The stairs have a central column or support column called newel. The column supports the handrail. Where the stairs go straight, newel is the main pillar at the bottom of the stairs. The other uprights (called handrails) between the base and the platform make the handrails well supported in the structure and decoration. Sometimes the newel in the middle position is also used for the landing site. At the top of the stairs, the pillars are used as decorative features instead of structural pieces.

With the improvement of our economic level and the popularity of CNC machine tools, more and more five-axis CNC machines are used by people. Although it is expensive, its powerful functions are the reasons why customers choose it. The main factors affecting the engraving performance of the material are the material type, hardness and toughness, and the internal structure of the material.

Compared with 3 axis CNC machine, the biggest difference between multi-head CNC machine is that it has multiple machining spindles. This multi-spindle can realize automatic tool change function, therefore, the multi-head CNC machine is also a simple and cheap ATC CNC machine.
