This is the newest machine in the great line of Eckold Kraftformers. The new KF340 has an adjustable operating speed from 250 to 550 strokes per minute. We have found the lower speeds to be ideal for shrinking and straightening, while the higher speeds are best suited for stretching, doming and planishing. The unit has ample power to work steel up to .118" and aluminum to .157" thicknesses. The foot pedal adjusts the jaw pressure and also has an emergency stop function. As with all Eckold machines, the new KF340 has a quick change jaw feature and accepts all the jaws and accessories used with the KF324 and KF330 machines.
