Frequently Asked Questions
Most frequent questions and answers
What is CNC milling and when should I use it?
CNC milling is a machining process that uses rotating cutting tools to remove material from a stationary workpiece. It is ideal for producing complex shapes, flat surfaces, slots, and detailed features across multiple faces.
If your part design includes intricate geometries or requires tight tolerances, CNC milling is often the best choice.
Not sure if milling fits your project? Share your CAD files with us, and our engineers will recommend the most efficient machining solution.
What types of parts are best suited for CNC turning?
CNC turning is specifically designed for manufacturing cylindrical or round components. The workpiece rotates while a cutting tool shapes it, making it highly efficient for parts like shafts, bushings, pins, and threaded components.
For high-volume production of rotational parts, CNC turning offers excellent speed, consistency, and cost efficiency.
Have a round part to produce? Contact us for optimized turning solutions with fast turnaround and competitive pricing.
What is CNC precision machining and why is it important?
CNC precision machining refers to the production of parts with extremely tight tolerances and high dimensional accuracy, often within ±0.005 mm or better. It is critical for industries where even the smallest deviation can affect performance, such as aerospace, medical devices, and electronics.
High-precision machining ensures perfect fit, reliable function, and long-term durability of components.
Need ultra-precise components? Send us your specifications, and we’ll deliver consistent, high-accuracy results you can trust.
What is the difference between 4-axis and 5-axis CNC machining?
The main difference lies in the number of movement directions during machining:
- 4-axis CNC machining adds a rotational axis, allowing machining on multiple sides without repositioning
- 5-axis CNC machining enables simultaneous multi-directional movement, making it ideal for highly complex geometries and tight-tolerance parts
5-axis machining reduces setup time, improves accuracy, and allows for more advanced designs—but choosing the right option depends on your part complexity and budget.
Need help choosing between 4-axis and 5-axis? Our engineers can optimize your design for both cost and performance.
Can CNC milling and CNC turning be combined in one project?
Yes, many complex parts require a combination of CNC milling and CNC turning processes. This hybrid approach is often used for components that include both cylindrical features and intricate surface details.
Working with a supplier that offers both capabilities ensures better precision, fewer setups, and faster production times.
Looking for a one-stop machining solution? We provide integrated milling and turning services to streamline your production process.
How do I choose the right CNC machining process for my project?
Choosing the right CNC process depends on several factors, including part geometry, tolerance requirements, material, and production volume:
- Use CNC milling for complex shapes and multi-face features
- Use CNC turning for cylindrical parts
- Choose 4-axis or 5-axis machining for advanced geometries and reduced setup time
- Opt for precision machining when tight tolerances are critical
Making the right decision can significantly reduce cost and lead time while improving product quality.
