CNC Milling FAQs
1. What parts can be processed by CNC milling?
Modern CNC milling machines can be configured as horizontal or vertical machining centers and produce different components using plastics, ceramics, composites and metals. Automatic tool changers, tool carousels and magazines, cooling systems and housings are among the technical elements.
2. What is the difference between CNC turning and CNC milling?
Turning operations are performed by rotating the workpiece and using a fixed cutting tool while milling operations are performed by rotating the cutting tool and locking the workpiece in place.
3. What types of materials do CNC mills use?
The most common materials used in CNC milling are metals such as brass, titanium, aluminum or steel, and plastics such as PVC, ABS, polycarbonate and polypropylene.
Simply put, a tolerance is a measurement that indicates the level of precision required for the part you want to manufacture. Specifically, machining tolerances represent how much variation is allowed in the final dimensions or measurements of a part.
5. What kind of finish does CNC machining leave behind?
Due to the rotational motion created by the CNC milling tool, the surface finish of a CNC machined part will have visible tool marks. If you need a smooth, blemish-free finish on your parts, we recommend choosing a secondary finish: grained or powder coated.
Yes, we offer CNC turning (lathes), as well as CNC machining with 5-axis, 3-axis and CNC routers.

Overview: What is CNC Milling?
Basic knowledge of CNC milling machine
A CNC milling machine is an automatic cutting machine that uses a rotating spindle head to cut unwanted material. CNC mills come in many sizes and with different axis configurations. This manufacturing process is primarily used for cutting harder metals, but is also suitable for workpiece materials ranging from plastic and aluminum to stainless steel and titanium.
How CNC Milling Works
CNC mills excel at contour cutting harder materials. Like all CNC machines, CNC mills are controlled by G-code created through CAM software. The Gg code instructs the machine where to move the tool head, how fast to rotate the tool, how deep to cut, how to move the workpiece, and other factors related to speed, feed rate, and coordination. The complexity of the G-code depends on the number of axes of the milling machine.
Milling machines can still be used for contour cutting of softer materials, but are not as cost-effective as CNC routers for this purpose. The main difference between these machines is that with a CNC router, the workpiece remains stationary while the router cutting head is oriented around the workpiece, whereas a CNC milling machine can move both the tool head and the workpiece. While CNC milling machines are primarily used in industrial manufacturing, CNC milling is more commonly found in low-volume manufacturing such as woodworking.
Types of CNC Mills
The most widely used type of CNC milling machine. Full utilization of the X, Y and Z directions makes the 3-axis CNC mill suitable for a variety of jobs.
This type of router allows the machine to rotate on a vertical axis, moving the workpiece to introduce more continuous machining.
These machines have three conventional axes and two additional rotary axes. Thus, a 5-axis CNC router is able to machine 5 sides of a workpiece on one machine without removing the workpiece and resetting it. The workpiece rotates, and the spindle head can also move around the workpiece. These are bigger and more expensive.
Other Benefits of the CNC Milling Process
CNC mills are built for precision manufacturing and repeatability, making them ideal for rapid prototyping and low-volume production runs. CNC mills can also machine a variety of materials, from basic aluminum and plastic to more exotic materials like titanium—making them ideal machines for just about any job.

CNC Milling Operations (Types) – What CNC Milling Machines Do
CNC milling service is a type of CNC machining service ideal for manufacturing CNC milled parts with high precision and tight tolerances in prototype and small/high volume production, which is achieved by the following common CNC milling operations.
- Face milling: also known as face milling or slab milling, refers to the milling process that uses a peripheral toothed face milling cutter for cutting. The rotation axis of the tool is parallel to the surface of the workpiece.
- Face milling: An operation in which a milling cutter has teeth on both the perimeter and face, with the axis of rotation of the cutter perpendicular to the surface of the workpiece, generally used to machine planes and contours.
- Form milling: Use of form cutting tools or flying tools for specific purposes, including convex and concave tools, often used to create irregular surfaces and contours such as curved surfaces.
- Angle milling: also written as angle milling, mills a plane that is neither parallel nor perpendicular to the tool axis.
- Gear Milling: The milling process used to manufacture gears.
- Thread Milling: Thread milling cutters interpolate around or within a workpiece to create the desired threads, requiring a machine capable of simultaneous movement in the X, Y, and Z axes.
- Profile milling: Rough or finish milling of vertical or inclined surfaces, continuous toolpath.
- Span Milling: Machining two or more parallel vertical surfaces in one cut.
Other milling operations: Row milling, side milling, end milling, saw milling, helical milling, cam milling, keyway milling, grooves and grooves.
