Surgical instrument machining: Precision for the highest standards

The highest demands regarding material, processing and surface quality for long-lasting and reliable instruments.

Surgical instruments must meet the highest functional and hygienic requirements. The materials used are internationally standardised and are mostly made of hardenable chromium steels with low to medium carbon content.  The chromium content is >12.5%, as only with this content can sufficient corrosion resistance be guaranteed. 

The most important production step is tempering, which ensures the necessary levels of hardness, toughness and resistance. In addition, perfect burr-free production is essential to ensure safe use in the medical sector.

Precise machining for long-lasting surgical instruments

State-of-the-art production technologies enable maximum dimensional stability and excellent surface quality for safe use in surgery.

Materials and production

The manufacture of surgical instruments requires highly specialised materials and manufacturing technologies.

  • Hardened chrome steels e.g. 1.4021, ISO-P High strength and corrosion resistance
  • Chrome-nickel steels e.g. X8CrNiS 18-9, ISO-M: Not hardenable, but suitable for special instruments
  • Tempering: Increased hardness, toughness and corrosion resistance
  • Perfectly burr-free: Ensures high patient safety

Machining technologies

The instruments are machined using high-precision manufacturing technologies for precise geometries and optimum surface quality.

  • Milling: High-precision production for perfect contours
  • Drilling: Precise hole processing for surgical tools
  • Chamfering and deburring: Precise machining for perfect geometries. We prioritise burr-free finish on workpiece edges.

Characteristics of surgical instruments

  • High-quality materials
    Manufactured from hardenable chrome steels or corrosion-resistant chrome nickel steels for maximum durability.
     
  • Optimised surface quality
    Smooth and polished surfaces to minimise germ adhesion and for easy sterilisation.
     
  • Precision production
    Optimum dimensional accuracy thanks to modern milling techniques for perfect functionality.

"Surgical instruments" machining
