Coolants and cutting fluids

Cut costs for coolants and ensure productivity

Coolants are vital to machining operations in the metal working industry. Replacing and disposing dirty coolants is both costly and time-consuming. Nederman has solutions for cleaning and recycling coolants while also taking care of metal swarf and other waste material from production.

  • Cuts your cost for buying and replacing expensive coolants
  • Waste material free from oil and chemicals have higher value when recycled
  • Improved productivity and product quality
  • Improved up time through rational coolant handling and constant filtration

Coolant recovery and recycling of cutting fluids

Clean filtration - cut your costs for coolants and ensure productivity

Clean coolants ensure highly-effective machining with fine tolerances, while dirty coolant wears spindles, pumps and tools. Coolants polluted by leaked oil, are broken down by bacteria, lose their original properties and start smelling. There are high costs involved in changing coolant, operational stoppages, removal and disposal.

What is it coolant management?

Present and future trends in the cost of oils and cutting compounds require the planning for recycling and reusing cutting fluids. Coolant management is the efficient means of looking after machining coolants. It requires the use of equipment to remove tramp oils, leak oils, and solids, and possibly for bacteria control.

Which contaminations are bad for my coolant or cutting oil?

Solids in the form of fine metal chips and particles from the machining process are the most common form of contamination. Tramp oils come from various sources such as lubricating oils from e.g. slide ways, hydraulic oils from leaking seals on hydraulic rams, cutting and corrosion prevention oils carried by the work piece and poorly mixed or poor quality coolant concentrates. Other contaminants that may require removal are metal soaps, flocculated material, bacterial slime, fungal growths.

What are the benefits of keeping coolants clean?

The cost of purchasing Coolant is a relatively small operational expense in your workshop, but it the way coolant is managed has a big impact on the majority of your other operational expenses, such as labour costs, life of tools and pumps, quality of the work piece, costs for health issues, etc.
The big advantages of coolant management are, longer lasting coolant, the reduction of waste, less machine down time, extended tool life, improved surface finish, less frequent machine cleaning, less risk of coolant pipe blockage and automatic top up of machine tools. Coolant management also improves the work environment by the reduction of bad smells and the reduction of risks of skin infections and other health problems.

Which solutions are available?

Coolant management can be used in almost every machining application that uses water based emulsions as coolants, wash fluids, de-burring fluids and grinding fluids. It can be applied as a single piece of equipment for a specific machine or as a compilation of equipment for a number of machines.

Nederman offers several solutions for both coolant filtration aimed at removing solids as well as tramp oil separation. The solutions can be connected to a single machine or systems serving a group of machines. Nederman’s solution for the constant filtration of coolants in full flow is the “Presto” program. The coolant is cleared of sediment, particles and leaked oil. The “Perpetuum” type systems from Nederman work in by-pass mode, circulating a part of the coolant flow from each machine and concentrating on the removal of floating tramp oils and particles. The starting point for the solution Nederman proposes will be your application and your requirements for automation level & maintenance.

Effective coolant filtration systems

Nederman’s solution for the constant filtration of coolants in full flow is the “Presto” program. The coolant is cleared of sediment, particles and leaked oil. “Perpetuum” is another solution for coolant filtration for many machines working in groups. Investing in a coolant filtration system pays off very quickly.

  • Improved productivity and product quality through rational coolant handling and constant filtration reduces stoppages for changes
  • Reusing coolants = improved profitability
