WhatsApp: +86 18838072829High feed mills take advantage of and exploit a concept known as axial chip thinning. This is a geometrical anomaly that occurs because of the milling cutter having a lead angle less than 90 deg. Axial chip thinning shows us that while the lead angle of the milling tool becomes lower, the actual chip thickness is less than the advance per tooth.
