Achieve optical-grade surface quality with our single point diamond turning (SPDT) service. The copper components demonstrate the exceptional mirror finish and form accuracy that only ultra-precision single-point diamond turning can deliver.
What is Single Point Diamond Turning?
Single point diamond turning is an advanced ultra-precision machining process that uses a natural or synthetic single-crystal diamond tool to cut non-ferrous metals such as copper, aluminum, brass, and certain plastics. Unlike conventional CNC turning, SPDT operates at nanometer-level precision, producing surfaces with roughness values as low as Ra 1–5 nm and form accuracy in the sub-micron range.
This process is ideal for manufacturing high-performance optical and reflective components that require perfect surface integrity without the need for additional polishing.
Key Advantages of Our Single Point Diamond Turning Service
Optical mirror finish – Achieve true specular reflection directly from the machine
Exceptional form accuracy – Sub-micron contour control for aspheric and freeform surfaces
No post-polishing required – Significant time and cost savings
Superior material integrity – Minimal subsurface damage compared to grinding or polishing
High repeatability – Consistent results for prototype and small-to-medium production runs
Why Choose Us for Single Point Diamond Turning?
We combine advanced ultra-precision lathes with experienced process engineers to deliver reliable, high-quality results. Whether you need a one-off prototype or a small production batch, our team ensures tight process control, material traceability, and full dimensional inspection.
