Infrastructure
for high-precision requirements
Advanced technologies are essential for top-tier precision work. Our machine park is modernised on an ongoing basis and, combined with the know-how of our dedicated team, paves the way for satisfied clients in Switzerland and abroad. Keller Precision relies on CNC 5-axis simultaneous milling and milling/turning centres, CNC 6-sided turning/milling centres and 3D coordinate measurement machines for demanding tasks. The measurement room, which is certified according to quality class 3 in accordance with VDI/VDE 2627, is at the heart of our top-quality precision work.
3D measurement room
for maximum process accuracy
Our measurement room is at the heart of our precision work. Kept at a constant temperature of 20±0.5 °C and a maximum humidity of 55 percent, we guarantee the most accurate measurement results to comply with minimal tolerances. Our measurement room meets all the requirements for quality class 3 according to VDI/VDE 2627, which also includes ISO 8 filters for particle retention and a guaranteed overpressure of 10 Pascal at all times. The airlock principle applies to the sectional doors, while a vibration-isolated, separate foundation ensures stable and reproducible measurement results. This allows us to meet the strictest quality standards and guarantee the highest measurement accuracy.
Specifications of the measurement room
- Measurement range up to X = 2,000, Y = 3,700, Z = 1,500 mm
- Quality class 3 measurement room according to VDI/VDE 2627
Turning centres and
turning/milling centres
We use our versatile turning centres and turning/milling centres to handle ultra-demanding manufacturing tasks. High-precision turning operations are combined with milling work to meet even the most complex geometries and tightest tolerances.
