Best Design Practices For CNC Machining
Avoid Deep Narrow Cavities
Avoid deep cavities with small diameters; they cause tool deflection, poor surface finish, excessive vibration, and longer machining time. Use stepped depths instead.
Keep Wall Thickness Consistent
Maintain consistent wall thickness; uneven walls lead to vibration, distortion, and poor dimensional accuracy during high-speed milling or turning operations.
Match Fillets to Cutter Radii
Design internal fillets that match standard cutter radii; mismatched corners require custom tools or multiple passes, increasing machining cost and cycle time.
Specify Practical Tolerances
Only specify tight tolerances where absolutely necessary. Over-dimensioning increases inspection time and manufacturing costs significantly.

Frequently Asked Questions
After you upload your CAD or drawing, senior machinists check key items like geometry, tolerances, wall thickness, tool access, radii, threads, and material behavior.
Our lead time is determined by part geometry, tolerance requirements, finishing needs, and order quantity. Most CNC-machined prototypes ship within 3–7 working days, while more complex components or multi-process assemblies may require additional time.
Yes. XTJ offers a full range of documentation to support both standard and high-precision projects. Upon request, we provide material mill certificates, RoHS/REACH compliance, and traceability reports for all metals and engineering plastics we source.
CNC machining pricing is primarily driven by machining time, which depends on part geometry, tolerances, and material machinability. Additional factors such as fixture design, tool paths, surface finishing, and inspection requirements also influence the final cost.
At XTJ, every part receives strict dimensional checks, material verification, and final QC approval. Critical features are inspected 100%, and reports can be provided for confirmation, minimizing the chance of nonconforming parts leaving our facility.
