Major Automotive Computer Manufacturer

PROBLEM:

To automatically receive prefabricated computer frames directly from the die casting line, drill and tap ten (10) separate through and blind metric holes, in sizes from 19mm to 39mm, in both the vertical and horizontal planes.

SOLUTION:

Design and fabricate a special linear machining system with twelve (12) work stations for the purpose of producing finished machined computer housings at the rate of 10 per minute.

SPECIAL CONSIDERATIONS:

Provide inspection stations to determine the presence and position of the die cast computer frame, then not drill if improperly positioned or missing.
Drill four (4) holes simultaneously in the frame's horizontal plane, index to the next station and tap them simultaneously.
Index to the next station and drill two (2) more holes simultaneously in the same plane, index to the next station and tap them simultaneously.
Index to the next station and gage.
Index to the next station and rotate the frame.
Index to the next station and drill four (4) more holes simultaneously in the frame's vertical plane, index to the next station and tap them simultaneously.
Index to the next station and gage.
Index to the next station and unload.

EQUIPMENT FURNISHED:

Intermittent motion machining system with twelve (12) stations.
Ten (10) drilling heads.
Ten (10) tapping heads.
Sensors for probing frame presence, positioning, work in processs and drilled holes prior to tapping.
Pneumatic Pick and Place System for unloading finished computer housings.
