The functioning of CNC machining is characterized by subtractive processes, wherein the feedstock
is machined to its final form by the removal of material. This process encompasses activities such
as drilling holes, boring lots and pathways, and shaping metal stock into new material with varying
tapers, diameters, and shapes.
Unlike additive manufacturing methods that involve the addition, layering, and deformation of
materials to achieve a specified shape, CNC machining achieves shapes through the removal of
material. This sets it apart from injection molding, where material is injected in a different state
of matter using a mold and formed to a predetermined shape.

Typical Applications of CNC Turning
Turning, a precision manufacturing technique, is adept at producing rotational, axi-symmetric
parts featuring intricate details such as holes, grooves, threads, tapers, and contoured surfaces.
Its proficiency shines in crafting limited-quantity items, particularly custom-designed shafts and
fasteners utilized in prototypes. Furthermore, turning serves as a valuable complementary process,
enabling the addition or refinement of features to parts manufactured through alternative methods.
Notable examples of products shaped through turning include camshafts, crankshafts, baseball bats,
bowls, cue sticks, signboards, musical instruments, and the legs of tables and chairs.

FAQ's
1. Do you offer reverse engineering services or suggest cost saving measures?
Beyond offering reverse engineering services, we specialize in extracting design and engineering
insights from a variety of manufactured components. Our support extends to aiding in the design
phase, recommending optimal raw materials, and advising on efficient machining and finishing
approaches.
With the ultimate function of the part in mind, we often identify subtle design changes, material
adjustments, or tolerance optimizations that can result in cost savings without compromising the
quality or performance of your part.
2. How can I ensure my design is confidential?
We prioritize the confidentiality of your design, and to reinforce this commitment, we are willing
to enter into a Non-disclosure Agreement (NDA) with our customers.
This agreement can be established prior to the quoting phase or when placing an order, ensuring
a secure environment for your proprietary information.
3. What type of design files does We accept for quoting?
To facilitate precise and timely quoting, we only accept 3D CAD files in STL, STEP, or IGES formats.
For 2D drawings containing reference dimensions, please submit them in PDF format.
It is imperative to include comprehensive manufacturing information as part of the technical
documentation.
Please be aware that informal communication channels such as Whatsapp, email, etc.,
will not be considered valid for manufacturing purposes.
