CNC Milling Standards & Tolerances

As a professional CNC milling service provider JST, we pride ourselves on our advanced machining equipment and rigorous machining processes to ensure the highest level of precision and error control. The CNC milling machines we use are equipped with high-precision CNC systems that allow for extremely small machining errors. Our machining equipment has excellent performance parameters, such as:

Positioning accuracy: Our CNC milling machines have extremely high positioning accuracy, typically in the micron range. This means that we can accurately position the cutting tool to the specified location on the workpiece, ensuring that each machining step achieves the required accuracy.

Repeatable Positioning Accuracy: Our CNCs have excellent repeatable positioning accuracy, typically below a few tens of microns. This means that over the course of multiple machining operations, we can ensure that the repositioning accuracy of the workpiece is very high, thus maintaining the consistency and stability of the part.
Surface Quality: Our CNC milling machines are equipped with high speed spindles and high quality cutting tools that allow for high speed cutting and smooth cutting surfaces. This ensures that our machined parts have excellent surface quality and reduces the need for subsequent machining and processing.

Combining the performance parameters of these machining machines with our strict numerical control of machining, such as cutting speed, feed rate, depth of cut, etc., we can ensure that our machining accuracy meets our customers' requirements. Whether we are machining complex shaped parts or parts that require extremely high dimensional accuracy, we are able to provide high quality, high precision customized machining services.
