At GBZ Precision Tools we develop, design and manufacture special tools for various applications. One product is for the preparation and installation of electrical power cables. These cables are for the distribution of electricity by medium-voltage networks with electrical voltages of about 10,000 to 30,000 volts, with cross sections from 25 up to 800 mm².

Also in 2017, GBZ invested in a new machine. In order to be able to better implement the customer's requirements, a new water jet cutting machine from Innomax AG, type OMAX 55100 JetMachining Center, was put into operation on 21.11.2017.

In order to remain competitive and be able to meet the customers’ demands, GBZ Mannheim® decided towards the end of 2015 to invest in an additional machine. The decision to augment the machine park by a fully automatic 5-axis grinding machine with robot-assisted loading and unloading from the company Haas Schleifmaschinen GmbH was implemented on 11 January 2016.
