Production approach
Production of stairs on the CNC machining centre
This procedure is widely used today. Often wooden stairs are custom-made, as the dimensions are taken at the building site of the house and then a completely individual building element is constructed. The components - stringers, steps and handrails - are particularly complicated, different and three-dimensional. For this reason, the use of CNC-controlled machining centres became established early on for stairs. Staircase construction was one of the first applications in woodworking where this modern type of machine, which was developed for metalworking, was adapted for woodworking. In staircase construction, particularly powerful machines with more than 3 controllable axes are used in order to be able to manufacture the round or curved parts that occur in staircase construction. The machines must be robust and precise in order to be able to machine the considerable wood thicknesses with low manufacturing tolerances.
After the staircase has been designed using special software, this data is used directly to control the machines.
