Topic cluster: Case Study
Automation equipment often uses aluminum CNC machined parts such as brackets, plates, mounting blocks, covers, fixtures, and prototype components.
Buyer problem
The buyer needs parts that assemble correctly with motors, sensors, rails, fasteners, and machine frames. Hole position, flatness, and surface finish can be more important than the overall shape.
Engineering explanation
Aluminum parts are commonly produced by CNC milling, drilling, tapping, pocket machining, and deburring. Fixture planning is important for flatness, hole alignment, and repeatability.
Key factors for quotation
- Material: aluminum 6061 / 6063 / 7075 depending on application
- Process: CNC milling, drilling, tapping, pocket machining
- Critical features: hole position, flatness, threaded holes, mounting faces
- Inspection: hole spacing, thread check, surface check
- Finish: as-machined, anodizing, or other finish after review
Common mistakes
- Not marking critical mounting holes
- Ignoring wall thickness around pockets
- Requesting cosmetic finish without explaining visible surfaces
What buyers should prepare before RFQ
For drawing-based CNC machining, the most useful RFQ package includes a 2D drawing for tolerances and notes, a 3D model for geometry review, material grade, quantity, surface finish, and the application or assembly function of the part. If the part connects with another component, include thread standard, mating dimensions, bearing seat information, or sample photos when available.
Buyers do not need to solve every manufacturing detail before sending an RFQ. The important point is to make the engineering intent clear: which features must fit, which surfaces are cosmetic, which dimensions are critical, and whether the order is for prototype testing, small batch production, or repeat OEM supply.
How we support RFQ review
For aluminum automation parts, send STEP model, PDF drawing, material grade, surface finish, quantity, and assembly notes.
After receiving a complete RFQ, we review the drawing for manufacturability, compare the process route with the required tolerance, and check whether inspection needs are practical for the requested quantity. This helps reduce unclear quotation assumptions and gives buyers a more useful basis for comparing suppliers.
