Improving Tool Life, Anti-Adhesion Performance and Machining Stability
As the cost of tungsten carbide and other tool materials continues to increase, while the supply of certain tool grades remains unstable, manufacturers are facing increasing pressure to reduce tooling costs while maintaining machining efficiency and quality.
During cutting operations, material adhesion, built-up edge (BUE), friction, chip evacuation and tool wear can significantly affect machining stability and tool service life.
POWER MICRO INTERNATIONAL has developed a Fullerene Self-Lubricating Anti-Stick Surface Modification Technology for cutting tools. By utilizing the characteristics of micronano Fullerene materials and introducing functional particles into the existing coating layer of the tool, the surface is modified to form a nano-scale structure with self-lubricating, anti-stick and wear-resistant properties.
The technology is designed to reduce friction and material adhesion during cutting, improve chip evacuation, suppress built-up edge formation, and optimize cutting tool service life.
During machining, cutting tools are continuously exposed to friction, cutting heat, material adhesion and mechanical loads.
When the workpiece material tends to adhere to the tool surface, the following problems may occur:
These problems can become more significant when machining difficult-to-cut materials or under demanding cutting conditions.
Instead of relying solely on higher-grade tool materials or changing machining parameters, surface modification can be used to improve the functional properties of the existing tool surface, particularly its friction, anti-adhesion and wear characteristics.
The technology utilizes Fullerene/Graphene functional particles to modify the surface of cutting tools.
Through a surface treatment process, functional particles are deposited onto the tool surface and introduced into the existing coating layer at the atomic level, forming a nano-scale structure and an interlocking structure.
Excellent Anti-Adhesion Performance
Material adhesion to the cutting edge can result in built-up edge (BUE), which may negatively affect cutting stability and surface quality.
The Fullerene Self-Lubricating Anti-Stick Surface Modification Technology helps reduce the tendency of workpiece materials to adhere to the tool surface, thereby suppressing material buildup and BUE formation.
Reduced Friction and Improved Chip Evacuation
By reducing friction between the cutting tool and workpiece material, the cutting process can become smoother and chip evacuation can be improved.
This helps reduce machining interference caused by poor chip evacuation and contributes to more stable cutting performance.
Reduced Wear and Extended Tool Service Life
The combination of anti-adhesion and friction-reduction characteristics helps reduce tool wear during machining.
By maintaining more stable surface performance, the technology can reduce tool replacement frequency and optimize overall tool service life.
Application Case: Self-Lubricating Anti-Stick Treatment for Cutting Tools
The technology can be applied to existing cutting tools to improve their surface performance through functional surface modification.
The modified tool surface provides the following potential benefits:
According to the company's current technical information, the process can achieve optimized tool life with significant service-life improvement. Actual performance depends on the tool material, existing coating, workpiece material and machining conditions.
The technology can be evaluated for various types of cutting tools according to tool material, existing coating and machining requirements.

The Fullerene Self-Lubricating Anti-Stick treatment can also be evaluated as part of a combined surface engineering solution.
Depending on the existing tool surface and machining requirements, it may be combined with other surface technologies, such as:
The appropriate combination can be selected according to the workpiece material, tool geometry, existing coating and actual tool failure mode.
