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

Improve atness 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 nish:

• 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).

Preferred method of applying coolant

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.
