FAQ

Q1. What are custom precision milling parts?

Custom precision milling parts are non-standard components manufactured from a drawing, CAD model or approved sample. They can include small housings, inserts, brackets, flanges, plates, clamps, threaded bodies and multi-face metal parts.

Q2. When is 5 axis CNC machining useful?

5 axis CNC machining is useful when a component has angled faces, compound surfaces, features on multiple sides or limited access for standard setups. The actual machine route should be confirmed after reviewing the geometry.

Q3. Can you produce small aluminum CNC machined parts?

Small aluminum CNC machined parts can be reviewed according to the drawing, material grade, wall thickness, feature size, tolerance and quantity. The final feasibility depends on the part design and selected process.

Q4. Can you machine stainless steel as well as aluminum?

Yes. Aluminum and stainless steel are both within the stated material direction. Exact grades, heat condition, finish and inspection requirements should be listed on the drawing or purchase specification.

Q5. Do you support both milling and turning?

Yes. Milling is suitable for faces, pockets, slots, holes and irregular profiles. Turning is suitable for coaxial shafts, sleeves, rings and threaded cylindrical bodies. A combined route can be considered for parts with both feature groups.

Q6. Can the parts be made from one sample?

A sample can support a project review, especially for replacement or reverse-engineering work. For accurate repeat production, a 2D drawing or 3D CAD file with material and tolerance information is preferred.

Send your drawing, CAD model or approved sample to discuss 5 axis CNC machining, custom precision milling parts and small aluminum CNC machined parts for prototypes, industrial equipment, automation, fixtures and replacement programs.
