- A roll-grinding machine is specialized equipment for precision grinding and finishing of metal surfaces with rotating abrasive wheels. It is used in metalworking and heavy engineering to restore accurate, smooth surfaces on rolls and other large components.
- Key Capabilities:
- Extends roll service life by restoring geometry and surface quality.
- High-precision grinding after hot or cold rolling.
- Processes cylindrical, tapered and flat surfaces.
- Handles components weighing more than 150 tonnes.
Advantages of Our Machines:
Machining of components in any size and configuration.
Surface finish down to Ra 0.1 μm.
Extended equipment service life.
Surface finish down to Ra 0.1 μm.
Extended equipment service life.
- Customization for customer-specific requirements.
Roll-Grinding Machines
Exima PRO supplies high-precision roll-grinding machines, including two-axis models for work and backup rolls. Our equipment can process rolls weighing up to 200 tonnes for heavy plate mills such as Mill 5000.
Applications:
Metallurgical plants: restoration of rolling-mill rolls.
Mechanical engineering: shafts and critical components.
Pulp and paper production.
Heavy-equipment component manufacturing.
Operating Principle:
1. The workpiece is securely fixed between centers or steady rests.
2. A corundum, diamond or CBN grinding wheel runs at 1,500–3,000 rpm.
3. Cylindrical parts rotate at 10–100 rpm, while flat parts move linearly on the machine table.
4. CNC systems control radial feed, axial travel and wheel speed.
