Our bronze CNC machining services

Bronze is valued for its strength, corrosion resistance, and excellent wear properties, and we machine it with care. At Penta Precision, we offer CNC machining services for bronze parts that demand accuracy and durability. Whether it’s a small prototype or a large production batch, our team delivers dependable bronze components to meet your application needs.

We combine modern CNC automation with expert human input for accuracy and repeatability. Our team understands the unique properties of bronze and adapts processes accordingly. You get consistent quality whether you're machining aluminium bronze or working with softer copper alloys.

Our customers include manufacturers in marine, electronics, and architecture sectors. We deliver CNC bronze parts for both functional and decorative uses. You benefit from expert advice, clear communication, and parts delivered on time.

Bronze milling

We provide milling bronze parts using high-precision 3- and 5-axis machining centres. Our automated equipment runs continuously to deliver fast turnaround and excellent consistency. Whether it’s complex internal features or flat surface details, we machine to your requirements.

Our team is experienced in machining aluminium bronze and similar alloys. These materials are tough but rewarding when machined correctly. We select tooling, feeds, and cutting strategies to maintain part integrity and surface quality.

You can supply CAD models, engineering drawings, or even simple sketches. We’ll convert your idea into a precise, production-ready component. Our CNC machining bronze service ensures you get bronze precision parts with tight tolerances and clean finishes.

Bronze turning

We manufacture high-quality turned bronze components using multi-axis CNC lathes. These machines allow for complex shapes, accurate dimensions, and repeatable results. From custom bronze parts to large batch production, we meet the challenge.

Our team supports both one-off and high-volume orders. With efficient setups and refined processes, we produce bronze turned parts with speed and reliability. You receive parts that are ready to use, straight from the machine.
