Embodiment 1

[0043] Such as Figure 1 to Figure 6 Shown, the sharpening method of a kind of arc-shaped diamond grinding wheel of the present invention comprises the following steps:

[0044] Step 1. On-site detection of the surface profile accuracy of the arc-shaped grinding wheel and tool calibration. The laser micrometer moves at a constant speed of 15mm / min to measure the grinding wheel rotating at 400rev / min. The sampling frequency is 50KHz and the sampling accuracy is 0.1μm. The obtained sampling points are the feature points of the height information on the arc surface of the grinding wheel, and the height information of the highest point is obtained by comparison, and the protrusion height of the highest point (denoted as t) is the total cutting depth of the laser water jet 2 on the grinding wheel surface in step 2 . Fine shaping tool setting position 5 is attached figure 1 As shown, adjust the relative position of the grinding wheel and the laser water beam so that the distance b...

Abstract

The invention provides a sharpening method of a circular arc diamond grinding wheel. The method comprises the following radially sharpening steps of enabling a laser water beam to incident upon the surface of the shaped circular arc grinding wheel along a radial direction of the grinding wheel, enabling the laser water beam to scan at the variable-rate scanning speed along an axial direction of the grinding wheel, and uniformly removing a binding agent material so as to realize uniform protrusion of abrasive particles. According to the sharpening method of the circular arc diamond grinding wheel provided by the invention, a high-energy-density laser beam is guided by the water beam, a grinding wheel material is removed by adopting melting and gasifying as principal manners, and a mathematic model for laser water beam variable-rate scanning is provided, so that the uniformity in removing the grinding wheel surface binding agent and the consistency of the protrusion heights of the abrasive particles are ensured, the sharpened grinding wheel is good in surface appearance and high in sharpening accuracy, the sharpening quality is ensured through the cooling and scouring actions of thewater beam, and energy conservation and environment friendliness are realized.

Description

technical field [0001] The invention belongs to a sharpening method of a grinding wheel, and in particular relates to a sharpening method of an arc-shaped diamond grinding wheel. Background technique [0002] In recent years, complex curved surface parts (such as optical lenses, microstructure molds) have been more and more widely used in national defense, aerospace and other fields. For these parts, which are mostly made of hard and brittle materials such as ceramics, optical glass, and cemented carbide, The ultra-precision grinding technology based on diamond grinding wheel is an effective means for its processing. Metal-based arc-shaped diamond grinding wheel is a kind of high-efficiency, high-precision, long-life bonded abrasive prepared by metal as the binder and diamond as the abrasive. It is an important tool for ultra-precision grinding of spherical, aspheric, and free-form surfaces for high-speed, high-efficiency, and ultra-precision machining of various difficult-...
