Flexible paper drilling machine 207-20 with a programme-controlled drill head carrier via a servo axis
Ideally suited for drilling multi-hole patterns and Wire-O
The 207 series drilling machines are characterised by a comprehensive range of standard features and user-friendly design. They feature a tangential chain drive, which allows for easy adjustment and replacement of the drill heads. Thanks to the wide adjustment range of the drilling spindles, a considerable insertion depth of 300 mm and the number of drill heads – up to nine are possible – the range of applications for the 207 series is also considerably broader. For all common standard drilling patterns, the drilling heads can be fitted to the machine using interchangeable indexing strips. This simplifies changeovers and prevents errors when setting the drilling distances.
