RAC Precision provides custom CNC machining services for precision metal and plastic components, including CNC milling, CNC turning, drilling, tapping, boring, and other secondary machining processes.
We specialize in small to medium-sized precision machined parts for industries such as industrial automation, motion control, optics, optoelectronics, sensors, laser systems, and specialized equipment.
We also provide sheet metal fabrication and coordinate surface finishing, plating, anodizing, and coating services to offer a complete manufacturing solution.
RAC Precision is a Taiwan-based CNC machining supplier serving customers in North America, Europe, the UK, and other international markets.
Our manufacturing operations are located in Taiwan, allowing us to provide competitive CNC machining costs while maintaining close engineering communication and quality control.
We work with international customers on prototypes, low-volume production, and recurring production orders.
We machine a wide range of engineering materials, including:
Common aluminum and stainless steel grades can be machined according to customer drawings and specifications.
If you require a special material or material certification, please provide the material specification when requesting a quotation so we can confirm availability and sourcing requirements.
The achievable tolerance depends on the material, part geometry, feature size, machining process, and required inspection method.
For general CNC machining, tolerances are typically specified according to the customer's engineering drawing or applicable standards.
For critical dimensions, tight tolerances and GD&T requirements, our engineering team reviews the drawing before quotation to determine the appropriate machining process and inspection method.
For precision requirements, please clearly identify critical dimensions and GD&T callouts on your drawing.
For the most accurate quotation, we recommend providing:
A 3D model helps us understand the part geometry, while the 2D drawing defines critical dimensions, tolerances, GD&T, threads, surface finish, and other manufacturing requirements.
If you only have a 2D drawing, you can still contact us and we will review your requirements.
To request a quotation, please send us your 2D drawings and 3D CAD files together with the required quantity.
For the most accurate quotation, please also provide:
Our engineering and sales team will review the requirements and provide a quotation based on the manufacturing process, material, quantity, finishing, and quality requirements.
There is no fixed minimum order quantity for every CNC machining project.
We can evaluate:
The most economical quantity depends on the part geometry, material, tooling, setup requirements, and finishing process.
Please contact us with your drawings and required quantity so we can recommend the most suitable production method.
Yes. We support both low-volume and recurring production orders.
Our CNC machining service is suitable for customers who need anything from prototype quantities to repeat production batches.
For production orders, we can review the annual demand, batch quantity, delivery schedule, material requirements, and quality documentation to develop an appropriate manufacturing plan.
RAC Precision follows a quality control process covering material verification, in-process inspection, final inspection, and dimensional verification.
Depending on customer requirements, we can provide inspection reports and quality documentation for production parts.
Critical dimensions can be identified and inspected according to the customer's engineering drawing and quality requirements.
Yes. Certificate of Conformance / Certificate of Conformity can be provided when required by the customer.
Additional quality documentation may include material certificates, inspection reports, dimensional reports, RoHS documentation, and other project-specific documents.
