CNC vrtací automat

Drilling units with CNC-controlled axes for positioning the drilling heads. Depending on the model, the moving axes move the clamped workpiece or the machining units. The holes are not drilled in a single working cycle, as is the case with classic dowel drilling machines, but the entire drilling pattern is drilled individually in a single clamping. For this purpose, a drilling head (or several drilling heads) moves CNC-controlled to each individual drilling position (PTP control). For drilling rows of holes in the surface, several drills are often arranged in a 32mm hole grid in order to reduce the number of drilling cycles and traverse movements required and thus the machining time. In addition to horizontal and/or vertical drilling heads, CNC automatic drilling machines can also be equipped with units for driving in dowels, sawing or inserting fittings. Construction methods
