CNC turning is a machining process where a rotating workpiece is secured in a chuck or collet,
while cutting tools precisely remove material to achieve the desired shape.
The movement of the cutting tools is controlled along various axes through a computer numerical
control (CNC) system, enabling operations such as turning, facing, threading, and grooving.
Product Details
CNC turning is a versatile machining process that can effectively work with various materials.
These materials include metals like aluminum, steel, brass, and titanium, as well as plastics
such as acrylic, nylon, and polycarbonate.

Typical Applications of CNC Turning
Turning is a machining method that generates rotational, predominantly axi-symmetric
components, featuring diverse attributes such as holes, grooves, threads, tapers, various
diameter steps, and intricately contoured surfaces.
Products entirely crafted through turning commonly involve components produced in limited
quantities, especially for prototypes, such as tailor-made shafts and fasteners.
Moreover, turning frequently serves as a supplementary process to introduce or refine features
on parts originating from alternative manufacturing methods.
Examples of products manufactured through turning encompass camshafts, crankshafts, baseball
bats, bowls, cue sticks, signboards, musical instruments, and the legs of tables and chairs.

FAQ's
1. Quick Reference to CNC Machining Parameters
CNC machining parameters, crucially determined during G-code generation by machine operators,
encompass the build size and accuracy of CNC machines, distinguishing them from 3D printers.
CNC milling systems offer a generous build area, capable of machining parts with dimensions up
to 2,000 x 800 x 100 mm (78” x 32” x 40”). On the other hand, CNC turning systems specialize
in machining parts with a diameter of up to Ø 500 mm (Ø 20’’).
CNC machining excels in delivering high accuracy and tight tolerances. These machines can
achieve tolerances finer than half the diameter of an average human hair (± 0.025 mm or .001’’).
In instances where technical drawings lack specified tolerances, operators typically machine parts
with an accuracy of 0.125 mm (.005’’).
2. How much do CNC machining materials cost?
The cost of CNC machining materials is diverse and depends on the chosen material, with variations
in prices based on their physical properties. A wide range of materials is available for CNC machining,
each carrying a distinct price tag.
Aluminum 6061 stands out as the most economical choice for producing metal parts.
If affordability is a priority, ABS is the most budget-friendly option. The ease of machining also
influences costs, as seen with stainless steel. Due to its hardness compared to aluminum, machining
stainless steel is more challenging, contributing to an elevated total cost.
