Precision CNC Turning & Turn-Mill Machining Services
PRECI5 operates a high-precision manufacturing facility in Shenzhen, China, engineered for complex shafts, sleeves, bushings, and geometric rotational components. Leveraging single-setup turn-mill machining, we achieve verified machine positioning down to 0.003 mm with repeatable volume stability.
Integrated multi-axis turn-mill machining eliminates cumulative re-chucking errors for concentric shafts and complex turned parts.
Integrated Turn-Mill Machining for Intricate Rotating Parts
Modern mechanical engineering projects consistently exceed the constraints of traditional 2-axis CNC lathe machining. At PRECI5, our production floor integrates live tooling and turn-mill machining in China, executing dual-discipline operations on cylindrical profiles without part transfer.
By unifying turning with secondary milling operations—such as radial cross-holes, axial keyways, milled flats, multi-pitch threading, and eccentric bores—in a single continuous setup, we eradicate cumulative clamping variations. This methodology guarantees concentricity, precise pitch alignment, and high dimensional accuracy for mission-critical assemblies.
- Complex Cylindrical Geometries: Optimized for transmission shafts, planetary gear carriers, connector housings, and valve sleeves.
- Reduced Lead Times: Streamlined direct routing removes queue bottlenecks between separate turning and milling departments.
- Strict Concentricity Control: Critical journal bearing fits, snap-ring grooves, and seal faces stay true to common datum axes.
High-speed rotor shafts and stepped spindles with controlled total runout and cylindrical form requirements.
Thin-walled bushings and bearing sleeves with internal oil grooves and fine micro-inch bore finishes.
Spools, poppets, and manifold fittings requiring precision sealing tapers and micro-deburred cross-holes.
Custom threaded studs, coupling nuts, and aerospace pins machined across standard and exotic alloys.

Metrology Laboratory and Engineering Assurance
Precision CNC turning requires continuous in-process gauging and certified lab verification. Explore our metrology capabilities and engineering review controls.
Dimensional Verification
ZEISS Coordinate Measuring Machines (CMM) and high-resolution 2.5D optical measuring systems validate complex geometries.
Geometric Runout & Concentricity
Specialized bench centers, dial indicators, and concentricity testers ensure radial runout meets tight drawing limits.
Surface Roughness Validation
Calibrated contact surface profilometers measure Ra, Rz, and Rq across sealing faces and bearing journals.
Alloy Composition (XRF)
Handheld X-ray fluorescence spectrometers inspect raw bar stock on delivery, confirming chemical alloy consistency.
Hardness Testing
Rockwell and Vickers hardness testers verify that case hardening, induction hardening, or nitriding meets technical notes.
Documentation & Traceability
Standard delivery packages include full FAI (First Article Inspection), material mill certificates, and CMM dimension logs.
Pre-Machining Engineering Review
Before toolpaths are generated, our engineering department reviews your 2D drawings and 3D CAD files. We check geometric dimensioning and tolerancing (GD&T), assess corner radii, evaluate thread pitch standards, and identify deep groove tool clearance challenges.
Toolpath & Deflection Analysis
For slender shafts and thin-walled parts prone to vibration or deflection, we optimize tailstock support, steady rest placements, and sub-spindle synchronized transfers to maintain uniform tolerances over total lengths up to 500 mm.
Stainless & Steels
304, 316L, 17-4PH, 4140, 4340, 12L14, and tool steels (D2, O1) for high wear, structural, and corrosive environments.
Aluminum & Non-Ferrous
6061-T6, 7075-T6, 2024, C360 Brass, phosphor bronze, and copper for thermal dissipation, weight, or bearing applications.
Engineering Plastics
POM (Delrin), PEEK, PTFE, Nylon, and UHMW-PE turned with customized rake tooling to avoid stress deformation.
Scalable Production Infrastructure for Industrial OEMs
PRECI5 provides Tier-1 and Tier-2 engineering supply chains across robotics, automotive, industrial automation, and fluid power sectors. Our manufacturing ecosystem integrates quality systems certified under ISO 9001, IATF 16949, and AS9100D.
Whether you need low-volume prototype verification or scheduled batch releases under blanket purchase orders, our 22 Mazak machines offer flexible spindle allocation to keep your delivery timelines secure.
