High precision CNC turning
We turn metals such as aluminum, steel, high-grade steel or brass alloys as a CNC contract manufacturer. Our production depth reaches from small-batch, to medium-batch up to large-scale quantities processing parts of various geometry or complexity.
With the experience of more than 70 years in fine mechanics/ optics, we are specialists in the CNC turning of thin-walled and complex turned parts. Especially the turning of internal and external threads with slim tolerances as used for optical filters or lens systems are produced in small and medium batch series.
ISO tolerances of IT6 are the base for producing high quality in the optical industry. Monitored by our own accredited measuring and calibration laboratory those tolerances are continuously controlled by complex CAQ software.
Complete 6-axis turning & milling machining
Aside from conventional CNC turning, PENTACON is processing products on 6-axis turning and milling machining with complex contours. Here we produce guide slots, move slots or control curves on on lateral an flat faces. Those types of millings are usually used in sliding mounts, zoom lenses or photographic apertures and require utmost precision.
Surface finishing (in cooperation)
In cooperation with partners, we are finishing CNC turned parts. Below is a list of mechanic, galvanic or chemical surface treatment we are offering:
- alu-chromate Cr-6 free
- zinc processing
