Cutting fluids: what are they used for?<\/h2>

Cutting fluids are essential to ensure that machining operations run smoothly. They extend tool life and ensure a clean finish for machined parts.<\/strong><\/div>\n <\/div>\n<\/div>\n\n
\r\n
And that’s not all: they also dissipate the heat produced during machining, protecting the tool and the workpiece from the harmful effects of high temperatures. These fluids also make it easier to evacuate the swarf produced during machining, preventing it from accumulating, which could compromise the surface finish of the machined part or lead to an incident. Finally, thanks to their anti-corrosion additives, they preserve metal surfaces, protecting them from rust. <\/div>\r\n<\/div>\r\n\r\n\n\n
\r\n

Types of cutting fluids: whole oils and emulsions<\/h2>
\r\n
There are two main types of cutting fluids: whole oils and emulsions.\r\n\r\nWhole oils are undiluted oils, often derived from mineral, vegetable or synthetic bases, sometimes enriched with additives to optimise their properties. They are particularly well suited to processes requiring intense lubrication, such as bar turning, where their action protects tools, ensures a clean finish on machined surfaces and prevents premature wear.<\/strong><\/div>\r\n
Emulsions are a combination of two immiscible liquids: water and oil (generally between 3 and 10%), stabilised by an emulsifier. These cutting fluids are less expensive to buy and are particularly effective for cooling thanks to their high water content. However, their lubrication is inferior to that of full oils, they require regular maintenance and generally have a shorter service life.<\/strong> <\/div>\r\n <\/div>\r\n<\/div>\r\n\n\n
\r\n

Contamination of cutting oils<\/h2>
Whether in the form of whole oils or solubles, cutting fluids are loaded with contaminants during machining, such as ferrous metals, non-ferrous metals such as aluminium, or even precious metals.<\/strong> Filtration of these pollutants becomes essential, not only to clean up and recycle the liquid, but also to protect the cutting tools and extend their life. When machining precious metals, filtration of the cutting fluid enables the material to be recovered and re-melted so that parts can be re-machined, adding an economic dimension.\r\n\r\nTo choose the most suitable filtration system, a number of parameters need to be considered: the area of application, the layout of the workshop, the type and flow rate of the liquid, and the nature and concentration of the contaminants.<\/strong> Your objectives, whether in terms of recycling the liquid, decontaminating it, recovering precious materials or protecting and extending the life of your equipment, will also determine which filtration solution you prefer. <\/div>\r\n<\/div>\r\n\r\n\n\n

HIFI FILTER\u00ae offers a range of solutions to improve the quality of cutting fluids and guarantee optimum machine tool performance. These include automatic belt filters, EPC bag filters and FEC housings to capture the largest contaminants, avoiding premature saturation of in-line filters and extending their service life. At the same time, purification systems such as filtration units provide in-depth treatment of the oils. Finally, to maintain the performance of our equipment, we offer a wide range of spare parts, adapted to the specific needs of each installation.<\/div>\n <\/div>\n<\/div>\n\n

Automatic belt filter<\/h2>
<\/div>\r\n<\/div>\r\n\r\n\n\n
\r\n
\r\n
The automatic belt filter, commonly installed on machining centres, is a filtration device dedicated to industrial sectors generating a large volume of ferrous and non-ferrous contaminants.<\/strong>\r\n\r\nThe solid particles present in the cutting fluids are separated by a filter medium, allowing the chips to be recovered and the decontaminated fluid to be reused. This unit can be fitted with a magnetic separator that acts as a pre-filter, specially designed to eliminate ferrous and magnetic elements before the liquid reaches the filter belt. The process is simple: rotating magnets capture the metal shavings, which are removed by a scraper into a special tank. This pre-filtration reduces the cost of filter media.\r\n\r\nThe fluid then flows onto the filter belt, which advances automatically according to the level of cutting fluid. The volume of swarf accumulated on the filter medium raises the oil level in the PLC tank, activating a float sensor to trigger the advance of the filter belt. HIFI FILTER\u00ae also offers other types of sensor, such as pressure level sensors, providing alternatives adapted to each application.\r\n\r\nFor ease of maintenance, a sensor on the filter belt detects when the roll of media has run out and warns when it needs replacing.\r\n\r\n\ud83d\udca1 Depending on your application, rolls of filter media can be made of viscose, polyester, polypropylene, etc.<\/div>\r\n <\/div>\r\n
