CNC Machining Resources
Short, practical guides for the people who actually send drawings: what to include, how tolerances are read, which materials behave how, and what drives lead time. Written from the shop floor in Dongguan, not from a keyword list.
Guides
Start with the quoting guide — it removes most of the back-and-forth before a price is even discussed.
What Files Do I Need for a CNC Quote?
The minimum a shop needs to price a part, which formats are accepted, and the six details that most often stall a quote.
CNC Turning vs CNC Milling: What's the Difference?
How the two processes differ in geometry, cost and lead time, when to choose each, and when a turn-mill part is the cheaper answer.
What a CNC Machining Quotation Includes
The six lines a usable quote is built from, why the unit price is not the total, and how to compare two quotes on the same scope.
CNC Machining Tolerances: What ±0.005 mm Really Means
What a five-micron window costs, how to place tight callouts only where they matter, and how each tolerance band is measured.
What Materials Can Be CNC Machined?
Which metals and plastics can be CNC machined, how each behaves on the machine, and how to specify a material so that the part can actually be made and inspected.
Surface Finishing Options for Machined Parts
How anodising, plating, passivation and blasting change a machined part — what each adds dimensionally, what it costs, and how to specify it so the tolerance still holds.
CNC Milling Metal Parts: Material Selection Guide
A machinability comparison table for milled metal parts — aluminium, stainless, brass, copper and titanium — with relative cost and the decisions behind each grade.
