CNC Machining

CNC Turning Parts

Rotational and cylindrical components — shafts, sleeves, bushings, and threaded parts — coordinated from manufacturing resources in China, with specifications and delivery confirmed per inquiry.

What Is CNC Turning?

CNC turning is a machining process in which the workpiece rotates against a stationary cutting tool on a lathe. It is the standard process for rotational geometries: stepped diameters, grooves, threads, bores, and tapered features produced in a single setup.

Jinjiuhui coordinates CNC turned parts through manufacturing resources in China. We are a trading and sourcing coordination company, not a factory — achievable tolerances, surface finishes, and size ranges depend on the part and the assigned resource, and are confirmed per inquiry.

Frequently Asked Questions

What information do you need to quote a turned part?
Part name, material, quantity, outer diameter, length, thread specifications, destination country, and required delivery date. Drawings can be shared by email after the initial inquiry.
Do you publish machining tolerances for turned parts?
No. Tolerances depend on the part geometry, material, and the assigned manufacturing resource. They are confirmed per inquiry instead of published as generic figures.
Can I order small quantities or prototypes?
Small-batch and prototype quantities can be evaluated. There is no fixed site-wide MOQ — MOQ, price, and lead time are confirmed per order.
Which material grades are available for turning?
Aluminum, stainless steel, carbon steel, copper, and engineering plastics can be inquired about. Specific grades are confirmed with the supply team per requirement.
Can you provide material certificates with the order?
Where the supplying factory can provide material certificates or inspection reports, we coordinate them with your order. Available document types are confirmed before production.
