FAQs

Custom Robot CNC Parts FAQs

What tolerances can you achieve for robot CNC parts?
For critical high-precision components, we can achieve tight tolerances down to +/- 0.005mm. While final achievable tolerance depends on the specific material and part geometry, our advanced CNC equipment routinely ensures the strict accuracy required for bearing fits, joint assemblies, and transmission systems.
What materials and surface treatments do you offer for robot CNC parts?
We machine a wide range of metals and engineering plastics, including aluminum, stainless steel, steel, titanium, PEEK, and Delrin. Multiple surface treatments are available, such as anodizing, plating, passivation, and powder coating, based on application requirements.
Can you provide inspection reports or quality documentation?
Yes. We provide comprehensive quality documentation to support your engineering verification. This includes First Article Inspection (FAI) reports for initial validation, as well as standard dimensional inspection reports and material certifications for full production batches, ensuring every part meets your exact specifications.
How do you ensure part quality and dimensional accuracy?
We follow strict machining and inspection procedures, including in-process checks and final dimensional inspection. All robotic CNC parts are manufactured according to customer drawings, tolerances, and specifications to ensure consistent and repeatable quality.
Can you sign a Non-Disclosure Agreement for our robot project?
Yes. We fully support customer confidentiality and can sign NDA agreements before reviewing drawings or project details. All technical documents and data are handled under strict internal confidentiality controls.
Do you support both prototypes and production volumes?
Yes. We support CNC machining for robotic parts from prototype development to low and medium-volume production, ensuring consistent quality, material control, and process repeatability across all stages.
What is your typical lead time for robot CNC parts?
Lead time depends on part complexity, material, and quantity. For most robotic CNC parts, prototypes are typically completed within 7–10 working days, while production batches are delivered based on order volume and process requirements.
How do you ensure strict compliance with customer drawings?
All robot CNC parts are machined strictly according to customer-provided drawings and specifications. Any deviation, optimization suggestion, or technical clarification is communicated and confirmed before production begins.
