CNC Turning Services

Unparalleled precision for producing metal and plastic parts

How Does CNC Turning Work?

CNC (Computer Numerical Controlled) Machining is a means to remove material using high speed, precision machines that use a wide variety of cutting tools to create the final design, including vertical milling machines, horizontal milling machines, lathes, and lathes with live tooling. CNC turning is a process that uses a lathe where the part stock rotates while the cutting tools remain stationary. On a multi-axis CNC milling machine, the cutting tools move while the stock remains fixed. CNC turning with a live tooling lathe combines the capabilities of both CNC lathes and mills to dramatically decrease lead times and increase the amount of features that can be machined. While multi-axis and right angle mills can rapidly create complex geometric shapes, more complex cylindrical shapes can be more cost effectively manufactured using CNC turning with a live tooling lathe.

Why Work With Xometry For CNC turning?

We combine the latest CNC milling and turning processes with proprietary technology to deliver high quality, on-demand parts. Our typical tolerance accuracy ranges from +/-0.001" to +/-0.005" for metal and +/- .002" to +/- .010" for plastic, depending on customer specs. Please see our Manufacturing Standards for more details.

CNC Finishes

As-Milled

The finish option with the quickest turnaround. Parts are left with visible tool marks and potentially sharp edges and burrs, which can be removed upon request. Surface finish is comparable to 125 uin Ra finish.

Bead Blast

The part surface is left with a smooth, matte appearance.

Anodized (Type II or Type III)

Type II creates a corrosion-resistant finish. Parts can be anodized in different colors—clear, black, red, and gold are most common—and is usually associated with aluminum. Type III is thicker and creates a wear-resistant layer in addition to the corrosion resistance seen with Type II.

Powder Coat

This is a process where powdered paint is sprayed onto a part which is then baked in an oven. This creates a strong, wear- and corrosion-resistant layer that is more durable than standard painting methods. A wide variety of colors are available to create the desired aesthetic.
