Our specialty is the manufacturing of miniature components and assemblies with complex geometry, tight tolerances and a high demand for surface finish.

Mirror for laser optics, the conical mirror surface has been diamond burnished	Wire guides, material is tungsten carbide. The inner diameter and lead in radius have been ground and polished	Test fixture for a optical inspection machine

Special Attention is taken when it comes to edge treatment, demurring, surface finish and cleanliness.
Inspection of dimensions is done via a wide range of tactile measuring instruments, we also have access to an high precision measuring microscope.
If needed, we will design and build custom gages or test fixtures for your project.

We reverse engineered and manufactured these lamp holders for a Kern Theodolite	The part was designed in CAD with the aid of a damaged original part

Capabilities

Turning: Starting at diameter 1mm
Drilling: Micro drilling starting at 0.3mm
Milling: Smallest endmill diameter 0.3mm / Thinnest saw blade 0.2mm

We have access to a number of grinders for making or modifying tools and tooling for special operations.

Covers, machined from PEEK	Vent screws - Machined from titanium, Torx Tx8 drive, thread M4x0.35	Housings for Collimator optics, machined from stainless 1.4305

Furthermore we have wide experience in prototyping parts that will later become stamped and formed sheet metal parts in production..

A specialty of ours is the refurbishment of drill press spindles with an fixed male taper (B-XX taper). These are mostly used in smaller/medium sized bench top drill presses like the Flott TB series.

These tapers can be easily damaged by crashing tools like a holes saw, large forstner drills or hole cutters - This can lead to either a bent spindle/taper nose or a drill chuck that spins and galls the taper nose.

Vorgehensweise:

• A severely bent spindle is pre-straightened on a hydraulic press
• After inspection and cleaning of all components, the entire spindle is assembled with new bearings
• The spindle taper will be ground with the spindle running in its own bearings, this ensures optimal runout, usually as good or better as from factory.
  If the spindle did not require mechanical straightening, it is often enough to just have the spindle taper ground to get an excellent results.

If desired, we can also source new drill chucks (Usually Röhm or Albrecht), Bearings (We generally use NSK, SKF or FAG bearings) and other spare parts if needed.

A refurbishment of spindles with internal taper is not possible at this point in time.
