A SIMPLE DIFFERENTIAL MICROMETER HEAD

B S Ramaprasad

Abstract


The paper describes the design and fabrication of a differential micrometer head with an equivalent pitch of 35 microns capable of a resolution of about 0 . 1micron. A teflon nut is used to reduce backlash. The performance of two models,one using teflon and the other using a brass nut, is compared.
