Details of Your Parts: Tolerances, Materials, & Finishes

Standard Tolerance CNC Machined Parts

Every part is manufactured with rigorous attention to detail. For those with specific needs, we welcome 2D drawings to guide our production. In the absence of these, indicating tolerances with ISO 2768 standards ensures that we still meet your precise requirements. See the standard we follow and how we make sure the parts meet the requirements.

Optional Materials

Aluminum, stainless steel, brass, titanium, copper, ABS, POM, PEEK, and wood material, we pride ourselves on offering an extensive array of industrial-grade CNC machining materials with certification. This diversity ensures that you can select the perfect material to meet the specific requirements of your custom parts, whether for prototyping phases or full-scale production runs.


Surface Finishes

BaiChuan Precision elevates the standard for CNC machined parts with a comprehensive suite of high-quality surface finishes such as polish, bead blasted, anodized(Type II & Type III), brush, galvanization, powder coat, passivation, electroless nickel plating, and PVD. Our offerings are designed to enhance the aesthetic appeal, durability, and performance of your components, ensuring they meet both functional requirements and visual expectations.

From Prototyping to Production

We offer comprehensive custom CNC services tailored to meet the needs of any production volume – from prototyping to high-volume manufacturing of 10,000+ units. Our expertise ensures your transition from initial idea to end-use production parts is seamless and efficient.


Prototype Machining: Perfecting Your Design

Prototyping allows detailed evaluation of appearance, function, and material properties. This crucial step ensures your design is not just viable but optimized for production. We’re committed to quality, precision, and rapid turnaround, streamlining your journey from concept to final product.
