Technical equipment

We use state-of-the-art machinery and equipment. Our engineers and NC programmers use CAD/CAM software. We use 5 to 7 axis CNC milling stations. 5 axis lasers are also used for cutting various shapes. The prototype press shop is equipped with presses with sufficient parameters to cater for any automotive panel. The assembly stations are equipped with modern equipment meeting the strictest requirements of the automotive industry. We are also equipped with a highly precise tool-making grinder to support the manufacture of measuring aids and fixtures plus 3D measuring instruments, optical scanning systems are also used for accurate measuring.


 

Milling stations

Large CNC 5 – 7 axis milling stations are indispensable for our type of specialization. The combination of our milling stations enables us to produce various types of tools to the required sizes and precision demanded by engineers and designers.
