When roll differential is set at the values closer to 1, dominant forces in grinding zone are compressive forces. With the elevation of the differential, greater shear stresses are imposed, which alters relative contribution of compressive and shearing forces.

Another benefit of crowning a roll is improved product quality. And more importantly, crowning helps the roll covering last longer, increases the rubber life, and helps reduce machine downtime. Assuring Results. Specifying a crown on a roller must be done with precision. This is especially true when grinding or cutting an accurate crown.

Flute grinding solid carbide mills: 6 to 12 mm 3 /mm/s; These values depend on the stiffness of the machine tool, the fixturing of the workpiece, the hardness and the microstructure of the material to be ground. If possible, work in down-grinding mode as it generates lower forces that, in turn, reduce the risk of burning and flexing of the ...

Grinding of mill rolls is carried out with chatter resistant abrasive grinding wheels having relatively low elastic modulus values and relatively high burst speed values. Grinding operations may be carried out at high efficiency with controlled wheel vibration, thus generating optimum surface quality on the ground mill rolls.

For example, iron rolls will have higher removal rates than a material such as HSS, which will have lower values during testing. Testing should be performed with a roll that has been ground after mill use to ensure the "mill hard" surface has been removed prior to the grinding …

Besides, we can save a damaged roll by copying its surface and after grinding, etching it with the same design adapted to the new diameter. Technical Sheets Thanks to special reading and gauging devices, we can measure samples values reproducing them on metal with the same roughness/ gloss, and providing the relevant technical form at the end ...

It measures the roll with great precision, using 360 values per revolution. Measuring takes place both before and during the grinding process. If the roll rotates slowly, an average value is formed from the raw data, which accrue at a high temporal resolution of 1 ms. This averaging improves the quality of the measured data yet again.
