A blade assembly comprising compartments for cooling fluid and air.

A blade storage array is detachably mountable with a tissue log cutting saw. The saw has a cutting arm with a tool holder receptacle adapted and configured to hold a circular saw blade for the saw. The array has a plurality of storage units. Each storage unit is adapted and configured to store a circular saw blade for the saw. Each storage unit has a tool holder receptacle adapted and configured to hold a circular saw blade. Each storage unit is adapted and configured to move perpendicularly to the saw blade center axis.

What is disclosed is an improved method of sawing wood and an improved sawmill capable of producing vertical grain lumber. Vertical grain lumber is a preferred lumber for use, for example, in trim applications. The improved method and improved sawmill both utilize a track having a carriage, the carriage has a vertical blade and a horizontal blade. The vertical blade and the horizontal blade travel on the carriage down the track. The log is then rotated for another length of lumber to be cut. In a preferred embodiment the sawmill utilizes a skewer for adjusting the log. In a preferred embodiment the log is held by a lathe that can be moved. In a preferred embodiment the log is placed on a skewer before it is engaged by the lathe.

The invention relates to a chop saw for a cutting machine, having an axis of rotation (2) and comprising a circular first sawtooth disk (4) and a first carrier (3) holding the first sawtooth disk (4), wherein the first saw tooth disk (4) has a plurality of sawteeth (5) over the circumference thereof and/or on the flat surfaces thereof, and wherein the first carrier (3) is symmetrical along the axis of rotation (2), and wherein the first carrier (3) has, on a first carrier surface (7), a retaining mandrel (9) for holding the chop saw (1) in a machine chuck of the cutting machine, and wherein the first sawtooth disk (4) is positioned on a second carrier surface (8) of the first carrier (3), which faces away from the first carrier surface (7), and wherein the chop saw (1) has a second sawtooth disk (11), which is arranged parallel to the first sawtooth disk (4). According to the invention, an outside first disk diameter (DA1) of the first sawtooth disk (4) is smaller than an outside second disk diameter (DA2) of the second sawtooth disc (11), and an axial distance (A) is formed between the first sawtooth disk (4) and the second sawtooth disk (11).

A dividing groove forming device includes: a first cutter including a plurality of first rotary blades; a second cutter including a plurality of second rotary blades; a first rotation drive unit for rotationally driving the first cutter; a second rotation drive unit for rotationally driving the second cutter; a cutter support unit; and a phase adjustment unit. The cutter support unit supports the first cutter and the second cutter such that the first and second cutters are radially opposed to each other so that rotation axes of the first and second cutters are parallel to each other. The phase adjustment unit adjusts a phase of at least one of the first cutter and the second cutter such that the first rotary blades and the second rotary blades are opposed to each other in an opposing area in which the first cutter and the second cutter are opposed to each other.

A substrate cutting device includes: a first cutter including a plurality of first rotary blades; a second cutter including a plurality of second rotary blades; a first rotation drive unit for rotationally driving the first cutter; a second rotation drive unit for rotationally driving the second cutter; a cutter support unit; and a phase adjustment unit. The cutter support unit supports the first cutter and the second cutter such that the first and second cutters are radially opposed to each other so that rotation axes thereof are parallel to each other. The phase adjustment unit adjusts a phase of at least one of the first cutter and the second cutter such that each of the second rotary blades is located between two adjacent first rotary blades in an opposing area in which the first cutter and the second cutter are opposed to each other.

The present disclosure provides a side-mounted double-saw synchronous transmission apparatus, which includes a first transmission part and a second transmission part, both of which are disposed on a stationary base and can move back and forth, and is further provided with a side-mounted synchronizing device which is provided with a power shaft, where the first and second transmission parts are both in power transmission coupled with the power shaft. The power shaft can drive the first and second transmission parts to move back and forth alternately through forward and reverse rotation. The side-mounted synchronizing device is disposed on a side of the stationary base to stay away from water mist through extension of the power shaft, and an axial extension direction of the power shaft is perpendicular to a direction in which the first and second transmission parts move back and forth along an extension direction of the stationary base.

The present utility model relates to a twin saw blade cutter, improves upon the existing foundation of inner and outer saw blades, small and large output shafts, first and second gearwheels and a power gear shaft, etc., in that the small output shaft is designed with a first annular locking groove and a second annular locking groove located between the first and second gearwheels, a first locking spring which presses against a fifth bearing is mounted in the first annular locking groove, a second locking spring is mounted in the second annular locking groove, and at the same time a flexible piece which arches towards the side of the second locking spring is further sleeved on the small output shaft, the two ends of the flexible piece pressing against the second gearwheel and the second locking spring respectively. After adopting the above solution, it is possible to not only prevent outward protrusion of the small output shaft, but also prevent retraction of the small output shaft, and at the same time absorb the cumulative manufacturing tolerance of the various components and preload the small output shaft in the axial direction, thereby ensuring coincidence of the axial positions of the two shafts such that the inner saw blade has a limited amount of space for sliding movement left and right, and ensuring that there is an appropriate gap between the two saw blades at all times, such that the cutting operation may proceed smoothly and reliably.
