When using a rosary cutter, first secure the wood firmly, adjust the spindle speed to 15,000–24,000 rpm, and maintain a slow and steady feed rate. The cutting process should be performed in layers with progressive depth to avoid deep single cuts that may cause cracking or tool breakage. Leave a 0.2–0.3 mm allowance for rough machining, and finish with precision work to ensure smooth, round beads.
During machining, promptly remove chips. Wood can be cooled with air to prevent burning and tool adhesion. Keep the tool overhang as short as possible to enhance rigidity and reduce vibration. Clean the tool holder and collet 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.
