What is CNC milling?

CNC milling uses rotational cutting tools to remove material from a workpiece to produce finished parts and products. This manufacturing process works well for many materials, including metals, polymers, wood and glass. CNC milling systems generally have 3 linear degrees of freedom: the X, Y and Z axis. This allows for top-notch precision and detailing. Sunnyhowe also offers more advanced, 5-degree systems, where the tool head and machining bed (A and B axis) can also rotate. 5-axis CNC machines can produce parts with high geometric complexity without needing multiple machine setups.

Maximum part size for 3- and 3+2-axis CNC milling

There are several types of CNC milling machines, each with its own distinct maximum part size. 3-axis and 3+2 axis machines have the lowest start-up costs and can produce parts with relatively simple geometries.

3-axis milling

Size	Metric units	Imperial units
Max. part size for soft metals [1] & plastics	2000 x 1500 x 200 mm 1500 x 800 x 500 mm	78.7 x 59.0 x 7.8 in 59.0 x 31.4 x 27.5 in
Max. part for hard metals [2]	1200 x 800 x 500 mm	47.2 x 31.4 x 19.6 in
Min. feature size	Ø 0.50 mm	Ø 0.019 in
[1] : Aluminum, copper & brass [2] : Stainless steel, tool steel, alloy steel & mild steel

3+2 axis milling

Size	Metric units	Imperial units
Max. part size for soft metals [1] & plastics	2000 x 1500 x 200 mm	78.7 x 59.0 x 7.8 in
Max. part for hard metals [2]	1200 x 800 x 500 mm	47.2 x 31.4 x 19.6 in
Min. feature size	Ø 0.50 mm	Ø 0.019 in
[1] Aluminum, copper & brass [2] Stainless steel, tool steel, alloy steel & mild steel

Maximum part size for 5-axis CNC milling

The more advanced of the milling machine family, 5-axis centers can produce parts with more complex geometries. These machines require fewer machine setups so they are more productive.

Size	Metric units	Imperial units
Max. part size for all materials	2000 x 1500 x 200 mm	78.7 x 59.0 x 7.8 in
Min. feature size	Ø 0.50 mm	Ø 0.019 in

Is CNC milling expensive?

There are ways you can reduce the cost of CNC milling. If you design simple parts and utilize standard-sized tooling, you can increase the chances of successfully producing a component with minimal costs. Other CNC machining design tips include adding internal corner radii to the parts, avoiding thin walls and sections of a part and opting for bigger features instead of smaller ones.
