CNC drilling Ø18 mm, 250 mm plate

With the ZINSER 4125B customers can not only achieve excellent plasma and oxy-fuel cuts. Drilling, threading and countersinking operations are also no problem with the ZINSER CNC drilling unit. This video shows the drilling of a hole with a diameter of 18 mm through a 250 mm thick steel plate with a cutting speed of 35 m/mm.

Tool changer

The tool changer of ZINSER cutting machines has multiple tool positions and can be loaded with drilling, countersinking or threading tools. The ZINSER CNC drilling unit can thus be loaded fully automatically through the CNC controller.

This fully automatic integration of different manufacturing processes significantly increases your workpiece quality and production efficiency.
