Primary Equipment
The Davenport 5-Spindle Automatic Bar Machine is designed to offer a cost-effective means for high-volume production of close tolerance parts turned from a bar. Throughout the industry, the Davenport is widely considered to be the fastest, most versatile multiple-spindle automatic bar machine ever built. These machines have the capability of performing multiple machining operations within the cycle time of the machine. This capability eliminates the need for costly secondary operations. The machining capabilities and features of the Davenport include:

• Thread Rolling
  • Conventional Tapping   • Cross Drilling
  • Countersinking
• Thread Cutting • Bent Shank Tapping • Cross Tapping • Counterboring
• Slotting • Milling • Broaching • Deburring
• Knurling • Reaming • Back Drilling  

• Bar Stock Capacity*
- Round bar starting at .0937" [2.38mm] up to .8125" [20.64mm]
- Hex bar starting at .125" [3.18mm] up to .625" [15.87mm]
- Square bar starting at .125" [3.18mm] up to .5625" [13.89mm]

• Material Capability*
Free machining grades of Aluminum, Brass, Bronze, Copper, Carbon Steel and Stainless Steel. The most common grades are Aluminum 2011T3, Brass Alloy 360, Steel C1215 & C12L14, Stainless Steel Alloys 203, 303 & 416.

• Part Length Capability*
Starting at approximately .0625" [1.59mm] up to 2.500" [63.50mm]

• Tolerance Capability*
Lengths as close as ±.002" [0.05mm]
