Automatic Swarf Processing Systems
Effective swarf management is now of key importance and not just a side issue. Managing your swarf properly will improve your company’s image, help the environment and save you both money and effort.Industry examples illustrate the potential cost and environmental benefits of adopting a professional approach to swarf management.

In metal cutting operations where cutting fluids are used, the swarf absorbs a large amount of coolant. What is desired is dry chips that are easy to handle and cutting fluids that can be reclaimed and fed back to the cutting operation, either directly or via a filtering stage. Centrifuging, filtering of the cutting fluid and removal of the dry swarf can be handled by a continuously working swarf handling system, where manual labour often can be entirely eliminated.
Less than half of the cutting fluid in the swarf can be recovered through static settling and draining. By means of a wringer or centrifuge the recovery can be increased to 90%. LUBRISERV can show you centrifuging installations which can be paid-off in a few months.
Through continuous centrifuging of swarf and reclamation of the cutting fluid, spill is avoided. Centrifuging and recovery of cutting fluids also means that your company takes on its responsibility for the environment and care for the waterways.
Constant RPM continuous centrifuges are now the most popular choice for wringing the fluids from the crushed chips. These are available in both vertical axis and a new horizontal axis type. The horizontal axis type has the advantage of removing the drive machinery from the processing area, permitting easier maintenance. Also, the wear parts of the centrifuge are more accessible, and the horizontal axis centrifuge has no trap for the sludge, which is normally entrained with the coolant being removed. Vertical centrifuges – These are ideal for smaller capacity systems especially where the material type does not require any segregation. A popular choice for smaller machine shops with a swarf capacity up to 150 Kg/hr. Usually skid mounted for easy plug and play installation. Horizontal centrifuges – The horizontal centrifuge represents a completely new idea in swarf processing. This concept is the expression of in-depth studies aimed at the achievement of the following targets: low investment cost; low operating and maintenance costs; Reduction of the moisture residuals up to 1 – 3% max. The coolant and the chips are centrifuged in a horizontally suspended drum where the coolant is separated by means of a wedge bar screen. For an optimization of the components, the centrifuge has minimum power absorption and lower costs than other centrifuges of same capacity on the market. Thanks to the ideal place of the motor unit and of the modular basket system, it allows a simple and fast maintenance at a very low cost. The even distribution of the chips allows fast and very effective oil extraction and drying. Our horizontal centrifuges are easily cleaned and serviced, there is no sludge build-up in the drive assembly The range of SCE Horizontal centrifuges can process from 300-400 Kg/hour up to 3000-5000 Kg/hour.
SWARF CRUSHING / SHREDDING
The first stage when treating swarf is the crushing. Bushy swarf is crushed or broken down to a uniform short chip material. It is important that the crusher has the ability to dissolve large swarf bundles and give an even flow of crushed swarf. This simplifies the transport and treatment of swarf, such as centrifuging. Lubriserv Ltd have a wealth of knowledge and experience and can supply the right crusher for your process.
Crushed, short chips carry a higher price than long swarf, because it is easier to handle when re-melted in steel works and foundries. Long swarf can sometimes be used when melting in cupola furnaces but not always. In addition to the direct economical gain from crushed swarf, there are even other advantages. The volume is reduced three to six times, which gives lower cost for internal and external transportation and less storage space is required.
Bushy swarf and large swarf bundles always contain a lot of fluid and because it has a large surface and low density it will corrode fast. When such swarf is charged in melting furnaces it causes heavy smoke, which causes a heavy load on baghouses. Only after crushing the fluid can be removed and the density be reduced.
The revolutionary system to spin all types of swarf , without cross contamination!
Long and short swarf is allowed, with bar ends, without shredding or crushing.
- Single plant for different materials
- No cross contamination among materials or oils/coolant
- Capable of spinning chipped and long stringy swarf
- No crusher required
- Bar ends accepted
- Manual or automatic loading of the basket
- One single plant both for oil and emulsion
- The swarf basket is designed as the centrifuge basket.
- The spun swarf is discharged automatically via robotic automation, without any operator intervention.
- As an option, several baskets can be automatically handled, by installation of extra roller conveyors.
