    摘要： A cutting apparatus for columnar items such as metal pipes has a base frame that supports a movable cutting blade. At least one blade actuator is disposed between the blade and the frame to drive the blade back and forth between retracted and extended positions. First and second arms are pivotably connected to the frame and moveable between disengaged and engaged positions. An arm actuator is associated with each arm and drives each arm between the disengaged and engaged positions. A segmented collar engages the entire circumference of the columnar item being cut. The blade is supported by the frame and the arms during the cutting process while the collar supports the material of the columnar item adjacent the cut.

    摘要： A pipe cutting apparatus having a frame and first and second pipe support arms. The pipe support arms are pivotally attached to the frame. First and second pipe support members on the first and second arms together with a third pipe support member securely grip the pipe at substantially equally circumferentially spaced locations. A camming member is used to place the first and second pipe support arms in predefined locations for holding differently sized pipes. An linkage assembly causes the third pipe support member to biasingly engage the pipe. A two-part tool shield is provided together with a depth adjusting assembly for facilitating the cutting and beveling of the pipe. A power transmission assembly transfers power from a motor on the frame to a tool located on a pivoting arm. The frame may be manufactured using an adhesive filler material for enhancing the rigidity, strength and accuracy of the components.
