Our stainless steel CNC machining services

Penta Precision delivers high-quality stainless steel CNC machining services to engineers, manufacturers, and OEMs across the UK. We combine expert craftsmanship, advanced machining technology, and ISO 9001:2015 standards to produce reliable, custom stainless steel parts. Whether you're building prototypes or scaling production, we ensure your parts meet exact specifications.

Our CNC machining steel service is built for consistency and control. We use advanced CAD/CAM systems, automation, and a skilled team to maintain high quality across all quantities. You can rely on us for both rapid prototyping and large-scale production runs.

Every project receives individual attention from design to delivery. We offer design for manufacture advice to help optimise part performance and cost. Our stainless steel CNC machining service ensures you get parts that are right the first time.

Stainless steel milling

We provide CNC milling stainless steel parts to tight tolerances with outstanding repeatability. Our automated machining centres run around the clock to deliver parts efficiently and consistently. You benefit from fast turnaround and cost-effective production regardless of batch size.

Stainless steel is tough, but our team has the experience and tooling to handle it. We understand how to cut stainless steel cleanly while maintaining surface integrity and dimensional accuracy. Our process gives you precision parts that are ready for use.

We can work from CAD models, engineering drawings, or even sketches. Our CNC stainless steel milling capabilities are backed by modern CAD/CAM integration for full control. We deliver machined stainless steel parts that meet both functional and visual requirements.

Stainless steel turning

We produce stainless steel turned parts using multi-axis CNC lathes with 24-hour automation. Our process ensures consistency across single prototypes or high-volume production. You get stainless steel turning parts that are accurate, repeatable, and delivered on time.

Our team is skilled in both complex geometries and tight tolerances. Whether you need basic shapes or intricate designs, our stainless steel turning service meets the challenge. We offer excellent value through efficient setups and robust quality control.

Finishing Options

We offer a range of finishing processes to improve the appearance, durability, and function of your machined stainless steel parts. Each finish is selected to suit the application and performance requirements of your project. You can count on us for complete, production-ready components.

Available finishes include polishing, bead blasting, and passivation. We also offer part marking, deburring, and other secondary processes. All finishing is performed to industry standards with full inspection.

Components & applications

We machine stainless steel parts for a wide variety of industrial uses. Our components are used in environments where strength, hygiene, or corrosion resistance are critical. We work closely with customers to ensure parts are fit for function and built to last.
