Abstract

The invention provides a taper and ball-end milling cutter. The milling cutter comprises a head part, a neck part connected with the head part, and a handle part connected with the neck part, wherein the head part is provided with a chip removal slot, an entity part used for forming the chip removal slot, and a cutting edge formed at an intersection line between the chip removal slot and the entity part, wherein the cutting edge is provided with a front cutter face and a rear cutter face, the front cutter surface and the rear cutter surface are contacted and form a front angle, and the rear cutter face of the cutting edge and a machining piece are contacted and form two rear angles, including the first rear angle and the second rear angle respectively. According to the taper and ball-end cutter provided by the invention, the front angle and the rear angles are reasonably designed, so that the rigidity of the milling cutter is guaranteed, the sharp degree of the milling cutter is guaranteed at the same time, and the probability of burr generation in a milling process is effectively reduced; the taper and ball-end milling cutter has a long service life and can keep good surface roughness when machining an aluminum alloy pressure wheel.

Description

technical field

[0001] The invention belongs to the technical field of aluminum alloy pressure wheels, and in particular relates to a tapered ball end milling cutter. Background technique

[0002] The integral pressure wheel is the core component of the gas turbine and turbocharger. The pressure wheel is widely used in energy power, aerospace, petrochemical, metallurgy and other industries. It is representative, and its shape is relatively standardized and typical. Channel-like complex parts of . The processing method, processing accuracy and processing surface quality of the aluminum alloy pressure wheel directly affect the aerodynamic performance and mechanical efficiency of the engine, and have a decisive impact on the engine performance. The integral pressure wheel is a typical difficult-to-machine part because of its complex surface and high machining accuracy. At present, the most commonly used material for integral pressure wheels is aluminum alloy.
