CNC Milling FAQs

Steel, aluminium, titanium, tungsten carbide, technical ceramics, quartz glass, copper, etc.

Five-axis milling can achieve any shape milling, where normal milling can only be done in the X and Y axis lines.

3D files (Step, Igs, etc.) required for 5-axis milling

We will normally quote within 24 hours of receipt of the drawing.

SPP Industry Ltd.

In the 1990s, SPP Industry Ltd was one of the first manufacturers to establish CNC machining in China. The company has now established five major machine parks in China, with significant achievements in the areas of 5-axis machining, precision grinding & honing, gear machining, large parts machining, custom tungsten carbide and new material development respectively.
