ABSTRACT:
A thread sawing device comprising a frame carrying thread guide cylinders and having a thread trained about the thread guide cylinders. A support is provided for a part to be sawed, and the thread and support are movable toward and away from each other to saw the part supported by the support. The relative position of the cylinders and the part to be sawed is detected, and responsive to that detection, the temperature of a portion of the device is changed so as to cause that portion to undergo thermal expansion or contraction, so as to maintain the desired relative position constant in a direction transverse to the direction in which the thread and the support move toward and away from each other to saw the part to be sawed. The portion of the device whose temperature is changed is one of the cylinders, or the support. A heat exchange fluid is circulated through that portion and a control for the temperature of the heat exchange fluid is provided, which is a fluid heater and a fluid cooler, and a valve for selectively sending the fluid through either the heater or the cooler.
