Machining method of red rubber sheet through hole

The invention discloses a machining method of a red rubber sheet through hole. The method includes: placing an aluminum sheet on a base plate; fixing a to-be-machined red rubber sheet on the aluminum sheet; smearing lubricant on the surface of the to-be-machined red rubber sheet; placing another aluminum sheet on the to-be-machined red rubber sheet, and smearing lubricant on the aluminum sheet; drilling the through hole on the to-be-machined red rubber sheet; removing residual lubricant on the red rubber sheet. The method has the advantages that the radiation design introducing the aluminum sheets and lubricant is used, radiation of red rubber sheet drilling is improved, modification, caused by excessive heat, of the red rubber sheet can be avoided, and excellent quality of the red rubber sheet through hole can be guaranteed; due to the enhanced radiation capability, excessive heat of the red rubber sheet can be avoided even drilling speed is increased moderately, low drilling efficiency ...
