What is Automatic Bar Machining?
Automatic bar machining involves high-precision, high-speed production of large quantities of metal bar product in a variety of industries. This is done by you placing the bar through the spindle of the lathe, and a collet firmly grips the bar as it passes through the cutting tools that shape and form it in a continuous process. You get superior efficiency and close tolerances, which is ideal in small parts such as bushings, screws, and other threaded parts. The machine moves the bar automatically, cutting off finished pieces with little manual work required.
