Abrasive cutoff wheels should not be used in the preparation of tubular products, because abrasive dust from the wheels is detrimental to the swaging dies and to the machine. Although the abrasive dust can be removed from the outside surface of the...

... transfer headers. Most cold-heading machines used in high production are fed by coiled wire stock. In the conventional method, stock is fed into the machine by feed rolls and passes through a stationary cutoff quill. In front of the quill is a shear-and-transfer mechanism. When the wire passes through...

Robots are very good at following a path and moving very accurately to a point, but due to scan times from an input device, they...
