Automatic Bar Machining

Machining Parts from 1/16″ to 2 5/8″

Automatic Bar Machining refers to the automatic cycling of the screw machines along with the simultaneous feeding the raw material (bars) for fast, reliable & efficient production. At Avanti, our knowledgeable and experienced staff sets us apart from our competition. We know our customers rely on us to provide the highest quality screw machine products to spec and on time. In addition, we provide a full variety of secondary services which offers the ability to complete most component part applications in house.

INDEX CNC Multi-Spindle Features:

  • Fully configurable to meet complex requirements for custom parts
  • 6 main spindles with up to 2 swiveling synchronous spindles enable parts to be machined to precise specificiations
  • Extremely fast swiveling synchronous spindles with C-axis
  • Swing arm is locked in machining position for maximum rigidity

We understand the role that our machined parts play in the overall manufacturing assembly process. We respond and adapt with the changing needs of our customer’s maching demands.  The versatility of the INDEX CNC Multi-Spindle equipment enables us to support our customers with machined parts with both speed and accuracy.
