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.

The SGH10 wire-actuated encoder measures the absolute direct cylinder stroke in a hydraulic cylinder. The new measuring system eliminates costly boring of the piston. As a result, integration costs are reduced compared to other measuring systems and a possible weakening of the piston is avoided effectively. Thanks to its unique lateral installation, the SGH10L can also be used in almost unsolvable applications, regardless of whether for applications in which no stoke lost can be accepted, extremely small piston diameters or in the case of cylinders with mechanical end position cushioning. Measuring range 0 … 1000 mm (39.37 inches). Almost no stoke lost thanks to lateral mounting. Absolute measuring system. CANopen interface, analog: Current and voltage. Pressure-resistant up to 350 bar, pressure peaks up to 450 bar. High degree of flexibility, adjustable to all measuring lengths thanks to teach-in. High shock and vibration resistance.
