EWS takes measures against vibrations in deep drilling procedures Deep drilling procedures with drilling rods with a long overhang are one of the most demanding tasks in cutting technologies. What influences vibration, what amplitudes does it create, what is the effect of superimposed vibration and when are uncontrollable resonances encountered? All these are questions that are difficult to answer using theory alone. These findings formed the basis for the new development of EWS Rigid. The objective was to create a drilling holder with a passive damping system to counteract the vibrations that are created. This involves using variable vibration dampers with linear degrees of freedom in a floating mounting inside the cutter carrier. The damper position is set using a radially mounted setscrew, which allows optimum vibration conditions to be created. The improvement in surface qualities of bores is significant, as is the increase in the service life of cutter tools.

With the telescopic aerial probe, any gas traces that may be present can be better detected. This is particularly recommended in pedestrian zones. Due to the high suction power of the extraction system, the gas concentration in the ground is already very diluted. However gas may still be later detected - but not with the telecopic aerial probe. Depending on the requirements, the telescopic aerial probe can be clicked into place quickly.

For optimal functioning of the wipers, the holes in the guide rails should be closed with plastic covers, which are included with every delivery. As a replacement, you can also order them individually.

These systems are used especially on delicate surfaces. Due to the rubber coating occurs neither scratches nor discoloration. Moreover the slip resistance is improved thanks to rubber coating. Alternative to the standard we also offer individual solutions: » Other colours rubber coating » Rubber coating harder or softer » printable rubber coat
