What Is CNC Turning?
Turning involves holding the workpiece in a horizontally-mounted, adjustable spindle. As the workpiece rotates, various cutting tools are applied to the piece to create circular shapes and features like rings, grooves, slots, contours, radii, internal bores and threads. On our Haas turning mills, an extra axis of movement allows us to work perpendicular to the lathe spindle for making square faces or boring holes. This opens up many new machining possibilities.

Turning is used for any rotationally symmetrical shape, to remove material quickly while leaving an excellent surface finish that sometimes requires no post-processing.

Why Choose CNC Turning?
CNC turning is the fastest way to remove large amounts of material on rounded stock. It’s also ideal for larger production runs when coupled with an automatic bar feeder that provides an uninterrupted supply of raw material into the machine.

CNC turning is the only industrial process to choose when making production volumes of concentric shapes or threaded features. And, because of the rigid construction of these machines there is little vibration, which means CNC turning can offer high levels of dimensional accuracy with excellent surface finishes.

What Kinds Of Material Can Be CNC Turned?
While potentially any solid, stable material can be turned, we work with hard plastics and aluminum, various steels, titanium, magnesium, brass, copper and other alloys.

Note that some hardened steels may be too hard to CNC turn, or else will require specialty cutting tools and longer processing times. Soft elastomers or plastics may also be impossible to turn since they cannot be held in a fixed position or would change in shape under the pressure of the cutting tool.
