The J20 Horizontal Boring Machine is equipped with a hydraulically actuated spindle carriage that moves back and forth and a steel table, vertically adjustable up to 2.5 inches.
The spindle carriage slides over two hard chrome-finished guideposts. Drilling depth, up to 6 inches precisely, is set by micro switches, while spindle advance feed speed can be set by flow control valve. For added flexibility in the boring patterns, spindle and/or clusters are belt driven and powered by 1, 1.5 or 2 HP three phase motors 220, 440 or 600 volts / 60 cycles
Belt driven spindles and fixed center clusters, as well as hold downs, are mounted on dovetail beams. Spindles can be moved to the exact position with the help of a scale fastened to the face of the dovetail beam
The J20 is available in 4, 5, 6, 8 and 10 foot widths.
