Kern Micro CNC Milling Machines | Rainford Precision

Ultra-Precision Without Compromise

Kern Microtechnik GmbH stands at the forefront of ultra-precision CNC milling, trusted globally by engineers who demand uncompromising accuracy. Renowned for engineering excellence, Kern machining centres deliver exceptional surface quality, repeatability, and long-term reliability, making them the benchmark for high-performance manufacturing environments.

For businesses looking to elevate capability, improve process stability, and reduce costly variability, investing in Kern technology is a decisive step forward. The result is not just tighter tolerances, but measurable gains in efficiency, consistency, and overall production economy.

As the exclusive UK and Ireland partner, Rainford Precision provides access to the full Kern Micro range, supported by expert guidance, application knowledge, and dedicated service. Our offering includes three advanced Kern Micro models, each engineered to meet the demands of modern precision manufacturing.

Kern Micro Vario

The second-generation Vario expands the boundaries of what compact high-precision machining can achieve. Designed for engineers who demand control, repeatability, and efficiency in equal measure, it introduces a refined balance of flexibility, productivity, and micron-level accuracy within an exceptionally small footprint.

At just 4 m², the Vario delivers a production-class machining environment without sacrificing valuable floor space. It inherits the proven accuracy, build quality, and competitive performance characteristics associated with the HD platform, along with an integrated 210-tool changer that keeps complex workflows fluid, uninterrupted, and highly automated.

While this configuration does not incorporate the micro-gap hydrostatic system found in the HD variant, its architecture remains engineered for exceptional stability. Thermal behaviour, structural rigidity, and dynamic consistency are all tuned to ensure dependable precision across demanding machining cycles. The result is a machine that holds its accuracy with quiet confidence, even under sustained production conditions.

Kern Micro HD

The KERN Micro HD sets a new standard in long-term precision engineering, combining uncompromising accuracy with outstanding cutting performance in a footprint of less than 5 m².

Designed for maximum capability in minimal space, it delivers exceptional surface quality and dynamic machining performance. The integrated tool system accommodates up to 210 tools, with optional automation for up to 60 workpieces, enabling highly efficient, uninterrupted production.

At its core, the Micro HD features micro-gap hydrostatic guideways, high-performance linear motors, and KERN’s advanced thermal management system—working together to ensure exceptional stability, repeatable precision, and long-term accuracy.

The result is a 5-axis machining centre that defines the benchmark for stability, dynamics, and micron-level manufacturing excellence.

Kern Micro Pro

The Pro, short for production, boasts a compact footprint of 4m2, making it suitable for all shop floors. With low maintenance costs and exceptional productivity, it is an ideal choice for businesses seeking efficiency and cost-effectiveness. The system can be easily managed and maintained during operation, without any interruptions while the machine is running. Additionally, it has a tool cabinet that can accommodate up to 210 tools and it offers various options for integrated workpiece changers, allowing for up to 60 workpieces to be utilised.

Kern Micro HD+

The Kern Micro HD+ advances ultra-precision machining through the integration of microgap hydrostatic technology within the B and C axes, significantly enhancing kinematic performance and long-term stability. The “+” designation reflects measurable improvements in axial and radial runout, dynamic behaviour, structural rigidity, and thermal stability—critical factors for next-generation high-precision applications.

The machine platform delivers exceptional process stability and repeatability across a wide range of machining strategies. Fully hydrostatic guideways and rotary axes eliminate metal-to-metal contact, removing wear mechanisms and ensuring consistent geometric accuracy over time. This design enables reliable, drift-free performance in continuous, fully automated serial production environments.

Optimised for the manufacture of complex, high-tolerance components, the Micro HD+ provides a robust foundation for micron-level accuracy, even under demanding thermal and dynamic conditions.

Moto Sport

We use OSG mainly but when we have a specific job that needs doing, we come to Rainford Precision because they are and do the Crème De La Crème of Products and services.

Works Manager

Precision Engineering

The End Mill was an ideal choice due to the unusual shape and the need to have a small radius. They turned out great, and the surface finish is really good.

External Works Manager

Precision Engineering

I would like to say thank you for the help you have given our project over the last few years. Your advice on the correct cutters plus the right speeds and feeds has not only helped with accuracy but brought the cycle times down so we can meet our project deadlines.
