With a wide range of CNC milling capabilities, Sinotekk satisfies your high-precision machining needs in the most cost-effective way. We have 40+ CNC milling machines in house with 3, 4 and 5 axis. Here's a quick guide to explain what each added axis means in terms of milling operations and what kind of parts are produced on different CNC milling machines:

3-axis mill – The rotating tool can translate relative to the part on X, Y, and Z axes. The tool is fixed in a vertical or horizontal position, depending on the machine.

4-axis mill has all the axes mentioned above but now the table can also rotate around the X-axis. This allows to machine the sides of the workpiece without repositioning. It is worth mentioning that 4-axis mills are not that common.

5-axis mill – All that was true for 4-axis mills, applies for 5-axis ones as well. Only now the workpiece can also rotate around the Y-axis. 5-axis CNC milling machines can produce highly complex parts in one go, no extra setups are generally necessary.

5 axis precision machining

Sinotekk's state-of-the-art 5-axis CNC milling machines are equipped to handle the most challenging, high-precision projects, delivering optimal results in industries that demand the highest standards of quality and performance.

Key Capabilities of 5-Axis CNC Milling:

● Complex Geometries: The ability to machine intricate shapes and contours with multiple angles, perfect for parts with complex features or non-prismatic geometries.

● Tight Tolerances: Achieve high-precision components with tight dimensional tolerances, ideal for industries like aerospace, medical devices, and automotive.

● Enhanced Surface Finish: The precision of 5-axis machining ensures superior surface finishes, making it ideal for parts requiring smooth, detailed surfaces.

● Reduced Setup Time: Multi-angle machining in a single setup minimizes handling time, reduces errors, and speeds up production.

● Efficient Multi-Side Machining: With 5-axis capability, we can process multiple sides of a part in one continuous motion, improving speed and reducing cost.

3 & 4 axis CNC milling machining

Both 3-axis and 4-axis CNC milling at Sinotekk allow us to offer cost-effective, high-precision machining solutions for industries such as aerospace, automotive, medical, and electronics, ensuring your parts are produced quickly, accurately, and to the highest standards.

3-Axis CNC Milling:

● Precision and Accuracy: High-quality parts with tight tolerances and smooth finishes.

● Cost-Effective Production: Ideal for less complex parts and smaller production runs.

● Versatility: Suitable for a broad range of industries and materials, from metals to plastics.

4-Axis CNC Milling:

Our 4-axis CNC milling adds a rotary axis to the traditional 3-axis movement, allowing the workpiece to rotate while it is being machined. This additional capability improves efficiency and enables:

● Multi-Sided Machining: Machining on multiple faces of the part in a single setup, reducing time and improving accuracy.

● Increased Complexity: Ability to produce more intricate parts with undercuts and complex angles that are difficult to achieve with 3-axis milling.

● Reduced Setup Time: Fewer part repositionings are required, speeding up the production process and reducing handling errors.

● Enhanced Precision: Consistent and high-quality results, even on parts with challenging geometries.
