Technical Ceramic CNC Machining
Controlled machining of alumina, zirconia, silicon carbide, and technical ceramics for demanding environments beyond typical metal performance.
Why Ceramics Require Specialized Machining
Extreme hardness means conventional carbide tools fail rapidly — diamond tooling is essential. Brittleness requires careful control of cutting forces to prevent crack propagation. Low thermal conductivity can cause localized overheating, demanding precision coolant delivery. Technical ceramics present unique machining challenges that metals and plastics don't.
Nelotiv facility combines specialized diamond tooling, expert operators trained in brittle material processing, and precision CNC equipment to deliver ceramic components that perform in the most demanding applications — from aerospace thermal barriers to medical implants.

Why Choose Nelotiv for Ceramics
Specialized PCD & CVD Tools
Standard carbide tools fail rapidly on ceramics. We maintain a full inventory of diamond cutting tools — polycrystalline diamond (PCD) and chemical vapor deposition diamond (CVD) — each selected for specific ceramic types and machining operations. Tool wear monitoring help maintains consistent precision throughout production runs.
Certified Quality & Traceability
Every ceramic part ships with full documentation — material test reports, certificates of conformance, inspection records. Medical device customers receive ISO 13485 compliant processing with FDA-grade materials. Nelotiv quality system help maintains consistency from prototype to production volumes.
Design for Ceramic Manufacturing
Ceramics behave differently than metals — they're brittle, sensitive to stress concentration, and require generous radii. Nelotiv engineering team delivers DFM review specifically for ceramic parts, identifying geometry risks and suggesting modifications before machining begins. This prevents costly failures and help maintains first-part success.
