    • A coolant system is disclosed for use with a machine tool in which coolant is used to both cool and lubricate a workpiece and cutting tool. The system of the present invention utilizes a positive displacement pump with one or more spray nozzles each having a restricted orifice whereby the coolant is sprayed from the nozzles at a relatively high velocity and pressure enabling the coolant to be precisely directed to the cutting location to provide optimum cooling and lubricating of the workpiece and cutting tool. Check valves are provided for both the pump inlet and outlet lines to maintain the pump in a primed condition and prevent drainage of coolant from the coolant system when the pump is not operating. The system filter is mounted to a flexible coolant line to enable the filter to be raised from the coolant reservoir and the filter is coupled to the coolant line by a quick connect/disconnect coupler to enable the filter to be raised from the reservoir and quickly replaced with a clean filter when the first filter becomes clogged and requires cleaning.
    • 公开了一种与机床一起使用的冷却剂系统,其中使用冷却剂来冷却和润滑工件和切削工具。 本发明的系统利用具有一个或多个喷嘴的容积式泵,每个喷嘴具有受限制的孔口,由此冷却剂以相对高的速度和压力从喷嘴喷射,使得冷却剂能够精确地定向到切割位置,以提供 最佳的冷却和润滑的工件和切削工具。 为泵入口和出口管线提供止回阀,以保持泵处于起动状态,并且当泵不工作时,防止冷却剂从冷却剂系统排出。 系统过滤器安装到柔性冷却剂管线上,以使过滤器能够从冷却剂储存器升高,并且过滤器通过快速连接/断开联接器联接到冷却剂管线,以使过滤器能够从储存器升高并快速更换 当第一个过滤器堵塞并需要清洁时,使用干净的过滤器。
