Abstract
Abstract Machine tool apparatus including workpiece supporting means for supporting and rotating a workpiece, and a tool holder movable in parallel and transverse directions with respect to the rotary axis of the workpiece supporting means. A cutting or grinding tool is mounted on the tool holder for selective rotation about a tool axis, the tool having a workpiece engaging portion located on the tool axis so that the tool can extend perpendicularly to the surface of a workpiece regardless of the contour of the workpiece as the tool holder moves the tool along the length of the workpiece.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
228 words
Machine tool apparatus comprising: workpiece supporting means for supporting and rotating a workpiece; a tool holder movable in parallel and transverse directions with respect to the rotary axis of said workpiece supporting means; a tool having a workpiece engaging portion; mounting means mounting said tool on said t tool holder for selective rotation about a tool axis perpendicular to the rotary axis of said workpiece supporting means, said workpiece engaging portion of said tool being located on said tool axis; said mounting means including a head portion secured to said tool holder, an outer plate member secured to said head portion in spaced relationship with said tool holder and an inner plate member secured to said tool holder in spaced relationship with said outer plate member, said inner and outer plate members being formed on their opposed faces with shoulders defining a circular track having its geometric center located on said tool axis, a circular slide member received between said plate members and mounted on said circular track, said tool being secured to said slide member, a circular toothed sector secured to said slide member in concentric relationship therewith, a recess formed in said head portion, and a worm gear extending into said recess and meshed with said toothed sector operable upon rotation to cause said slide member and hence said tool to rotate about said tool axis.
