Optical-grade acrylic surface treatment method for CNC machining

Abstract

The invention discloses an optical-grade acrylic surface treatment method for CNC machining, which comprises the following treatment steps: S1, raw material preparation: firstly, preparing dichloromethane and acetone, performing preparation according to a certain proportion, performing purification, then adding a proper amount of ethanol, and performing blending for later use; S2, heating: putting the blended raw materials below a beaker, and heating the raw material with an alcohol lamp; and S3, filtering: due to the fact that the heated raw material can generate gas evaporation, compressing gas with a hollow pipe with the small diameter. By adopting a special surface optical treatment method and a liquid smoking mode, surface optical treatment of CNC machined parts can be completed under the condition of no manual touch, the machining precision and designed optical data are guaranteed to the greatest extent, so that the defect of polishing by using external equipment can be avoided, the whole treatment process is simple and convenient, the machining work can be completed without people with strong working experience, so that the method is very convenient to use.

Description

technical field [0001] The invention relates to the technical field of plastic polymer materials, in particular to a method for CNC processing optical-grade acrylic surface treatment. Background technique [0002] Acrylic, also known as PMMA or plexiglass, and its chemical name is polymethyl methacrylate, is an important plastic polymer material developed earlier, with good transparency, chemical stability and weather resistance, easy to dye, easy Processing, beautiful appearance, widely used in the construction industry, plexiglass products can usually be divided into cast plate, extruded plate and molding compound. [0003] Most of the optical-grade effects in the surface treatment of acrylic on the market are manually polished and polished, which is not only time-consuming and labor-intensive, but also easily affected by the skill level of workers, resulting in unguaranteed accuracy and high production costs. As the number of products processed continues to increase, the...

[0003] Most of the optical-grade effects in the surface treatment of acrylic on the market are manually polished and polished, which is not only time-consuming and labor-intensive, but also easily affected by the skill level of workers, resulting in unguaranteed accuracy and high production costs. As the number of product processing continues to increase, the staff will experience a decrease in work efficiency, and there are certain limitations in actual operation
