Since 1966, Buell Automatics has been designing and manufacturing small precision products for a wide range of industries and applications. Our over 50 Davenport multi-spindle screw machines, in particular, offer unique versatility thanks to their distinctive features designed and developed by our team.Davenport Components

  • High Pressure Coolant-Through Drilling: Designed for deep hole applications for almost any material. Results in faster cycle times, ability to produce more complex parts and all at a lower cost than our competitors.
  • PATENTED Short Part / Broken Tool Detection: System insures when a short part or broken tool is detected the machine stops and the custom divertor chute sends the suspect parts away from good parts. The best part is the machine won’t run unless the system is working correctly!
  • Sensi-Buell MRP Software: Designed and developed by our team to ensure tools are changed before they fail, provides real quality and production performance to our employees, inventory control for tools and efficiency information for quoting. Ensures the quality and consistency our customers expect!
  • Machine Rebuilding: All our machines are rebuilt to OEM or better standards to ensure our quality and engineering standards are consistently met. Well maintained machines make for happy employees as well as productive employees.
