Use a back clamp toolholder if there is no space for clamping tools from top side (automatic lathe). / - How to select cut-off inserts with / without lead angle (including sharp corner) 1. Use a neutral angle insert if there is no limit to the finished shape. 2. Use an angled insert to reduce the size of the remaining boss. 3. Use a sharp-cornered lead-angled insert to make the remaining boss much smaller when machining small parts and thin parts. N (Neutral) R (Right-hand) L (Left-hand) Angled (e) insert can reduce the burr size when cutting off. When using a larger lead angle (e), cutting force becomes smaller, but the feed rate should be reduced. Fig.1 Fig.2 Caution 1. For TKN and TK&, set the cutting edge height 0.1 0.2mm above the center height (Fig. 3) For other toolholders, set the cutting edge to the center height. 2. Be sure to perform wet processing. Apply enough coolant to the cutting edge. 3. Keep a constant rate during processing so that optimum product life will be achieved. 4. Cut off as close to the chuck as possible. 5. Lower the feed rate to 1/2 to 1/3 at the near center to prevent impact caused by machining. Overuse of insert and toolholder (blade) may cause insert breakage and toolholder (blade) damage. Do not rework the insert and toolholder (blade) to prevent damage. Clean the insert pocket well with compressed air when replacing insert. 0 e H3 Cut-off
