Im using a standard 2.2kw chineese spindle, spinning at top wack 2200rpm? Ive checked its spinning in the right direction. all Im cutting is 3mm ply.
Matt As Gerry has said drop your rpm down and feed rate up. 2500mm/min seems slow to me. Gwizard indicates with a 6mm 2 flute carbide slot cutting 4mm DOC 18450 rpm 7790 mm/min feed. rate
