Turning Machines

“Turning” defines the work that is traditionally done on a lathe. “Turning centers” is a term sometimes applied to machines with secondary spindles and/or rotating tools for milling and drilling. Another term, “turn/mill or multitasking” describes machines that can be thought of as being just as capable at milling and drilling as they are at turning. Lathes, turning centers and turn-mill machines can have horizontal or vertical spindles, with horizontal being most common. Machines with a vertical spindle are generally called a vertical turret lathe, or VTL. If the workpiece is held from above by the vertical spindle, then this type of turning machine is generally called an inverted vertical lathe.

Programming Considerations for Inverted Vertical Turning

Since its inception, the self-loading/unloading design of inverted vertical turning machines has evolved to include multitasking operations that augment its original task of turning. This article looks at ways to optimize the programming of these machines and to take advantage of the multiple operations available for workpiece processing.

Preparing for Lights-Out Production

As manufacturers face the challenges of reducing cost-per-part while meeting quality and delivery demands, adding a workerless third shift is a tantalizing possibility. It’s also a bit scary.
