The deterioration and/or shortened operating life of cutting fluid is partly caused by lubrication oil and/or hydraulic oil mixed in the cutting fluid.
The LHL systems minimize the amount of lubricant mixed in the cutting fluid, reducing to less than one-tenth of that of oil.
Details of investigation: Investigating the conditions of the cutting fluid sampled out of the machining centers located in the same machining line.
Being in the same machining line, maintenance for the cutting fluid of these two machines were done at the same time. The cutting fluid samples were collected randomly while the coolant pumps were running followed by being left to rest for three days. Tramp oil was observed in the sample from the machine with oil lubrication system while it was hardly observed in the sample from the machine with LHL lubrication system.
The amount of lubricant delivered by LHL system is 5% to 10% of that of the oil system. However, when it comes to the amount of lubricant actually mixed in the cutting fluid, considering LHL’s water resistance and adhesive property, the amount of LHL mixed in the cutting fluid would be even smaller.
