20080202306 | Workpiece Cutting Method and Band-Saw Machine - A workpiece cutting method utilizing a band-saw machine, includes the following steps of: guiding tooth tips of an endless band-saw blade ( | 08-28-2008 |
20090007437 | METHOD OF CUTTING OFF WORKPIECE USING BAND SAW MACHINE AS WELL AS BAND SAW MACHINE - A method of cutting a workpiece using an endless band saw blade and a band saw machine are provided. The method includes suspending the endless band saw blade between a driving wheel and a driven wheel such that the workpiece may be cut by the endless band saw blade, applying at least a first pulse and a second pulse to a first motor rotating the driving wheel and a second motor rotating the driven wheel, respectively, wherein the pulses have phases opposite to each other, and cutting the workpiece. The band saw machine includes an endless band saw blade suspended between a driving wheel having a first motor and a driven wheel having a second motor. The band saw machine further includes a pulse applying module that applies at least a first pulse and a second pulse to the first motor and the second motor, respectively, wherein the pulses have phases opposite to each. | 01-08-2009 |
20090013840 | METHOD OF CUTTING OFF WORKPIECE USING BAND SAW MACHINE AS WELL AS BAND SAW MACHINE - In a cutting-off method, when a workpiece is to be cut off by use of an endless band saw blade suspended between a driving wheel and a driven wheel, the workpiece is cut off by imparting to the driving wheel a forced oscillation so that a phase of an oscillation of the driving wheel along its rotational direction is substantially inverted with respect to a phase of an oscillation of the driven wheel along its rotational direction. In addition, pulses can be applied to a driving motor for rotationally driving the driving wheel in order to cause the driving wheel to oscillate along its rotational direction. | 01-15-2009 |
20090173197 | SAWING MACHINE, CUTTING-OFF METHOD, AND METHOD OF REDUCING NOISE - A band saw machine includes a driving wheel and a driven wheel around which an endless band saw blade is wound. At least one of the driving wheel and the driven wheel is directly connected to an output shaft of a control motor. The output shaft of the control motor is arranged in a cylindrical bearing unit installed on a motor base supporting the control motor. The driving wheel is rotatably supported by the bearing unit. | 07-09-2009 |
20100175530 | WORKPIECE CUTTING METHOD AND BAND SAW MACHINE - A workpiece cutting method utilizing a band-saw machine, includes the following steps of: guiding tooth tips of an endless band-saw blade provided on the band-saw machine in a direction of a workpiece by a band-saw blade guiding apparatus; and applying vibrations to the band-saw blade in a cutting direction to the workpiece so as to perform cutting of the workpiece by a vibration applying unit provided on the band-saw blade guiding apparatus. | 07-15-2010 |
20100175531 | WORKPIECE CUTTING METHOD AND BAND-SAW MACHINE - A workpiece cutting method utilizing a band-saw machine, includes the following steps of: guiding tooth tips of an endless band-saw blade provided on the band-saw machine in a direction of a workpiece by a band-saw blade guiding apparatus; and applying vibrations to the band-saw blade in a cutting direction to the workpiece so as to perform cutting of the workpiece by a vibration applying unit provided on the band-saw blade guiding apparatus. | 07-15-2010 |
20120180611 | MAIN BODY VISE DEVICE IN BAND SAW MACHINE - Disclosed is a main body vise device ( | 07-19-2012 |
20120204700 | METHOD OF HOLDING BAND SAW BLADE BY MEANS OF BAND SAW BLADE GUIDE DEVICE, AS WELL AS BAND SAW BLADE GUIDE DEVICE - In the process of holding a non-toothed section of a band saw blade between a fixed insertion block and a movable insertion block included in a band saw blade guide device, the movable insertion block is moved while a return allowing unit included in an insertion block moving unit is held in a returnable state, the insertion block moving unit configured to move the movable insertion block toward the fixed insertion block. The band saw blade is firmly held between the fixed insertion block and the movable insertion block. Thereafter, the entirety of the insertion block moving unit, including the return allowing unit, is fixed in an immovable state by a mechanical fixing unit. | 08-16-2012 |
20130152751 | METHOD OF CUTTING OFF WORKPIECE USING BAND SAW MACHINE AS WELL AS BAND SAW MACHINE - A cutting-off method whereby is disclosed, whereby when a workpiece is intended to be cut off by use of an endless band saw blade suspended between a driving wheel and a driven wheel, the workpiece is cut off by imparting to the driving wheel a forced oscillation so that a phase of a longitudinal oscillation which occurs to the bandsaw blade near the driving wheel is substantially inverted to a phase of a longitudinal oscillation which occurs to the bandsaw blade near the driven wheel. | 06-20-2013 |
20140360324 | BAND SAW MACHINE AND CONTROL METHOD OF BAND SAW MACHINE - A feed vise is configured to position a work material on a pass line. A band saw blade has zero twisting, and is configured to cut the work material into a length smaller than a diameter of a driving wheel. A product discharge vise has product discharge vise jaws. The product discharge vise jaws clamp the work material, and the band saw blade is configured to be lowered and cut the work material. After the cutting is completed, the product discharge vise is configured to discharge a product, which is obtained by cutting the work material, below the pass line, while the product discharge vise clamps the product. | 12-11-2014 |
