Abstract
An apparatus for removing excess material, such as spur bits or sprues, from workpieces, provided with a support surface having a guide channel therein for receiving excess material therein for guiding to a rotatably driven removal tool having a peripheral cutting or grinding segment submerged in a slot in the support surface and which is mounted for selective movements in parallel as well as normal to its rotational axis to allow adjustments to compensate for changes in the size or kind of tool as a result of wear or replacement. While not so limited in its application, the apparatus is of particular use for removing spur bits or sprues from workpieces.

An apparatus for removing excess material from a workpiece, comprising:
- substantially planar workpiece support surface means having upper and lower sides with an opening penetrating therethrough and extending in predetermined direction;
- guide means in said workpiece support surface means extending into said opening in a direction substantially normal to said predetermined direction, said guide means being adapted to receive said excess material for movement relative to said opening;
- and
- rotatably driveable tool means of substantially circular configuration mounted below said workpiece support surface means and comprising a peripheral material removal segment extending into said opening to a point below said upper side of said workpiece support surface means and intersecting said guide means.
