CNC lathe machining is the primary machining method for round feature parts, mainly machining various threads and round components such as shafts, worm gears, and balls. Compared to CNC milling, CNC turning is a more efficient method.

Machining Materials:
Stainless Steel: SS304, SS303, SS301, 4140, 4130, 45 steel, etc.
Aluminum Alloy: AL6061, AL5052, AL7075, AL2017, AL6082, etc.
Plastics: ABS, POM, PP, PEEK, PEI, PC, PMMA, PA, PE, etc.

Regardless of the manufacturing process used to produce end-use parts, CNC machining is widely used by designers as a means to create early and late-stage prototypes with short turnaround times. CNC prototyping allows designers to iterate ideas quickly without incurring tooling costs or waiting time. It is one of the best methods for creating conceptual models and functional prototypes to validate designs. Compared to other rapid prototyping methods, CNC machining enables us to obtain prototypes with tight tolerances in actual materials.

Unless the product is designed solely for 3D printing or other methods, CNC prototyping is the preferred option for extending the design life of other rapid prototyping methods.

Standard Tolerances: With high-precision milling and lathes, we are able to achieve ultra-tight tolerances for prototyping and production. Parts will be manufactured to our customers' specifications. If 2D engineering drawings are unavailable, ISO 2678 can also be used for guidance. The table below is an example of the ISO 2678 standard for your reference.

Precision Machining

In addition to standard tolerance CNC parts (such as ISO2678M or ISO2678F), Tengxing also offers high-precision CNC machined parts.

After more than a decade of experience in manufacturing, we have discovered a process method for producing precision parts.

Precision equipment + correct process = precision parts.

Tengxing has a wide variety of CNC machines and experienced engineers who never compromise on tolerances or part quality.

Plastic Machining
Many plastics are suitable for CNC machining, and machined plastic parts can often outperform their molded or printed counterparts. At Tengxing Precision, we can machine parts using high-quality materials such as POM, PEI, and PEEK.

Machining is often the best choice for high-quality plastic prototypes with detailed functions, both due to the technological advantages of the process and the associated versatility of the material.

All machined plastic parts are meticulously handled by our team of professional machinists.

Aluminum Machining
Aluminum is one of the most popular machining materials due to its machinability, strength, and versatility, while its low cost makes it ideal for prototyping and production. From standard grades such as 6061 to high-quality aerospace grades such as 7075, we offer a range of aluminum alloys for every CNC machining project.

Aluminum is not as hard as steel, so we can cut aluminum parts much faster than steel or stainless steel when milling them. On the other hand, 5 & 6 series aluminum offers a perfect anodizing finish and is widely used in electronic devices.

Our team has extensive experience in aluminum machining, as over 70% of the parts we manufacture are made of aluminum.

5-Axis Machining

5-axis machining is the optimal solution for machining complex and precision parts. When using 3-axis or 4-axis milling for parts with deep cavities or features that must be cut from multiple angles, we have to set up the machine multiple times. Moreover, the more times we need to reload the part, the lower the accuracy we achieve. With 5-axis milling, we only need to set up the machine once or at most twice, and by using an on-site inspection system, we can easily obtain the correct coordinates when reloading the part.

Most of our engineers have over 5 years of programming experience in 5-axis machining, which enables us to deliver 5-axis machined parts for metals, plastics, or other materials with fast turnaround times.
