FAQs: common questions about CNC metal milling.
What materials can be CNC milled?
CNC milling is a versatile process capable of working with a wide range of materials, including:
- Metals: Aluminum alloy, brass, steel, titanium alloy
- Plastics: Acrylic, polycarbonate, nylon
- Others: Wood, foam, ceramics, composites
No matter soft or rigid material, a CNC milling machine can shape and mill them accurately.
What’s the material for the common types of milling cutters?
Milling cutter is a common cutting tool on metal cutting machines, so the quality of the milling cutter material directly affects the efficiency and quality of the milling process. The following are the common types of milling cutter materials:
High-speed steel (HSS): High-temperature resistance, long-lasting sharp edge, good overall performance. HSS is suitable for high-temperature alloy, titanium alloy, super-strength steel, etc.
Carbide ( WC): High density, high hardness, poor toughness, suitable for milling deep grooves and processing hard materials.
Ceramics: Offer high heat and wear resistance, suitable for superalloys and hardened steels.
Diamond: Diamond has extremely high hardness and wear resistance and can be used for machining rigid materials such as ceramics, glass, and composites.
PCD ( Polycrystalline cemented carbide ): Low density, high -hardness, high wear resistance, suitable for milling materials such as aluminum and copper.
CBN (Cubic boron nitride): Low density, good thermal stability, excellent cutting performance. Suitable for milling high-hardness materials and stainless steel.
What industries benefit the most from CNC metal milling?
- Aircraft/Military Manufacturing: Components like motors, brackets, and reinforcement plates demand CNC milling for high precision, strength, and corrosion resistance.
- Automotive Industry: CNC milling can produce engine bases, transmission axles, and steering gears, with high precision and stability.
- Mold Making: CNC milling is essential for manufacturing complex and curved surfaces in molds.
What is the best CNC Milling machines for the beginner?
- SainSmart Genmitsu CNC Router Machine: This desktop CNC milling machine is affordable and suitable for beginners and hobbyists.
- BobsCNC E3 CNC Router Engraver Kit: A budget-friendly option for those looking to start with CNC milling and engraving projects.

The CNC milling machines above are affordable and perform well; they are the best choice for beginners.
How to choose the cutting tool’s speed and width?
- Optimal Tool Selection: Choose carbide end mills or tools that don’t need regrinding for surface milling. During general milling operations, aim for two passes. Use an end mill for rough milling in the first pass, then continue passing along the workpiece surface. Ideally, each pass should be 60% to 75% of the tool’s width diameter.
- Tailored Tool application: Apply end mill and carbide blade end mill for processing bosses, grooves, and box mouth surface.
- Processing curved surfaces: The round ball nose mill cutter is for curved surfaces and variable contours.
ball nose milling cutters are for finishing
round nose milling cutters with carbide inserts are for rough machining.
How does CNC metal milling differ from traditional milling methods?
- Different operation methods: Traditional milling mainly relies on manual operations such as tool changes, processing monitoring, etc. While computer programs control the CNC milling.
- Different efficiency: CNC milling is highly efficient in manufacturing due to its automation. Operators input programs into the computer, which then controls operations like monitoring and tool changes.
- Different precision: Manually performing the traditional milling has the risk of causing errors.
- Function different: A CNC mill can manufacture complex parts with various shapes or surfaces. However, traditional milling is only for flat surfaces.
How can CNC metal milling contribute to cost savings in manufacturing processes?
- Increased efficiency: This benefits from its automated operation; after setting up the parameters and input programs, it performs 24/7.
- Improved precision: A CNC metal mill is computer-controlled machinery that performs according to program instructions. Compared to manual milling, CNC milling minimizes errors and material wastage.
- Saved labor cost: Since CNC milling is automated, it requires fewer manual operations, which leads to reduced labor expenses.
What surface can CNC milling machined?
Plane type parts: including positive, negative, oblique plane surfaces
Curved surface components: including spherical, conical, inclined surfaces,etc.
Variable beveled parts: Such as the whole beam, frame, edge strips and ribs on the airplane, etc.
