AR FILTRAZIONI | GRINDING MACHINES
The filtration solution for all pollutants deriving from grinding machine
The grinding machine is a machine tool characterized by a great structural rigidity, able to obtain a remarkable dimensional and geometric precision used to carry out finishing operations.
During grinding processes, industrial dust or aerosol/oil mist pollutants can be produced, which is essential to filter. AR Filtrazioni has the best solution for filtering and purifying oil mists and dust deriving from grinding processes.
The mist collector for grinding, a machine tool for finishing operations.
The grinding machine uses tools called grinding wheels characterized by a fine and extremely hard grain that allow them to work even on very hard materials such as hardened steels.
The grinding operation is necessary in order to bring any component in its state of shape or optimal surface foreseen by the project. This operation usually follows the roughing operations.
The different types of grinders
Depending on the type of processing and the surfaces to be treated we find a precise classification of the grinding machines:
- – internal grinder
- – external round grinder
- – universal grinders
- – centerless grinders
- – vertical axis surface grinders
- – horizontal axis surface grinders
- – edgewheel grinders
- – special grinders
After this classification, we see how this information influences and determines the choice of a type of oil mist extractor and its options.
First of all, it is important to know the working area or operating field. The dimensions of the grinding wheel and axes affect the maximum size of the working pieces, of the type of metal working and onsequently the power of exhaust system to be equipped in terms of cubic meters/hour.
The list of all the technical characteristics is essential for AR FILTRAZIONI, to formulate an ad hoc offer.
In particular, some salient aspects are taken into consideration such as:
1) type of coolant (neat or emulsified oil) or not.
2) Power – grinding wheel rotation speed
3) number of axes controlled
4) the material constituting the grinding wheel, CBN, diamond coated ..
5) the presence of high pressure pumps for lubrification
6) the type of material processed
7) the volume of the machine and if is closed or open
8) distinction between the various typologies of grinding machine
All these informations are important and have be taken seriously into consideration whenever you are going to buy a mist collector for your machine tool.
Depending on the type of production and processes required, particular types of pollutants will produce during grinding machines processing and consequently a suitable mist collector has to be installed.
For example, the oil mists produced during metal working with emulsified or neat oil, are caused by the sum of these factors:
1) The evaporation of the coolant oils and the consequent production of fumes, oil mists and aerosols.
2) Atomization of the oil caused by the high number of spindle/cutter revolutions and by the use of high pressure pumps of coolant oil on machine tool.
The resultant of these two elements physically breaks down the fluids into particles, micro-dusts and micro-mists so thin as to make them volatile.
Particular processings or types of material impose a dry metalworking , without liquid coolant.
The dry powders of metal working and of the resins constituting the grinding wheel become volatile if they reach a minimum size and remain suspended in the air during processing/cleaning.
We need underlining that in dry mechanical processings, powders and dusts are not the only pollutant; industrial fumes and aerosols also derive from the evaporation/combustion of protective grease/spray residues and coolant oils, remain on the surface of the workpiece throughout production chain.
The problem of oil mists-dusts-fumes if not held in mechanical workshops.
The volatility of polluting particles such as industrial fumes, oily mists and aerosols, whether solid or liquid, entails and creates various problems for metalworking companies, operators and machine tools.
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 the 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 irritations, dermatitis and redness.
From the standpoint of production, micro-dust and oil mists pollution in the workshop considerably reduces the productivity and in particular the efficiency of the machine tools, since the stratification of pollutants invalidates the precision and tolerance of the measuring instruments, with the onerous consequence of having to increase maintenance on the most delicate components.
Dusts, oil mists and aerosols not filtered and purified, make the floor slippery, dirty the surfaces of the machine tools and the walls of the shed, on which they settle.
Without forgetting any possible fines deriving from current regulations, which impose a concentration limit for oil mists in the workplace.
Italian TLV limit 5 mg / m3
more restrictive ACGIH limit 0.5 mg / m3
