Drawing-Based Manufacturing

Custom CNC Machining China

Hasun reviews custom milled and turned parts from the drawing outward: geometry, material, finish, inspection points, quantity, and assembly use. This gives buyers a practical basis for comparing process fit instead of comparing an unsupported unit price.

Drawing review

Datums, critical dimensions, threads, mating faces, and cosmetic areas are checked before the manufacturing route is discussed.

Process planning

Milling, turning, drilling, tapping, deburring, and finishing are selected around the part geometry and required quantity.

Buyer confirmation

Material grade, finish, inspection expectations, packaging, and delivery destination should be confirmed in the RFQ.

RFQ Review Checklist

Part definition3D model, controlled 2D drawing, revision, material grade, surface finish, and quantity.
Critical requirementsDatums, tolerances, threads, mating faces, cosmetic surfaces, and inspection expectations.
Commercial contextPrototype or batch stage, delivery destination, packaging, assembly use, and preferred contact method.

Buyer Questions

What files should I send?

A STEP or IGES model plus a 2D drawing is preferred when tolerances, threads, or inspection dimensions matter.

Can a supplier quote from a sample?

A sample or clear photos can start the review, but measurable dimensions and material requirements are still needed before production.
