First, verify your lathe toolholder center height is precisely within ±0.05mm. If the tool path hits heavy cross-holes or raw scale, reduce your cutting speed (Vc) or pivot to the tougher AC820P grade.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"background-color: #f7f7f9; border-left: 4px solid #47479F; padding: 12px 15px; margin-bottom: 0; border-radius: 0 4px 4px 0;\"\u003e\n\u003cdiv style=\"font-weight: bold; color: #111111; font-size: 15px; margin-bottom: 5px;\"\u003eQ3: Why am I getting stringy nest chips at a shallow 0.20mm depth of cut?\u003c\/div\u003e\n\u003cdiv style=\"color: #444444; font-size: 14px;\"\u003eA3: The -SU chipbreaker requires a minimum volume of material to effectively engage its deflector walls.
