All drilling and set-up controls are logically arranged on the control panel located at the drillers’ station. And the location of all primary controls is the same on all CME drill models so operators can move from one machine to another with confidence. The most commonly used functions, such as the feed, hydraulic hoist, and sliding base levers are staggered for easier identification and operation. Also, a lock out position for the clutch lever to prevent accidental engagement.
The hydraulic feed and retract system delivers a retract force of 30,000 pounds (13,607 kg) and a down pressure of 20,000 pounds (9,071 kg). It features a 72-inch (183 cm) stroke mechanism with twin hydraulic cylinders aligned with the drill spindle for effective pulldown and retract forces. The feed system includes dual controls for manual operation and detent settings, achieving retract rates up to 84 feet (25 m) per minute for quick tool changes. The detent controls allow precise feed rate and pressure, beneficial for core drilling and applications requiring accurate feed control. The two control systems operate independently, enabling manual controls without affecting detent settings.
Our emergency spindle brake can stop rotation in less than a revolution. This system is activated by two conveniently located push button switches as well as strategically located multi-directional wobble switches.
