What Is CNC Milling

At ProtoTech Machining, CNC milling is the precision process of cutting solid plastic or metal materials into final parts using advanced 3-, 4-, and 5-axis milling machines. Unlike CNC lathes, our CNC mills remove material by rotating and moving a cutting tool, such as a milling cutter, while positioning the workpiece accurately to achieve a finished or semi-finished shape. Our multi-axis milling machines enable a versatile, accurate, and repeatable CNC milling process, facilitating the production of various features and complex geometries. Examples include channels, holes, curves, and corners. Additionally, milling serves as an ideal method for crafting tooling used in die casting and injection molding. ProtoTech Machining boasts state-of-the-art facilities housing imported 3-axis, 4-axis, and 5-axis CNC mills equipped with diverse tool sets, maximizing production efficiency and speed.

Why Choose CNC Milling

CNC milling is an ideal choice for manufacturing angled shapes, planes, grooves and channels, holes, curves, chamfers, and many other features.
Milling is not only used to manufacture finished parts, but also used to build molds for plastic injection molding and pressure die casting.
CNC milling machines can remove a large number of materials quickly and accurately, and produce good surface finishes at the same time.
CNC milling can machine different parts with a variety of materials. This process can be carried out on any rigid material.
Milling is the most versatile of all available CNC machining processes.
Because no other specialty tools need to be manufactured and no requirements for minimum order quantity, the process is highly cost-effective compared with additive manufacturing.
Minimal setup time makes it possible that CAD files can be converted to finished products in a few hours.
