A technology has been developed for the manufacture of bushings from sintered washer-blanks obtained by slip casting under pressure from steatite sitall K-14. The technology of making watch stones on semi-automatic machines was adopted as a basis. The influence of laser radiation parameters on the process of piercing holes in blank washers to obtain bushings is investigated. Comparative properties of bushings are given.
