contact wheel मीनिंग इन हिंदी

In the wide belt method, a contact wheel supports the abrasive belt.
Finishing generally requires the use of a smooth faced contact wheel and fine grade abrasives.
Stock removal generally requires a harder, serrated rubber contact wheel, and coarse grade ceramic abrasives.
The selection of the contact wheel and abrasive to match the grinding parameters required for a specific operation is very critical.
These include the work material properties, the grit and abrasive type of the grinding belt, belt speed, belt sequences, contact wheel hardness and diameter, serration, type of lubricant ( or dry ) and grinding pressure.
