High accuracy and reproducible quality
Okamoto CNC CHiQ machines are designed for industrial precision grinding operations where dimensional accuracy and low surface roughness are crucial. The rigid machine construction and high-quality guides minimise vibration, resulting in:
- very high dimensional accuracy
- low surface roughness
- stable and consistent grinding results
This makes our grinding operations ideal for applications where precision surface grinding is essential.
Efficient surface and profile grinding
Our machines are equipped with intuitive and user-friendly controls similar to those of our other Okamoto surface and profile grinding machines. This ensures a high degree of process reliability and uniformity within our industrial grinding centre. Multiple machines can be deployed flexibly, enabling us to scale up efficiently and guarantee reliable delivery times.
Large capacity for long and heavy workpieces
With grinding lengths of 2 meters, 2.5 meters and 3.5 meters, our Okamoto CHiQ machinery has an exceptionally large capacity. This means we are ideally equipped for:
- surface grinding of large workpieces
- surface grinding of long workpieces up to 3.5 meters
- small and large series
- precise grinding of complex components
Specialist in industrial surface grinding
Whether it concerns dimensionally stable grinding, precision grinding or machining long components we combine high-quality Okamoto surface grinding machines with craftsmanship and process control. This enables us to deliver consistent quality that meets the highest industrial requirements.

Heavy Frames, High Accuracy
Many of the frames we process weigh tens of thousands of kilograms and require machining across all sides. A typical example is a construction measuring 5,000 × 2,700 × 2,000 mm and weighing 23,000 kg, a size and weight that only a small number of machining suppliers in Europe can accommodate.
Welded or cast, these structures often come with their own challenges:
- Heat distortion
- Internal stress
- Geometric deviations
- Large, uneven surfaces
Correcting these issues with precision demands not only powerful machinery but also extensive expertise in handling complex heavy structures. De Rooy offers:
🔹 Large-capacity CNC machining for multi-ton frames in oversized dimensions
🔹 Specialists in welded and thick-walled constructions
🔹 Advanced fixturing and in-process measuring for accuracy over large distances
🔹 Stable, repeatable processes suited for both single pieces and recurring production
Supporting Europe’s Traditional Industries
Our machining services support OEMs in:
- Heavy agricultural machinery
- Mining and earth-moving equipment
- Offshore and marine systems
- Shipbuilding infrastructure
- Metal production and processing equipment
- Chemical and process industry machinery
In these sectors, durability is essential, but precision is too. Even small dimensional deviations in a 20-ton frame can lead to assembly issues, increased wear, or reduced system efficiency.
Our ability to machine extremely heavy frames to tight tolerances ensures these components integrate seamlessly into your final equipment.
Why a European Machining Partner Matters
For traditional industries, choosing a European supplier like De Rooy provides major advantages:
🔹 Lower Logistics and Shipping Costs
Transporting a 23,000-kg frame across continents is costly and complex. European production significantly reduces shipping time and expense.
🔹 Faster and More Flexible Delivery
Shorter supply chains mean quicker adjustments, faster lead times, and smooth handling of design changes.
🔹 Direct Communication and On-Site Collaboration
Engineers can visit, inspect, and collaborate easily improving quality and reducing project risk.
🔹 Reduced Risk in Complex Projects
Local machining eliminates long transit risks, customs delays, and logistical uncertainty.
Built for Heavy-Duty Machining Needs
Our facilities, equipment, and team are specifically equipped to handle oversized industrial frames that few suppliers worldwide can machine. Whether it’s a 23-ton welded frame for mining equipment or a large base structure for chemical processing machinery, we deliver precision, consistency, and reliability. De Rooy is ready to support traditional industries with dependable machining of large, heavy, and complex structures delivered with the accuracy your machinery demands.
