Productivity and wear resistance for stainless-steel turning

The CVD-coated cemented carbide grade T6215 delivers enhanced wear resistance in continuous and mildly interrupted turning of stainless steels, allowing longer tool life and fewer indexings. The coating improves thermal and abrasive resistance, which in turn maintains cutting-edge integrity under elevated temperatures common in machining rostfrei. This results in more consistent component dimensions and less downtime for insert changes, supporting a steady production flow.

Geometry and secure clamping for consistent surface quality

The CNMG120404 geometry with a rhombic form and 0.4 mm corner radius is optimised for a balance between strength and finish; the inserted corner radius helps control cutting forces and reduces burr formation on rolled or annealed stainless steels. A 4.76 mm plate thickness and the central cylindrical hole ensure secure clamping in compatible holders, while the nominal 80° approach angle supports versatile turning operations. These features contribute to repeatable results and predictable tool behaviour during setup changes.

Operational benefits and straightforward system integration

As an ISO-standard indexable plate, the insert integrates into conventional turning systems comprising the insert, a matching outer holder or boring bar, shim/clamp set and replacement screws. The double-sided chipbreaker enables two cutting edges per index, improving cost-efficiency by doubling service life before disposal. The 0° relief angle and standardised dimensions make selection and interchange simple, reducing setup time and increasing machine uptime for production runs.

FAQ

Which materials is this insert intended for?
The CNMG120404 T6215 insert from Tungaloy is optimised for machining stainless steels, offering a CVD-coated carbide substrate suited to stable and slightly interrupted turning conditions.

How does the chipbreaker influence cutting performance?
The double-sided chipbreaker on the CNMG120404 insert controls chip formation for improved evacuation and surface finish, reducing the risk of built-up edge when machining rostfrei materials.

Is the insert reversible and how many edges are available?
The indexable CNMG geometry provides reversible edges; with a double-sided chipbreaker the insert offers multiple cutting edges before replacement, improving cost-efficiency.

Which holders and clamping systems are compatible?
Compatibility is given by ISO CNMG standards; holders must match form, relief angle, tolerance class, clamping method, size and thickness for secure fastening of the CNMG120404 plate.

What are the key dimensional specs to check when replacing an insert?
Check the plate size (12), thickness (4.76 mm), corner radius (0.4 mm), relief angle (0°) and central hole style (cylindrical) to ensure correct fit and clamping.
