What is CNC Turning?
CNC turning, in the operation of a machine shop, is a method of
machining a part in which a pointed cutting tool is fed parallel onto
the surface of a material being rotated. This rotation is performed
by a lathe, considered to be the oldest machining tool dating far
back to ancient Egypt. The lathe secures and spins the part being
machined, allowing for a simple single-point cutting tool to remove
and shape the material, creating the desired part. This is
accomplished along a dual axis of movement that may be a straight
line, or along a prescribed set of curves or angles. Turning allows
for the creation of varying complex shapes including plain, tapered,
contoured, filleted, threaded, and radius profiles. Turning in its
purest form involves the spinning of a lathe and the steady hand of
the operator applying the cutting tool to the material being machined. Advances in technology have led to the
creation of CNC, or Computer Numerical Control, lathes and turning processes. Beyond programming commands
into the CNC lathe, the operator is taken out of the equation. An automated system now holds the cutting tool
firmly in the lathe and follows a pre-programmed design, allowing for a precise turn, exact tolerances, and an
abundance of shapes; straight, conical, curved, or grooved.
About Advanced Precision Machining’s CNC Turning Solutions
Advanced Precision Machining (APM), a Longmont, Colorado machine shop, proudly offers a wide range of CNC
turning solutions utilizing the latest in precision manufacturing technology. The dual axis CNC lathe is at the heart
of APM’s turning operations and we run two of the best machines in the business. Southwestern Industries’ Trak
TRL 1440EX lathe is our simple, low cost answer to manually turning a part. With the look and feel of a manual
lathe, the 1440EX allows for CNC operation, a 14” swing, and a 40” travel. It’s easy to learn and a joy to use,
resulting in the highest quality turned parts. For larger projects, we rely on Yama Seiki’s GA2600 ultimate turning
center. With the capacity to manage heavier duty applications, this lathe combines accuracy, a high torque motor,
and a super rigid box, allowing us to achieve faster cycle times. Thus, money saved in labor time is passed along
directly to our satisfied customers. Our fully certified machinists will be happy to discuss any turning project with
you.
