Drawing-Based Manufacturing
We review dimensions, geometric controls, threads, surface roughness, cosmetic zones, and material notes before quotation. Questions are resolved before the production version is released.
What Is Included in Our CNC Machining Service
Our CNC machining service covers engineering review through finished-part delivery. We use the released CAD model and drawing to plan datums, workholding, tools, inspection points, and any outside finishing or assembly steps. This approach keeps prototypes, low-volume jobs, and repeat orders aligned to the same approved definition.
Prototype to Repeat Production
One-off prototypes, engineering samples, trial runs, small batches, and recurring orders can be planned around the quantity, risk, inspection, and revision requirements of each project.
Finishing and Assembly Support
Anodizing, etching, laser engraving, dyeing, baking paint, deburring, cleaning, and assembly coordination can be included when the drawing and acceptance standard define the requirement.
3-Axis, 4-Axis, and 5-Axis Process Planning
Axis selection is a feature of process planning, not a blanket capability claim for every part. Three-axis machining is often efficient for prismatic parts with accessible faces. Fourth-axis indexing can help with multiple radial faces or repeatable rotary positioning. Five-axis work can reduce setups for complex surfaces and improve tool access when the geometry and equipment justify it. Final selection depends on model geometry, datum strategy, part size, workholding, cutter reach, tolerance, and quantity.
| Planning factor | What we review |
|---|---|
| Part geometry | Pockets, bores, angled faces, compound surfaces, deep features, and access around the complete component |
| Workholding and datums | How the part is located, clamped, indexed, and referenced between operations |
| Production target | Setup time, quantity, repeatability, inspection sequence, and whether a dedicated fixture is justified |
Materials and Typical CNC Parts
Aluminum and Stainless Steel
Aluminum housings, plates, brackets, covers, and heat-dissipation components can be reviewed alongside stainless steel shafts, fixtures, sleeves, and structural parts. See aluminum CNC machining and stainless steel machining.
Brass and Engineering Plastics
Brass connectors, fittings, spacers, and conductive components, plus selected engineering plastic parts, are assessed by grade, machinability, dimensional stability, and application. See brass CNC machining.
Industry Applications
Common part contexts include automation equipment, electronics, photographic accessories, robots, audio equipment, and industrial machinery. Review our industrial machinery parts page for application-specific planning.
Tolerance, Inspection, and Quality Planning
Achievable tolerance is confirmed from the drawing rather than promised as one number for every component. Geometry, material condition, size, datums, workholding, thermal effects, finishing, and measurement method all matter. Critical fits, threads, bores, sealing faces, mounting patterns, and cosmetic surfaces should be identified in the released documentation.
Inspection Scope
Dimensional checks can be organized around critical features, first-article needs, sampling, in-process checks, and final reports. Visit Quality Control for the inspection workflow.
Revision Control
Include drawing revision, model revision, approved deviations, and inspection criteria so repeat orders use the same released definition.
Surface and Assembly Checks
State finish, masking, burr limits, cleaning, fastener torque, fit checks, and any assembly acceptance criteria before production.

CNC Machining Services FAQ
Do you support 3-axis, 4-axis, and 5-axis CNC machining?
Process planning can consider 3-axis, 4-axis, or 5-axis machining according to part geometry, tool access, datums, workholding, and the equipment available for the project. The suitable process is confirmed during drawing review.
What materials can you machine?
We review aluminum, stainless steel, brass, and selected engineering plastics. The drawing or RFQ should identify the exact grade, temper or condition, acceptable alternatives, and certificate requirements.
What should I include in a CNC machining RFQ?
Send a STEP or STP model, dimensioned PDF drawing, quantity, material, critical tolerances, surface finish, inspection scope, assembly or packaging needs, destination, and target delivery date.
