    • It is one object of a grinding machine and a grinding fluid supply-nozzle therefor according to the present invention to supply grinding fluid to a moving grinding point reliably, even if the surfaces of a grinding wheel is abraded up.A wheel head 5 advances/retracts to a workpiece. A grinding wheel G is carried rotatably by the wheel head 5 and grinds an eccentric portion W of the workpiece. A grinding fluid supply-nozzle 50 supplies grinding fluid to a moving grinding point K where the grinding wheel G contacts the eccentric portion W of the workpiece. The grinding fluid supply-nozzle 50 is made from a curve portion 53, an opening 51 and a straight portion 52 between the curve portion 53 and the opening 51. The grinding fluid supply-nozzle 50 spouts the grinding fluid to a grinding fluid supply point Pc upstream the grinding points K and Ks, even in the case that the grinding wheel G has been abraded up. Besides, the angle between the tangent of the grinding fluid supply point Pc and the grinding fluid spouted from the grinding fluid supply-nozzle 50 is smaller than a right angle.
    • 根据本发明的研磨机和研磨液供给喷嘴的一个目的是即使砂轮的表面被磨损也能够将研磨流体可靠地供给到移动的研磨点。 轮头5前进/缩回到工件。 研磨轮G由轮头5可旋转地承载,并研磨工件的偏心部W。 研磨液供给喷嘴50将研磨液供给到砂轮G与工件的偏心部W接触的移动研磨点K. 研磨液供给喷嘴50由曲线部53,开口51和弯曲部53与开口51之间的直线部52构成。 研磨液供给喷嘴50即使在砂轮G磨损的情况下也将研磨液喷出到磨削点K,Ks上游的研磨液供给点Pc。 此外,研磨液供给点Pc的切线与从研磨液供给喷嘴50喷出的研磨液的角度比直角小。
