With Pacif ic's hydraulic PRESS BRAKE PRESS BRAKE J-Series, you get "bonus-bending capacity" at no additional cost. STROKE AruM SPEED AD-JI"BSTMENTS ALTOW FAST SET-UPS Fast set-up is a key to high production. The J-Series' con- trols for stroke and speed adjustment greatly simplify and shorten the set-up procedure. Stroke length settings and speed change settings can be adjusted instantly by means of simplified slide-type controls con- veniently mounted on the right end of the ram. The micrometer type bottom stroke setting is adjustable to within.001". The top slroke setting is completely adjustable to allow short, high speed operation. A portable electric footswitch, in conjunction with a mode selector switch, enables the operator to choose between four types of ram control for set-up or for production runs: 1. Continuous Run Depressing the footswitch will move the ram down until the depth limit switch is contacted. The ram will then return auto- matically to the top of the stroke and continue to "cycle" as long as the footswitch is depressed. Releasing the footswitch at any point in the stroke will allow the ram to reverse and return to the iop position and stop until the footswitch is again actuated. 2. Single Stroke Control Ram will operate in the same manner as "Continuous Run", except that ram will stop at the top of the stroke. The ram will not repeat until footswitch is again actuated. T_I- 3. Jog Control (inching) Depressing the footswitch will move the ram down, however the ram will hold position when the footswitch is released. This allows "jogging" during the downstroke as an aid when bending to a line,or lay-out work. When the depth limit is reached, the ram TURN lo towER will then automatically return to the top position. UP t LEFT IND 4. Set-Up Control (inching within .001" increments) Depressing the lootswitch will move the ram down. The ram J8$')i*r '.?,iiliB will hold position when the fbotswitch is released (similar to Jog t48 Control), except that the ram will stop at the bottom of the stroke and not return automatically. Stroke depth adjustments can then be made in very small increments of .001" until the part is bent to the proper angle. This type of control is invaluable in set-up & operations.
