Machining Turning Industrial Precision Parts
CNC turning is a machining process that involves cutting material to create round shapes,
typically utilizing a CNC lathe.
During this process, the workpiece is positioned inside the lathe and rotates while a cutting tool
removes material, gradually shaping it until only the desired form remains.
CNC turning is particularly well-suited for cylindrical parts, typically utilizing round rod material.
However, it is worth noting that square and hexagonal bar stock can also be employed.
The primary objective of CNC turning is to produce parts with shapes that can be achieved by
guiding a cutting tool into a rotating bar of raw material.
Additionally, turning can be used to reduce the diameter of a workpiece to meet specific
dimensions.
This technique is commonly employed in metalworking, woodworking, and metal spinning,
with CNC lathes frequently utilized to produce precise round shapes, including those with exact
outer and inner diameters.

FAQ's
1. 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
2. Precision and Accuracy in CNC Turning
CNC lathes excel in precision and accuracy, particularly when working with hard materials such as
steel, aluminum, stainless steel, titanium, brass, and copper.
While plastic materials can also be used in CNC turning, their achievable tolerances are generally
lower compared to their metal counterparts, and they can be more susceptible to deformation
during machining.
Additionally, plastic materials are often chosen for certain applications due to their cost-effectiveness
when compared to metals.
Typically, CNC turning machines provide accuracy and repeatability within a few thousandths of
an inch.
With the right equipment, setup, and conditions, CNC lathes can achieve tolerances within a few
ten-thousandths of an inch or even better.
However, achieving such high tolerances can be influenced by factors like material temperature,
machine quality, and the complexity of the part being machined.
3. What is your typical lead time? Can my parts be produced urgently?
Our standard lead time for screw machine products, from quoting to manufacturing and shipping,
is approximately one week, with an on-time delivery rate of over 99%.
Depending on factors like tooling, gauges, and material availability, we might accommodate
expedited production for your parts. Feel free to inquire!
