High Speed Keyway Milling Attachment

With the work spindles stopped, keyways can be cut along the axis of the work, using a keyway milling attachment. Woodruff keys can be plunge cut, or with a profile guide, contours can be milled along the axis of the work. Keyway milling attachments can be mounted in any position. However, a cross working position as well as a tool spindle position may be required to actuate the milling attachment. The outer spindle is held stationary while the inner spindle is driven by the center drive. This attachment is available with a high speed milling head providing a cutter speed 1.56 times (42-54 gears) that of the work spindles, and a low speed milling head with the cutter running the same speed as the work spindles.
