A roll grinder is usually installed in aluminium, paper or steel mills to grind textured and smooth rolls. Roll grinding involves external cylindrical grinding between centres. The machined rolls are much larger than conventional workpieces, so they require very large roll grinding machines that can withstand enormous vibrations.
- Roll grinding machine are in general massive and voluminous components of larger machines and tools
- For pressing rollers, the surface of the roll grinding machine is the deciding factor in quality
- Guide roll grinding machines have specific quality requirements

Roll grinders are very large component parts of various metalworking production lines. The rollers these machines create are used to move oversized workpieces - often between one work area and another. A quality roll grinder always has a perfectly smooth and rounded surface. This is essential for the safe and controlled movement of workpieces. Any imperfections, bumps or dents could results in damage to the workpieces being moved. If the surface of a roll grinder machine contains an imperfection, there is a chance that the same imperfection will be passed onto the workpiece.
A roll grinding machine exerts a lot of pressure. A badly calibrated machine or even the slightest of imperfections in a roller not only has the potential to damage the workpiece, it can also bring an entire production line to a halt. In many production lines, the quality of rollers in use has a direct impact on the final products created - so they have to be perfect and operating correctly at all times.
