WhizCut Back Turning Inserts for CNC Swiss Automatic Lathes

Advantages with WhizCut back turning inserts

Low radial forces
Gives better roundness on the component
Keeps the desired size longer without adjustment
Chip is curled before it hits the already finished shoulder
Gives good chip-control by curling the chip away from the surface

Positive cutting rake improves production and tool-life
Only a narrow parting off insert is required in order to clean up the non finished cylindrical diameter
The final diameter is produced only 1 mm from the side of the insert and tool holder, or away from the guide bushing, resulting in good stability even when small diameters are produced
Small distance from the side to end of wiper which makes final diameter. Very suitable for small diameters.

Back Turning Insert Guide

Style C

Style C is used when there is an undercut required.

Style BT

Style BT inserts has a chamfer on the leading corner that improves the tool-life in harder materials. This insert is suitable when the wear on the style B insert is found in an early stage.

Style B

Style B is for general use in back turning applications in stainless steel, titanium, nimonic, hastaloy, high temperature alloys, alloyed steel and other hard and long chipped materials where good chip control is needed.

Style VLR

Style VLR is used for backturning when a smooth surface is needed when profiling. It is for example excellent to go in behind the head of a bone screw with.

Style BP

Style BP is used for sticky materials when there is a chance of an edge build up that can spoil the surface finish or reduce tool-life.

Style E

Style E is used for fine turning, using high cutting speed and low feed rate. This insert will give the best possible surface finish. By protecting the radius with the chamfer the tool life is extended compared with conventional full radius inserts.
