Custom Machine Work
Custom Machine Work
Flowell provides custom machine work and CNC machining for customers who need precision parts, repeatable tolerances, and reliable lead times. From one-off components to small production runs, we build to your print and your standards with a focus on dimensional accuracy, fit-up, and long-term performance in demanding service.
Many customers come to us because they need a shop that understands both machining and how parts perform in real flow and pressure systems. If your project ties into differential-pressure metering or process piping, we can help you align the part design with how it will be installed and used.
CNC Machining Capabilities
Our CNC machining capabilities support a wide range of work, including:
- Milling for complex profiles, pockets, and bolt patterns
- Turning for concentricity-critical diameters and sealing surfaces
- Drilling / tapping for instrument ports and mounting features
- Finishing support for surface requirements tied to fit, sealing, and performance
If you’re working on a flow measurement build, you may also want to review our Flow Measurement Products lineup to see the types of components we commonly support.
Materials We Commonly Machine
Material choice affects corrosion resistance, pressure rating, and long-term reliability. We commonly machine:
- Carbon steel for general industrial service
- Stainless steel for corrosion resistance and washdown environments
- Other alloys upon request based on media, temperature, and specification
Not sure what to choose? Send your media, temperature, pressure, and any spec requirements — we’ll help you pick a practical option and build to it.
Quality Control and Inspection
We take quality seriously because your parts need to assemble correctly and perform predictably. Our approach includes process checks and final verification for critical dimensions, features, and interfaces. If your project requires documentation, we can support common needs such as inspection verification and traceability requirements as part of your order package.
For engineering-driven projects, sharing clear drawings and acceptance criteria early helps prevent rework and keeps the schedule moving. If you need help defining a spec, we can walk through the application and recommend a practical tolerance/finish approach.
Where Custom Machining Helps Most
Customers use our machining support for parts that require tight control, repeatability, and clean fit-up, such as:
- Flow and pressure instrumentation components
- Metering and piping accessories with sealing surfaces
- Replacement parts to match legacy equipment
- Prototype components for new builds and testing
If your project relates to metering hardware, explore orifice plates and venturi tubes for examples of the types of precision components we manufacture.
How to Get an Accurate Quote
To move quickly, send:
- Drawing or sketch (PDF preferred) and revision level
- Material and any required certifications
- Quantity and target lead time
- Critical dimensions and inspection expectations
- Surface finish / coating requirements if applicable
If you’re not sure what to provide, just send what you have — we’ll clarify the details during quoting.
Standards reference: If your parts need to align with recognized dimensional and geometric practices, we can follow your site requirements. For general GD&T reference, see ASME’s overview of ASME Y14.5.
