In case of Claims; Weeping workpieces are usually the same During the grinding and polishing process without 1, device for grinding and polishing of special holder in the abrasive inserted workpieces by means of a moving 5 (see for example German Ausstufen 1,036 092 gutter generated current from unbound and 1047 993), while for workpieces with size grinding center], in the the ren dimensions attached to holders are usually immersed special transport workpieces and are provided under relative devices with which the movement is guided to it, characterized in that workpieces in a continuous through-feed process are characterized by a well-known ip through the with Abrasive-filled bath can be conveyed through endless, trough-shaped, elastic conveyor belt (see for example USA.-Patent- (14, 44, 114, 114 a) for receiving the abrasive documents 2 554 701 and 3128 577), Such is used with means, the devices equipped with deflection pulleys (10, 12, 40, 42, 110, 112, IiQc ₁ , hab However, there is the disadvantage that the abrasive means 112 a) runs and its trough shape is not subjected to any precisely directed movement as a result of being guided, for example guide rollers (16, 18, 20, 60, 62, 64, 60 ', 62', 64 '. that the workpieces are not readily available until 66 '. 60 ", 62", 64 ", 66") can be maintained or polished to a high gloss. Since the abrasive grains, which are known per se on an endless chain, must be continuously accelerated in alternating pairs of tines (116) on the base (118) so that they can be swiveled towards each other, and the arranged trapezoidal and overlapping 20-cell grains also have frictional force plates (120 , 121) is formed as side walls. th are exposed, the energy demand is more similar 2. Device according to claim 1, characterized ge systems also relatively high. indicates that the side walls (46) of the trough It is also already known (see. For example shaped conveyor belt (44) in known German patent specification 256 647 and USA patent manner at equal intervals inwards direction 25schrift 2 480 238), the workpieces to be polished in have creases (48) and insert a container filled with abrasive by means of the guide, guiding rollers (66 '. 66 ") to obtain a closed- in which the sliding means with the help of a jointed Tape cross-section can be overlapped. neten drive in a directional, continuous. vertical movement is offset. However, since the with 30 such devices achievable vertical speeds are relatively low for the abrasive, the result is a very low grinding or The present invention relates to a polishing action so that for machining upper equipment for grinding and polishing work surfaces of the workpieces also very long machining pieces 35 processing times are necessary by means of a moving channel. generated electricity from unbound abrasives, in Fs is finally known (see British patent for the workpieces attached to holders, inscription IiM823). to arrange the abrasive essentially dipped in a circular ring and with relative movement in relation to it, which is shaped like a channel and which are fed. is set in rotation together with the gutter. Workpiece surfaces that are too metallic can be ground and / or polished in a very simple manner, provided with several arms, with the aid of devices coaxially to the circular groove, in which a holding device is provided on which the pokömiges or pasty « Abrasives are attached to the lapping workpieces. The holding workpiece surface is brought to act. The device rotates very slowly, so that, according to He, there are basically two possible declines - one complete revolution of the holding device. depending on whether the tving to be machined, the finished workpieces clamped workpiece on the abrasive or the grinding and can be taken. Fine such means past the workpiece to be machined, however, the polishing device has the disadvantage that it is moved. Workpieces individually by hand in the workpiece-the supply 50 working according to the first method ^; ngespaiint and after completion of the upper direction usually consist of a container filled with fliidienbehandlune to be removed again, in soft the must, whereby a relatively high work-processing workpieces are used and with the help of a wall. In addition, there is the disadvantage that a suitable drive is optionally set in translation on the curvature of the mechanical or rotary movements with shifting means. ., dimensions can be edited.
