Advantages of QiJia
Our Company was built on the philosophy of QiJia, namely Cost-Effective, High-Precision, Rapid-Turnaround, along with a dedicated team, advanced machinery and the latest techniques to ensure your CNC machining parts and projects run successfully!

1.Q: Can you do 5 axis milling?
A: Yes. We have four KOLMACH 5 axis Milling and turning centers, capable of performing most of complex operations in a single setup.
2.Q: How quickly can you do my job?
A: Contact us for the best delivery times on our rapid turnaround CNC Machining service. We can do quick prototyping, small batch runs and large volume mass production.
3.Q: Can I get tighter tolerances CNC parts?
A: Yes. QiJia is known as one of the best CNC machining factories in China in terms of good quality, fast delivery and ultra customer service. Our standard tolerances of components are +/- 0.005", tighter tolerance is acceptable, but this means higher costs and longer delivery times.
4.Q: What drawings format you need for production?
A: 2D or 3D drawing is okay. Such as PDF, CAD, STP, IGS, STL, SAT, PRT, IPT, etc.
