| 20090320657 | Turning Machine - A turning machine is provided for machining a workpiece with respect to a longitudinal axis ( | 12-31-2009 |
| 20140230617 | CONVERGENCE MACHINING APPARATUS BASED ON TURNING - Disclosed is a convergence machining apparatus based on turning in which a rotational axis of a work piece fixed by a headstock and a tailstock and a center of a width of a slide surface of a bed on which a reciprocal carriage installed with a tool is transferred while being supported are positioned at the same virtual plane, thereby preventing an offset error according to a relative displacement between the work piece and the tool during processing. | 08-21-2014 |
| 20150101466 | CONVERGENCE MACHINING APPARATUS BASED ON TURNING - Disclosed is a convergence machining apparatus based on turning in which a rotation center of a work piece to a headstock and a footstock and a slide surface of first and second beds mounted with a reciprocal carriage, the headstock, and the footstock are positioned on the same virtual line when viewed from a direction parallel with a rotation axis of the work piece, thereby preventing an offset error in processing due to a relative displacement between the work piece and a tool installed at the reciprocal carriage. | 04-16-2015 |

| 20090120250 | PRECISION ROLL TURNING LATHE - There is provided a precision roll turning lathe which can perform machining of fine grooves at a dramatically higher speed as compared to conventional roll turning lathes, thus significantly shortening time taken for machining one groove. The precision roll turning lathe includes: a bed; a headstock, mounted on the bed, having a main spindle for rotating a roll as a workpiece while holding one end of the roll by means of a chuck; a tail stock, mounted on the bed and disposed opposite the headstock, for rotatably supporting the other end of the roll; a carriage including a saddle mounted on the bed movably in the longitudinal direction of the roll, and a table mounted on the saddle movably in a direction perpendicular to the longitudinal direction of the roll; and an air slide apparatus, mounted on the table, including a guide rail extending parallel to the roll in the longitudinal direction, an air slider having a diamond tool, capable of traveling in a floating state on the guide rail, and a linear motor for driving the air slider. | 05-14-2009 |
| 20100162862 | Tripper assembly for a clamshell lathe - A tripper assembly for use in advancing a clamshell lathe tool slide including a tool for milling a portion of a workpiece such as a tube or pipe, the tool slide being operatively connected to a rotatable ring of the clamshell lathe and the tripper assembly operatively connected to a stationary ring of the clamshell lathe. The design of the tripper assembly is such that the position, engaged or disengaged, of the tripper element can be easily ascertained. | 07-01-2010 |
| 20110138976 | PRODUCTION MACHINE FOR NON-CIRCULAR WORK PIECES - A production machine for non-circular workpieces provided with a tool feed unit ( | 06-16-2011 |
| 082134000 | Electrical type | 1 |
| 20160107329 | ELECTRIC VENEER LATHE - Embodiments of an electric linear actuator may include a roller screw assembly, an electric motor coupled to the roller screw assembly, and a linear transducer operatively coupled with the roller screw assembly. The motor may be configured to drive the roller screw assembly to extend and retract another component, such as a rod. In some embodiments, the linear transducer may be configured to detect a position of the rod. The roller screw assembly may be coupled directly to the motor via a gear coupling, with the motor disposed generally in axial alignment with the roller screw assembly. Other embodiments disclosed herein include a veneer lathe carriage with electric linear actuators and corresponding apparatuses, methods, and systems. | 04-21-2016 |
| 082137000 | Slide rest | 3 |
| 20100288090 | TOOL HOLDING DEVICE FOR A FIVE-AXIS LATHE - A tool holding device is disposed between a headstock unit and a tailstock unit of a five-axis lathe, and includes a saddle driven to move longitudinally, a cross-slide riding on the saddle and driven to move transversely, a turntable platform disposed on a base mount that is disposed on the cross-slide and driven to revolve about an upright axis, and a tool post mounted on a base rest that is disposed on the turntable platform and driven to move uprightly. An indexable turret is disposed on the tool post for holding tool bits such that the five-axis lathe can perform movements about five axes to machine a workpiece so as to obtain a complicated geometric shape, thereby reducing setup time and errors and increasing production. | 11-18-2010 |
| 20160114445 | BRAKING MECHANISM AND PROCESSING DEVICE USING THE SAME - A braking mechanism includes a rack, a receiving member, a braking member, a base seat, a resetting member and an elastic member. Two ends of the resetting member abut the base seat and the receiving member, and the elastic member is positioned between the base seat and the braking member. The elastic member and the resetting member are positioned at opposite sides of the braking member. The base seat includes a first guiding portion, the braking member includes a second guiding portion and an engaging part. The second guiding portion is capable of moving along the first guiding portion under an elastic restorative force of the resetting member and the elastic member, such that the engaging part is engaged with the rack. | 04-28-2016 |
| 20160114446 | BRAKE AND PROCESSING DEVICE USING THE SAME FOR A CUTTER DEVICE IN PROCESSING APPARATUS - A processing device includes a mounting base, a cutter holder, and a brake. The brake includes a driving member, a resisting member, and an elastic member. The driving member includes a main body and a driving shaft movably placed in the main body. The driving shaft is driven to move in a straight line by the main body. One end of the driving shaft is movably coupled to the cutter holder, and another end of the driving shaft is coupled to the resisting member. The elastic member is positioned between the main body and the resisting member. The driving shaft is configured to move toward one side of the driving member adjacent to the elastic member under an elastic restoring force of the elastic member, whereby the cutter holder moves with the driving shaft toward one end of the driving member adjacent to the elastic member. | 04-28-2016 |
