控制向加工槽内供给的加工液的供给量进行液温恒定控制的电火花线切割机
摘要：
本发明提供一种电火花线切割机，从清水槽或污水槽向加工槽供给温度被控制的加工液，将加工槽内的加工液的温度控制为一定，在该电火花线切割机中，利用温度传感器检测加工槽内的加工液的温度，求出该检测温度和预先设定的基准值的差ΔT。若该差ΔT大于预先设定的容许值Δt(≥0)，则驱动加工液积存用泵，使得其转速与上述差ΔT成比例。另一方面，若该差ΔT不大于容许值Δt，则停止驱动加工液积存用泵。
摘要（英）：

The invention provides a wire cut electric discharge machine, providing processing liquid with a controlled temperature to a processing bath from a clear water slot or a sink, and controlling the temperature of the processing liquid in the processing bath to a certain point, in the wire cut electric discharge machine, a temperature sensor is used to detect and process the temperature of the processing liquid in the processing bath, and difference Delta T between the detected temperature and a preset reference value is computed. If the different Delta T is greater than a preset allowable value Delta t (>= 0), then drive a processing liquid accumulation pump, making the rotating speed is proportional to the difference Delta T. On the other hand, if the difference Delta T is not greater than the allowable value Delta t, then stop driving the processing liquid accumulation pump.
