摘要： A feed control for a horizontal bandsaw machine has a hydraulic motor assembly which includes a piston dividing a hydraulic cylinder into upper and lower chambers. The cylinder is pivotally secured to the base of the machine, and the piston is pivotally secured to the saw head of the machine by an elongated piston rod. Hydraulic fluid is simultaneously introduced into one end of the motor assembly and withdrawn from the other end to positively regulate the position of the piston within the cylinder. A first pressure control device regulates the hydraulic pressure in the upper chamber of the motor assembly, and a second pressure control device regulates the hydraulic pressure in the lower chamber of the motor assembly. By regulating the pressure differential between the upper and the lower chambers, the rate of movement of the piston, and thus of the saw head, can be precisely regulated and thus optimized to insure cutting accuracy and minimize wear on the saw blade.
