切削机床和磨床中冷却液的分离和回收的装置
摘要：
一种用于完成切削和磨削操作的含气泡的冷却液被持续地供给至被加工部位，气泡的全向散布撞击和喷溅到此部位，且冷却液中的气泡促使已加速飞溅进入切削工具与工件的接触表面间隙，改善了加工区的冷却和润滑。气泡达不到要被加工的部位或达到该部位但经过此部位，进入回流管路，沉积在液体冷却剂中悬浮着的切屑等异物上，由此加快了这些异物的漂浮。液体冷却剂作为一种细粒湍流的汇合物且通常以一种螺旋流方式向下排出，由此形成包围铣刀或磨削刀具并到达工件表面下端的液体冷却剂圆柱罩，至少一部分这种螺旋流沿工件表面从圆柱罩的下端被涡旋式地引向螺旋流中心部位，并因此将冷却液供给到铣刀或磨削刀具的被加工部位。
摘要（英）：

A method and apparatus for feeding coolant liquid to a lathe with a nozzle (53) having a discharge port (58) of substantially rectangular cross section and a constricted curved surface portion (62) on its inner wall to produce a turbulent flow and a loosely mounted tongue piece (59) crossing the section of the discharge port and projecting outside the port. The coolant is thus discharged as a collection of particulate turbulent flows containing air bubbles drawn into the coolant liquid as it passes by the tongue piece. The coolant is caused to impinge on the rotating peripheral surface (56) which is continuous with the region of the workpiece in contact with the cutter (57).
