5 Axis Machining
Movement
3-axis machining is a precise and versatile method for producing flat surfaces, slots, holes, and simple 3D parts. It offers high accuracy, repeatability, and efficiency, making it ideal for small-batch or straightforward part production. Advanced tooling ensures excellent surface finish and dimensional precision.
CNC turning is designed for rotationally symmetric parts, such as shafts, sleeves, and screws. It delivers high speed, precision, and repeatability, while reducing material waste and production costs. Automated systems and advanced tooling make CNC turning ideal for both precision and high-volume manufacturing.
Simultaneous, or continuous, 5-axis machining allows all five axes to move at the same time, enabling the machine to adjust its position continuously without stopping. This approach can significantly increase machining speed and efficiency, as there are no interruptions between cutting passes, while also improving surface finish on complex parts.

Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
Sanding
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets
Black-Oxide
