Pipecutter Cutting copper pipe with a close quarters tubing cutter. A pipecutter is a type of tool used to cut pipe. Depending on the metal of the pipe, a pipecutter can often provide a faster, cleaner and more convenient way of cutting pipe than using a hacksaw. There are two types of pipe cutters.
Metal burr extending beyond the edge of the cut piece, view on the cut face (top) and from the bottom (bottom) A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process. [1] It is usually an unwanted piece of material and is removed with a deburring tool in a process called deburring.
To achieve optimal surface speed and cutting conditions, burrs are rapidly rotated at high speeds, often in the range of thousands or tens of thousands of RPM, which is typically the maximum speed supported by a given spindle. The cutters depicted in the image, being made of tungsten carbide, can withstand and operate at these elevated speeds.
These sleeves are a tool used to hold machine cutting tools or holders in the spindles of machines such as a drill or milling machine. The reamer shown is a finishing reamer. A roughing reamer would have serrations along the flutes to break up the thicker chips produced by the heavier cutting action used for it.
Hot cutting is performed by means of a thermal torch (plasma or oxyfuel) and is mounted to the last axis of a multi-axis machine.The axes of the multi-axis machine are powered by electric motors and are synchronized to create a path for the torch and pipe that yield a desired profile.
After compression, the part shears for about 10% of the part thickness, and then fractures free of the strip or sheet. This fracturing produces a raised, jagged edge which is called a "burr". Burrs are typically removed by tumbling in a secondary process. Burr height can be used as an important indicator of tool wear.
