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.
