CNC Milling Service

CNC milling belongs to the machining process, it can be used to create complex 3D shapes or to apply a machined feature or surface to parts for both plastics and metals. The machinery is the most important element for the process of milling, Premium precision machine inc uses multi-axis milling machines includes the 3&4&5 axis that creates many different parts types and features of complex geometries. That means can be slots, angled shapes, holes, curves, circulars, and channels.

How Does CNC Milling Work?

CNC milling is a certain type of CNC machining services, a machining process suitable for high accuracy and high tolerance parts in prototype and small to medium production runs. Some milling machines can achieve tolerances of up to and greater than +/- 0.005mm. The versatility of the milling process allows it to be used in a wide range of industries and for a variety of part features and designs, including slots, chamfers, threads, and pockets. The most common CNC milling operations include Face milling, Angular milling, Form milling, Plain milling.

CNC milling is often grouped by the number of axis, from 3 to 5 axis. Each axis is labeled using a specific letter. For instance, X and Y axis stands for the horizontal movement of the mill's workpiece. The Z-axis designates vertical movement and the W axis represents the diagonal movement across the vertical plane.
