CNC milling is one of the most common industrial metal-working processes, offering versatile and precise machining compared to other methods. While laser and plasma are often hailed as the peak of cutting-edge technology, a CNC mill gives more than what those can achieve.
For businesses looking for efficient steel engraving methods, CNC milling is the key. CNC machines use various techniques, beginning with a 3d model or a computer-aided design (CAD) of the product. The following discusses the five main techniques CNC milling machines use for engineering precision:
- Plain or Surface Milling
CNC milling involves using computer-assisted rotary cutting tools to remove material from the surface of a work item. In plain or surface milling, the rotation axis of the mill moves parallel to the workpiece.
The outcome will vary depending on the tool used. Wide cutters will remove material quickly, but the finish won’t be as good. If you want the best results, fine-tooth cutters can leave a great finish at fast cutting speeds and slow feed rates.
- Optical Grinding
If you need help with specialty optics, CNC milling machines are of great help. Optics demand close tolerances and thin surfaces, which can be difficult with most other industrial processing methods.
CNC milling uses grinding equipment that spins and grinds against the surface, eliminating nominal deviations. A grinding paste is often used for lubrication and to polish the finish of the work item’s surface.
- Angular Milling
In angular milling, the CNC machine’s tool faces the material at an angle. This technique is leveraged for applications with angular cuts – including grooves and dovetails – making the procedure more precise and faster.
If the item in question requires simultaneous movement of X, Y, and Z axes, engineers recommended employing a 3-axis mill. Putting different cutters, such as conical cutting heads and dovetail cutters, will help you attain different angular cuts.
- Form Milling
Do you need a specific accuracy for every detail in your component? Do you want radii, curves, and counters on the workpiece but can’t achieve it using lasers? Form milling is the solution to these questions.
Form milling uses different kinds of tools for every detail included in the design, saving you time switching between heads. When done correctly, you can achieve non-flat cuts in a single session.
- Profile Milling
Profile milling utilises round inserts and ball-nose end mills to create concave and convex designs. This technique follows three steps: rouging, half-finishing, and final finishing.
