Embodiment 1

[0011] 1. Take 70 grams of diamond micropowder abrasive grains, 30 grams of hydroxyl iron powder, and 30 grams of resin, mix and stir evenly;

[0012] 2. The mixture obtained in step 1 is subjected to conventional heat treatment, and the temperature range is 70 ° C to 120 ° C. In order to prevent the generation of air bubbles, 5 grams of defoaming agent is added during heat treatment;

[0013] 3. Pour the mixture obtained in step 2 into the preset magnetron grinding wheel mold, and at the same time apply a magnetic field obtained by a fixed magnet or a speed-adjustable rotating magnet to the casting in the mold by conventional methods, so that the above-mentioned hydroxyl iron in the casting in the mold The powder is arranged regularly under the action of a magnetic field, so that the diamond micropowder abrasive grains in the casting are also arranged regularly, and then cooled for 10 to 60 minutes, and the casting is solidified and demoulded to obtain a finished product.

Embodiment 2

[0015] 1. Take 95 grams of diamond micropowder abrasive grains, 40 grams of hydroxyl iron powder, and 50 grams of resin, mix and stir evenly;

[0016] 2. The mixture obtained in step 1 is subjected to conventional heat treatment, and the temperature range is 70°C to 120°C;

[0017] 3. Pour the mixture obtained in step 2 into the preset magnetron grinding wheel mold, and at the same time apply an electromagnetic field to the casting in the mold by the conventional method, so that the above-mentioned hydroxyl iron powder in the casting in the mold is arranged regularly under the action of the magnetic field, so that the castable The diamond micropowder abrasive grains are also arranged regularly, and then cooled for 10-60 minutes, and the cast material in the mold is solidified and demoulded to obtain a finished product.

Abstract

The invention relates to a method for producing a magnetic control sand wheel, which comprises the following steps of: 1, mixing and stirring diamond micro powder abrasive particles, iron carbonyl powder and resin according to a weight ratio of (70-95):(30-40):(30-50); 2, heating conventionally at the temperature of between 70 and 120 DEG C; and 3, injecting a magnetic control sand wheel die, applying an electromagnetic field to ensure that the iron carbonyl powder and the diamond micro powder abrasive particles in a pouring object are arranged regularly, cooling and demolding to obtain a finished product. In the magnetic control sand wheel produced by the method, an abrasive layer is uniform in particle sizes and distribution of the abrasive particles, the magnetic control sand wheel is small in volume and difficult to deform, the ground surface of the sand wheel is uniform in quality during ultraprecise grinding, the cost is reduced, and the quality is improved, so the method is a machining process which meets the environmentally-friendly requirement.

Description

technical field [0001] The invention relates to the technical field of precision finishing, in particular to a production method of a magnetically controlled grinding wheel, which is suitable for precision grinding of tiny aspheric optical parts and molds thereof. Background technique [0002] High-quality aspheric mirrors are widely used in high-precision optical systems. The problem is that the processing and manufacturing of these optical components and their molds is very demanding. In the manufacturing technology of micro-aspherical lenses and their optical molds of hard and brittle materials, the most effective way to maintain high shape accuracy and high surface quality is to use micro-powder grinding wheels with small diameters for nano-grinding of oblique-axis lenses. In order to meet the grinding requirements of microstructure products such as micro-aspherical surfaces, the microstructure oblique axis mirror grinding process has the following requirements for the ...
