4 STEPS TO SURFACING MDF SPOILBOARDS

摘要

Spoilboard, sacrificial board, bleeder board- whatever you want to call it, you've got to prepare the board for use on a CNC bed, to remove the sealer and make it porous so the vacuum will pull through it and hold down the workpiece. The goal is to remove the sealer that comes on every piece of MDF. Recipes vary, but here's one that hasn't failed me yet. 1. Start with 3/4-inch medium density fiberboard (MDF). 2. Using a 4-inch flycutter with three blades, it should be spinning at 12,000 RPM at 30 meters per minute; using a 3-inch flycutter at 12,000 RPM, run at 25 meters per minute. Overlap each cut by about 1mm.
