When it comes to machining impellers, there’s no room for error. These high-performance components are critical to the function of pumps, compressors, turbines, and other rotating equipment. From industries such as aerospace, energy, defense, and other industrial applications, we offer the highest quality 5-Axis Impeller CNC-Machining Services for Original Equipment Manufactuers in the United States. With our advanced technologies, skilled team, and on-site inspection lab, Precise Tool & Manufacturing doesn't just make impellers, we specialize in them, with experience machining sizes ranging from 8 inches to 49 inches in diameter, in a variety of metals. We offer you performance, repeatability, and uncompromising quality.
Precision Starts with the Right Machines
Our impeller machining capabilities are powered by a lineup of advanced MAZAK 5-axis CNC machines available:
-
(3) VARIAXIS i-600
-
(2) VARIAXIS i-700
-
(4) VARIAXIS i-800 NEOs
-
And now, the latest addition: the MAZAK VARIAXIS i-1050—a machine that extends our max diameter capacity to 49 inches and up to 4,000 lbs per part.
Whether you're producing a compact high-speed impeller or a large-diameter unit for industrial flow systems, we have the right equipment to handle the complexity—and the weight.
New Video: A 14-Inch Steel Impeller, Start to Finish
On our blog page, you’ll find our latest video featuring Jeff Hartman, one of our veteran machinists with over a decade of experience, walking through the full machining process of a 14-inch steel impeller. From setup and fixturing to multi-axis cutting and final inspection, the video highlights:
-
Tight tolerance control
-
Complex multi-blade geometries
-
Surface finish accuracy
-
The craftsmanship and precision we bring to every job
Jeff’s attention to detail and deep experience reflect how we approach every impeller we produce—meticulous, reliable, and application-ready. Moreover, our on-site quality control lab which features 5 Coordinate Measuring Machinse (CMMs) means we don't offer you a "trust me", we prove your tolerances and requirements are met exactly.
Material Versatility. Industry Flexibility.
Impellers aren’t one-size-fits-all, and neither are our capabilities. We work with a wide variety of materials including:
-
Stainless steels
-
Alloy steels
-
Titanium
-
Aluminum
-
And more
No matter the industry or design spec, we adapt our process to meet your needs—whether you require tight concentricity, balanced performance, or smooth-flow geometries. We thrive on complexity and take pride in hitting the tolerances others shy away from.
Built for OEMs Who Need It Done Right the First Time
We partner with OEMs across the U.S.—from New York, Pennsylvania, and Ohio to nationwide customers—who need more than just a machine shop. They need a partner who understands the critical function of each part, who offers traceable quality, and who delivers parts ready for real-world performance.
