Compare the stated scope, not broad supplier claims
Buyers evaluating China CNC finishing services should make each quote refer to the same part revision, material, quantity and required final condition. "CNC finishing" can refer to different post-machining steps, so name the requested finish or attach the customer specification instead of relying on a general label.
Check what is included
Ask whether preparation, masking, coating or treatment, inspection and packaging are included. Mark threads, fits, sealing surfaces and other areas that need protection. Confirm whether critical dimensions are checked before or after finishing and what evidence will be supplied. List the assumptions, exclusions and any proposed substitutions in writing.
Keep geography separate from technical acceptance
Supplier location does not define the finish requirement or prove a quality level. Review material compatibility, the drawing, required finish reference and acceptance method for the specific part. Do not compare a quote that includes treatment and inspection with one that prices machining only.
For general finish-scoping guidance, see les services de finition de surface CNC. For a coating-specific checklist, see services d'anodisation pour pièces usinées.

Jucheng provides machining and finishing for customer parts; it does not sell CNC equipment. Confirm project-specific feasibility and schedule after reviewing the complete request.
