What is CNC Milling?

CNC milling is a method of using computer-controlled milling machines to cut metal or plastic. It includes 3-axis, 4-axis, and 5-axis milling. 3-axis milling moves the tool in three directions, with an additional rotation axis on the 4-axis and two rotation axes on the 5-axis, allowing the tool to cut workpieces more flexibly and handle more complex geometric shapes and surfaces.

About CNC Milling FAQs

Yes, we can provide sample or prototype production services according to your requirements. Whether you need low-volume manufacturing or a single sample, we can meet your needs.

The choice of axis depends on the complexity of your project. Typically, for simple flat and simple curved surfaces, 3-axis milling is sufficient. If more axis movements are required to handle complex geometries and surfaces, 4-axis or 5-axis milling would be more suitable.

By utilizing the latest CNC milling capabilities, Boyi can produce high-precision and fast milling parts within 48 hours. We strive to ensure high efficiency and timely delivery.
