CIRCULAR BLADE SAWS

The oil mist cleaner suitable for circular sawing machines and automatic control/cutting metalworking machines.

The circular saw is a tool used for straight-line cutting  on different types of materials, wood and its derivatives, plastic, metals, etc. . It is called circular for the blade’s shape, a toothed metal turning disk.

Starting from this cutting tool, cnc saws for metal cutting have been developed, suitable for cutting of tubes, solids and profiles in large quantities and extreme precision.

During cutting operations, adequate and controlled lubrication on the cutting blade is essential, the friction between the materials is minimized with a consequent increase in blade performance.

Here is a direct reference of  manufacturer  EXACTCUT CNC CIRCULAR SAWS, customer of us;

High-performance MINIMAL oil mist lubrication systems increase cutting performance, however without an adequate exhaust system, can occur a harmful extraction of these oil mist particles.
Another undesirable aspect is the stratification of the oil on any part of the machine, which can cause problems, for example with the identification of the material. Cleaning the machine increases cutting precision.

The oil mist formed by the lubrication of the saw blade is not only harmful in insufficiently ventilated spaces, but can also significantly reduce the life of some machine components or their functionality.To prevent these undesirable effects, it is necessary to install an on-board extraction device .

Every type of pollutant produced during saw/miter metalworking process has to be analyzed to choose the suitable mist collector.

For example, the oil mists produced during metal working with emulsified oil,  SPRAY MIX, NEAT OIL are caused by the sum of these factors:
– the evaporation of the coolant oils and the consequent production of fumes, oil mists and aerosols.
– 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.
When dry powders reach minimum dimensions become volatile and during processing/cleaning they remain suspended in the air.
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
