Indexable Inserts and Solid Ceramic End Mills

CERABOOST

Nickel-based superalloys are valued for their exceptional high-temperature strength, structural reliability and resistance to corrosion and fatigue, making them ideal for engineering components subject to high thermo-mechanical loads, particularly in the aerospace industry. However, their remarkable properties result in poor machinability, which limits processing efficiency. Challenges include high shear strength, tendency to work hardening, abrasive carbide precipitates and extreme temperatures at the tool-chip interface.

In addition, low thermal conductivity impedes heat removal, while the material’s high weldability causes built-up edge on cutting tools, further complicating machining operations and requiring advanced cutting technologies to improve performance and efficiency.

Palbit’s CERABOOST range combines advanced ceramic technology with optimised geometry to deliver outstanding performance and eff iciency in nickel-based alloys, from roughing to semifinishing.

The CERABOOST range of milling tools includes ceramic indexable inserts and solid ceramic end mills. They are designed to meet the different requirements of superalloys machining.

Ceramic Grades

To meet the challenges of machining advanced materials, ceramic cutting tools have been developed and are now regarded as one of the most effective solutions. Their excellent heat resistance and chemical stability, exceptional hardness, and wear resistance make them highly suitable for demanding applications.

Primarily composed of alumina (Al₂O₃) or silicon nitride (Si₃N₄), ceramic tools are tailored to meet specific requirements through the use of different grades and additives. These tools excel in high-speed machining and extreme environments, offering superior performance and high material removal rates compared to traditional materials, making them a preferred choice for demanding applications.

Key Benefits of the Ceramic Grades

■ Excellent heat resistance;

■ High hardness;

■ High wear resistance;

■ Excellent chemical stability;

■ Dry machining;

Palbit offers a special ceramic grade, PCN010, which can be either coated or uncoated, being ideal for machining nickel-based alloys, such as Inconel. The PCN010 grade, with a SiAlON composition, makes it possible to achieve high material removal rates under extreme operating conditions while minimising wear in roughing applications. SiAlON ceramic grades are characterised by their exceptional hardness and an extreme wear resistance allied with chemical stability.

The PCN010 grade, when coated, becomes the PCNY10 grade, offering several key benefits. These include easy wear detection, a low coefficient of friction, reduced material adhesion, and more stable wear progression.
