Roll Grinding is a specialized form of cylindrical grinding and precision grinding of various kind of rolls. Roll grinding wheels are used in the re-grinding and production grinding of rolls for the Steel, Brass, Copper, Aluminium, Printing paper and textile industries. Most roll grinding wheels are type 1, 5 or 7 ranging from 14" (355mm) to 42"(1065mm) diameter and 1.1/2(38mm) to 6"(150mm) thickness. Also, the bonding material is normally Resinoid Bonded but some times Vitrified Bonded wheel is used. The general hardness is from "F" to "N" and most common grit size is from #24 to #120 but it depends on the grinding conditions.
Technical tips
The grade of the wheel depends on the horsepower of the machine and the material being ground.
In general, duel wheel grinders require softer grades than single wheel grinders.
A soft grade wheel reguires hard materials than soft materials.
