Radius Master Owners Manual
SYSTEM FUNCTION
Initially the die springs hold the die shoes open. When shop air is hooked to the machine it flows through
the air valve and into the return side of the cylinder. This force helps return the die shoe to the ready
(open) position at the conclusion of the machine cycle.
The complete machine cycle is initiated when the operator loads a workpiece into a die opening that
corresponds to the desired corner radius and activates the footswitch. The footswitch energizes a
solenoid mounted on the air valve. The solenoid causes the air valve to shift 80-100 PSI of shop air from
the ready side of the cylinder to the power booster which - through reduction and compression - multiplies
the force on the hydraulic side by a ratio of 16 to 1. Hydraulic pressure then actuates the cylinder, which
pulls the die shoe and blade through the workpiece. Force is maintained until the operator releases the
footswitch. When the footswitch is released, the solenoid is de-energized and shop air flows back to the
return side of the cylinder, raising the die shoe and blade to their ready position.
