METHOD AND APPARATUS FOR PRODUCING THREADS, IN PARTICULAR FOR DRILL STRINGS OR THE LIKE |
摘要 |
#CMT# #/CMT# Production of threads comprises mechanically producing a radial oscillation movement between a rotating tool and the workpiece. #CMT# : #/CMT# An independent claim is also included for a device for producing threads. Preferred Features: The radial oscillation movement is synchronized with the relative rotating movement. The oscillation movement is produced using a cam plate. The rotating tool moves relative to the workpiece using the cam plate and is moved against the spring force by the cam plate. #CMT#USE : #/CMT# For drill strings. #CMT#ADVANTAGE : #/CMT# High productivity is achieved. |
