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]
Diameters as close as ±.001" [0.025mm]

Quality control at Tri-Star Industries. Quality: All parts produced at Tri-Star Industries have been identified with critical-to-function features. These features are prominently noted on all part prints. Data is collected electronically on the production floor with a leading SPC software program. Operators are trained in the use of all SPC software, hardware and measuring instruments. The production floor data collection system is networked, in real time, to the Quality Department to allow the Quality staff to monitor and control all activity of the SPC program.
Aqueous parts washing system cleans and dries all components manufactured at Tri-Star Industries. Parts Cleaning: A state-of-the-art, environmentally friendly, aqueous parts washing system cleans and dries all components manufactured at Tri-Star Industries. The computer-controlled system employs agitation, rotation, submersion, jet-spray and ultrasonic cleaning methods. Components are housed in stainless steel mesh baskets specifically designed to allow the parts to tumble during the cycle time. The system and the baskets allow for an extraordinary flow of fluids to flush the parts clean of cutting fluids, metal turnings and debris. A seven-chamber dryer assures that the parts are free of any and all moisture.
Laser Sorting: Where specified, high-volume automotive components and high-volume automated assembly applications are laser sorted to ensure 100% compliance on critical-to-function features. Common attributes include overall length, presence of thread or through-hole obstructions. Parts are bowl fed through a series of gates, traps and rails. The parts become oriented before they pass a series of laser beams, which identify the part as conforming or non-conforming. An electronic and air-activated diverter segregates any non-conforming product. An automatic packaging system is attached where the parts are laser counted as they enter the shipping container. Laser sorting to ensure 100% compliance on critical-to-function features.
