Application
Manufacturing operations with positioned leading spindle and rotating tools require exact
synchronism with the counter spindle which then functions like a following spindle. A turret
rotating about the following spindle allows parts to be machined with different tool types. The
following diagram shows an application in which the tool is positioned parallel to the main
spindle.
