Custom CNC Machining Services
Drawing-based CNC machining for precision metal, plastic, ceramic, and composite parts—from prototypes and low-volume builds to repeat production.
CNC Machining Capabilities
Core ranges for initial project review. Final capability is confirmed against geometry, material, workholding, tolerance, and inspection requirements.
Unless tighter critical features are identified and reviewed.
Subject to geometry, process route, material, and agreed inspection.
Practical minimums vary with part size, material, and feature depth.
Usable part size depends on fixturing, travel, access, and machine choice.
Maximum diameter and length are confirmed from the full geometry.
Finer surfaces are evaluated with grinding or secondary finishing.
*Quoted limits are not universal guarantees; critical dimensions are confirmed after drawing and process review.

PTFE
Low friction and broad chemical resistance for seals, insulators, liners, and sliding components.
FR4 / G10
Electrical insulation and structural stability for fixtures, plates, and electronic equipment components.
PE / UHMW-PE
Impact, wear, and low-friction performance for guides, wear strips, and handling equipment.
Specify the exact grade, temper or supplied condition, certification needs, and any restricted substances in the drawing package.
Surface Finishing Options
Finishes are selected for appearance, corrosion resistance, wear, conductivity, cleanability, or identification.
Machined Finish
Visible tool marks with burr removal and drawing-defined edge treatment.
Anodizing
Decorative or hard anodizing for compatible aluminum alloys and applications.
Sandblasting
Uniform matte texture for appearance or preparation before another finish.
Powder Coating
Durable colored coating for suitable parts with masked functional surfaces.
From Drawing Review to Final Release
A controlled route connects engineering review, machining, inspection, cleaning, and protective packaging.
Confirm requirements
Material, datums, tolerances, finish, quantity, and inspection scope.
Plan the route
Programming, tooling, workholding, sequencing, and in-process checks.
Verify critical features
Inspection uses suitable calibrated equipment and agreed methods.
Clean and protect
Parts are cleaned, identified, protected, and packed for shipment.
Inspection Matched to Part Risk
Inspection planning follows the drawing, critical-to-function features, process capability, and the level of documentation agreed for the order.

CNC Machining Questions
How does CNC machining produce a part?
A programmed machine removes material with controlled cutting tools. The process route, workholding, tools, and inspection method are selected from the drawing and material.
What information is needed for an accurate quote?
Provide a 3D model and controlled drawing, material grade, quantity, critical tolerances, finish, inspection records, and delivery target.
What affects CNC machining cost and lead time?
Material, stock form, geometry, setups, tight tolerances, surface finish, inspection, secondary processing, quantity, and material availability all affect the quote.
How should a part be prepared for DFM review?
Identify functional datums and critical features, use practical tolerances, allow tool access, and distinguish cosmetic surfaces from standard machined areas.
When is CNC machining preferred over 3D printing?
CNC machining is typically selected for production-grade stock materials, tighter tolerances, stronger directional properties, and controlled machined surfaces.
