    I have a emco mill 50 will a 3000rpm max spindle. I need to use a 2mm cutter to mill/route lexan material. I have a feeling the spindles going to be to slow with the small cutter. Has anyone tried milling lexan? Is my spindle too slow?

    Cheers

    I've used hand held routers with 26000 rpm and single flute TCT for 2mm and that's cut fine. But I would say 300 rpm would be to slow. This might help you, scroll down about half way down the page. You'll see this

    " Computerised trimming is a fully automatic milling process. It is extremely accurate and operates horizontally as well as vertically. The use of a vacuum-operated jig avoids vibration of the part ensuring a smooth cut. Standard high speed, two sided cutting routers with tungsten carbide tips are recommended, with a cutting speed of approximately 250 m/min at 25.000/30.000 RPM at a sheet thickness of 4 mm."

    Hope this helps. Mike

    You may also find that a cutting fluid made of approx 50-50 dish detergent and water will help immensely

    Thanks guys sounds like my spindle may be too slow. Might try and get some lexan to make some test cuts before commiting to the job.
