Abstract:

This invention pertains to a tool attachment for milling machines which converts the rotary motion of the spindle of a milling machine to a reciprocating motion of tool bits in the tool attachment. This attachment permits the precise cutting or broaching of specified shapes in pieces of metal and other nonferrous materials by utilization of a dial indicator to indicate precise positioning of the bits.
