tips on CNC cutting, Upcut vs. Downcut

A customer recently asked us for some advice on cutting aluminum that had been laminated to plywood. The plywood was 3/4″ thick and the aluminum was 1/6″.  As with many composites, routing aluminum laminated wood takes a little bit more effort and care. It’d have been nice to recommend just one router bit to do the job, unfortunately this particular composite is best tackled in two stages, with two different bits.

First: Route the aluminum with a 63-600 Series tool. These tools are designed for aluminum plate or single/multi sheet aluminum.

Second: Route the wooden layer with 52-200 Series or 60-100C Series Compression Tool. The compression tool is especially helpful for routing laminated or composite wood products. It’s coated to withstand the high temperatures generated when cutting laminates.
