Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] refer to Figure 1 ~ Figure 3 , a kind of processing method of complicated surface cutting tool, described processing method comprises the following steps:

[0044] (1) According to the structure and size requirements of the tool to be processed, the tool electrode is designed according to the tool design theory and the processing principle of the profiling method;

[0045] (2) Use the tool electrode to trim the profile of the grinding wheel, including:

[0046](2.1), the metal bond diamond grinding wheel is connected to the positive pole of the high-frequency pulse power supply through the anode fixing device as the anode, and the tool electrode is connected to the negative pole of the high-frequency pulse power supply as the cathode;

[0047] (2.2), between the metal-bonded diamond grinding wheel and the tool electrode, a medium with conducting poles and coo...

Abstract

The invention provides a processing method of a cutter with complex profile, comprising the steps as follows: (1) a dressing electrode is designed according to the structure and size requirement of the cutter to be processed, the design theory of the cutter and the processing principle of the profile modeling method; (2) the profile of a grinding wheel is dressed by the dressing electrode; (3) the dressing electrode is grinded and processed by the grinding wheel with profile dressed; and (4) no-pressure rolling grinding and impact polishing of the surface of the workpiece which is online electrolyzed, dressed and grinded are carried out to gain the hard alloy cutter. The invention provides the processing method for the cutter with complex profile, which has high dressing efficiency and low cost.

Description

technical field [0001] The invention relates to the field of precision machining, in particular to a machining method for complex profile cutters. Background technique [0002] The bearing groove is the key working surface of the rolling bearing, and its surface quality directly affects the performance of the entire rolling bearing. Among them, the surface roughness of the inner and outer grooves is the main reason affecting the vibration of the bearing, so the requirements for the tools for processing the bearing grooves are put forward. [0003] Carbide bearing cutting tools are mainly used for forming processing on turning automatic lines and special processing machines in bearing processing. The tools include indexable groove cutters, seal groove cutters, end face chamfer R angle cutters, welded inner ring groove and seal groove cutters, outer ring seal groove cutters, outer ring groove cutters, etc. These forming tools are turned and formed at one time during processi...
