This video shows PBLT-60 being cut by router bit manufacturer LMT Onsrud on their CR Onsrud 98HD18 3-axis CNC router. Endmill is a 52-638 Double Flute Solid Carbide Upcut Spiral O Flute @ 18,000 RPM. Feed: 180 – 420 IPM.
Take note of the amount of chips and no dust. The right CNC router bit, combined with the correct speed and feed will achieve this affect.
Big thanks to Fred and Gary at LMT Onsrud for putting this video together! Be sure to check out the excellent guide they offer for choosing the right bit for the right material.
