Abstract
A rotary table saw for sectioning dental models having a housing with a base portion and a working table mounted on the base portion. The working table is controllably depressible so as to be moved upward and downward with respect to the base. The motor housed in the base drives a rotary blade oriented in a vertical direction. A slit in the work table permits the blade to emerge therethrough as the work table is depressed. The vacuum outlet is placed in flow communication with the surface of the work table during depression of the work table to remove saw dust from the work table. The dental model is placed on the work table with the blade hidden beneath the work table. The work table is depressed to permit emerging of the rotary blade cutting from the underside of the dental model.
Claims9
A rotary table saw for sectioning dental models, comprising:
- a housing having a base portion, a motor housed in the base portion for driving a rotary blade oriented in a vertical plane, a controllable depressible horizontal work table mounted on the base portion covering the blade for freely supporting a dental model on its surface, control means responsive to the downward application of pressure on the work table for lowering the work table by a distance corresponding to the amount of pressure applied, a slit in said work table for progressively exposing said rotary blade through the work table as the work table is depressed for controlled feeding of the blade as the blade cuts upwardly through the underside of the dental model, and a vacuum outlet coupled to the base portion, the vacuum outlet being placed in flow communication with the surface of the work table during depression of the work table and transverse to the plane of the blade to remove the saw dust from the work table.
