Separator™ Technical Recommendations • Separator Cut-Off System Improve chip control: Figure A • 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. Coolant on cut-off tool Preferred method of applying coolant 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. Figure B • 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). Minimise edge chipping: • Reduce feed rate. • Check to see if tool is significantly above or below centre. • Maintain sharp edge and corners on cut-off insert. • Reduce feed prior to part drop-off. • Increase speed (RPM). • Use Separator S2 or X2. • Use ample amounts of well-directed coolant (see Figure A). • Choose the proper speed associated with the insert grade used. • Maintain proper tool centre height 0–0,1mm above centre (see Figure B). • 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. Improve surface finish: – Thin wall collapses (deforms) in the cut. • For low to moderate speed (sfpm), use Separator F2. – Part is unstable. • For moderate to high speed (sfpm), use Separator S2 or X2. – Cut-off through unturned stock. • Avoid overly aggressive chip control. – Excessive tool overhang. • Increase speed. – Bent or partly attached flash ring. • Reduce lead angle and feed rate. • Determine if corner radius is too large or small. • Use a coated grade. • Use coolant (see Figure A).
