Aluminium is one of the most widely used materials in precision machining, but consistent results still depend on the right equipment, tooling, inspection process and production control.
Penta Precision manufactures aluminium CNC machined components to exact specifications, helping customers reduce supply risk, improve part consistency and keep production moving.
From CNC milled aluminium housings and brackets to turned aluminium components and complex multi-axis work, our team supports parts that need accuracy, repeatability and reliable communication throughout the project.

Whether you need CNC milled aluminium parts, turned aluminium components or repeat production of complex assemblies, our machining capabilities are built around accuracy, consistency and dependable supply. We offer:




































Selecting the appropriate material and grade is among the important early decisions you'll make when designing your CNC machined component. In this blog we look at the most common grades of aluminium, one of the most versatile metals, and the factors to consider to select the best grade for your next project.
We can achieve tolerances as tight as ±0.01mm, depending on the complexity and requirements of the part. Our standard machining tolerance is ±0.1mm, which suits most applications. For critical components, we work closely with you to meet specific tolerance needs.
Lead times vary based on part complexity and order volume. Typically, we deliver prototypes within 1–2 weeks and production batches within 3–4 weeks. We strive to meet your project timelines and can accommodate urgent requests when possible.
Yes, we cater to both one-off prototypes and full-scale production runs. Our flexible setup allows us to efficiently handle varying order sizes. Whether you need a single part or thousands, we provide consistent quality and service.
Yes, we provide first article inspection reports and comprehensive quality documentation upon request. Our quality assurance processes are aligned with ISO 9001:2015 standards. This ensures traceability and compliance for all your machined components.
