When using a rosary cutter, first secure the wood firmly, adjust the spindle speed to 15,000–24,000 rpm, and feed slowly and evenly. The cutting should be performed in layers with a progressive approach to avoid deep single cuts that may cause chipping or tool breakage. Leave a 0.2–0.3 mm allowance for rough machining, and finally perform fine finishing to ensure the beads are smooth and round.
During machining, promptly remove chips. Wood can be cooled with air to prevent blade burning or chip adhesion. Keep the tool overhang as short as possible to enhance rigidity and reduce vibration. Clean the tool holder and chuck when changing tools, and apply moderate tightening force. Strictly avoid cutting hardwood or metal beyond specifications to prevent tool damage. Clean wood chips promptly after use, store them properly to protect the blade, and extend the tool's service life.
