Milling

Dura-Bar offers cold finished milling as an added service for rectangular and square bars. Many sizes are available from stock, and additional sizes can be custom ordered.

Some benefits of close tolerance bars include:

  • Eliminating rough milling operations
  • Sizing or locating for fixtures and tombstones
  • Removing the as-cast surface to increase insert life

Duplex Milling

Duplex milling offers the advantage of milling two sides of a product in one operation for additional cost efficiencies.
