Improve chip control Adjust feed rate up or down to accommodate chip formation. Use a 0° or smallest lead available. Use ample amounts of well-directed coolant (see Figure A). Maintain sharp cutting edge and corners. Improve flatness of cut-off surfaces Maintain 90° position (perpendicular alignment) between cut-off tool and workpiece. For low to moderate speed (sfpm), use Separator F2. For moderate to high speed (sfpm), use Separator S2 or X2. Use strongest toolholder system possible. Use 0° lead angle inserts when possible. If lead angle inserts are needed, reduce the feed rate. Check for minimum overhang of holder and blade. Set up for minimum workpiece overhang (distance out of chuck). Reduce feed rate. Maintain sharp edge and corners on cut-off insert. Increase speed (RPM). Use ample amounts of well-directed coolant (see Figure A). Maintain proper tool centre height 0-0,1mm above centre (see Figure B). Improve surface finish For low to moderate speed (sfpm), use Separator F2. For moderate to high speed (sfpm), use Separator S2 or X2. Avoid overly aggressive chip control. Increase speed. Reduce lead angle and feed rate. Determine if corner radius is too large or small. Use a coated grade . Use coolant (see Figure A). Figure A Coolant on cut-off tool Preferred method of applying coolant Figure B Minimise edge chipping Check to see if tool is significantly above or below centre. Reduce feed prior to part drop-off. Use Separator S2 or X2. Choose the proper speed associated with the insert grade used. Call Technical Support to see if a larger hone size is needed. Eliminate chatter. Avoid chip re-cutting. Check for these part and machine problems - Slide is loose. - Slide travel is irregular. - Bar/tube I.D. and/or O.D. is out of round. - Bar/tube is bent. - Thin wall collapses (deforms) in the cut. - Part is unstable. - Cut-off through unturned stock. - Excessive tool overhang. - Bent or partly attached flash ring.
