A Legacy in Every Metal Chip: Preparing to Celebrate 80 Years of Precision Manufacturing
December 12, 2025Celebrating 80 Years of Precision Machining at Orrco
Few companies reach the milestone of eight decades in continuous operation. This January, Orrco celebrates its 80th anniversary—an achievement that reflects not only longevity, but an unwavering commitment to precision, quality, and partnership.
As a third-generation, family-owned manufacturer, Orrco offers something increasingly rare in today’s supply chain: the stability of time-tested craftsmanship paired with the advanced capability of modern CNC technology. Over 80 years, we have evolved strategically to serve as a single, trusted source for everything from high-volume production to complex, tight-tolerance components.
The Heritage: Three Generations of Commitment
Orrco’s story began in 1946, founded on the simple, powerful idea that American industry demanded reliable, high-volume precision parts. Our founder, Tom M. Orr., established the earliest standards of excellence using dependable screw machines, cementing our reputation in the post-war era.

- The Second Generation – Tom M. Orr’s sons, Tom and Keith Orr, recognized the accelerating pace of technology, strategically investing in the very first CNC machines and custom rotary transfer machines in the 1980s. They embraced the future while honoring the high-volume efficiency of our past.
- The Third Generation – Keith Orr’s daughters, Kelly McCambridge and Kathleen Orr, continue this legacy today. They are actively driving investments in multi-axis automation, digital quality control, and lean manufacturing processes.

The Foundation: The Enduring Art of Multi-Spindle Screw Machining
The bedrock of our history lies with the multi-spindle screw machine. For decades, the high-volume production of brass, steel, and aluminum components required the intricacy of cam changes and manual tooling adjustments. While many processes are now digitized, our mastery of these machines remains a core technical advantage.

The Multi-Spindle Advantage Today:
The inherent efficiency remains unmatched for high-volume orders. For parts that power industries from automotive to fluid control, where consistency across millions of units is mandatory, our decades of mastery translate directly into:
- Superior Efficiency: Performing multiple simultaneous operations for the highest throughput.
- Cost Optimization: The most economical production method for large quantities.
- Proven Repeatability: Eight decades of knowing how to make the 10,000th part as precise as the first.
The Evolution: Mastering Multi-Axis CNC Mill-Turn
The greatest strategic shift in our history was the transition to complex CNC machining. This leap required significant capital and re-skilling of our workforce – a major undertaking for any family business. Today, our sophisticated CNC Bar machines are the proof of that vision, allowing us to produce components for critical applications like medical devices and aerospace assemblies.
The Technical Leap
| Manufacturing Attribute | Multi-Spindle Screw Machines | CNC Mill-Turn Centers |
|---|---|---|
| Best Application | High-volume, repeatable production | Complex, low, mid, and high volume components |
| Setup Strategy | Optimized cam-driven setups for long runs | Single-setup, multi-axis flexibility |
| Cost Efficiency | Lowest cost per part at high volumes | Cost-effective for complex geometries |
| Tolerance Capability | Excellent and highly repeatable in production | Extreme precision to tight tolerances |
| Geometry Strength | High-speed precision turning | Complex contours, cross-holes, threading |
| Ideal Use Case | Millions of identical parts | Highly engineered components |
Orrco maintains both multi-spindle screw machines and CNC bar machines because each excels in different manufacturing scenarios. Precision is not about the newest machine. It is about using the right technology for the part.
