Hi
I need to produce some high spec cabinets with a box joint on the ends of large sheets of 10mm thick aluminium 6082 T6 tooling plate , the sheet sizes range from 400 w x 2500mm long to 800 w x 3000mm long . I have attached a picture of a sample cabinet we produced which was milled on a Bridgeport type bed mill layed flat ( as the sheet is too wide to stand up ) with 90 degree head to produce the slots .The client loves what we have done & we now have to produce loads of cabinets so we need a better & quicker way to produce these joints. The joints themselves need to be very precise i.e maximum of 0.1 mm clearance in the fit , I believe the sample we made was 0.05mm clearance & we used grooved pins inserted to give the actual strength in the joint which is we would look to do in the new cabinets as well.
I was wondering if there was either a better technique or more suitable machine to do these on ( maybe even an aluminium extrusion processing machine ?).All faces need to be brushed finish which we can get the flat faces done by a sub-contractor after they are notched but the ends & sides would need to be done by ourselves prior to sending to polishers. For this reason I have steered away from waterjet as it would leave a fluffy edge & I would be worried that the box joint fix might not be accurate enough.
Any help would be greatly appreciated
