Dedicated Drill & Tap Machine
|
|
Parts are presented to the drill & tap machine by means of a free part transfer supply conveyor. The robot transfers parts to the drill/tap fixture. The drill/tap stations consists of two opposed twelve spindle fixed center heads mounted on hardened and ground box way slides. The machining slides and the drill/tap head RPM are CNC controlled. The spindles utilize quick change tooling for accuracy and allows for presetting the length of the tools offline. After the machining operations are complete the robot transfers the parts from the drill/tap fixture to the exit conveyor. The parts proceed on the conveyor to thread inspection where they are located and checked utilizing a General Inspection Unit. The reject station removes bad parts from the machine. The parts travel on the conveyor to a pin stamp unit where they are marked with the Julian date. The parts travel to the next station for a rust preventative application followed by part blow off that removes excess fluid.
