Embodiment Construction

[0032] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] The invention provides an end mill, such as figure 1 as well as figure 2 As shown, the described includes a cutter body 1 and a cutter tooth 2, and the cutter tooth 2 described in the present invention can be a multi-edged spiral cutter. The cutting edge 21 and the polycrystalline hexagonal boron nitride (CBN) cutting edge 22 are arranged at intervals. When milling, the side wall and bottom surface of the workpiece to be processed can be processed at one time at the same time, and the required processing technology can be achieved.

[0034] The structure of end mill shown in the present invention, as figure 1 and figure 2 As shown, wherein the cemented carbide blade and the CBN blade are arranged at intervals, and the polycrystalline hexagonal boron nitride (CBN) blade is higher than the hard alloy blade in the axial direction...

Abstract

The present invention relates to an end mill, which comprises a cutter body and cutter teeth, and is characterized in that the cutter teeth are multiple blade helix blade, and the hard alloy blade and the polycrystalline hexagonal boron nitride blade are arranged at intervals, such that a side wall and a bottom surface of a workpiece can be simultaneously milled. During a production process, with the end mill of the present invention, production cost can be reduced, and products with excellent quality can be obtained. The present invention further provides a method for milling a compressor scroll part by using the end mill. The method mainly comprises the following steps: adopting a corrugated rough milling cutter to carry out semi-finish milling on a machined compressor scroll part; adopting the end mill to carry out finish milling on the semi-finish milled compressor scroll part; and completing a milling process of the compressor scroll part.

Description

technical field [0001] The invention relates to a milling cutter, in particular to an end mill used in the milling process of nodular cast iron materials and a method for using the milling cutter to mill scroll parts of a compressor. The end mill of the invention is used in the production process Production costs can be reduced and products of good quality can be obtained. Background technique [0002] In the general machining process, milling is one of the essential steps. Usually milling refers to the use of a rotating multi-blade tool to cut the workpiece, which is a high-efficiency processing method. The tool (that is, milling cutter, milling cutter) is fixed on the machine tool. During milling, the tool rotates as the main movement, and the workpiece to be processed In the actual production process, the workpiece can also be fixed, but at this time the rotating tool must also move to complete the main movement and the feed movement at the same time. Among them, the mi...
