The essence of CNC machining, or Computer Numerical Control machining, lies in its
subtractive manufacturing approach, automatically eliminating material from raw stock based
on computer-generated instructions.
Typically, CNC machines fall into two categories: those that maintain the raw stock in a fixed
position while rotating the cutting tool, and those that rotate the raw stock while maneuvering
it against a stationary tool.
Numerous adaptations and hybrid methods exist, enabling certain machines to utilize both
techniques concurrently, facilitating the production of parts with complex features.

CNC Machining Applications
Turning, a manufacturing process known for producing rotational, axi-symmetric parts, boasts the
capability to create components with intricate features such as holes, grooves, threads, tapers,
and contoured surfaces.
This method is particularly adept at fashioning limited-quantity items, notably custom-designed
shafts and fasteners used in prototypes. Moreover, turning serves as a valuable secondary process
to enhance or add features to parts manufactured through alternative methods.
Examples of products crafted through turning include camshafts, crankshafts, baseball bats, bowls,
cue sticks, signboards, musical instruments, as well as table and chair legs.

FAQ's
1. What is the difference between rough turning and finish turning?
Rough turning and finish turning are two distinct stages in the turning process.
During rough turning, the primary objective is to eliminate a significant amount of material
without emphasizing precision or surface finish, aiming to bring the workpiece closer to the
intended shape.
On the other hand, finish turning marks the concluding phase, where meticulous attention is
given to achieve the desired smoothness and accuracy in the final product.
2. What are the benefits of CNC turning?
Beyond the application of turning tools, a CNC turning center boasts the versatility of
accommodating rotating cutters like end mills or drills. This capability grants increased flexibility
in machining, allowing the handling of asymmetrical features in parts.
The incorporation of rotating cutters enhances production speed, efficiency, cost-effectiveness,
and operational safety. Noteworthy aspects unique to turning, distinct from milling, include the
ease of achieving radial symmetry, high precision achieved by mounting the part in a chuck,
and the attainment of superior surface finishes.
3. What are the minimum and maximum dimensions you can machine?
Our comprehensive CNC machining services cover milling (3-axis, 3+2-axis, and 5-axis) and
turning processes. In 3/3+2-axis CNC milling, we can achieve part dimensions up to
2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.).
For 5-axis milling, the maximum part size is 650 x 650 x 300 mm (25.5 x 25.5 x 11.8 in.).
CNC turning accommodates a maximum diameter of 431 mm (17 in.) and a length
of 990 mm (39 in.).
Smaller parts are recommended to have dimensions around 10 x 10 x 10 mm
(0.39 x 0.39 x 0.39 in.), with a minimum feature size of 0.5 mm. It's important to be aware
that our platform imposes a maximum part size of 1000 mm (39 in.), and for larger
requirements, we encourage you to contact our sales team for tailored support.
