Precision Machining & Grinding Tight Tolerances. Perfect Finishes. Ready-for-Service Components.
Precision machining and grinding are core elements of our engineered remanufacturing process. Whether we’re restoring hydraulic rods, spindles, shafts, or industrial rollers, our team ensures exact dimensions, surface finishes, and geometric tolerances—delivering components that meet or exceed OEM standards.
Unlike general-purpose machine shops, our machining capabilities are built around remanufactured surfaces—accounting for weld overlays, chrome plating, and thermal spray coatings. Every cut, turn, and grind is performed with reman performance in mind.
From large-diameter rollers to complex shafts and pins, we provide high-precision solutions that get your equipment back to work—fast.

Precision Machining & Grinding FAQ Topics
What are your maximum diameters and lengths for turning and grinding?
We can turn components up to 60 inches in diameter and 200 inches in length, depending on the geometry and setup. Our precision grinding capacity extends to 32 inches in diameter and 32 feet in length, accommodating large hydraulic rods, rollers, and shafts.
What tolerances can you achieve?
Our precision grinding and machining tolerances are typically inside of 0.001 inch, ensuring accurate geometry and consistent performance across critical bearing, sealing, and fit surfaces.
What surface finishes (Ra) are typical for plated or coated parts?
We routinely finish plated and coated components to 4–12 Ra microinch, with superfinishing and mirror polishing available for specialized applications such as hydraulic rods and high-speed rollers.
Can you machine overlayed or coated surfaces?
Yes. We specialize in precision machining and grinding of weld overlays, hard chrome, and thermal spray coatings. Our equipment, tooling, and process parameters are optimized to maintain coating integrity while achieving required tolerances and finishes.
How do you measure and verify geometry before and after machining?
We perform pre- and post-machining dimensional verification using calibrated and precision inspection instruments.
