CNC Machining for Energy & Industrial Equipment
Valve bodies, hydraulic manifolds, flanges, and pump housings — machined from corrosion-resistant alloys for oil & gas, renewable energy, and power generation applications.

Energy equipment operates under sustained pressure, thermal cycling, and corrosive media. The difference between a seal face at Ra 0.8 µm and Ra 1.6 µm determines whether a hydraulic manifold holds 350 bar or leaks at 280. Material grade selection, machining strategy, and post-process surface quality are tightly coupled decisions that most prototype shops treat independently. KUSLA treats them as one problem.
Energy Sectors We Serve
KUSLA machines components across the energy value chain — from upstream oil and gas to renewable infrastructure. Each sector imposes different material, pressure, and environmental demands on machined parts.
Material Selection: Corrosion Resistance for Energy Environments
Energy components face aggressive media — saltwater, H₂S, high-temperature steam, caustic cleaning agents. Material selection drives 80% of a part’s service life in these environments. KUSLA machines all of the following alloys, with material certificates and heat lot traceability on every order.
Corrosion ratings represent general atmospheric and aqueous media performance. Specific media compatibility (H₂S, chlorides, acids) requires grade-level evaluation. Contact KUSLA engineering for application-specific material recommendations.
Valve Body & Hydraulic Manifold Machining Capabilities
Valve bodies and hydraulic manifolds are the most demanding energy components KUSLA machines. They combine deep intersecting bores, tight seal surface finishes, and pressure-rated materials — all of which require rigid fixturing, controlled feeds, and in-process verification.
| Specification | KUSLA Capability | Notes |
|---|---|---|
| Max part envelope | 800 × 500 × 400 mm | 5-axis machining center working volume |
| Intersecting bore depth | Up to 12× diameter (gun drilling available) | Deburring of internal bore intersections included |
| Seal surface finish | Ra 0.4–0.8 µm | O-ring grooves per ISO 3601, metal-to-metal seats per API 6A |
| Thread standards | NPT, BSP, SAE O-ring Boss (ORB), metric | Thread gauging and CMM verification |
| Port face flatness | ≤ 0.01 mm across 100 mm span | Critical for manifold stacking and O-ring sealing |
| Pressure test support | Hydrostatic test plugging and port preparation | Parts delivered pressure-test-ready; testing by customer |
| Post-machining treatments | Passivation (SS), anodize (Al), black oxide, electroless nickel | Surface finish guide → |
The trickiest energy parts we machine are 316L hydraulic manifold blocks with 6–8 intersecting bores at different angles. The internal bore intersection creates a burr that you can’t reach with a standard tool. We use a combination of cross-hole deburring tools and thermal deburring (TEM) for critical flow paths. Last quarter we delivered a batch of 24 manifold blocks for a solar thermal system — each block had 7 cross-drilled ports, seal faces at Ra 0.6 µm, and NPT threads on all ports. We held port-to-port positional accuracy at ±0.03 mm across the block. The client’s pressure test passed at 420 bar with zero leaks on first assembly.

Frequently Asked Questions
KUSLA machines stainless steels (303, 304, 316L, 17-4 PH, duplex 2205), alloy steels (4140, 4340), aluminum alloys (6061, 7075, 5052), titanium (Grade 2, Grade 5), brass, and engineering plastics (PEEK, POM). Material certificates with heat lot traceability are provided on every order.
Yes. KUSLA machines manifold blocks with up to 12 intersecting bores, using gun drilling for depths up to 12× diameter. Internal bore intersections are deburred using cross-hole deburring tools or thermal deburring (TEM). Seal faces are finished to Ra 0.4–0.8 µm, and port positional accuracy is held to ±0.03 mm.
NPT, BSP, SAE O-ring Boss (ORB), and metric threads are all supported. Thread gauging and CMM verification are performed on every batch. O-ring grooves are machined per ISO 3601 dimensions.
Every order ships with a dimensional inspection report and material certificate (mill cert with heat lot traceability). For critical applications, CMM reports with GD&T verification and first-article inspection (FAI) documentation are available on request.
Standard lead time is 7–12 business days for valve bodies and manifold blocks, depending on complexity and material availability. Simple brackets and mounting plates ship in 5–7 days. Aluminum parts for renewable energy applications typically ship in 5–8 days. Expedited service is available.
