What Is CNC Milling?
CNC milling employs rotating cutting tools to remove material from a workpiece, creating finished parts and products. This versatile manufacturing process is suitable for a wide range of materials, including metals, polymers, wood, and glass. Standard CNC milling systems typically operate with three linear axes (X, Y, and Z), ensuring exceptional precision and detail.
HRC Metal also provides advanced 5-axis systems, where the tool head and machining bed (A and B axes) can rotate, enabling the production of highly complex geometries in a single setup. This eliminates the need for multiple machine configurations, streamlining the process for intricate parts.

CNC Milling Services for Metal and Plastic Components
CNC Metal Milling Parts
Metal materials are widely used in CNC milling for their durability and strength. Common metals widely used in the milling process include aluminum, stainless steel, and brass. Other materials that can be used for milling are copper, bronze, magnesium, titanium, zinc, etc.
CNC Plastics Milling Parts
Plastic materials are often used in CNC milling because they are easy to machine and have a wide range of properties that make them ideal for many applications. It includes ABS, acrylic, PC, PVC, Nylon, POM, PE, Teflon, etc.
How Does CNC Milling Work?
Milling is a subtractive manufacturing process where the cutting tool moves into the clamped material at high speed and with a specified feed rate. Unlike turning, the tool rotates while the workpiece remains stationary.
Modern CNC milling machines gradually remove material from blocks, plates, or bars using various cutting tools, known as milling heads, until the workpiece achieves the desired shape. The shapes and tolerances are defined by a custom NC program, which the CNC machine executes with precision. At HRC Metal, we typically use 3-axis or 5-axis milling machines to process semi-finished products.
Our advanced manufacturing expertise not only reduces machining and setup times but also enhances the precision of CNC milling. Most importantly, it significantly improves throughput times, especially when producing large quantities, ensuring efficiency and high-quality results.
CNC Milling FAQs
What is a CNC milling center?
A CNC milling center, also known as a CNC machining center, is a computer-controlled machine tool used for the precision machining of complex parts. It combines the capabilities of a milling machine with automated control, allowing for high accuracy, repeatability, and efficiency in manufacturing processes.
What are the benefits of CNC milling?
CNC milling offers a combination of precision, efficiency, versatility, and cost-effectiveness, making it an essential process in modern manufacturing. Its ability to produce high-quality, complex parts with minimal waste and labor makes it a valuable tool for industries requiring reliable and scalable production solutions.
How does CNC milling work?
Unlike additive manufacturing, CNC milling is a type of machining that uses computer numerical control (CNC) technology to remove excess material from a workpiece. It begins with a CAD file. This file is used to create a toolpath, which is a set of instructions that tells the CNC lathes how to move the cutting tools across the workpiece.
What finishing options are used in CNC milling?
The finish on CNC milled parts can provide a protective and decorative surface that is both wear and corrosion-resistant and aesthetically pleasing. There are a number of finishing options available for CNC mills, and the best option will depend on the specific project requirements. Some common surface finishes include Polishing, Anodizing, Powder Coating, Plating like electroless nickel plating, Sandblasting and etc.
What is the difference between CNC turning and CNC milling?
The CNC milling process involves a rotating tool that carves away excess material from a stationary workpiece. CNC turning uses a rotating workpiece, typically used to make cylindrical parts.
