Use a more rigid toolholder (blade). oolholder 3. Use a back clamp toolholder if there is no space for clamping tools from top side (automatic lathe). ow to select cutoff inserts with / without lead angle (including sharp edge) 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 sharpcornered leadangled insert to make the remaining boss much smaller when machining small parts and thin parts. and of ead Angle (eutral) (ighthand) (efthand) Angled (q) insert can reduce the burr size when cutting off. hen using a larger lead angle (q), cutting force becomes smaller, but the feed rate should be reduced. Example: Solid orkpiece Example: ollow orkpiece (Pipe) ighthand ead angle Fig. 1 eutral Sharp Corner Fig. 2 Bigger boss ead angle Cutoff Caution 1. For K and K&, 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.. Cutoff as close to the chuck as possible. 5. ower 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. Cutting Edge eight orkpiece Fig. 3 (K, K&) 3
