Embodiment Construction

[0038] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0039] Such as Figure 1-Figure 6 As shown, a superabrasive grinding wheel composite efficient precision dressing method comprises the following steps:

[0040] Step 1. Abrasive Waterjet Rough Repair:

[0041] The superabrasive grinding wheel rotates at a certain speed, and the injection direction of the abrasive water jet 3 is perpendicular to the axis of the superabrasive grinding wheel 1, and forms a certain angle with the tangent line of the outer circle of the superabrasive grinding wheel 1. The tangent line of the outer circle is consistent, and the spraying effect is small. If the angle is too large, it is easy to remove too much bonding agent and abrasive particles. Therefore, the angle should be controlled within a reasonable small angle range;

[0042] At the same time, the abrasive water jet nozzle 2 reciprocates along the cr...

Abstract

The invention provides an ultrahard abrasive grinding wheel compounded efficient and precise finishing method. The method comprises the following steps: (1) abrasive water jet rough finishing: abrasive water jet is sprayed to a direction with a certain angle; meanwhile, an abrasive water jet nozzle performs a reciprocating motion along a section profile trajectory of a molded surface needed by a grinding wheel; and an ultrahard abrasive grinding wheel is radially fed to realize rough finishing; (2) a finishing roller and a free abrasive are used for extrusion and finishing; abrasive water jetspray heads are arranged in a row; and the jet flow of each spray head is controlled to match with a finishing roller for finishing; and (3) the abrasive water jet is used for finishing sharpness. Theultrahard abrasive grinding wheel compounded efficient and precise finishing method is simple in process, high in finishing precision and suitable for the finishing work of ultrahard abrasive grinding wheels with complex molded surfaces.

Description

technical field [0001] The invention relates to the field of dressing of grinding wheels, in particular to a composite high-efficiency and precise dressing method of superhard abrasive grinding wheels. Background technique [0002] Form grinding technology is the main method to obtain high-quality parts with complex profiles. Therefore, the grinding wheel needs to be trimmed before use to obtain the processing surface of the corresponding profile. [0003] At present, although the metal-bonded grinding wheel prepared by diamond and CBN (cubic boron nitride) superabrasives has excellent characteristics such as high chemical stability, high wear resistance, and long service life, it also brings great difficulty in dressing. The problem. When using traditional dressing methods such as turning dressing method, cup wheel dressing method, and diamond roller dressing method to dress the above-mentioned superabrasive grinding wheel, there are generally problems such as fast wear of...
