    The invention relates to a device for conditioning the tread of at least one board-shaped winter sports equipment, z. As a ski, by means of at least one rotatable grinding wheel or roller, which has a rotationally symmetrical to its axis of rotation abrasive coating having a ceramic, organic or metallic bond with Schleifkörnem incorporated therein, wherein the bond and / or the abrasive grains of the abrasive coating during a dressing process can be partially or completely crushed by means of a dressing tool made of hard material which can be brought into engagement with the abrasive coating.
    The invention also relates to a method for conditioning the tread of at least one board-shaped winter sports device using the device mentioned in the introduction.
    The running surface of a ski essentially determines its driving characteristics. Therefore, various methods and devices have already been developed with which the running surface, which is usually made of a plastic material and in most cases can be conditioned with metallic edges, can be conditioned. Under conditioning is understood to mean the cleaning or leveling of the tread, the incorporation of a profile or a structure in the tread or any combination of these processing steps.
    The prior art methods and apparatus for conditioning a tread typically include a rotatable grinding wheel or roller having a rotationally symmetric abrasive surface to its axis of rotation having a ceramic, organic or metallic bond with abrasive grains incorporated therein. 2
    By means of contacting the dressing tool, a profile or a structure can be incorporated into the grinding pad in the grinding wheel or roller, whereby subsequently a corresponding structure or a corresponding profile is incorporated into the running surface of the at least one ski.
    However, the previously known methods and devices are associated with a comparatively large amount of mechanical effort to dress the grinding wheel and to profile and then to transfer the incorporated into the grinding wheel profile on the tread of at least one ski. The previously known methods and devices are associated with a comparatively large wear of the dressing tool and with a correspondingly large amount of abrasion.
    There is therefore in particular the object and to provide a device and a method of the type mentioned above, which simplify and accelerate the associated with the conditioning of the tread of board-shaped winter sports equipment mechanical and temporal effort and this tread as precisely as possible the desired profile or the desired structure give.
    The achievement of this object is in the device of the type mentioned in particular that the optionally held by a holder at one end of a sonotrode of an ultrasonic vibrator dressing tool is releasably and in particular interchangeable held in the device that the dressing tool from a metallic bond with it bonded hard materials is produced, and that these components (metallic bond with hard materials incorporated therein) of the dressing tool have a compared to the sonotrode and / or the holder in approximately matching resonant frequencies.
    The device according to the invention has a rotatable grinding wheel or roller, which is used to condition the running surface of at least one board-shaped winter sports device, for example a ski, a snowboard, a snowblade, a 3
    Firngliders or a so-called bigfood, is provided. The grinding wheel has a rotationally symmetrical abrasive coating with its axis of rotation, which has a ceramic, organic or metallic bond with abrasive grains incorporated therein. The Schleifkömer the abrasive coating and / or their binding during a dressing process with the help of an engageable with the abrasive coating dressing tool can be partially or completely shattered so that the abrasive coating a the running surface of the winter sports equipment to be incorporated profile or structure to be incorporated structure corresponding structure or Takes profile. According to the invention, it is provided that the dressing tool is made of a metallic bond with hard materials incorporated therein. Experiments have shown that only a metallic bond of the hard materials provided in the dressing tool can withstand the stresses resulting from dressing the grinding wheel required to condition the running surface of a winter sports equipment. This is because the comparatively soft metal edge on the long sides of the winter sports equipment on the one hand and the hard running surface on the other hand present particular challenges due to their opposing material properties. Since the plastic used to make the tread is very pliable and tough, a grinding wheel with a very sharp abrasive coating and correspondingly sharp abrasive grains is needed. However, such abrasive grains wear easily on the comparatively soft steel edge. Since the hard materials bound in the dressing tool are held firmly in the dressing tool due to the metallic bond, it is also possible to use comparatively fine-grained hard materials for the dressing tool, which protrude less from the surface of the dressing tool and are therefore exposed to less wear. In order to be able to apply the energy required for dressing the grinding wheel as far as possible without causing any major heat development by means of the dressing tool, the invention provides that these components of the dressing tool, namely the metallic bond with the hard materials incorporated therein, in comparison to the sonotrode and / or the holder have approximately matching resonance frequencies. In this case, such an eigenfrequency of these constituents was understood as having an approximately coincident resonant frequency, which corresponds to each other with virtually no-distortion. On the other hand, if the natural frequencies are far apart, unwanted vibration divergences arise between the components of the dressing tool, through which the hard substances bound in the dressing tool detach from the bond and thus set short service lives of the dressing tool. Since the different winter sports equipment, such as a downhill ski on the one hand and a cross-country ski on the other hand, must be conditioned differently, and since the required grinding wheel is to dress differently, is provided according to the invention that arranged at one end of a sonotrode of an ultrasonic vibrator dressing tool detachable and in particular interchangeable is held in the device. In this case, dressing tool and sonotrode can form a detachably held in the device unit and be made for example in one piece, - but it is also possible that the Vorrichtwerkzeug itself is releasably held on the sonotrode.
    So that the dressing tool can withstand the occurring loads as long as possible, it is expedient if the hard materials used for the dressing tool are grains which consist of cubic boehmitride, ceramic, diamond and / or hard metal. It is possible that the sonotrode and possibly held by a holder at one end of the sonotrode dressing tool are held interchangeable in the device. However, in order to reduce the expense associated with storing various dressing tools, a preferred embodiment according to the invention provides that the dressing tool at one end of a sonotrode of an ultrasound vibrator is optionally detachably and in particular exchangeably held by a holder.
    For dressing the grinding wheel and a stationary dressing tool can be used. However, a preferred embodiment according to the invention provides that the dressing tool is configured as a rotating roller-shaped dressing tool.
    Although it is known from DE 10 2011 115 003 a device for conditioning abrasive tools with rotational geometry geometry whose abrasive coating has a ceramic, organic or metallic bond. However, such devices are only used for trimming the grinding tools required for comparatively rough grinding operations, while the device according to the invention is intended for micro-profiling of the running surface of a winter sports device in which the tread is to be given a barely perceptible structure or profiling with the naked eye.
    In order to provide the tread of a winter sports equipment at least over a portion of its longitudinal extent with the desired profile or the desired structure, it is useful if the dressing tool during the dressing relative to the grinding wheel or roller complementary to the desired profile or the desired structure of the abrasive covering Grinding wheel or roller is moved.
    In order to give the abrasive coating of the grinding wheel or roller the desired profile or the desired structure, it can be advantageous if the grinding wheel or roller is moved during the dressing process relative to the dressing tool complementary to the desired profile or the desired structure of their abrasive coating.
    However, a preferred procedure provides that the axis of rotation of the grinding wheel or roller during the dressing process is kept stationary and the dressing tool is moved along an X and / or Y axis.
    In this case, a preferred procedure provides that the amplitude of the dressing tool is 10 nm to 1 mm, preferably a few micrometers. 6
    The wear on the dressing tool can be reduced if the dressing tool is made of cemented carbide, ceramic, polycrystalline diamond, CVD (chemical vapor deposition) diamond, natural diamond or the like hard material at least on its grinding wheel or roller facing dressing tool section.
    In the device according to the invention, the dressing tool is provided at one end of a sonotrode of an ultrasonic vibrator. With the aid of the ultrasonic vibrator, the dressing tool can be vibrated in such a way that the surface structure of the grinding wheel or roller can be processed and deformed in the desired manner.
    In order to be able to incorporate the desired profile in the running surface of a board-shaped winter sports device, it is expedient if the dressing unit having the ultrasonic vibrator, the sonotrode and the dressing tool is mounted on an opposite grinding wheel or roller preferably along an X and / or Y axis. Axis movable adjustment is arranged.
    In the case of the method mentioned at the outset, the solution according to the invention consists in the use of the device described above for conditioning the running surface of at least one board-shaped winter sports device, for example a ski.
    Further developments according to the invention will become apparent from the claims in conjunction with the description and the drawings. The invention will be described in more detail below with reference to a preferred embodiment.
    The sole FIGURE shows a device for conditioning the running surface of at least one ski by means of at least one rotatable grinding wheel or roller, the abrasive coating of which is excited by means of a dressing tool during the dressing process by ultrasound. FIG. 1 shows a device 1 for conditioning the running surface of at least one board-shaped winter sports device in a simplified representation. The winter sports equipment to be processed can be designed as a ski, snowboard, snowblade, firnglider, bigfoot or the like. The device 1 has at least one grinding wheel or roller 2, which is rotatable about a rotation axis by means of a motor drive. The grinding wheel or roller 2 has a rotationally symmetrical to its axis of rotation abrasive coating 3, which has a ceramic, organic o-metallic bond with incorporated therein abrasive grains.
    In order to prepare the sliding surface 3 of the grinding wheel or roller 2 and, for example, to provide it with a profile or structure, with which subsequently the grinding wheel or roller acting on the winter sports device should incorporate into its running surface a corresponding profile or a corresponding structure. at least at its, the grinding wheel facing Abrichtwerkzeugabschnitt or truing 5 is made of hard material, wherein the truing 5 is engageable with the Schieifbelag 3 such that the bond and / or the abrasive grains of the abrasive coating 3 during a dressing process can be partially or completely smashed using the dressing tool.
    The dressing tool is made of a metallic bond with hard materials incorporated therein. The hard materials used for this are grains which consist of cubic boron nitride, hard metal, diamond or ceramic. Wear on the dressing tool can be reduced if the dressing tool is made of cemented carbide, ceramic, polycrystalline diamond, CVD (chemical vapor deposition) diamond, natural diamond or the like hard material at least at its grinding tool or wheel facing dressing tool section.
    In order to excite the dressing tool 4 at its dressing end 5, an ultrasonic vibrator or transducer 6 is provided, the vibrations of which are amplified, if necessary, in a booster 7 and in an operative manner with the ultrasonic transducer 6
    Connected sonotrode 8 can be implemented in strokes, which strokes are aligned with the surface of the abrasive pad 3.
    To be able to apply the energy required for dressing the grinding wheel as lossless as possible with the aid of the dressing tool 4 on the grinding wheel and to achieve the longest possible service life of the dressing tool 4, the components of the dressing tool 4, namely the metallic bond with the incorporated hard materials, a in comparison to the sonotrode 6 and possibly to a required for holding the dressing tool holder approximately matching resonant frequency. While the axis of rotation of the grinding wheel or roller is held stationary during the dressing process in the device 1, the dressing tool 4 can be moved along an X and / or Y axis by means of an X-Y adjustment unit 9. The adjusting movement of the dressing tool 4 in the direction of the grinding wheel or roller to be processed can be monitored by means of an acoustic sensor, which is optionally connected via a control device to the at least one motor drive of the X and / or Y adjustment unit 9 and the contacting action of the dressing tool section 5 on the grinding wheel.
    It is advantageous if the frequency of the mechanical oscillation of the dressing tool 4 is 1 kHz to 1 MHz. In this case, the vibrations of the ultrasonic transducer can be implemented in strokes on the dressing tool 4 such that the amplitude of the dressing tool at its dressing end 5 is preferably 10 nm to 1 mm. So that the dressing tool 4 can also machine and mold a hard abrasive coating with its dressing end 5 made of hard material, it is advantageous if the dressing end 5 has hard metal, ceramic, polycrystalline diamond, CVD diamond, natural diamond or the like hard material. Since the truing is excited during the dressing process by ultrasound, can be incorporated into the tread of the winter sports equipment, the desired profile with high accuracy. In doing so, the apparative and temporal 9
    Expenditure that is needed to condition the tread of at least one winter sports equipment, within limits.
    The monitoring of the dressing and grinding process is important and helps during the dressing process to get the necessary information about the progress of the dressing process and the condition of the ski to be machined. With the aid of such sensors, in particular as AE sensors, i. can be designed as acoustic emission sensors, the dressing and grinding process can be easily monitored. In this case, the sensor can be integrated into the device.
