Reciprocating friction drive-type ultra precision machine

摘要

A reciprocating friction-type mirror finishing machine which has a simple construction and performs easily adjustable feeding mode under micrometer scale is disclosed. This machine includes a driving device for generating a driving force in response to a swing motion thereof, and a friction device connected with the driving device for performing alternately clockwise and counterclockwise rotation relative to a work stand in contact therewith to generate a linearly reciprocating frictional force in response to the driving force. The frictional force allows a work piece held by the work stand to be fed in a linearly reciprocating motion to be ground.
