An Introduction to CNC Mills

Posted On: January 15, 2020

Computer Numeric Control (CNC) has become an integral part of new machining technologies. Perhaps one common type of machine used in this realm is CNC milling or CNC machining. CNC milling is similar to other machining processes such as drilling and cutting. All these processes are performed using a cylindrical cutting tool that can move along the axes to make the cuts. They are ideal for short-run production of difficult parts or manufacturing of precision components and parts. With the affordability of CNC machining, it’s undoubtedly wise to use CNC mills that can transform production processes. Owing to the immense popularity of CNC machining, these days, one can easily find various machining shops offering CNC milling services that meet your stringent requirement. Before employing these machining services, one should know the details about CNC mills such as how CNC mills work? Are CNC mills adjustable and versatile? What benefits does this machinery offer? 

How Do CNC Mills Work?

The CNC milling process uses computerized control to operate machine tools that can perform various manufacturing processes including cutting or drilling. A milling cutter can make a wide array of slots, shapes, holes and other necessary impressions while moving along multiple axes. In addition, the process follows the similar production stages that other CNC machining processes do. Here are some steps in the process:

• The milling process begins with the designing of the CAD model. Afterward, the completed design is transferred to a CNC compatible file format, which describes the machine actions as well as the tooling movements across the workpiece.
• Before the operator executes the CNC program, they set up the CNC milling machine by fixing the workpiece to the surface of the machine and assigning the desired machine tool head to the spindle.
• Depending upon the specifications of the milling operations, this process employs CNC milling machines that are vertical or horizontal, CNC-enabled milling machines and rotating multi-axes cutting tools.
• Once done with these stages, the operator launches the computer controlled program to execute the milling operation.

Are CNC mills Flexible and Adjustable?

‘Computer-controlled’ is one of the important features of CNC mills. The computer program feeds them the code taken from computer-aided manufacturing (CAM) software. This software is responsible for controlling the cutting tool paths needed to achieve the desired results.

CNC milling machines utilize a variety of tool heads including cutters, rounding mills, fluted mills, rotating tool, and ball-end mills. As its name suggests, the rotating tool ends can change there as per the task, and the computer communicates with the milling process to request tooling changes. Selection of tool heads entirely depends on the desired outcome and materials.

Why Use CNC mills?

CNC milling has an edge over conventional machining techniques. CNC machining is known for delivering superior results in a way that’s both efficient and more effective. Apart from being able to develop complex parts, CNC machining offers various benefits. The following are some of them:

1. Cost Efficiency: Using computerized control, CNC mills progressively remove material from the workpiece. This minimizes waste through increased precision.

2. Speed: CNC mills quickly produce the parts or components that would normally require various manufacturing steps.

3. Safety: Automated fabrication process minimizes risks and operators can avoid harm.

4. Efficiency: CNC mills consist of internal quality detectors. It helps to prevent the wastage of material if any deficiency is found.

Outlined above are the basics of CNC mills. Owing to their beneficial features, they are absolutely essential for the manufacturing processes today.
