Problems solved by technology

However, since this method must use kerosene or No. 20 engine oil as the medium, and the dressing efficiency is low, it cannot meet the high-efficiency and high-precision online dressing of diamond grinding wheels under the condition that no coolant can be used.

Embodiment Construction

[0017] The following examples are provided in conjunction with the content of the method of the present invention:

[0018] This experiment is carried out on the latest product MK9025 CNC optical curve grinding machine produced by a certain machine tool factory in Shanghai. The grinding wheel to be trimmed is a bronze foundation diamond grinding wheel produced by Shanghai Grinding Wheel Factory. The model of the grinding wheel is 1A1 / T2 200×6×32×4 MBD3 120 / 140 M75. The servo motor is Panasonic AC SERVO MOTOR model MSMA082A1G, the diamond pen is a 1 carat / grain diamond pen produced by Shanghai Diamond Tool Factory, and the WTYD0808020 piezoelectric ceramic produced by Sichuan Piezoelectric and Acousto-optic Technology Research Institute is combined with the servo motor. , to achieve micro-step servo feeding of electrodes and diamond pens. In order to avoid the unfavorable factors caused by the use of cooling liquid, the copper electrode and the two poles of the diamond grindi...

Abstract

The present invention is air discharge method for auxiliary in-situ trimming of grinding diamond wheel and belongs to the field of precise machining technology. The present invention includes three steps of establishing spark discharge temperature field in air, trimming with diamond pen under air discharge and controlling the sustained air discharge. In the first step, the discharge between electrode and grinding wheel in the air establishes temperature field to soften adhering metal material in grinding diamond wheel; in the second step, the grinding wheel rotates and the trimming diamond pen reciprocates in the surface of the grinding wheel to trim the softened binding agent material mechanically; and in the third step, the measuring link, control link and executing link complete the control for sustained discharge. The present invention realizes the in-situ trimming of grinding diamond wheel at high efficiency, high precision and low cost.

Description

technical field [0001] The invention relates to a method for dressing a diamond grinding wheel, in particular to a method for on-line dressing of a diamond grinding wheel based on in-gas discharge assistance. It belongs to the technical field of precision machining. Background technique [0002] Diamond grinding wheels have excellent grinding performance and are widely used in the grinding of difficult-to-machine materials. The binders used for diamond grinding wheels include metal, resin, ceramics, etc., and the commonly used metal (bronze) and resin bond diamond grinding wheels occupy a more important position in the application. However, the self-sharpening of the diamond grinding wheel is poor, it is easy to block, and it is easy to generate the excitation force caused by the eccentricity of the grinding wheel during the grinding process, which affects the stability of the grinding process and the quality of the grinding surface, thus limiting its high performance hard ...
