To meet all of our customers' needs, we also have four Propen micro-percussion marking machines. These machines allow productive and efficient marking onto the surface of machined parts, with hardness of up to 62 HRC, with a variety of texts and symbols from the drawings. Due to the productive positioner with automated tightening system it is possible to stamp the data not only into flat surfaces but also on circumference of rotating and n-sided parts. In case of large batches of machined parts with requirements to have the text stamped on the outer circumference we make use of special hobbing punches designed just for CNC machines.
