The medical industry uses precision cutting tools for milling, micro milling, drilling, micro drilling, reaming, profiling and finishing components intended for medical devices, surgical instruments, orthopaedics and dental applications.

Tool selection mainly depends on the workpiece material, component dimensions and geometry, required tolerances and desired surface quality.

Nuova Cumet offers carbide milling cutters, micro end mills, drills, micro drills, reamers and custom cutting tools for materials used in the medical industry, such as titanium, stainless steels, zirconia and other engineering materials.

Titanium is widely used in medical applications and requires cutting tools capable of maintaining precision and cutting edge stability while controlling heat and wear.

Carbide cutting tools with geometries and coatings specific to titanium alloys can be used for milling, drilling and producing complex details.

Nuova Cumet offers cutting tools dedicated to machining titanium and, through MyCarbide, can develop customised geometries and coatings according to the component and production process.

Manufacturing components for dental implantology and dental applications requires cutting tools capable of machining very small, complex geometries while maintaining tight dimensional tolerances and high repeatability.

Micro end mills, ball nose end mills, corner-radius end mills, form cutters, drills and micro drills can be used, with geometry and dimensions selected according to the material and component.

Nuova Cumet manufactures custom cutting tools also for dental and implantology applications, including milling cutters starting at very small diameters and customised micro drills.

Stainless steels used in the medical industry require cutting tools designed to maintain cutting edge stability and limit the effects of heat, friction and wear.

Tool geometry, carbide, coating and cutting parameters must be selected according to the specific steel type and machining operation.

Nuova Cumet offers milling cutters and other cutting tools for stainless steels; for the most critical applications, MyCarbide can also use PVD coatings specifically designed for stainless steel.

Orthopaedic components and surgical instruments may require milling, profiling, drilling, micro drilling and finishing of materials such as titanium and stainless steels.

Machining must ensure high geometrical accuracy and repeatability, especially with complex shapes and tight tolerances.

Nuova Cumet and MyCarbide develop standard and custom cutting tools for medical and orthopaedic applications, adapting geometry, dimensions and coating to the machining requirements.

Small geometries require cutting tools with high geometrical accuracy, small diameters and a sufficiently rigid machine–tool system.

Micro end mills, ball nose or corner-radius end mills and form tools enable the production of cavities, profiles, radii, grooves and very small details.

Nuova Cumet manufactures flat, corner-radius and ball nose end mills starting at Ø 0.2 mm and can customise diameters, geometries and working lengths according to the application.

Hole accuracy depends on drill geometry, system rigidity, cutting parameters, coolant delivery and material characteristics.

When particularly tight tolerances are required, drilling can be followed by a reaming operation.

For complex components, custom drills or micro drills designed to produce multiple diameters or geometries in a single operation can also be used.

Yes. In certain medical applications, step drills or micro step drills designed to produce multiple diameters in a single operation can be used.

This solution can reduce the number of tools required and tool changes, while also improving geometrical repeatability between the different sections of the hole.

Nuova Cumet manufactures cylindrical and step drills and micro drills designed also for “one-shot” machining.

Tool life depends on the combination of carbide quality, geometry, coating, coolant delivery, cutting parameters and machining system rigidity.

With materials such as titanium and stainless steel, it is particularly important to control heat, friction and cutting edge wear.

A material-specific geometry and suitable coating can help improve process stability and extend tool life.

A custom cutting tool is particularly suitable when a standard tool cannot deliver the required precision, surface quality, geometry or productivity.

In the medical industry, it can be useful for very small components, complex shapes, multi-diameter holes, specific profiles or machining operations requiring tools with particular working lengths.

Nuova Cumet can customise tool geometry, dimensions, carbide grade and coating according to the application.

Materials such as zirconia have very different characteristics from metal alloys and can cause significant tool wear.

Selection must therefore consider cutting edge geometry, tool material, abrasiveness and machining conditions.

For highly abrasive non-ferrous materials, Nuova Cumet also offers solutions with CVD diamond coatings, whose type and finish can be adapted to the application requirements.

The coating should be selected according to the workpiece material and cutting conditions.

Specific PVD coatings can be used for machining titanium and stainless steel, while CVD diamond coatings can be adopted for highly abrasive non-ferrous materials.

When designing a custom cutting tool, geometry, carbide grade, coating type, thickness and finish can be assessed together.

Precision and repeatability depend on the entire machining system: tool, machine, toolholder, cutting parameters, material and wear control.

A cutting tool designed specifically for the machining operation can help maintain more consistent dimensions and geometrical characteristics during repetitive production.

In the medical industry, where very small geometries and tight tolerances may be required, tool accuracy therefore plays a particularly important role.

Yes. Through MyCarbide, Nuova Cumet develops custom cutting tools based on the characteristics of the component, material and production process.

Diameters, lengths, profiles, number and geometry of cutting edges, carbide grade and coating can be customised.

Available solutions include flat, corner-radius and ball nose end mills, form cutters, cylindrical or step drills and micro drills, and other custom cutting tools.

To design a custom cutting tool, it is helpful to understand the component and production process in detail.

The following are particularly important:

• component drawing;
• workpiece material;
• operation to be performed;
• geometry and dimensions;
• diameters and depths;
• required tolerances;
• desired surface quality;
• machine and spindle used;
• coolant system;
• cutting parameters;
• production quantity;
• tool already in use, if any;
• current tool life;
• any wear, breakage or quality issues.

This information enables the development of a cutting tool truly suited to the machining conditions and production targets.
