The unique Jiffy-Drill is most commonly rotated by a compact, high torque, low inertia hydraulic motor. Several units can be mounted close together, on 3-5/16" centers (with feed ports located on the bottom). Other drive options and mounting center lines are available.
The Jiffy-Drill is connected by a pair of hoses to a hydraulic power unit. The power unit must be capable of supplying pressure (PSI) and flow (GPM) for the size hydraulic motor on the Jiffy-Drill. Flow and Pressure are determined by the RPM and torque required to drill the material and the size of the hole being drilled. The power unit should have a double solenoid valve for control of the Jiffy-Drill. Contact the factory or your local distributor for proper sizing and pricing.
The drilling cycle is started with an electrical signal to one solenoid of a double solenoid valve. The signal may originate from a push button, or from a sequence on an automatic machine control. A forward limit switch mounted in the Jiffy-Drill provides a signal for reversal when proper depth has been reached. A rear limit switch stops the tap when the retracted position has been reached. Both these stop positions are adjustable.
Care must be taken when wiring the Jiffy-Drill unit. Incorrect wiring may inhibit proper start and stop signals to be transmitted to the control unit and cause damage to the unit.
