CNC Turning ±0.025 ±0.01 Finish can impact tolerance.
CNC Milling ±0.025 ±0.005 Precision can vary based on tool type andmaterial.

Why Choose Us

  • Precision machining is necessary when your project requires components with extremely tight tolerances, intricate designs, or complex geometries that standard machining cannot achieve. This method is essential in industries where precision is critical, such as aerospace, medical devices, and electronics. If your parts need to perform under high stress, withstand extreme conditions, or fit into precise assemblies, choosing precision machining ensures the reliability and functionality of your products.
  • Yes, precision machining is specifically designed to provide tight tolerances. This technique can achieve tolerances as narrow as +/- 0.0005 inches, which is essential for creating highly accurate and consistent parts. The ability to maintain such precise measurements is crucial in applications where even the smallest deviation can lead to significant issues, such as in aerospace components or medical devices. Advanced CNC machines, which are commonly used in precision machining, are capable of producing parts with these strict specifications reliably.
  • To get a quote for a CNC precision machining project, you should prepare detailed information about your part or assembly, including CAD drawings, material specifications, and quantity needed. You will also need to specify the tolerances required and any additional post-processing like finishing or heat treating. With this information, go to RapidDirect online platform where you can upload your design files and receive a pricing estimate quickly.
