CNC machining is the central processing step in stair production. The machining centre is usually the most expensive single machine and carries out the decisive machining operations. Limitations of the machine are also limitations for the functional and aesthetic design of the staircase. It is important to match this investment in terms of capacity and functional scope to the requirements of your own production.
The machining centre performs following steps in one workpiece set-up: Formatting, milling, drilling, grooving, edge sanding. 5-axis technology is used for round or bent parts, e.g. string boards. Individual stair parts are built quite high, that is why the maximum workpiece height is important for stair production machining centres (more than for e.g. furniture construction). It is possible to increase the machining centre's processing options by using exchangable tool units. In large stair building companies the machining centre can be fed by robots.
