    Description: [0001] The invention relates to a device for conditioning the tread of a board-shaped winter sports device according to the preamble of claim 1.
    The invention also relates to a method for conditioning the tread using the aforementioned device according to claim 11.
    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 regularly made of a plastic material and in most cases equipped 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 for conditioning a tread prior art methods and devices have regularly, as for example DE 2011 6 302 U1, a rotatable grinding wheel or roller on which has a rotationally symmetrical to its axis abrasive coating, which is a ceramic, organic or metallic bond having incorporated therein abrasive grains. By means of contacting the dressing tool, a profile or structure can be incorporated into the grinding surface in the grinding wheel or roller, with which 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 relatively large 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 high wear of the dressing tool and with a correspondingly high abrasion.
    There is therefore in particular the task of creating 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 give desired structure.
    The inventive solution to this problem is carried out according to the features of claim 1.
    The inventive device has a rotatable grinding wheel or roller, which is for conditioning the tread of at least one board-shaped winter sports equipment, for example, a ski, a snowboard, a snowblade, a Firngliders or a so-called Bigfoots provided. The grinding wheel or roller has a rotationally symmetrical abrasive coating to its axis of rotation, which has a ceramic, organic or metallic bond with incorporated therein abrasive grains. In this case, the abrasive grains of 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 or Profile accepts. 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 is able to withstand the loads which result during dressing of the grinding wheel required for conditioning the tread 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 pointed 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 largely lossless and possible without significant heat generation by means of the dressing, is provided according to the invention that these components of the dressing tool, namely the metallic bond with the hard materials incorporated therein, compared to the sonotrode and / or the holder have approximately matching resonance frequencies. In this case, a resonant frequency which corresponds approximately to such a natural frequency of these components is understood to correspond to each other with virtually no loss. 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 vibratory 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 that consist of cubic boron nitride, ceramic, diamond and / or hard metal.
    It is possible that the sonotrode and 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 the storage of various dressing tools, a preferred embodiment according to the invention provides that the dressing tool at one end of a sonotrode of an ultrasonic transducer - is held detachably and interchangeably - optionally via 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 designed as a rotating roller-shaped dressing tool.
    Although it is known from DE 10 2011 115 006 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, whereas 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 structure or profiling barely perceptible to 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 expedient if the dressing tool during the dressing relative to the grinding wheel or roller complementary to the desired profile or the desired structure the abrasive coating of the grinding wheel or roller is moved.
    To give the abrasive coating of the grinding wheel or roller the desired profile or structure, it may be advantageous if the grinding wheel or roller becomes relatively complementary to the desired profile or structure of its abrasive coating process during the dressing process relative to the dressing tool ,
    However, a preferred procedure provides that the axis of rotation of the grinding wheel or roller during the dressing process held 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.
    The wear on the dressing tool can be reduced if the dressing tool is made of hard metal, ceramic, polycrystalline diamond, CVD (Chemical Vapor Depositionj diamond, natural diamond or the like hard material at least at its grinding wheel or roller facing Abrichtwerkzeugabschnitt.
    In the inventive device, 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 incorporate the desired profile in the tread of a board-shaped winter sports equipment, it is expedient if the ultrasonic vibrator, the sonotrode and the dressing tool having dressing on a relative to the stationary grinding wheel or -roller preferably along an X- and / or Y-axis movable adjustment is arranged.
    In the method mentioned above, the inventive solution consists in the use of the device described above for conditioning the tread of at least one board-shaped winter sports equipment, 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 single 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 whose abrasive coating is excited by means of a dressing tool during the dressing process by ultrasound.
    In Fig. 1, a device 1 for conditioning the tread of at least one board-shaped winter sports device is shown 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 one too

    its rotational axis rotationally symmetrical abrasive coating 3, which has a ceramic, organic or metallic bond with incorporated therein abrasive grains. In order to process the abrasive coating 3 of the grinding wheel or roller 2 and to provide, for example, with a profile or structure, which then the winter sports equipment acted upon grinding wheel or roller in the tread is to incorporate a corresponding profile or a corresponding structure is a dressing tool 4 is provided, which is made of hard material at least at its the grinding wheel facing Abrichtwerkzeugabschnitt or truing 5, wherein the truing 5 is engageable with the abrasive coating 3 in such a way that the bond and / or the abrasive grains of the abrasive coating 3 during a dressing process can be partially or completely smashed with the aid of the dressing tool. The dressing tool is made of a metallic bond with hard materials incorporated therein. As hard materials for grains are used, which consist of cubic boron nitride, carbide, diamond or ceramic. 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 dressing tool section. In order to stimulate the dressing tool 4 at its dressing end 5 such, an ultrasonic transducer or transducer 6 is provided, the vibrations of which may be amplified in a booster 7 and implemented in a standing with the ultrasonic transducer 6 in operative connection sonotrode 8 in strokes, which Hubbewegungen are aligned on the surface of the abrasive pad 3. In order to apply the energy required to dress the grinding wheel lossless as possible using the dressing tool 4 on the grinding wheel and to achieve the longest possible service life of the dressing tool 4, have the components of the dressing tool 4, namely the metallic bond with the incorporated therein Hard materials, in comparison to the sonotrode 6 and possibly to a required for holding the dressing tool holder in about 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 by means of an X-Y adjustment 9 in contrast along an X and / or Y axis. 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 vibration of the dressing tool is 41 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 this case, the apparatus and time required to condition the tread of the at least one winter sports equipment is limited. 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 state 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. claims
