CNC deep hole drilling machine SHDD series

horizontal

The new Sunnen SHDD-series is designed around the BTA deep-hole drilling process in cylindrical parts. However, it is also capable of a wide variety of other similar machine processes, including counter boring, pull boring, trepanning, bottom forming, and skiving/roller burnishing.
