Our turn-mill combined machining services deliver precision-machined components with complex features completed in a single setup. By integrating CNC turning and milling operations on advanced multi-axis machines, we achieve exceptional accuracy with tolerances as tight as +/-0.01mm while eliminating the tolerance stack-up errors common in multi-operation machining.
We specialize in complex components that require both rotational turning features and prismatic milling features. This includes valve bodies, hydraulic fittings, sensor housings, fluid connectors, and custom mechanical assemblies. The turn-mill process enables features such as precision external and internal threading, multi-diameter turning, square or hexagonal flats, cross-drilled holes, and complex port geometries - all in one setup.
Components are manufactured from premium materials including stainless steel 304 and 316 for corrosion resistance, carbon steel and alloy steel for high-pressure applications, and brass for fluid handling components. All materials are sourced from certified suppliers with full material certificates and traceability documentation provided with every shipment.
Our ISO 9001:2015 certified quality management system ensures consistent quality across every production run. Each part undergoes rigorous dimensional inspection using coordinate measuring machines (CMM) and optical comparators. Thread accuracy is verified with calibrated thread gauges, and surface finish is confirmed with profilometers to ensure specifications are met.
These turn-mill combined components serve critical applications across hydraulic systems, pneumatic equipment, fluid control valves, instrumentation, process control, and industrial automation. Common applications include pressure valve bodies, flow control fittings, manifold blocks, sensor mounting bodies, and custom assemblies requiring both rotational and prismatic features.
We support your complete product development cycle with flexible manufacturing options. Validate designs with rapid prototypes, refine through small batch testing, and scale to high-volume production with confidence. Single-setup machining reduces lead times and improves consistency compared to traditional multi-operation manufacturing methods.

FAQ
Q: What are the advantages of turn-mill combined machining?
A: Turn-mill machining combines turning and milling operations in a single setup. This eliminates multiple fixturing operations, reduces tolerance stack-up errors, decreases lead times, and often reduces overall cost for complex parts requiring both rotational and prismatic features.
Q: What thread standards can you machine in turn-mill operations?
A: We machine all standard thread forms including metric (M), unified (UNC/UNF), pipe threads (NPT/BSPT), and British Standard threads. Internal and external threads are verified with calibrated thread gauges to ensure compliance.
Q: What materials do you typically work with?
A: We work with stainless steel (304/316), carbon steel, alloy steel, brass, copper, and aluminum. Material certificates and full traceability documentation are provided with every shipment for quality assurance.
Q: Can you achieve complex port geometries in valve bodies?
A: Yes, our turn-mill capabilities enable complex internal port geometries including cross-drilled passages, angled holes, and multi-port configurations. We can machine up to 5-axis simultaneous paths for intricate flow paths in valve bodies and manifold blocks.
Q: What is your minimum order quantity?
A: We accept orders from 1 piece for prototype validation. No strict MOQ - we support one-piece prototyping, small batch production for testing, and large-scale manufacturing with consistent quality and competitive pricing.
Q: What is your typical lead time for turn-mill parts?
A: Prototype samples: 3-7 days. Small batch (10-100 pcs): 7-14 days. Medium batch (100-1000 pcs): 14-21 days. Mass production: 21-30 days depending on quantity and complexity. Single-setup machining often reduces lead times compared to multi-operation processes.
