CNC Machining Of Cast Iron

At KOCKUMS Maskin AB, CNC machining is more than a production step. It is a critical part of ensuring that your cast iron components meet exact functional, dimensional and quality requirements – every time.

We support OEMs and industrial manufacturers with cast iron CNC machining that combines advanced CNC technology, deep material expertise and a production setup designed for efficiency, repeatability and long-term reliability.

Whether you require prototypes, small batches or high-volume series, we act as a stable machining partner who understands both engineering demands and commercial realities.

Precision machining tailored to cast iron applications

Cast iron machining requires a detailed understanding of material behaviour, tool wear and process stability. Our machining operations are organised in item-specific production groups, allowing us to optimise processes for different component geometries, tolerances and series sizes.

We primarily machine grey and ductile iron in all common grades, handling components up to 100 kg with consistent accuracy. Our experience ensures reliable results across complex geometries and demanding tolerances.

For customers working with nodular iron, our expertise in ductile iron machining ensures controlled machining processes that preserve material integrity while delivering the required mechanical performance.

From raw casting to finished, ready-to-assemble components

KOCKUMS Maskin delivers machined castings that integrate seamlessly into your downstream production. By combining CNC machining centres with conventional lathes, milling, drilling and grinding machines, we select the optimal process for each feature and tolerance requirement.

Our machining services are designed to support both functional surfaces and high-precision interfaces, ensuring consistent quality across all delivered parts.

The result is precision machining cast iron parts that reduce assembly risk, minimise rework and support predictable performance in your end product.

Flexible capacity for serial production

Industrial customers often face fluctuating demand, tight lead times and pressure to maintain cost control. Our production setup is designed to support serial production machining cast iron with a high degree of flexibility.

We manage:

Small, medium and large series
Stable repeatability across production runs
Reliable delivery performance aligned with your supply chain

This allows you to scale production without compromising quality or delivery reliability.
