Dead center consists of a working part, a cylindrical part and a shank. The short spigot is used to knock the canine out of the nest (so as not to injure the cone). Working part of the cone can have a bevel that allows complete trans- porting of the face of the workpiece. If the nest in which the canine is mounted has no overflowing, then a canine with a nut is used, by means of which the can can be pulled out of the nest. For heavy turning machines (large chip section), solid fangs (stiffer structure, less vibrations) give better results.
