port and cutter arbor, can rub the edge of connector in high-speed rotation and lead to the damage, there is not strong problem in the end mill of using morse's circular cone itself, so can not be used for cutting the selection high rigidity metal, if the installing port damage, then influence the installation accuracy more easily, also be not enough because of stability in the work, lead to the blade to split.

It is therefore desirable to provide a demountable end mill for aviation that solves the above problems.
