Abstract: A side milling cutter arbor for mounting a selected milling cutter on a vertical milling machine that includes first, second and third interconnected members. The first member has a generally cylindrical body portion and a reduced diameter shank portion connected to the body portion. The body portion is provided with a longitudinal bore having a first portion having a key way and a second portion, the second portion being generally rectangular in cross-section. The second member has a flange portion, an intermediate portion having a key receivable within the key way and an end portion, the end portion being generally rectangular in cross-section and being closely receivable within the second portion of the longitudinal bore of the first member. The third member functions to removably interconnect the first and second members.

Abstract: A stop device that can be readily interconnected with a variety of commercially available vertical milling machines to precisely control the vertical travel of the quill mechanism of the milling machine. The bolt-on stop device of the invention includes three vertically adjustable stop mechanisms, each of which includes adjustable slide elements that can be horizontally extended or retracted relative to the quill mehanism of the milling machine. When extended the slide element moves directly into the path of vertical travel of a follower member, or depth indicator, provided on the quill mechanism of the machine. When retracted, the slide will clear the follower member of the quill mechanism so as to enable its engagement with the next adjacent stop or slide element of the device.
