Motor Carriage: The Motor Carriage is the yellow, pivoting A-frame
structure inside the machine. Both the Router Motor and the Drill
Motor are mounted to this carriage. The forward and back carriage
motion during the machine cycle is provided by the Drive Cylinder.
Drive Cylinder: This double-acting pneumatic cylinder connected to
the Motor Carriage and the machine case, moves the carriage
through the routing and drilling phases of the cycle. When the
cylinder rod extends (moving the carriage toward the rear) the router
cuts the pocket. When the cylinder rod retracts (moving the carriage
forward) the pilot drill bores the pilot hole into the pocket.
NOTE: SQE valves are replaced by elbow fittings in models with
Serial Number 62481 and higher.
Router Stop Switch: This magnetic proximity switch is mounted on
the Router Stop Plate inside of the machine. At the full extension of
the routing stroke, the carriage interrupts this switch to signal the start
of the drilling stroke.
Drill Stop Switch: This magnetic proximity switch is mounted inside
the machine case near the Safety Buttons. At the full extension of the
drilling stroke, the carriage interrupts this switch to signal the end of
the cutting cycle. The carriage returns to the neutral position and the
clamp releases the work piece.
Control Box: The Control Box is the sheet metal enclosure
containing the electrical and pneumatic controls. Mounted in the
Control Box are the power switch and the power outlets for the
motors. Mounted on the underside of the Control Box are the air inlet,
the Pressure Regulator, the Router Speed Control valve, and the
solenoid valves.
