Diamond turning at SURPRO
For over 50 years we have specialised in diamond turning on Swiss-type lathes. Using monocrystalline diamond tools, we create mirror-like, high-gloss surfaces directly in the cutting process – with no downstream polishing. The result: precision parts with excellent dimensional accuracy and brilliant looks.
Diamond bright turning
Bright turning with a diamond tool creates the mirror surface directly during turning. The result is an even high gloss without grinding or polishing steps – ideal for decorative and optical parts.
Diamond finishing of non-ferrous metals
Non-ferrous metals such as brass, aluminium, silver and gold are ideal for diamond turning. The fine-crystalline surface reflects light almost without loss and keeps its brilliance permanently.
Series on Swiss-type lathes
On modern Swiss-type lathes we produce high-gloss precision parts reliably in large and small series – with consistent quality and tight dimensional tolerances.
The benefits of
diamond turning
Diamond-turned surfaces reach a level of gloss that conventional processes cannot achieve.
Because the high gloss is created directly during turning, the elaborate post-polishing step is eliminated – saving time and protecting the part's dimensional accuracy.
Using monocrystalline diamond tools, we achieve extremely low surface roughness and a uniform, reproducible surface quality.
Mirror gloss without post-polishing
Minimal surface roughness
High dimensional accuracy and repeatability
For which
materials?
Soft to medium-hard non-ferrous metals are particularly well suited: brass, aluminium and copper as well as precious metals such as silver and gold.
Whether watch components, jewellery parts, optical components or technical precision parts – we find the right tool and process setup for your workpiece.
