Custom 5-Axis CNC Machining for Impellers, Housings, and Complex Parts
Specializing in build-to-print 5-axis machining for complex components. Our single-setup process delivers higher accuracy and shorter lead times by machining all features in one operation, eliminating the tolerance errors common in multi-setup work.
Core Multi-Axis Machining Capabilities
Utilizing the right multi-axis strategy—from full 5-axis contouring to 3+2 positioning—to ensure your part’s design integrity and dimensional accuracy.
Simultaneous 5-Axis Milling
Enables the machining of highly complex and organic geometries in a single, continuous toolpath, ideal for parts with sculptured surfaces and dynamic fluid channels.
Continuous Motion Complex Surfaces
3+2 Indexable Machining
An efficient method for machining multiple sides of a prismatic part in just two setups. Ideal for parts with deep pockets and angled features on different faces.
Prismatic Parts Fewer Setups
Complex Turn-Milling
Integrates both turning and milling capabilities to produce complex cylindrical parts with off-axis features in a single machine, drastically reducing setups and handling.
Turn-Milling Consolidated OpsEngineering & Buyer Advantages
Leveraging single-setup machining to produce higher quality parts, faster.
Complex Geometry Realization
Enables the machining of complex shapes, undercuts, and organic contours in one setup, expanding design freedom for parts like impellers and turbine blades.
Reduced Setups & Lead Time
A “Done-in-One” approach machines all part faces in a single operation, eliminating multiple fixture setups and manual handling to directly reduce project lead times.
Higher Part Accuracy
Eliminating re-fixturing prevents the tolerance stacking errors inherent in multi-setup processes. This results in higher dimensional accuracy and feature-to-feature precision.
Superior Surface Finish
Allows the use of shorter, more rigid cutters oriented optimally to the part surface. This minimizes tool vibration, producing a superior finish that can reduce or eliminate secondary polishing.
Quality Verification Sequence
A four-stage verification process to ensure every component meets blueprint specifications from raw material to final shipment.
Stock Audit
Verifies full material traceability by checking incoming stock against mill test reports (MTR) before releasing it to the production floor.
First Article
A full First Article Inspection (FAI) validates the entire manufacturing process against all drawing specifications before authorizing the full production run.
In-Process
In-Process Quality Control (IPQC) is conducted at critical stages to monitor key dimensions, ensuring process stability and preventing deviations during production.
Final Metrology
A comprehensive final inspection using calibrated metrology tools (e.g., CMM) generates a detailed report, confirming all dimensions conform to the engineering drawing.

Surface Treatment and Finishing Options
We manage a complete range of finishing options to meet your part’s cosmetic, protective, and functional requirements, delivering production-ready components.
Anodizing (Type II & III)
Creates a robust, corrosion-resistant surface for aluminum parts. Available as Type II for cosmetic finishes and Type III (Hardcoat) for maximum wear resistance.
Bead Blasting
Produces a uniform, non-directional matte texture. Ideal for removing tool marks and preparing surfaces for subsequent finishes, or as a standalone cosmetic treatment.
Passivation
A chemical process that maximizes the natural corrosion resistance of stainless steel by removing surface contaminants. This is a non-dimensional change process.
Powder Coating
Applies a durable and cosmetic layer available in a vast range of colors. Offers excellent resistance to impact, abrasion, and environmental exposure.
Questions Asked Before Sending a 5-Axis RFQ
How do you review tolerance risk on complex 5-axis parts?
We review tolerance risk feature by feature instead of applying one blanket tolerance to the entire part. The final acceptance criteria should be aligned with the geometry, material, and inspection plan for each critical feature.
Are material certificates and documentation automatically included?
Material certificates and quality documentation can be provided when they are requested and confirmed in the quotation scope. If your project needs MTR, CoC, or other records, include that requirement in the RFQ.
What’s the difference between 3+2 and simultaneous 5-axis machining?
3+2 machining positions the part at a fixed angle to machine specific features efficiently. Simultaneous 5-axis machining uses continuous motion and is better suited to complex contours and sculptured surfaces.
Is 5-axis machining always more expensive?
Not always. While machine time can be higher, a single-setup route may reduce fixture work, handling, and secondary setups, which can improve overall project efficiency.
Do you provide Design for Manufacturability (DFM) feedback?
Yes. We can review the design for feature feasibility, tool access, and risk points that may affect manufacturability or cost. DFM feedback is especially useful before quotation or production release.
What is the typical lead time for a 5-axis prototype?
Lead time depends on part complexity, material availability, and the scope of the request. For a more accurate schedule, send the 3D model, drawing revision, quantity, and target delivery date with the RFQ.
How do you ensure the confidentiality and IP protection of our designs?
We can work under NDA when required, and customer confidentiality is handled as part of the project process. If you need an NDA before technical review, include it with your initial inquiry.
What kind of inspection documentation can be provided?
Inspection documentation can be discussed based on project requirements and the level of verification needed. If you need FAIR, CMM data, or another format, specify that in the RFQ so it can be reviewed during quotation.
Submit Your RFQ Package
Send the key files and project details together so we can review the part, identify any open questions, and prepare a clearer quotation. If the design is still developing, include the current revision and mark the points that need manufacturability feedback.
