Process fluids used in the metal cutting and grinding industry come in different guises, all can be cleaned but the choice of equipment will depend on the application. If you are using any of the process fluids or coolants listed below and have a need to remove contaminated particulate or tramp oil then we have a solution for you.
High speed machining centres using sophisticated cutting tools benefit from high performance coolants. Predominantly soluble oil type cutting fluids are used to lubricate & cool the cutting zone. Water based cutting fluids as users well know, get contaminated in use from the machining process. Slide-way oil, hydraulic and other oil residues along with floating particulate gather over time in the coolant eventually having a detrimental effect on performance and sump life.
Keeping cutting fluids free from the contamination process extends sump life, protects performance and is certainly better for your machine shop environment and workforce. Several options are available throughout our range, more information is available from the links below.
These systems operate automatically to provide clean coolant to every connected machine tool in the machine shop while recovering contaminated coolant from each machine. Maintaining a constant coolant level in each sump and always at the right dilution the central units provide automatic topping up, tramp oil and waste removal. A clean in place system ensures optimum performance and each system requires little in day to day maintenance.
Central units in our range are:
Applied to grinding fluids or cutting fluids when the coolants is used to transport particulate and chips to the central plant for separation. ‘Full Flow’ means that the entire flow rate of each machine tool is supplied from the central plant, the units for this application are:
The Penguin (VXKN-M) is a mobile tramp oil separator based on our lamella separator system. Constructed in stainless steel it is easy to setup and operates automatically to remove tramp oil from a machine tool sump. Extremely mobile it can be moved from machine to machine to control contamination and extend coolant sump life. Automatically self cleaning all that is required is to empty then tramp oil container when full.
Grinding fluids are used to both cool an lubricate the area around the wheel and component. A secondary function is to flush away particulate generated by the grinding process, a mixture of fines from the ground component and the abrasive wheel. Clean coolant is essential to the process, any particulate in the feed coolant will almost certainly get between the grinding wheel and component making it difficult or perhaps impossible to obtain the desired surface finish. Tramp oil that finds its way into the process will also have an effect, changing the working parameters of the fluid probably with a detrimental result.
Therefore grinding machine tools employ a range of filtration equipment including hydro-cyclones, magnetic filters or paper-band filters, or a combination of these. Paper-band is particularly tedious as it usually generates more waste leading to environmental and disposal issues. Magnetic filters are useless with non magnetic materials (duh) and hydro-cyclones, while generally effective, may not settle out smaller particles from the coolant.
We can offer two solutions, one for stand alone grinding machine, the other a central plant connecting all the grinding machines on the shop floor. Both systems use a one or more drum filters using an exchangeable stainless steel mesh type filter cloth. The systems are self cleaning and with few moving parts offer a lean maintenance requirement.
For an individual grinding machine with a flow rate up to 500l/m
Grinding Filter System Pygmer (VXPY)
For multiple grinding machines up to a total flow @ 100,000 l/m
Neat Oils also referred to as straight oils are petroleum based products containing no water. They are used as supplied for applications where lubricity is more important than heat reduction. Gear cutting and deep hole drilling and grinding operations are typical applications.
Machine tool types also play a part. For example cam autos and sliding head machine tools often favour neat oils in preference to water soluble. Keeping the oil free from particulate build up will ensure optimum performance for cutting tools and grinding wheels. Neat cutting oils will perform better and last longer saving time and money.
Our DinoFilter range is the best option for these applications as they utilise filter cylinders and stainless steel filter mesh which are automatically self cleaning and require no consumable media.
Neat grinding oils are used in applications where lubricity is more important than cooling. Straight grinding oils reduce frictional heat build up and are used in severe grinding applications for example creep feed grinding.
Good filtration is most important in any grinding operation. Grinding swarf needs to be removed and particles from the grinding wheel during dressing will also require good filtration. Certainly where the finest surface finish is required then the finer the filtration the more easy this will be to achieve.
Our DinoFilter Grinding Filtration Systems connected to each grinding machine will eliminate the need for machine based filtration give the best opportunity for extreme levels of filtration.
