Advantages and Benefits

Advanced manufacturing capabilities with lean manufacturing flow

As the aerospace industry’s solution for hydraulic spool and sleeve assembly and testing, we’ve created an efficient value stream for manufacturing spools and sleeves, ultra-precision lap fitting, and hydraulic and pneumatic testing.

Hone-built precision with production speed

When your diameters are under 40mm, look to honing for fast production with greater accuracy and consistency than traditional I.D. grinders.

Inspection, testing, and validation

A crucial part of our Quality Management System, all parts are stringently tested before ever connecting to your aircraft. Each part is tested for precise form parameters such as roundness, concentricity, and cylindricity.

Trusted by industry leaders

Don’t take our word for it, trust those who trust us: Honeywell, GE Aerospace, Parker Aerospace, Precision Aerospace, and more. For nearly 40 years, we’ve been a leader in the global aerospace industry by maintaining an investment in both performance-driven machining and quality-driven personnel.
