In the past few years, Hembrug has spearheaded several new developments that are not only high precision but also extremely productive. For instance, at the EMO 2011, the company introduced the Mikroturn Twin Spindle and the Mikroturn 100 CNC Special.
Miktroturn Twin Spindle: up to 30% less cycle time
The Mikroturn Twin Spindle is equipped with two fully hydrostatic spindles with integrated spindle motors, linear motors in X and Z slides, as well as an integrated, fully automatic feeding robot.
In some cases, hard turning is by nature three times faster than comparable grinding operations, yet the twin spindle enables even more cycle time improvements of up to 30 percent and productivity boosts of up to 100 percent.
Miktroturn 100 CNC Special: for larger and heavier pieces
The Mikroturn 100 CNC Special is a special version with a fully hydrostatic high-performance spindle with 2000 rpm, and integrated torque motor and extended stroke of the Z slide.
Larger and heavier work pieces can be turned on it compared to the standard Mikroturn 100 CNC version.
Special solutions for both productivity and flexibility
Bert de Veer sees in these developments an important step into the future: "For a long time, we were considered a world champion in precision, but we paid too little attention to productivity. All that has changed. In our new developments, the focus is on productivity, on the one hand, and on increased flexibility on the other hand, with respect to customer wishes. We are gladly willing to provide special solutions."
As an example, he mentions a project in which different shafts for gear wheel pumps are processed. These are moved on a feeder conveyor to the machine, detected by an image-processing camera and inserted by robot. In this manner, the machine recognises the particular work piece and automatically chooses the appropriate CNC program
