Additional CNC Machining Buyer Guides
These guides help buyers prepare clearer drawings, tolerance notes, inspection requirements, and RFQ information before requesting a quote.
What Information Is Needed for a CNC Machining Quote?
A useful CNC machining RFQ should include drawing files, material grade, quantity, tolerance notes, surface finish, inspection requirements, and application information. The more complete the RFQ, the fewer assumptions are needed before price review.
How Much Does CNC Turning Cost?
CNC turning cost depends on material, diameter, length, setup time, machining time, tolerance, threads, grooves, surface finish, inspection, quantity, and packing requirements. A drawing review is required before a reliable price can be confirmed.
Stainless Steel Shaft Machining: Process and Tolerance Guide
Stainless steel shaft machining requires review of material grade, length-to-diameter ratio, critical diameters, straightness, thread details, holes, surface finish, deburring, inspection, and packing before quotation.
CNC Turning vs CNC Milling: Which Process Fits Your Part?
CNC turning is usually used for round parts such as shafts, sleeves, pins, and connectors. CNC milling is usually used for flats, holes, slots, pockets, plates, and brackets. Some parts need both processes.
Common RFQ Mistakes for Custom CNC Parts
Common CNC RFQ mistakes include missing drawings, unclear material, no quantity, undefined tolerance, missing thread details, unclear surface finish, no inspection scope, and no packing requirements for sensitive parts.
