Through Spindle Coolant (hereinafter referred to as TSC) is a configuration that can greatly improve machining efficiency and tool life.
The high-pressure cooling pump first filters the coolant in the filter to remove impurities in the coolant, and then pressurizes the coolant to deliver the pressurized coolant to the tool with internal cooling function. The chips also flow back to the water tank along with the coolant, which is the whole circulation process of the coolant.
The importance of filtering. The ideal coolant does not contain any solid impurities, but in actual use, the coolant will inevitably be mixed with cutting chips, especially when processing cast iron and plastic parts where chips are powder. The impurities in the coolant will eventually act on the cutting area through the cooling hole of the tool, so the impurities will also be cut repeatedly. The larger the volume of the impurities, the more impurities will be repeatedly cut in the coolant in the entire cycle. The wear and tear of the workpiece and the processing effect of the workpiece will be more obvious, which is closely related to the filtering function of the filter screen.
If the filter screen can filter out impurities with a diameter of more than 5 microns, then the impurities in the coolant acting on the cutting area will not exceed 5 microns; Impurities with a diameter below 106 microns in the coolant will be included in the coolant. Therefore, the quality of the coolant used in the cutting area depends largely on the filter screen. The smaller the filter hole of the filter screen, the smaller the volume of impurities in the coolant, and the less the number of impurities will be.
With the circulation of the coolant, more and more impurities will be attached to the filter. Haas can detect the blockage of the filter screen in time through the vacuum sensor in the filter part, and notify the operator in the form of an alarm in the system to deal with it.

Not only that, Haas's main screen will also display the real-time coolant water level and pressure, and according to the user's settings, when the water level or pressure exceeds the set value, an alarm will be displayed on the screen to remind the user to deal with it in time.
The pressurization capacity of the high-pressure cooling pump is also an important indicator of the TSC system. For example, a 1000psi high-pressure cooling pump can provide a pressure of 1000psi, but this requires the hole diameter of the coolant outlet. The maximum flow rate and the maximum pressure that the high-pressure water pump can provide are fixed. When the diameter of the cooling hole of the tool is larger, the flow rate of the coolant will increase accordingly, so the pressure of the coolant will inevitably decrease.
