CNC Milling Service

Utilize our CNC milling services to efficiently craft industrial-grade parts and components with automated speed and precision.

What Is CNC Milling

Precision Shaping Process

Computer-controlled subtractive machining process, precisely shapes custom-designed parts by removing material from a stationary workpiece using rotating cutting tools. The process begins by fixturing a block of metal or plastic material inside the CNC mill.

Efficient Carving

Through G-code, our CNC machines efficiently carve out parts from the raw material block along multiple axes.

Maximum Efficiency with Diverse Toolsets

Equipped with diverse toolsets, our 3- and 5-axis CNC machines ensure maximum efficiency, offering a reliable solution for the fabrication of intricate shapes.

Design Considerations

Maximum Part Size		3-axis		5-axis
	Titanium Stainless Steels Alloy Steel Brass	10 x 7 x 1.75 (inch)	254 x 178 x 44.5 (mm)	2.6 x 2.9 x 3.9 (inch)	66 x 73 x 99 (mm)
	Copper	10 x 7 x 2.75 (inch)	254 x 178 x 69.9 (mm)
	Aluminum Plastic	10 x 7 x 3.75 (inch)	254 x 178 x 95.3 (mm)
Minimum Part Size	0.25 x 0.25 (inch)	6.35 x 6.35 (mm)
Minimum Thickness	0.04 (inch)	1.02 (mm)
Threading	Support UNC and UNF threads from #2 up to 0.5 inch, Metric threads from M2 to M12.
Tolerances	+/- 0.005 (inch)	+/- 0.127 (mm)
Radii	During the CNC machining process, sharp inside corners on a part will naturally be rounded or radiused.
