Macor Custom Parts Description

Macor Custom Parts provides a reliable solution for applications that demand both thermal resistance and design flexibility. Unlike conventional ceramics, Macor can be machined into detailed geometries—threads, holes, slots—without cracking or requiring post-firing. Its non-porous structure ensures zero outgassing, making it ideal for ultra-high vacuum and cleanroom environments. Engineers and designers often choose Macor custom parts for electrical feedthroughs, insulating fixtures, or mounting plates, especially when tight tolerances and rapid turnaround are critical. The ability to fabricate directly from raw blocks speeds up development and reduces tooling costs.

Macor Machinable Glass Ceramic Material Machining

Macor Machinable Glass Ceramic Material Machining

Macor is one of the rare ceramics that can be machined using standard metalworking tools without the need for post-sintering processes. This makes it especially useful for prototyping and custom part production with tight tolerances. However, understanding its machining behavior is key to achieving clean, precise results.

  • Standard Tool Compatibility: Macor can be drilled, milled, turned, and tapped using regular carbide or high-speed steel tools, eliminating the need for diamond tooling.
  • No Plastic Deformation: Unlike metals or plastics, Macor does not deform before breaking. Operators must prevent stress concentrations to avoid edge chipping or cracking.
  • Machining Precision: Surface finishes up to 0.5 µm and tolerances as tight as ±0.005 mm are achievable with careful planning and skilled handling.
  • Dry Machining Preferred: Coolants are generally not required. Dry machining helps prevent contamination and simplifies cleanup in high-purity applications.
  • Practice Recommended: Due to Macor’s unique cutting behavior, it’s recommended to practice machining techniques on scrap material before processing final components.

Macor Machinable Glass Ceramic Packaging

Macor machinable glass ceramic products are typically packaged in vacuum-sealed bags to prevent moisture or contamination and wrapped with foam to cushion vibrations and impacts during transport, ensuring the quality of products in their original condition.
