MANUFACTURING DEVICE FOR PHONOGRAPH NEEDLES

摘要

The device consists of a tubular shaft inside of which a flexible bushing is located, connected to a rod and tensioned by means of a spring. The bushing and rod glide inside the tubular shaft, driven by a handle eccentric, allowing the insertion and removal of the processing part. The shaft is operated by a motor through belt wheels and the belt, and is guided by the bearings mounted on a base, which, gliding on the upper wedge piece, can be fixed in any position on the upper slide. The upper slide is driven by a screw and moves lengthwise.
