Contract Manufacturing and Assembly

Machine Park

As a manufacturer of complex three-dimensional micromechanical turned and milled parts, we have specialised in combining various machining techniques for optimal results: CNC turning, CNC milling, and wire erosion. A particular strength is the combined machining of small parts, where often the pre-milled or pre-turned material is reworked by wire erosion. This results in parts that could not be realised with a single technique.

We have optimised all our machines to efficiently execute even complex orders.

Our machine park allows us to produce micromechanical parts for industry as well as components of watch movements in small series. It must be borne in mind that a mechanical watch movement consists of up to 300 individual parts, all finely machined and fitting into just 2cm2 of space.

Thanks to experience in manufacturing haute horlogerie watch movements, we can offer, on request, extremely high-quality surface treatments, reworkings, as well as hardening/polishing of surfaces and parts.

In addition to traditional machines, our CNC machine park includes:

Turning:

7-axis décolletage up to diameter 20.00mm, gearing both in partial and generating methods, milling with fully automatic material feed.

We also mill internal threads from M0.35 in steel, brass, titanium, and beryllium bronze.

5-axis ultra-precision lathe with pick-up spindle, bar passage up to 42 mm, chuck turned parts up to 150 mm

CNC machining centres:

3-axis, spindle speed up to 35,000 rpm

automatic material feed

3-axis, spindle speed up to 40,000 rpm

automatic material feed

5-axis, spindle speed 35,000 rpm

automatic material feed

Wire erosion:

5-axis precision wire erosion machine with fine cut option, standard wire 0.1 mm

Laser:

100 x 100 mm, maximum workpiece height 150 mm, automatic material feed, engravings, surface structures, 3D machining of dials, minimum spot diameter approx. 0.02mm

3D printing:

4 3D printing systems, both for prototyping and contract manufacturing

All machining centres are equipped with a zero-point clamping system for palletisation of System 3R.

For special processes, we also develop machining machines from scratch (e.g. EWS gearing machine, weight 1700 kg)

Technical data

Wire erosion:

• With our wire erosion machine using a 0.1mm wire, we are also able to machine all conductive materials and thus every metal.

Analysis:

Optical-tactile coordinate measuring machine for quality control and precise measurement of produced parts.

Classical measuring methods, profile projector, all workstations equipped with stereo microscopes for inspection, manual carbide grinding machine with 6 axes, cup tool measuring system

Other machines:

• Manual lathe Schaublin 102 with cross slide and digital display
• Manual lathe Schaublin 120 with lead and guide spindle
• Various manual Schaublin and Aciera milling machines
• Drilling machine Hauser 2BA with digital display
• CNC milling machine with manual tool change for prototyping, spindle speed max. 10,000 rpm
• Ultrasonic cleaning system for fine cleaning of parts
• 4 assembly workstations with stereo microscope

Special tools

Our fixture construction specialises in the manufacture of assembly aids.

Especially the assembly of the smallest assemblies is simplified with good work preparation through the use of assembly aids. Depending on the order, we produce special gauges in which the components are correctly positioned and protected throughout the entire assembly process.

Qualified employees

Machines and tools are only as good as the people who operate them. UhrTeil AG is proud to have a team of dedicated employees who have been with us for a long time.

All our workshop employees are highly qualified and master 3D CAM programming, programming their machines independently.
