Our History and Growth

Lock-Ridge Tool was founded in 1962 as a tool and die shop focused on high-precision machining. Over the decades, we expanded our capabilities to meet the evolving needs of industrial and aerospace manufacturing.

  • Expansion into metal fabrication – Recognizing the demand for high-quality production, we incorporated punch presses and stamping equipment, allowing us to support high-volume manufacturing.
  • Adopting advanced CNC machining – The introduction of 4-axis CNC milling and turning enhanced our ability to produce complex, high-tolerance components for critical applications.
  • Automation and efficiency – We implemented robotic welding, unmanned stamping, and laser cutting, which increased production speed, consistency, and cost-effectiveness. 
  • Enhanced quality assurance – Our FARO arm with scanner enables us to compare models to actual production parts, ensuring precise accuracy and consistency.
