How it Works
The Through-Spindle Coolant (TSC-300/1K) with Auto-Clean
filter uses a gear-driven pump that is mounted in the coolant tank
to move pressurized coolant through the cutting tool. The coolant
then returns to the coolant tank. The coolant continuously cycles
through the coolant system.
1.
TSC Auto-Clean Coolant Pump:
Pressurizes and pumps the
coolant from the coolant tank through the TSC system. The auto-
clean pneumatic cylinder eliminates the need for an inline filter.
When the pump stops, the pneumatic cylinder activates, cleaning
the filter and preventing chips from entering the TSC system. A
vacuum sensor detects if the filter is clogged.
2.
Check Valve:
A one-way valve that lets coolant flow through in
one direction. It does not let the coolant flow back down into the
tank when the pump is powered off. The pressure sensor in the
check valve tells the control that the system is working.
3.
Vacuum Generator:
This creates a vacuum effect to remove excess coolant from the TSC system.
4.
Precharge Solenoid (40-Taper belt-driven):
During TSC operation, the precharge solenoid applies low-pressure air
to the Tool Release Piston. This helps to maintain a seal between the TRP and the top of the drawbar.
or
TSC Union Solenoid (50-Taper or inline):
During TSC operation, the coolant union solenoid applies low-pressure air
to the coolant union. This helps to maintain a seal between the rotating and non-rotating parts.
