Precision Turning

Precision CNC Turning Services

CNC turning utilizes computerized controls to precisely remove material from a rotating workpiece by regulating cutting tool speed, tool path, and material feed rates to produce highly precise parts. It is ideal for aerospace, defense, oil and gas, and other mission critical commercial applications that require extremely high levels of accuracy.

At Parts Tool & Die (PTD), our precision CNC turning capabilities are built for OEMs and engineers who need accuracy, repeatability, and dependable lead times, even for their most challenging components. With decades of experience serving the aerospace, defense, oil & gas, industrial, and commercial sectors, we specialize in turning mid-to-high complexity parts in low-to-high volumes.

Whether your project calls for ultra-tight tolerances, exotic materials, or large diameter CNC turning, as an AS9100, ITAR and ISO 9001 certified company, we deliver parts that meet the highest quality standards while keeping your project on schedule and on budget.

From CNC lathe operations for high-precision small components to vertical lathe machining for large-format parts, our skilled machinists and advanced equipment make the impossible possible. And because we view every project as a partnership, our engineering-minded team works alongside yours to optimize manufacturability, cost, and performance.

How to Choose a Supplier for Precision CNC Turning Supplier

Partnering with a new precision CNC turned parts supplier means more than finding the right machinery – it’s about working with a partner that can deliver consistently, accurately and reliably. While many shops offer turning services, fewer are equipped to meet the demands of tight-tolerance, mission-critical applications across aerospace, defense, energy, and industrial markets.

When evaluating a supplier, consider their strength in the following areas:

Precision Expertise – A strong understanding of turning geometry – including tight concentricity control, long-length stability, and consistent finishes across shafts, housings, fittings, and threaded parts.
Certified Quality – In-place, proven quality systems certified by third-party organizations, such as ISO 9001:2015, AS9100:2016 for aerospace application, and ITAR compliance for defense programs.
Advanced Equipment – CNC turning capabilities that extend beyond basic lathes, including multi-axis turning centers with live tooling, as well as vertical and horizontal turning systems capable of producing both small precision components and large-diameter parts.

Engineering Support – Design for manufacturability (DFM) expertise that helps refine tolerances, simplify setups, and reduce machining time - especially for complex turned parts with multiple features.
Verifiable Compliance  – In-process probing, CMM inspection, and optical measurement systems to maintain dimensional accuracy - not just at final inspection, but across the machining process.
Part Traceability – the ability to track part details including raw materials, production processes, and equipment used to ensure accountability and compliance – which is especially important for highly-regulated applications, such as DoD and aerospace CNC turning.

PTD brings these capabilities together to support customers from prototype through production, delivering precision CNC turned components manufactured for performance and reliability. Contact us to discuss your application and requirements.
