Patent ID: 7013774

Claim:
A tool adapted to be mounted on a screw machine, comprising: an adapter plate adapted to be mounted on said screw machine for controlled movement toward and away from said workpiece; a tool block slidably mounted on said adapter plate for relative movement relative thereto along a first axis and adapted to be selectively locked to said adapter plate at a desired position along said first axis; a slide body mounted on said tool block for rotation relative thereto about a second axis, said slide body also having a shaft coincident with said second axis; an adjustment mechanism acting between said slide body and said tool block for controllably varying the angular position of said slide body relative to said tool block; and a head slidably mounted on said slide body for movement relative thereto along a third axis, said head having a roller and having a cutting tool spaced from said roller, said roller and cutting tool being adapted to selectively engage said workpiece when said tool is moved toward said workpiece to remove material therefrom; whereby said head may move relative to said tool block along said third axis such that said roller and cutting tool will both contact said workpiece when said tool is moved toward said workpiece.
