CNGA 120402 BX360 Wendeplatten - Tungaloy

Take advantage of the CBN cutting grade BX360 and the ISO CNGA120402 rhombic geometry for consistent finish turning of hardened components; the combination of high wear resistance and standardised form reduces tool-change uncertainty and keeps production flowing — order the CNGA120402 BX360 insert directly via Metav Werkzeuge or ask the consultants for application support.

CNGA 120402 BX360 Tungaloy turning insert — CBN grade for turning

A CNGA120402 BX360 turning insert engineered for finish turning of hardened steels and, depending on grade variant, select cast irons, offering ISO interchangeability with rhombic geometry and a cylindrical centre hole for secure clamping.

• CBN grade BX360 for hardened steels
• ISO CNGA120402 rhombic geometry
• 0.2 mm corner radius for fine finishes
• Cylindrical hole for secure clamping

Reliable performance in hard turning with CBN

The BX360 grade uses cubic boron nitride (CBN) as the cutting material, which delivers superior wear resistance on hardened steels compared with conventional carbide grades. For finish and light roughing operations on workpieces hardened to high strength levels, this CBN formulation extends productive cutting life and reduces the frequency of tool indexing. The result is a more predictable machining cycle and improved uptime for serial production runs.

Precision geometry that supports repeatable surface quality

The ISO CNGA120402 form provides a defined rhombic geometry and a stable bearing face for the insert seat; combined with a 0° relief angle and an 80° main cutting edge angle, the geometry helps maintain consistent contact and cutting conditions. The small 0.2 mm corner radius is optimised for fine finishes and tight dimensional control, while the 4.76 mm plate thickness contributes to rigidity in the holder. These geometric parameters translate into better surface finish and repeatable part tolerances on turned components.

System compatibility and process stability

Designed as part of an ISO-standard insert system, the package works with matched external holders or boring bars, plus a backing shim and clamping set where needed. The cylindrical centre hole provides a positive reference for secure fastening and accurate seating. Note that this variant is supplied without a chipbreaker, so selection of machining parameters and coolant strategy should reflect a finishing application or stable chip evacuation conditions. Using standardised inserts reduces setup variability and allows for fast replacement during production.

Practical application notes and handling

Intended primarily for turning, both external and internal operations can benefit from the grade when machining hardened materials. The BX360 CBN cutting edge is particularly effective in end-finishing passes where wear resistance and edge stability are critical. When specifying a holder, confirm compatibility by matching the CNGA form, the insert thickness and the hole arrangement to ensure correct clamping. Store inserts in their original packaging and handle by the sides to protect the cutting edge and preserve tool life.

FAQ

Is this insert suitable for hardened steels?
The CNGA120402 BX360 insert is specifically designed for hardened steels; the BX360 CBN cutting material provides high wear resistance for finish machining of hardened components.

Can this insert be used in standard CNGA holders?
Yes, the insert follows ISO CNGA120402 dimensions and fits holders that accept the CNGA form with the corresponding thickness and hole arrangement.

Does this variant include a chipbreaker?
This version is supplied without a chipbreaker; it is optimised for finish turning where chip control is managed by cutting parameters and tooling setup.

What does the 0.2 mm corner radius mean for surface finish?
A 0.2 mm corner radius produces a fine surface finish while still providing some edge strength for finishing passes; it helps control tool pressure and part geometry.

Is the BX360 grade suitable for cast iron as well?
Depending on the specific BX360 variant, performance on cast iron can be achievable; confirm the intended workpiece material and machining mode before selection.
