Abstract:
본 발명은 적층시트 연마방법 및 장치에 관한 것으로서, 보다 상세하게는 연마대상시트를 적층하여 연마하는 연마방법 및 장치에 관한 것이다. 본 발명은 미리 설정된 제2공급위치(S2)에 위치된 연마대상블록(40)을 고정하여 가공위치로 이동되는 지그부(240)와; 상기 지그부(240)에 의하여 고정된 연마대상블록(200)에 포함된 복수의 연마대상시트(30)들의 측면을 상대회전에 의하여 가공하는 측면가공부(250)을 포함하는 것을 특징으로 하는 적층시트 연마장치를 개시한다.
Abstract:
Machine for polishing/ flattening slabs of natural stone or marble or granite or the like, provided with a mechanism for controlling the position of the spindle, such a machine comprising a base on which the slabs are positioned, a bridge, movable with respect to the base and to the slabs, on which a series of spindles (1) are fixed that, through suitable operating heads (2) kept in contact with the surface of the slabs by pneumatic cylinders that carry out the vertical movement of the spindles in the direction of the underlying slabs, provide for the polishing of the slabs themselves.
Abstract:
The polishing machine processes a workpiece put on table of body by four-directional control and is provided with a pair of columns. It comprises: first carrying unit having both ends fixed to pair of columns and having carrying part mounted on upper side; a second carrying unit being fixed to the carrying part in the direction orthogonal to the first carrying unit; third carrying unit being fixed to one end of the second carrying unit in the direction orthogonal to the second carrying unit; a tool head unit being mounted to lower side of the third carrying unit to be inclinable at predetermined angle by a tilting unit rotating at a constant angle and having driving means for rotating a polishing tool mounted at one side; and automatic constant pressure regulating means providing a predetermined virtual pressure with respect to the polishing tool mounted on the tool head unit.
Abstract:
Device for reducing the roughness of plane or cylindrical surfaces of a body (12) machined on machine tool, provided with grinding wheel (6) having suitable granulometry on saddle (5) fastened to the fixed part (8) of said machine in a translatable way in respect of said body and with means (1, 2, 3, 4) suited to push the wheel-carrying saddle (5) constantly during the operations of polishing so that the grinding wheel (6) adheres on the surface to be polished uniformly on all its parts, thus following the technical surface and not the ideal one of the body.
