Diversified CNC Milling Ability

We provide 3/4/5-axis CNC milling and horizontal CNC milling services to help you quickly obtain custom CNC milled parts from simple to complex.

5 axis CNC milling

5-axis machining provides manufacturing feasibility for designing parts with very complex 3D geometries with high economic efficiency.

4 axis CNC milling

Four-axis milling is suitable for mass production of polyhedral milled parts, milling three three-dimensional surfaces at a time

3 axis CNC Milling

3-axis milling is the most widely used CNC machining process and is generally used for machining simple parts. Equipment cost is low.

Horizontal CNC Milling

Horizontal CNC milling is a CNC milling method in which the cutting spindle is kept parallel to the table. The rigidity of the machine tool is superior.
