Separator ™
Technical Recommendations • Separator Cut-Off System
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.
Figure A
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 F 2.
• For moderate to high speed( sfpm), use Separator S 2 or X 2.
• 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 F 2.
• For moderate to high speed( sfpm), use Separator S 2 or X 2.
• 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 B
Minimise edge chipping:
• Check to see if tool is significantly above or below centre.
• Reduce feed prior to part drop-off.
• Use Separator S 2 or X 2.
• 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. widia. com
