摘要： Machine for finishing complex profiled workpieces having a rotating barrel where the workpieces are machined in an loading/unloading unit, for example, a manipulator with grippers. The barrel has a torus-shaped work area defined by a bottom and cylindrical walls fixed to the bottom and the torus-shaped work area of the barrel is closed at the top with a stationary magnetic pole piece. In the center of the torus-shaped work area there is located an electromagnetic coil and a disc mounted on the magnetic pole piece through a fixed shaft. The cylindrical walls of the torus-shaped work area are made of non-ferromagnetic material while the bottom of the shaft and the disc are made of ferromagnetic material. The advantages of the machine are that the quality of the surfaces as machined is improved without changes in the geometry of the workpieces, and machining is carried out on preselected surfaces only.

摘要： The polishing composition for a centrifugal magnetic-abrasive machine for machining complex profiled workpieces. The composition exhibits ferro-magnetic properties and could be used in all centrifugal and magnetic-abrasive machines but more particularly in the combined centrifugal magnetic-abrasive machines wherein high roughness grades of the machined surfaces are obtained from comparatively low speeds of centrifugal packing and low magnetic field intensity. The composition is made of a 84-86% mixture of abrasive grains and iron-powder; 4-6% of a mixture of chromium sesquioxide, stearine, and oleic acid; 4-6% ground fruit pits or sawdust; and 4-6% of a 3% aqueous solution of triethanolamine soap. In their respective mixtures the abrasive grains are 5-40 mm in size and amount to 16-20%, the iron-powder amounts to 80-84%, the chromium sesquioxide of the 1-10 mm grain size amounts to 55-57%, the stearine amounts to 37-39%, and the oleic acid amounts to 5-7%.
摘要翻译：用于加工复杂型材工件的离心式磁磨机抛光组合物。该组合物显示出铁磁性能，并且可以用于所有的离心和磁磨机中，特别是在离心式磁力研磨机组合中，其中加工表面的高粗糙度等级由相对低的离心包装和低磁性速度获得场强度。该组合物由磨料颗粒和铁粉的84-86％混合物制成; 4-6％的三氧化二铬，硬脂酸和油酸的混合物; 4-6％地面水果坑或锯屑; 和4-6％的3％三乙醇胺皂水溶液。在它们各自的混合物中，磨粒的尺寸为5-40mm，含量为16-20％，铁粉为80-84％，1-10mm粒度的三氧化二铬为55-57％，硬脂酸为37-39％，油酸为5-7％。
