It can also grind the back angle of the milling cutter, the polishing edge, and the edge angle of the end face. The air bearing is based on the principle of air floatation, and the main shaft is suspended after air pressure is applied. It is light and free, with almost no friction. The spindle is equipped with 5C spindle as standard, which can repair and grind straight shank milling cutter φ 2- φ 25. Maximum grindability of tools such as cutter head and three edge face φ 245, with a length of 260mm. The spindle can be replaced with a Morse type 4 # spindle hole. If other accessories are selected, the ball cutter, three side milling cutter, reamer, turning tool, carving cutter, etc. can be grinded.
