CNC Turning High Precision Stainless Steel Part Lathe CNC Machining Service
Custom CNC Parts
Turning is a machining technique that involves the use of a lathe to rotate a metal workpiece
while a cutting tool moves linearly to eliminate metal material along the diameter, forming a
cylindrical shape.
The cutting tool's angle can be adjusted to produce various shapes. This process can be carried
out manually or with the assistance of a CNC turning machine.
CNC machining is typically employed when precise part dimensions are crucial.
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.

CNC Machining Tolerances
Tolerances are not standardized across all processes and materials. The final tolerances on your
part depend on various factors, such as part size, design complexity, the number and size of
features, materials used, surface finish, and the manufacturing process employed.
Once your order is confirmed, we conduct a Design for Manufacturing review to identify areas
that may need modification for better manufacturability.
CNC Turning Tolerances | ||
Limits for nominal size | Plastics | Metals |
0.5mm* to 3mm | ±0.1mm | ±0.05mm |
Over 3mm to 6mm | ±0.1mm | ±0.05mm |
Over 6mm to 30mm | ±0.2mm | ±0.10mm |
Over 30mm to 120mm | ±0.3mm | ±0.15mm |
Over 120mm to 400mm | ±0.5mm | ±0.20mm |
Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
Over 2000mm to 4000mm | ±2.0mm | |
*Please clearly indicate tolerances for nominal sizes below 0.5mm on your technical drawing. |

FAQ's
1. Do you offer Quick-Turn CNC Machining?
Absolutely! We understand the importance of quick turnaround times, and we're here to meet
your urgent needs.
Our Quick-Turn CNC Machining service ensures rapid lead times, with many parts ready in
just 3-4 days.
We also provide an expedite option to further expedite your project. Our dedicated team
collaborates closely with you to ensure your tight deadlines are met effectively and efficiently.
2. What tolerances can achieve?
Tolerances are not universally fixed and vary depending on the specific processes and materials
involved. The final tolerances for your part are influenced by several factors, including:
1. Part Size
2. Design Complexity
3. Number, Type, and Size of Features
4. Material(s) Used
5. Surface Finish Requirements
6. Chosen Manufacturing Process
Upon order confirmation, we conduct a Design for Manufacturing review of your design.
This review helps identify areas that may require adjustments to enhance manufacturability.
It's beneficial if you can specify which areas in your design have critical tolerances that must be
met and which can be adjusted slightly if necessary to optimize production time and cost.
Below are some general tolerance guidelines:
General tolerances for CNC machining in metal and plastic
Tolerances for plastic injection molding
Reference charts for CNC machining materials and plastic injection molding materials
General tolerance for metal 3D printing is +/- 0.5mm
A shrinkage rate of +/- 0.15% is typical for vacuum casting
To ensure precise adherence to your manufacturing and technical specifications, all requirements
should be clearly detailed in the 2D drawings.
