    Are you equipped for Covid- 19 ‘Idle Time?’

    Coronavirus (Covid-19) has thrown industry into unchartered territory with many machine shops running reduced capacity, idling some machines or completely closing the doors to the business. But what about your machine tools? Here, ROCOL gives engineers some tips on what to do from both a coolant and machine tool perspective…

    If it is known that a machine is going to be stood idle for a long period of time, it should be fully cleaned out with ULTRAGUARD® SC System Cleaner and left dry. The fixtures should be removed, the machine bed and tooling should be wiped down, then coated with ROCOL MOISTURE GUARD® SPRAY. If this has not been done, engineers can either discuss options with ROCOL and/or follow a few measures:

    l Skim all tramp oil from machines as it is a food source for bacteria and large amounts of surface oil will limit the oxygen supply to the fluid.

    l Increase the strength of the fluid in the sump. Do this by turning up the fluid mixer and topping up as much as possible.

    l While topping up the machines add a dose of ULTRAGUARD® BX 2000. This should be added at a ratio of 2000:1. For example, a 300L sump would require a treatment of 150ml.

    l Where possible circulate the coolant for an hour each day. Circulating the coolant reduces stagnation and will introduce oxygen and limit the growth of bacteria.

    l Where possible fit airlines in sump to oxygenate the fluid.

    l If any sumps require a cleanout, use ULTRAGUARD® SC, follow the standard cleanout procedure and leave the sump dry until required.

    l If a full cleanout is not possible then a full system cleaner flush, potentially at 50:1 should be carried out, followed by removal of the old fluid.

    Upon returning to production as many business now are, both preserved and freshly filled sumps should be treated with additives such as ROCOL ULTRAGUARD® BX 2000 and ULTRAGUARD® FX. For engineers not so familiar with ROCOL products, the ULTRAGUARD® BX 2000 is a biocide additive that can be safely used with all types of water mix metalworking fluids to give long lasting protection against bacterial activity.

    From a machine tool perspective, the impact of any plant or equipment being dormant for extended periods can be damaging, even catastrophic. If you are conscious of the impact that prolonged downtime may cause, ROCOL has fact sheets, technical data, support and of course extensive product lines to get your business back to its optimal level of productivity. The first advice note is to ensure that your sumps and coolant systems are completely clean and free of stagnant fluid, more information on this can be found via https://www.rocol.com/knowledge-centre/rocol_expert/cutting-fluid-preservation-guidelines

    For excessive grime or dirt build-up, machine tool users should consider using the Flawfinder cleaner spray. ROCOL also has its Foam Cleaner Spray for external cleaning of any vertical surfaces and once surfaces are clean, there is ROCOL’s MOISTUREGUARD® GREEN spray or fluid to prevent corrosion and the ingress of water.
