Cutting machines

Humans, workplaces and environment

A clean and save working environment is part of today's quality of life. In increases the satisfaction of the employees, reduces illness and therefore contributes to a higher productivity and better working conditions. Clean workplace is also necessary condition for failure-free operation of modern cutting machines.

Ecology and labour protection

Especially during the welding and cutting process very fine particles are generated which are small and therefore alveole exchangeable. Those particles deposit on the alveole. There they could diffuse through the vascular wall, reach the bloodstream and then deposit in the body, here they can cause severe health problems and even cancer. For this reason, during every welding or cutting operation health and safety measures have to be in place by legislation. Furthermore, sensitive machines have to be protected against any harmful influences or effects to ensure that these are operating efficiently. The type of substances released during the welding process is dependent both on the type which is carried out and the material which is being welded.

Surface extraction

The individual modules of the systems are divided in sections. This allows local extraction of the fumes and gases directly at source. At the same time the extraction capacity can be reduced to lower the costs.

Surface extraction

Due to the unuque design of the extraction table, the fumes and gases are evenly extracted at the surface of the table. This ensures an efficient and safe extraction of the arising dusts without sparks reaching the filter unit.

Material support

The material support has two major advantages. Firstly, by using thin flat steel bars installed at an angle, the cutting quality on the underside of the materials is enhanced. Secondly, the bars can be exchanged easily and therefore facilitate the cleaning of the table.

The control

The sectionalised extraction is controlled by a control bar and a slide which is usually installed at the cutting portal. Or activation of the extraction is integrated electronically in the control of the cutting machine.

The modular design

The cutting tables consist of individual standard modules which can be joined together. That way, every desired cutting bed size can be built. The standardised modules can be joined quickly and easily.

The dust and slag boxes

Due to the large slag boxes cutting tables, the maintenance/cleaning intervals are less frequent. On conventional tables the dust boxes need to be emptied up to six times more often. This, of course, will cost time and money.

The cleaning

All components of the cutting bed have eyelets. This makes it very easy to take out the material support frame, grating and the dust/slag boxes. The design of the dust/slag boxes enables very easy emptying.

The extraction

The extraction tables could be connected to existing extraction systems, but an optimal result can be achieved if the table is connected to a filter system 8000 or 9000. Please contact our local distributor for details of the filter unit or call us direct.

FILTRATION UNITS FOR CUTTING MACHINES

The functionality:

The contaminated air is extracted via a duct system and led to the filter unit. The dust will be precipitated on the surface of the filter media. The intelligent control monitors the settlement of the dust on the filter surface and starts a cleaning process by means of compressed air as soon as the limit value has been reached. This all takes place without interrupting the operation of the unit. The cleaned off dust falls into the dust collecting container, from where it can be disposed easily.

Good connections

System 8000 machine are supplied ready to use with 3 phase socket and plug. Both, system 8000 and 9000 have potential free contacts which can be connected to external controls of e.g. cutting machines. That way the filter unit can be started by the cutting machine will reduce the running costs again. If the filter unit and the control need to be installed in defferent rooms or buildings, a second mobile control terminal can be connected. By connecting a modem to the Kemprer control, remote diagnostics can be undertaken.

The "upper precipators"

The filter cartridges used belong to the "upper class" in two ways. Firstly they work to the principle of surface filtration. That means, that the extracted dusts can not penetrate the filter media. Secondly, the used filter cartirdges belong to the absolute prime class. Because to achieve the surface filtration only filters with a laminated PTFE diaphragm are good enough. This method is very complex, but it is the only reasonable way of filter units of this kind.

The cleaning

The advantage of the surface filtration principle used, is the possibility to clean the filter cartridges. This is taking place during the operation of the filter unit by means of compressed air. Thus, a non-interrupted operation of the filter unit is possible and the filter cartridges are only cleaned when necessary. This procedure of cource is controlled and monitored by the integrated microprocessor control.

The disposal

After the dust has been cleaned off the cartridges, it falls into the dust collecting container. From here the dust can be easily removed and disposed. On the system 8000 one or two dust buckets are lifted and pressed pneumatically to the dust hopper from where they can be removed very easily. The system 9000 has a dust collecting container which is larger in size and has castors for easy transport. Also the bigger dust collection container has pneumatic lift.
