CNC Lathe Turning Part CNC Machining Service Custom CNC Turned
Machined Parts
CNC turning is a subtractive manufacturing process that involves
the rotation of a metal rod
while a cutting tool is applied against the material to remove
excess material and shape the
final parts.
Our CNC lathes are equipped with live tooling capabilities,
allowing for the machining of flat
features and holes directly into the workpiece.
Additionally, we offer threading services for both the outside
diameter (OD) and inside diameter
(ID) of the parts.
After the turning process, the parts can be left with visible tool
marks for a functional finish or
bead blasted for a smoother appearance.
Once the production run is complete, all parts undergo a thorough
inspection, are then carefully
packaged, and promptly shipped to their destination.
Product Details
The turning process predominantly employs metals as its primary
materials.
These metals encompass alloy steel, carbon steel, cast iron,
stainless steel, aluminum, copper,
magnesium, and zinc.
Nonetheless, this versatile process can also be applied to machine
plastic components and work
with an array of other materials, including ceramics, composites,
thermoplastics, and thermosets.

Applications of CNC Turning
Turning is employed to craft rotational components, usually axially
symmetric, with diverse
characteristics like holes, grooves, threads, tapers, differing
diameter levels, and even intricate
contoured surfaces.
Products wholly manufactured via turning often encompass components
required in limited
quantities, notably for prototypes, such as custom-designed shafts
and fasteners.
Furthermore, turning frequently serves as a secondary process for
introducing or enhancing
features on parts that were initially crafted using an alternative
method.
Some instances of items produced through turning encompass
camshafts, crankshafts, baseball
bats, bowls, cue sticks, signboards, musical instruments, as well
as table and chair legs.

FAQ's
1. Benefits of CNC Turning
CNC turning offers numerous advantages in machining processes:
1. Versatility: CNC turning centers can be equipped with various
tools, including rotating cutters
like end mills and drills.
This versatility enables the machining of asymmetrical features,
enhancing production efficiency
and cost-effectiveness.
2. Speed and Efficiency: CNC turning centers increase production
speed and efficiency, as they
are capable of handling various operations quickly and accurately.
3. Radial Symmetry: Turning excels in achieving radial symmetry,
making it ideal for creating
round and symmetrical parts with precision.
4. High Precision: Mounting the part in a chuck ensures high
precision during CNC turning,
meeting tight tolerances and specifications.
5. Surface Finish: CNC turning consistently delivers good surface
finishes, enhancing the final
product's quality and appearance.
These benefits make CNC turning a valuable process in the
manufacturing industry, offering
precision, efficiency, and versatility for a wide range of
components.
2. Difference Between Rough Turning and Finish Turning
Rough turning and finish turning are two distinct phases in the CNC
turning process, each
serving a specific purpose.
Rough turning is the initial stage where the primary objective is
to efficiently remove as much
material as possible from the workpiece.
This process prioritizes material removal over precision and
surface finish. Its purpose is to
rapidly shape the workpiece and bring it closer to the desired
dimensions, allowing for more
efficient subsequent machining operations.
On the other hand, finish turning is the concluding phase of the
turning process.
Here, the emphasis shifts towards achieving the desired level of
smoothness and accuracy in
the final product.
Finish turning fine-tunes the workpiece's surface finish and
dimensional accuracy, ensuring
that it meets the exact specifications and requirements.
In summary, rough turning focuses on material removal and shaping,
while finish turning
concentrates on achieving the desired precision and surface
quality.
3. Geometric Possibilities in CNC Turning
CNC turning machining is versatile and capable of producing a wide
range of geometric designs,
from the simplest to the most complex, often with additional
features incorporated.
Some common part shapes that can be readily achieved using a
standard CNC turning
center include:
1. Straight cylindrical shapes
2. Tapered shapes such as a cone
3. Contoured shapes such as a chess pawn
4. Shapes with threaded holes
5. Shapes with grooves such as for o-rings
6. Knurled shapes such as for handles
7. Chamfered shapes
8. Shouldered shapes
