A Job Shop supplying parts to the bearing industry was using a high oil-soluble cutting and grinding fluid. The individual sumps lasted only two weeks before the smell from the rancid coolant forced the operator to change out and recharge the machine.
The product left a sticky, heavy film and residue which prevented the operator from viewing the machining operation through the machine tool window.
Customer was using a traditional soluble oil cutting and grinding fluid within their CNC machines.
Standard procedure was disposal of the coolant on a bi-weekly basis to improve workspace environment.
Procedure resulted in excessive costs due to downtime, disposal costs, and coolant purchases.
