CNC Turning vs CNC Milling: What Is the Difference?
CNC turning rotates the workpiece against a fixed cutting tool, while CNC milling rotates the cutting tool against a fixed workpiece. This article explains how each process works, which part geometries suit each one, and what buyers should confirm before placing an order.
Read article →Information Needed to Source CNC Machined Parts from China
To quote CNC machined parts from China, suppliers need your drawing or key dimensions, material, quantity, destination country, and required delivery date. This article lists the complete information set and explains which details speed up a quotation.
Read article →Material Parameters to Confirm Before Requesting a CNC Quote
Before requesting a CNC machining quotation, confirm the material grade, applicable standard, supply form, and any hardness or heat-treatment condition. This article explains which material parameters matter and which ones are verified per order.
Read article →How to Evaluate Small-Batch CNC Machining Orders
Small-batch CNC orders should be evaluated on cost structure, process feasibility, and lead time rather than unit price alone. This article explains where small-batch costs come from and what buyers should confirm before committing.
Read article →Sourcing Machined Parts from China to Vietnam: Key Checks
When shipping custom machined parts from China to Vietnam, buyers should confirm export documents, import requirements with their customs broker, freight method, and pre-shipment quality checks. This article covers the items to verify per order.
Read article →How to Check Dimensions and Quality of CNC Machined Parts
Checking CNC machined parts starts with clear requirements: tolerances on the drawing, agreed inspection methods, and defined quality documents. This article explains what to specify, what to verify, and how pre-shipment checks work.
Read article →Aluminum vs Steel vs Copper vs Plastics: How to Choose
Material choice for machined parts is driven by function, environment, and cost: aluminum for light weight, stainless steel for corrosion resistance, carbon steel for strength at low cost, copper for conductivity, and engineering plastics for insulation and low friction. This article compares the five groups.
