Since it's introduction in 1962 the auto feed drilling and tapping system (AFD) has proved it's superiority on thousands of industrial applications.

The AFD system can be built into simple semi-automatic as well as highly complicated transfer line machines using the basic drilling or tapping units and a range of clamps. Controls built into the head of the tool plus simplified circuitry enable the equipment to become fully automatic.

Emphasizing it's versatility the AFD installation can be stripped down and the basic units used again in other machines when production requirements change.

The AFD system can be used individually, or in combination with any number of drills or tappers.

It's control head is unique. An air signal starts and controls the drilling or tapping cycle. An air signal is also developed during the cycle which can be utilized, with suitable circuitry, to supply pilot air to actuate other drills, indexing tables, or clamping devices as well as providing a cycle completion signal.

Only one main air supply is required and this can be actuated by a manual start button, or remotely by an air signal to a pilot operated valve in the control head. A relatively small pilot valve can be used simultaneously to start a number of motors since the main air supply to the motor does not have to pass through it. Completely automatic valving within the head provides the unit with independent cycling capability. Once started, the tool can rapidly advance to a predetermined point, perform it's work function, retract to it's original position and shut off. Rotation of the drill during return cycle ensures the ease of withdrawal and chip removal.
