Abstract: A cutting tool for truncating elongated structural members has a frame with a pair of parallel siderails connected at a first end by a support plate and at a second end by a removable end gate, the frame having an open center adapted to receive the structural member therethrough. The truncating is performed by a fixed penetrating cutting edge on an end gate and a driven penetrating blade slidably disposed within the frame to advance towards the end gate. The end gate has two integral penetrating cutting edges pointing in opposite directions. The driven penetrating blade and the fixed penetrating cutting edge may have concave cutting edges relative to one another and configured to be adjacent to one another along the travel of the driven penetrating blade. Alternately, an end gate second cutting edge may be directed to the opening within the frame and have a piercing V-shaped cutting edge.

Abstract: A pulverizer may have such features as an ability to detect wrapping as well as possibly deter wrapping. A processor may also adjust the speed of rotation of the arms within the pulverizer and/or the speed of feed of input for various considerations. In fact the rotation direction may be reversed for at least brief periods of time in an effort to remove wrapped material. Vibration may also be sensed and efforts to prevent damage may be instigated by a processor.

Abstract: A power tool includes a rotatable support arrangement for supporting at least one cutting disc. An upper shroud member and a lower shroud member cooperate to define a volume in which the at least one cutting disc can be supported. The rotatable support arrangement can be coupled to the upper shroud member such that movement of the upper shroud member towards the lower shroud member causes the cutting disc to protrude through an opening in the lower shroud member. A biasing member urges the upper shroud member and the lower shroud member away from each other. A limiting mechanism limits the range of movement of the upper shroud member relative to the lower shroud member under action of the biasing member. The limiting mechanism can be disengaged by opening the upper shroud member via at least one hinge coupling.

Abstract: A controller of a cutting apparatus obtains cutting data and specifies a pressure value corresponding to pressure to be applied to an attaching portion by a pressure changer during cutting processing for cutting a workpiece using a cutting blade based on the cutting data and a target range defining target positions of the attaching portion in a fifth direction. While causing the pressure changer to apply, to the attaching portion, the pressure corresponding to the specified pressure value, the controller executes the cutting processing by controlling a first moving mechanism and obtains the position of the attaching portion in the fifth direction. If the obtained position of the attaching portion is out of the target range, the controller changes the pressure value to another value and executes the cutting processing while causing the pressure changer to apply, to the attaching portion, the pressure corresponding to the other value.
