A cutting machine having a first wheel pair and an opposite second wheel pair, an first vertical wheel, an opposite second vertical wheel, a first drive wheel, a second opposite drive wheel, and a single cutting blade, the first vertical and the second vertical wheels being configured to travel simultaneously and in a same horizontal direction, the first and the second wheel pairs being configured to travel simultaneously and in a same vertical direction, the first wheel pair having a first slanted wheel and the second wheel pair having a second slanted wheel, the single cutting blade being routed over all wheels such that at any moment during a travel of the single cutting blade while driven by the first and second drive wheels, a vertical blade portion extends between and can travel horizontally with the first vertical wheel and the second vertical wheel during vertical cutting and a horizontal blade portion extends between and can travel vertically with the first and second wheel pairs during horizontal cutting, wherein the slant of the first slanted wheel and the slant of the second slanted wheel prevents intersection of the horizontal blade portion and the vertical blade portion.

A chain saw has a fluid pump. The fluid pump has a pump rod, a pump core assembly defining a pumping channel, and a pump body. The pump core assembly has an inner pump core and an outer pump core. The pumping channel is formed at least by a first hole defined in the inner pump core and a second hole defined in the outer pump core and the first hole is in communication with the inlet and the outlet. The pump rod is arranged to do a straight reciprocating motion in the pumping channel along a first axis so as to force fluid to flow from the inlet to the outlet by passing through the first hole.

A saw with a monitoring and safety system that utilizes vision and sensors designed to provide user feedback on safety and training. The saw having a wheel formed of an anodized main body with a non-anodized surface extending along the circumference of the groove of the wheel. The saw having low inertial energy design to stop the blade without mechanically grabbing the blade assuring multiple points of safety detection and triggering. The saw having an automatic guard to protect the user from slipping and hitting the blade even when the saw is not running. The saw being connected to a cloud based system that enables a safer ecosystem and cross statistic sharing of safety parameters.

A band saw including a frame, at least two, spaced apart, rotatable wheels supported by the frame, a blade looped around the wheels, where rotation of at least one wheel causes the blade to move around the wheels, a detection system adapted to detect a dangerous condition between a person and the blade, and a reaction system configured to engage and stop the blade within 10 milliseconds after detection of the dangerous condition is disclosed. The reaction system may be configured to cut and grip the blade.

A bandsaw assembly for cutting large diameter workpieces such as turbine rotors, heat exchangers or shafts at a plant or factory and a method of using the same is disclosed. The assembly includes a frame; ground-engaging wheels or a track provided on the frame; a plurality of spaced apart towers extending vertically upwardly from the frame; a rotatable drive wheel mounted on each tower, said drive wheel being horizontally oriented and presenting a vertically oriented circumferential surface; a motor operatively engaged with one or more of the drive wheels; and a bandsaw blade passing around the wheels and being in contact with the circumferential surfaces thereof; said blade being selectively driven by the drive wheels. The towers are variable in length to raise or lower the blade. The assembly is reduced in width for transportation or storage and increased in width for operation.

A bandsaw makes simultaneous, spaced-apart cuts in hard or soft materials with a single bandsaw blade. The invention is ideally suited to cutting spaced-apart parallel surfaces to form support blocks, however, different embodiment may be controlled or programmed to make parallel or non-parallel cuts at varying angles. The single bandsaw blade rides on circular wheels on both sides of a gap or passageway, such that a first portion of the blade crosses the passage along a first, upper path, and a second portion of the bandsaw blade crosses the passage along a second, lower path. A table moves the material through the passage, whereupon the material is simultaneously cut along two planes corresponding to the upper and lower paths of the bandsaw blade. A preferred embodiment includes a first set of upper and lower wheels on one side of the passage, and a second set of upper and lower wheels on an opposing side of the passage.
