Corocut XS inserts from Sandvik Coromant feature a front angle increased

Corocut XS inserts from Sandvik Coromant feature a front angle increased to 20deg to improve component quality in parting operations.

The main application is in sliding head machines without a sub-spindle.

Here, customers can achieve higher productivity and better component finish as the insert edge design offers pip and burr-free surfaces.

The inserts are precision ground and available in grade GC1025 for material groups ISO P, ISO M and ISO K.

When parting with a sub-spindle it is more productive to use a straight cutting edge as this is a more stable parting method and will generate the best surface finish.

However, when parting without a sub-spindle it is recommended to use an insert with a minimum insert angle of 15deg to minimise the risk of burr and pips on the component.

Corocut XS parting geometry is designed specifically for precision-made components.

The geometry makes the chip narrower than the groove, which provides chip control.

Parting-off inserts are available in widths down to 0.7mm.

Sandvik Coromant's Corocut XS is a tangentially mounted system for precision machining using sliding head machines.

As well as parting-off, the system is available for a number of other external turning operations, including grooving.

Grooving inserts are available in 0.5, 1.0, 1.5, 2.0 and 2.5mm widths.

In terms of toolholders to accompany Corocut XS, parting and grooving sets high demands on accessibility since the inserts are often fed deep into the material.

This means narrow machining and therefore the length of the tool increases in line with the diameter.

Tools and tooling systems with high stability are therefore very important.

For best economy, Sandvik Coromant recommends its QS holding system as a productive alternative to conventional toolholders when used on sliding head machines.

In comparison with the 12 steps required when changing conventional one-piece toolholders, the QS system offers an efficient two-step set-up procedure to reduce downtime.

The single screw release design of the QS tool holder will reduce toolchange times by around 66 per cent, while the spring-loaded wedges ensure quick and safe extraction and reduce the risk of dropping the holder.
