Grinding technical ceramics

Technical ceramics withstand extreme temperatures, wear and corrosion, and are increasingly replacing metal and plastic – yet only a few suppliers have mastered their machining.

Materials such as zirconium dioxide (ZrO₂), aluminium oxide (Al₂O₃) or Macor offer properties that traditional materials cannot achieve: high hardness, electrical insulation, chemical resistance and dimensional stability even under high heat. This hardness makes grinding the only practical machining method.

Why ceramic grinding is challenging

Ceramics are hard and at the same time brittle. During grinding, the infeed and cooling must be selected so that no edge chipping and no micro-cracks occur. This requires diamond-tipped grinding tools, sensitive process control and a great deal of experience.

• Diamond grinding for high dimensional and geometrical accuracy
• Gentle process management to prevent edge chipping and micro-cracks
• Finest surfaces for sealing and tribological functional surfaces
• Ideal for applications involving extreme wear, heat or insulation requirements

A unique selling proposition

Because only a few finishers offer the grinding of technical ceramics, it is a true differentiator – and the right answer when metal or plastic reach their limits.
