Mounting plates
Machine bases, motor plates, adapter plates and sensor mounting plates.
CNC Milling
Custom CNC Milling for Machinery and Automation Components
Milled plates, housings, brackets and fixtures with pockets, holes, threads, datums and assembly-critical features.
Part families
Where CNC milling is usually the practical route
Milling is well suited to prismatic parts that combine flat datum surfaces, pockets, slots, holes, threads and features on several faces.
Housings and covers
Aluminum, stainless-steel and plastic enclosures with internal features and threaded holes.
Brackets and supports
Structural, positioning and alignment brackets for equipment modules.
Jigs and fixtures
Assembly nests, inspection fixtures, datum blocks and positioning tooling.

Engineering review
Features we check before quoting a milled part
Thin walls and flatness
Thin sections may move during machining or after material removal. Flatness requirements should be tied to the actual assembly function.
Deep pockets
Depth-to-width ratio, cutter reach and chip evacuation affect tool selection, cycle time and surface quality.
Internal corner radii
Internal corners must match an available end-mill radius. Larger radii normally reduce machining effort and tool risk.
Hole and thread callouts
Thread standard, depth, class, insert requirement and access direction should be clear on the 2D drawing.
Datum strategy
Datums should reflect how the part is assembled and measured, especially when features are machined in multiple setups.
Cosmetic surfaces
Visible faces, tool-mark restrictions, edge breaks and finishing protection should be identified before production.
Capability profile
What can be evaluated
Machine strategy3-axis, 4-axis and 5-axis machining selected according to

What to mark on the drawing
- Critical holes, fits and flatness
- Thread standard and usable thread depth
- Datum references and inspection method
- Cosmetic faces and protected surfaces
- Finish thickness and post-finish dimensions
Common quotation gaps that slow a milling project
Only a 3D model
A model shows geometry, but a 2D drawing is still useful for tolerances, threads, finishes and inspection notes.
No repeat quantity
Knowing both the first batch and likely repeat demand helps evaluate workholding and process investment.
Unclear finishing
Color, gloss, masking, passivation and coating thickness can change cost and dimensional planning.
FAQ
Questions industrial buyers usually ask
Clear RFQ information reduces quotation assumptions and helps both sides compare the right manufacturing route.
Send a drawing for review →What types of parts are best suited to CNC milling?+
Plates, brackets, housings, fixtures and prismatic parts with pockets, holes, threads and features on several faces.
Why do internal corner radii matter?+
Internal corners are produced by round cutters. A practical radius improves tool access and reduces machining effort.
How are flatness and thin walls reviewed?+
The material removal pattern, workholding, wall thickness and actual assembly function are considered before a tolerance is accepted.
Should I send both 2D and 3D files?+
Yes. The 3D model defines geometry, while the 2D drawing carries tolerances, threads, datums, finish and inspection notes.
Have a Part Drawing to Review?
Send the drawing, material, quantity, finish and application. We will review the manufacturing route and confirm any missing information before quotation.
