The Coupler Saw will cut to length while cutting internal groves for o-ring designs. After each cut, the part is removed and the pipe section would be repositioned in the saw for the next cut. The composite wound parts are placed onto this machine and secured into place by placement of lock down roller supports. These supports are adjustable to accommodate sizes of up to 2M (6.5-ft.) in diameter. Each individual saw has a dust collection system. The dust from the cutting action is collected at one central location to ease the maintenance and operation of this machine.
