Coolant management is an important part of efficient CNC machine tool operation, and it is generally well known that degraded coolant can result in premature machine tool wear, causing decreased performance.
Vacuuming coolant from a sump using a Freddy provides multiple benefits; not only is coolant vacuumed up quickly at an impressive rate of 230 litres per minute, but any sludge and residue that has built up at the bottom of a machine sump is also removed. The sump can then be thoroughly cleaned if necessary.
By doing this with a Freddy vacuum, it also removes the need to come into contact with the coolant, thus removing the likelihood of a worker contracting a skin condition through prolonged contact or having an allergic reaction.
But a Freddy does so much more than just vacuuming out the coolant. The in-built filter removes fines, swarf, and any particulates larger than the filter rating of the filter bag. A variety of filter bag sizes between 1um and 1000um are offered, which ensures a significant amount of microscopic particles are removed from the coolant.
The coolant can then either be disposed of or re-used. If it is disposed of, the Freddy has a return hose which can pump out the coolant. And just as quickly as it can vacuum up, it can pump it out. The filter bag full of the removed swarf and particulates can then easily be lifted out, disposed of or kept for reclamation.
If the coolant is to be re-used it is a simple matter of pumping the filtered coolant back into the machine sump, ready to be re-used.
“The cost savings of refiltering coolant are enormous. Regular filtering means that the coolant degrades much slower, therefore lasting longer and requiring less to be bought. And because it remains uncontaminated, the associated WHS risks lessen, and your machine tools live longer,” said Dimac Managing Director, Paul Fowler
A Freddy coolant vacuum also comes with a toolkit that allows it to be utilised in other areas, whether that be using the floor tool to vacuum up spills and swarf or using the crevice tool for getting into the machine beds and guards.
Freddy is a well known and respected UK based company established in 1962, which supplies international markets with the renowned Mark I filtration machines, originally complementing the de la Pena Oil brand. Since then the company has designed and manufactured the entire Freddy family of industrial vacuums and coolant filtration machines.
“Freddy has always led the way in coolant recycling and the company’s expertise and innovation in this area is unquestioned. Quite simply, Freddy can extend the life of your coolant, lower your operating costs and extend the life of your equipment whilst at the same time protecting your employees,” Mr Fowler added.
Dimac Tooling is Australia and New Zealand’s leading supplier of accessories and workholding solutions for CNC milling and CNC turning machine tools. The company also manufactures soft and hard jaws in their own CNC equipped machine shop in Dandenong, Victoria.
“Like all the products we sell, the Freddy has the full back up and support of Dimac technical personnel to ensure the product is installed correctly and operates at optimum performance,” Mr Fowler concluded.
