Product Description
Custom OEM High Precision CNC Turning and Milling Machined Parts
Product Overview

Our CNC turning and milling composite parts are custom-manufactured for clients who demand both rotational precision and complex prismatic features in a single component. By combining turning and milling operations within one clamping setup, we eliminate positioning errors that accumulate when parts are transferred between separate machines.

Every part is produced to your exact drawing specifications, with micron-level tolerance control and full traceability throughout the production process. From single-piece prototypes to high-volume production runs, we deliver consistent quality that meets stringent European and North American OEM requirements.

Product Details

These composite-machined parts integrate rotary features—including outer diameters, internal bores, tapers, threads, and seal grooves—with milled features such as flat sides, keyways, cross holes, mounting faces, and irregular contours. All features are machined in a single setup, ensuring perfect geometric alignment between turned and milled surfaces.

Unlike parts produced on separate machines, our composite machining process maintains strict concentricity, perpendicularity, and positional accuracy without tolerance stack-up. Every part undergoes full deburring and edge breaking, leaving smooth surfaces free of tool marks, burrs, or sharp edges.

We accept 2D drawings, 3D models, and physical samples for replication. Our engineering team provides DFM (Design for Manufacturing) feedback before production begins, helping optimize part geometry, reduce costs, and shorten lead times without compromising functional performance.

Key Features
  • Single-setup composite machining for complex geometries that cannot be produced on a single machine
  • Micron-level tolerance control ensuring interchangeability in high-precision assemblies
  • Wide material selection covering ferrous, non-ferrous, and engineering plastic materials
  • Smooth, burr-free surfaces with customizable finish and treatment options
  • Full customizability—no standard catalog, every part is built to your specification
Product Advantages
Higher Geometric Accuracy

One-time clamping eliminates repositioning errors between operations. Concentricity, perpendicularity, and positional accuracy are consistently maintained across every feature.

Reduced Production Lead Time

Consolidating turning, milling, drilling, and tapping into one setup reduces machine changeover time and material handling, shortening overall production cycles.

Lower Total Cost

Fewer setups, less handling, and higher first-pass yield reduce labor and overhead costs. Complex parts are produced efficiently under one roof.

Scalable from Prototype to Production

We support single-piece prototypes for design validation, small-batch runs for testing, and high-volume production—with consistent quality standards at every scale.

Strict Quality Control

All parts undergo in-process and final inspection using calibrated equipment. Full inspection reports (FAI/PPAP) are available upon request.

Application Scenarios
  • Automation Equipment: Precision shafts, linkages, actuator components, and mounting brackets
  • Fluid Control: Valve bodies, hydraulic fittings, pneumatic connectors, and manifold components
  • New Energy Vehicles: Motor shafts, battery cooling fittings, high-voltage connector housings
  • Medical Devices: Surgical instrument components, implant bases, and precision valve parts
  • Packaging Machinery: Conveyor rollers, timing pulleys, custom spindles, and guide components
  • Robotics: Joint shafts, reducer components, end-effector adapters, and structural fittings
Frequently Asked Questions
What file formats do you accept for custom orders?
We accept DWG, DXF, PDF (2D drawings), STEP, IGES, and STL (3D models). Please include material specification, tolerance requirements, and surface finish instructions with your submission.
Can you produce parts with tolerances tighter than ±0.003mm?
Yes, ultra-precision tolerances down to ±0.001mm are available for selected features and materials. Please specify critical dimensions on the drawing and our engineering team will confirm feasibility.
Do you provide surface treatment and heat treatment in-house?
We work with certified partner facilities for anodizing, plating, passivation, and heat treatment. All treatments are performed to your specification and inspected before shipment.
What is your typical lead time for prototype and production orders?
Prototype orders (1-10 pcs) typically ship within 3-5 working days. Production orders depend on quantity and complexity, usually 7-20 working days. Expedited service is available.
How do you handle quality issues after delivery?
We stand behind every part we ship. If any part fails to meet drawing specifications, we will replace it free of charge or issue a full refund. Our quality team investigates every non-conformance.
