AR oil mist extraction Filtrations for doosan machine tools
AR Filtrazioni produces oil mist exhausters, fume purifiers for doosan machine tools, deriving from the machining of CNC machine tools.
AR Filtrazioni has been producing oil mist exhausters and fumes purifiers for Doosan machine tools for years, deriving from CNC machine tools.
Since the development of the CNC lathe in 1980, Doosan Machine Tools has become one of the leading companies in the global machine tool industry, focusing on expanding the export market, continuously developing new products, building a global network and building a strong brand.
By providing precision machining equipment in high-value industries such as automotive, aerospace and IT, it has helped lay the foundation for strengthening the manufacturing competitiveness of global industries.
The problem of oil mists in doosan machine tools: what they are and how to solve them with AR Filtrazioni
The oil mists in doosan machine tools are composed of a set of micro particles of lubricating and cooling oil suspended in the air.
This type of air pollutant is found mainly in the mechanical and metalworking industry, where processes such as turning, milling, grinding, grinding, drawing, drilling, boring, shearing, threading, cold deformation of metal materials are the primary source.

Oily mists are composed of a set of micro particles of lubricating and cooling oil suspended in the air.
This type of air pollutant is found mainly in the mechanical and metalworking industry, where processes such as turning, milling, grinding, grinding, drawing, drilling, boring, shearing, threading, cold deformation of metal materials are the primary source.
The main causes of oil mists can be traced back to the sum of these factors:
– evaporation of lubricating and cooling oils in fact during the extrusion and removal of the metal, the tool or cutter comes into contact with the workpiece; friction overheats them considerably, causing the evaporation of coolant-oils and the consequent formation of industrial fumes, oil mists and aerosols.
— atomization of the oil caused both by the high number of spindle / grinding wheel or cutter revolutions, and by the use of high pressure coolant oil pumps in the machine tool. The resultant of these two elements physically breaks down the fluids into particles, micro-powders and micro-fogs so fine as to make them volatile.
Evaporation of the containment tanks of the lubricating and cooling oils;
Blows of compressed air guns for cleaning parts and machine tools
Atomization of the oil caused both by the high number of cutter revolutions
The volatility of polluting particles such as industrial fumes, oil mists and aerosols, whether solid or liquid, involves and creates various problems for companies, operators and machine tools.
The problem of oil mists if they are not treated
First of all, they negatively affect the health of the air and the health and hygiene conditions of the operators, in particular at the respiratory level, since particles smaller than 0.3 microns can reach the pulmonary alveoli, compromising the respiratory tract. Not only that, in contact with the epidermis, they create skin irritation, dermatitis and redness.
From a purely productive point of view, the pollution in the workshop deriving from micro-dust and oily mists considerably reduces the productivity of the plant and in particular the efficiency of the machine tools, since the stratification of pollutants affects the precision and tolerance of the tools. measure, with the costly consequence of having to increase maintenance interventions on the most delicate components.
Dust, oil mist and aerosols, if not filtered and purified, make the floor slippery, dirty the surfaces of the machine tools and the walls of the shed, on which they are deposited.
Without forgetting any possible contraventions to the regulations in force that impose a concentration limit of oily mists in the workplace.
Italian TLV limit 5 mg / m3
more restrictive ACGIH limit 0.5 mg / m3
