MULTI-SPINDLE MACHINING

Multi-Spindle Machining

Orrco’s multi-spindle machining capabilities allow us to produce high-volume, precision screw machine products efficiently and cost-effectively. Using a variety of National Acme multi-spindle machines, we support industries including mining, construction, valve manufacturing, lawn & garden, electronics, communications, and hydraulics.

National Acme Multi-Spindle Screw Machines

Our 6- and 8-spindle National Acme bar machines are designed for precision machining of components with diameters ranging from 1/4″ to 4″. These machines allow multiple operations to occur simultaneously, significantly reducing cycle times while maintaining exceptional quality.

Materials we machine include:

• Steel
• Brass
• Aluminum
• Stainless steel
• Copper
• Plastic resins

Advantages of Multi-Spindle Machining

Multi-spindle Acme machines give Orrco a competitive advantage for high-volume production:

• Turning and drilling performed simultaneously in the same spindle position
• Production time reduced to the longest single operation
• Faster output at lower per-part cost
• High precision and superior surface finishes
• Excellent repeatability for long production runs

Typical tolerances achieved:

• Diameters: ±0.0005″
• Lengths: ±0.001″
• Concentricity: ±0.001″ T.I.R.

Secondary Operations & Capabilities

Our experienced screw machine operators provide consistent quality across large production runs and support a wide range of secondary operations, including:

• Drilling and back drilling
• Form turning and recessing
• Knurling and shaving
• Tapping and thread rolling
• Reaming and broaching

High-Volume & Short-Run Production Solutions

Whether your order is large or small, Orrco engineers the right multi-spindle solution for your needs. Our quick-change tooling strategies reduce setup time, making multi-spindle machining viable even for shorter production runs.

By minimizing the ratio of setup time to production time, Orrco helps lower total manufacturing costs.

For continuous, high-volume production, multi-spindle machining remains one of the most efficient and reliable manufacturing methods available.
