Method for trimming laser auxiliary mechanical diamond grinding wheel based on fiber-optical laser

Abstract

The invention discloses a method of laser-assisted mechanical dressing and truing of diamond grinding wheel based on a fiber laser, the specific steps are as follows: 1. Install and fix the fiber laser above the dressed diamond grinding wheel, and then a laser beam after focusing lights on the surface of dressed diamond grinding wheel, and finally a temperature filed is formed to soften the binding element of the diamond grinding wheel; 2. Install the dressed diamond grinding wheel on a grinding machine, enable the wheel to be rotating, and make the single-point diamond dressing pen conduct the reciprocating movement along the axial direction of the surface of diamond grinding wheel, so as to dress the surface of the diamond grinding wheel. The invention solves the difficult problem that the on-line dressing on surfaces of diamond grinding wheels is impossible on a digital control optics curve grinding machine and a tool grinding machine. The method uses the fiber laser to build the temperature field and the method has a simple structure, which can be conveniently applicable to various grinders, in particular to the digital control optics curve grinding machine, wherein the on-line dressing of the diamond grinding wheel on the digital control optics curve grinding machine is high-efficiency and high-precision, and non coolants are adopted.

Description

technical field [0001] The invention relates to a method for dressing a diamond grinding wheel, in particular to a laser-assisted mechanical diamond grinding wheel method based on a fiber laser, and 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 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 and brittle For normal...

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.

In addition, the applicant once proposed a method for dressing diamond grinding wheels based on discharge-assisted machinery in gas, and developed a corresponding dresser (invention patent authorization announcement number: CN1297371C). Although this dresser can dress diamond grinding wheels on-line, it has poor electrical conductivity The dressing effect of the resin bonded diamond grinding wheel is not ideal, and the dressing device is more complicated
