Centerless Grinding and Turning

Centerless Grinding

Dura-Bar provides precision grinding of bars for demanding-tolerance applications. Many grades and sizes are available from stock. Many others can be custom ordered.

Some benefits of close tolerance bars include:

  • Saving or even eliminating machine time
  • Sizing for certain collets or bar feed equipment
  • Removing the as-cast surface to increase insert life
