摘要:
Gegenstand der Erfindung ist eine Werkzeugmaschine mit einem eine Standfläche (1) zur Aufstellung der Werkzeugmaschine auf dem Boden aufweisenden Träger (2). Diese erfüllt die Sicherheitsbestimmungen hinsichtlich der Standfestigkeit und weist gleichzeitig einen hohen Bedienkomfort auf. Das wird dadurch erreicht, daß der Träger (2) zumindest ein zusätzliches Standelement (6) aufweist, das in eine Transportstellung und in eine Sicherungsstellung bringbar ist, und daß das Standelement (6) so angeordnet und/oder ausgebildet ist, daß es in seiner Transportstellung die senkrechte Projektionsfläche der Werkzeugmaschine im wesentlichen nicht vergrößert und in seiner Sicherungsstellung die Werkzeugmaschine gegen Umkippen sichert.
摘要:
A stone slicer of slicing rough stone into stone plates having a predetermined thickness, which can improve productivity by reducing consumption of the rough stone by minimizing the thickness of a cut portion cut by a saw blade, and can reduce the treatment cost of sludge generated when the stone is sliced and prevent pollution due to the generated sludge. The stone slicer includes a base (10) on which stone is placed, four columns (22, 24, 26, 28) vertically installed at four edges of the base (10), a pair of a pair of platforms (30, 30’) installed left and right so as to be capable of simultaneously elevating along either side of the columns (22, 24, 26, 28), platform driving means (40, 40’) for elevating the platforms (30, 30’), one or more endless track type belt saws (70) each having opposite ends mounted in parallel with driving pulleys (50) and driven pulleys (60) provided at the platforms (30, 30’), and belt saw driving means (80) for driving the belt saws (70) to slice the stone placed on the base (10) to a predetermined thickness while rotating along an endless track by rotating the driving pulleys (50).

A hand-held band saw has a handle for grasping the band saw, a motor, a drive wheel driven by the motor, a driven wheel and a continuous blade disposed about the drive wheel and the driven wheel. A portion of the continuous blade is positioned in a cut zone to perform a cutting operation. A workpiece guard is spaced from the continuous blade and positioned generally between the cut zone and the handle for limiting movement of the workpiece after the cutting operation.

A hand-held band saw (10) has a handle (30) for grasping the band saw (10), a motor (16), a drive wheel (62) driven by the motor (16), a driven wheel (64) and a continuous blade (26,28) disposed about the drive wheel (62) and the driven wheel (64). A portion (106,108,110) of the continuous blade (26,28) is positioned in a cut zone (44) to perform a cutting operation. A workpiece (28) guard (14,20) is spaced from the continuous blade (26,28) and positioned generally between the cut zone (44) and the handle (30) for limiting movement of the workpiece (28) after the cutting operation.
摘要:
A gauge and frame for a portable sawmill to make wooden box culvert has a frame adapted to receive the portable sawmill, the frame including a pair of spaced guide members; each the guide member includes a worm screw member adapted to linearly move a retainer member, a holding member adapted to orient the retainer member at a desired angle, and an angle selecting member adapted to move the retainer member; a beam rotating member rotatably attached to the frame and located between the guide members, the beam rotating member including a support member adapted to hold wooden beams, and a handle member used for rotating the support member in a plurality of axes, such that wooden beams can be manipulated and held in desired orientations and thereby cut in chosen angles and shapes by a ribbon saw of the sawmill.
