High Pressure Through Coolant System for Precision Machining
Through Coolant Filtration Systems
A Through Coolant Filtration System filters coolant to 10 microns or finer, ensuring clean coolant delivery for high-precision machining. These systems include options like cartridge filters, bag filters and compact band filters, which are selected based on chip volume and filtration needs. Integrated with a high-pressure pump, the system ensures the desired coolant flow and pressure for optimized performance. The high pressure pump in CTS supplies clean coolant through the spindle with the desired flow and pressure

FAQs
CTS delivers high-pressure, fine-filtered coolant through the spindle, unlike systems that cool externally at lower pressure. This improves chip removal, cooling and cutting precision.
LEX CTS systems operate from 15 to 200 bar, depending on the system configuration and machining application.
CTS units use multi-stage filtration from 100 microns down to 5 microns, ensuring protection of small coolant channels in tools.
By providing clean coolant under precise pressure, CTS reduces thermal load, extends rotary joint and tool life and stabilizes machining performance.
Yes. LEX designs CTS systems for seamless integration with existing coolant lines and CNC setups.
