Abstract:
A planing machine comprising:a base having two opposing sides, and a plurality of upstanding posts extending upward from said base at said sides;an upper carriage having two opposing sides mounted movably on said upstanding posts and slidable along said posts to move upward or downward;a pair of screw rods extending upward from said sides of said base, respectively, and passing through said upper carriage;moving means associated with said screw rods for moving upward and downward said upper carriage along said posts so as to adjust a gap between said upper carriage and said base;a cutter unit disposed on said upper carriage and including a shaft having two opposite ends for mounting rotatably on said upper carriage, a cutter seat which extends axially and angularly about said shaft between said opposite ends of said shaft and which has at least one axially extending cutter receiving groove with a groove bottom, at least one cutting element mounted inside said cutter receiving groove and having two axially opposing ends, and at least one cutting edge extending between said axially opposing ends, a press member disposed axially in said cutter receiving groove to press said cutting element against said cutter seat, and a pair of positioning members mounted on said cutter seat adjacent to said axially opposing ends of said cutting element, said positioning members having recessed tongue rest faces which are aligned axially with said cutter receiving groove, said cutting element further having two opposing tongues to project axially and outwardly from said axially opposing ends so as to be seated on said recessed tongue rest faces of said positioning members, said recessed tongue rest faces being formed at the same level relative to said groove bottom, thereby orienting said cutting element relative to said cutter seat; andindicator means mounted on said upper carriage and adapted to indicate thickness to be removed from a workpiece by said cutter unit, said indicator means including a pointer mounted movably on said upper carriage, and a workpiece contact element mounted movably on said upper carriage in association with said pointer so as to move said pointer when said workpiece contact element is moved by the workpiece introduced below said upper carriage.
