MATERIAL SELECTION

CAUTION:
processed through the machine are NOT potentially hazardous to operator or
personnel working nearby.
When selecting materials keep these instructions in mind:
• Material must be clean and dry. (without oil)
• Material should have a smooth surface, so it processes easily.
• Dimensional properties of material must be consistent and not exceed the machine capacity
values.
• Chemical structure of material must be consistent.
• Buy certificated steel from the same vendor when possible.

HYDRAULIC SYSTEM

Refer to the hydraulic schematic for additional detail and to the components being discussed.
CAUTION:
footwear, and leather gloves to protect from burrs and sharp edges.

Cutting Stroke

When the pump is started, press the footswitch. The coil YA2 solenoid valve (No.13) is
energized and the spool moves to close the P port.
Oil is directed to the clamping cylinders. The clamping cylinders will be pressurized and lower to
clamp and hold the material.
At the same time, pressurized oil will divide to enter the top chamber of the left cylinder.
With oil forcing the left cylinder piston to move down, oil from the left cylinder lower chamber is
forced across to the upper chamber of the right cylinder. This also forces the piston down and
the oil from the lower chamber of the right cylinder will flow into the accumulator (No. 20).
Because the volume of the lower chamber of the left cylinder is nearly equal to that of the upper
chamber of the right cylinder, a serial synchronous circuit is formed which moves the cutting
beam downward evenly.
It must be determined by the customer that materials being
