From materials to finished products – precision machining and surface treatment of high-end alloy parts

Whether it’s turbine blades for aircraft engines or implantable components for artificial joints, they all place extremely high demands on material properties and surface quality. Bayi Automation Equipment has extensive experience in the processing and surface treatment of high-end metal materials, particularly in cobalt-chromium-molybdenum alloys, high-temperature alloys, and Kovar alloys.

II. Difficulties in Processing High-End Alloys
High Hardness: For example, cobalt-chromium-molybdenum alloys are highly hard, leading to rapid tool wear.

High-Temperature Resistance: High-temperature alloys are prone to work hardening during machining, making cutting difficult.

Special Coefficient of Thermal Expansion: Kovar alloys require precise dimensional control to achieve a perfect seal with ceramics or glass.

III. Bayi’s Solutions
Specialized Processing Equipment and Tools: We select the appropriate tool material and cutting parameters based on the characteristics of each material.

Plasma Polishing and Ultrasonic Cleaning: We remove surface micro-defects, improving finish and corrosion resistance without changing workpiece dimensions.

Customized Processes: We design specialized fixtures and machining paths for special-shaped parts to ensure efficient and stable machining.

IV. Typical Application Cases
Medical Implants: After plasma polishing, the surface finish of artificial joints and dental restorations can reach Ra0.02, significantly improving biocompatibility.

Aerospace Parts: Precision machining and surface treatment of high-temperature alloy sealing rings increase their lifespan by over 30%.

Electronic Packages: Surface treatment of Kovar alloy pins significantly enhances their airtightness with glass packaging.

V. Future Trends
Future high-end alloy processing will rely more heavily on automation and data-driven processes. Bayi is developing intelligent equipment with online detection and feedback capabilities, enabling full traceability of processing data for every part.
