CNC Machining

Milling, turning and drilling for industrial parts and equipment assemblies.

Operators working at machining centers in the ZJD workshop

For procurement & engineering teams

Is this the right process for your project?

Start here for drawing-defined faces, bores, threads and mechanical interfaces. Identify datums, critical tolerances and finish requirements; overall size alone does not establish whether a part fits a machine.

We machine individual parts and components for larger assemblies, with dimensional checks throughout production.

Typical outputs: Mechanical components · Pins, shafts and fittings · Machined brackets and interfaces · Production support parts · Components for larger assemblies.

Manufacturing example

Machined components

Customer-defined mechanical interfaces and individual equipment parts.

  1. Turning / milling: Create the specified component geometry.
  2. Secondary features: Complete drawing-defined holes, threads and interfaces.

Confirm before quotation: Part / drawing reference; Material / grade; Overall dimensions; Critical tolerances and datums; Surface roughness / finish; Heat treatment, if required.

Manufacturing example

Industrial cam locks

Locking and access interfaces for equipment panels, doors and enclosures.

  1. Component machining: Machine lock components to the agreed drawings and interfaces.
  2. Lock assembly and checks: Assemble the specified components and check fit and operation.

Confirm before quotation: Material; Panel thickness and mounting cutout; Lock-head and cam geometry; Operating direction; Surface finish; Functional inspection requirements.

Representative product types, not stock specifications or named customer case studies. Manufacturing scope and acceptance criteria are agreed for each project.

Turning

We turn shafts, fittings and round components to your drawing, then check the finished dimensions before release.

Key equipment: CNC lathes include CKG4650, CAK6185, CK6140H and HTC40B/500.

Materials & inputs

Carbon and alloy steels · Stainless steel · Aluminum · Other engineering materials subject to review

Working range

Parts from about 10 mm to 3,000 mm are assessed against machine travel, geometry and workholding. Material, tolerances and batch size are confirmed from the drawing.

Precision & quality control

Checked through production.

We check critical dimensions, component fit and the finished work against the drawing and inspection plan.

View inspection controls & certificates
  • Critical dimension review
  • Material and drawing traceability
  • In-process inspection
  • Final dimensional verification
  • Project-defined reports

Certificates support their stated management or process scope. Tolerances and acceptance criteria are confirmed for each part.

Before you request a quote

Can we discuss a project before sharing drawings?

Yes. Start with the application, approximate size, material and quantity. Detailed drawings can follow when you are ready for a technical review.

Discuss your project

Can you provide inspection reports in English?

Chinese original inspection and test reports with English translations are available on request. The report scope and acceptance criteria are agreed before production.

Quality documentation

Do you accept third-party inspection?

Yes. We welcome your nominated inspection organization and agree the inspection scope and timing in advance.
