Micron-Level Accuracy: Precision CNC Grinding & Machining Services
Unlike traditional metals, advanced ceramics require specialized diamond tooling and high-stiffness machinery to achieve precision. At Shunda Electronic Ceramics, we provide full-service CNC machining for Alumina and Zirconia, delivering tolerances as tight as ±0.002 mm. Whether it’s complex internal threads or mirror-polished surfaces, we ensure your ceramic parts fit perfectly into your assembly.
Our Technical Machining Capabilities
We master the art of ceramic finishing through a variety of high-precision processes:
5-Axis CNC Grinding: For complex 3D geometries and multi-angled features.
ID & OD Grinding: Precision internal and external cylindrical grinding for shafts and tubes.
Surface Lapping & Polishing: Achieving optical-grade flatness and surface roughness of Ra < 0.05 μm.
Micro-Hole Drilling: Capable of drilling precision holes as small as 0.1 mm in diameter.
Ultrasonic Machining: Ideal for fragile or ultra-complex structures to minimize micro-cracking.
Machining Tolerance Standards
Specialized Tooling & Quality Inspection
Ceramics are processed in their "hard" state using diamond-impregnated tools. To guarantee these specs, we utilize a climate-controlled inspection lab:
CMM (Coordinate Measuring Machine): Automated 3D dimensional verification.
Laser Interferometry: For ultra-precise flatness and parallelism measurement.
Surface Profilometry: Quantifying Ra, Rz, and surface topography.
Why Outsource Your Machining to Us?
Reduced Failure Rates: Our specialized cooling and feed-rate algorithms prevent thermal shock and edge chipping.
One-Stop Shop: We handle everything from raw material sintering to final micron-precision machining.
Complex Feature Expertise: We successfully machine internal threads and thin-walled structures that others find "impossible."
