Precision begins with machining the pressed powder

Why NADLER Hartmetalle relies on green machining

The difference in carbide manufacturing often starts earlier than you might think. Even before a part is sintered and ready for use, it is decided how precisely it will work later. At NADLER Hartmetalle, the focus is on exactly this early moment: green machining, when the carbide blank is still as soft as school chalk but already dimensionally stable – and can therefore be machined precisely.

Clamping the cylindrical part in a 3-jaw chuck shows how important this early machining step is in the overall process – inconspicuous in the workflow, but central to later dimensional accuracy.

Green machining with CNC technology: implementing contours precisely before sintering

In this sensitive manufacturing step, we make targeted use of the opportunity to carry out as many contour-forming machining steps as possible before sintering. Whether holes, grooves, threads or chip flutes: they are created exactly to drawing and require hardly any rework afterwards – because the part already largely has its final shape after sintering.

Advantages of green machining at NADLER Hartmetalle

• Complex geometries can be realized that hardly need to be machined after sintering.
• Cost-efficiency even for small quantities or one-off production
• Minimized effort in subsequent grinding
• High dimensional accuracy and repeatability for follow-up orders

Industry solutions with precision: mechanical engineering, medical technology & more

This approach pays off above all where tolerances are tight and requirements are high: in mechanical and special-purpose machine engineering, in food processing or in highly specialized applications. For custom solutions in particular, our green machining enables production at a completely different level of precision – matched to the later area of application.
