When machining aluminium, the insert geometry matters just as much as the carbide grade. Aluminium can produce built-up edge and burrs when the cutting edge is not suited to the material. Cargo Carbide CCGT Aluminium Inserts are designed around a positive turning geometry for CNC machining of aluminium and other non-ferrous materials.

CCGT is an 80° diamond-shaped, positive 7° relief insert commonly used for aluminium cutting. Manufacturer and tooling references position CCGT-AL inserts for aluminium/non-ferrous machining, including profile and general shaft-turning applications.

The G-tolerance / precision-ground format makes CCGT particularly relevant where repeatable insert positioning and accurate component geometry are important. CCGT aluminium inserts are available in different IC sizes and corner radii, allowing the insert to be selected according to the component size, profile, depth of cut and required surface finish.

For finishing-oriented aluminium machining, a sharp and polished cutting edge is especially useful. Current CCGT aluminium products in the market emphasize polished rake faces and sharp cutting edges for reducing cutting forces and helping control built-up edge during aluminium machining.

Cargo Carbide CCGT Aluminium Inserts are therefore best positioned for customers searching for a dedicated CNC turning insert for aluminium rather than a general steel-turning insert.

Why CCGT for Aluminium?

CCGT → Positive 7° → 80° Diamond → Aluminium → CNC Turning → Finishing/Profile Turning

Recommended Applications

Aluminium CNC Turning

Suitable for machining aluminium components on CNC lathes.

Profile Turning

The CCGT geometry is commonly used for profile and contour-related turning applications.

Shaft Turning

Suitable for appropriate aluminium shaft and cylindrical-component machining.

Finishing

A sharp, polished CCGT configuration is particularly relevant to aluminium finishing where surface quality and controlled cutting are important.

Other Non-Ferrous Materials

Depending on grade and cutting conditions, CCGT products are also used for non-ferrous materials beyond aluminium.

CCGT vs General Carbide Inserts

A customer machining aluminium should not automatically select the same insert used for steel.

CCGT aluminium geometry is designed around the requirements of non-ferrous machining, with positive cutting action and a geometry commonly used for aluminium turning and finishing.

FAQ 

What is a CCGT aluminium insert?

A CCGT aluminium insert is a positive CNC turning insert commonly used for machining aluminium and other non-ferrous materials. CCGT generally uses an 80° diamond shape with positive relief geometry.

What is CCGT used for?

CCGT inserts are commonly used for aluminium turning, profile turning, shaft turning and finishing applications.

Is CCGT suitable for aluminium?

Yes. CCGT is specifically positioned by tooling manufacturers for aluminium and non-ferrous machining.

What is the advantage of a positive CCGT insert?

The positive geometry is suited to aluminium machining where controlled cutting action and a sharp cutting edge are important. Polished CCGT versions are marketed specifically for aluminium finishing and reducing built-up edge.

What is the difference between CCGT and CCGT-AL?

CCGT identifies the insert geometry/designation. CCGT-AL is commonly used commercially to identify a CCGT configuration intended for aluminium cutting. Tungaloy, for example, identifies its CCGT-AL family as a positive 7° G-class insert for aluminium cutting.

Can CCGT be used for non-ferrous metals?

Yes. CCGT products are listed for aluminium/non-ferrous materials, although the appropriate grade and cutting parameters should be selected for the particular material.
