CNC Support to Make Your Cast Parts Ready for Assembly

Yongzhu Casting provides CNC machining support for custom cast parts, especially aluminum die cast components that need tighter dimensions, threaded holes, mounting surfaces, sealing faces, or finished assembly areas.

  • Machining support after casting
  • Drilling, tapping, milling and turning
  • Machined holes, threads, slots and flat surfaces
  • Casting, machining, finishing and inspection support based on drawings

What We Machine After Casting

Not every surface of a cast part needs CNC machining. We focus on the areas that affect assembly, function, sealing, installation and inspection. Common machining areas include:

  • Threaded holes
  • Mounting surfaces
  • Sealing faces
  • Locating holes
  • Flat surfaces
  • Bearing seats
  • Slots and grooves
  • Tight-tolerance dimensions

What You Can Get From Our Machining Support

Yongzhu Casting supports machined cast parts based on your drawings, samples and project requirements.

Have a Cast Part That Needs Machining?

Send your drawing and tell us which areas need machining, drilling, tapping or finishing. We can check whether the part should be cast directly, machined after casting, or adjusted before production.

Questions Before Sending Your Drawing

Do you provide CNC machining as a standalone service?

Our CNC machining is mainly provided for custom casting projects that require secondary machining after casting.

Common areas include threaded holes, mounting surfaces, sealing faces, locating holes, flat surfaces, bearing seats and tight-tolerance dimensions.

Yes. If the drawing shows machining requirements, we can quote the casting part together with CNC machining, tapping, drilling or surface finishing.

Tolerance depends on the part structure, material, machining area and drawing requirements. Please send the drawing for review before quotation.

Usually CNC machining is arranged before final finishing, but the process should be confirmed based on the drawing and surface requirement.

Please send a 2D drawing or 3D file, material requirement, quantity, tolerance, machining areas and surface finish requirement.

Send Your Drawing for Casting and Machining Review

If your cast part requires CNC machining, drilling, tapping or finishing, send us your drawing or sample photos. Yongzhu Casting can review the casting requirement and machining areas together, then provide a quotation based on your project.
