Guide How to get the correct dosing of cooling lubricants

Author / Editor: Dipl.-Ing. Jens Voigt / Rosemarie Stahl

Cooling lubricants are essential in machining metals for reducing heat and to remove chips. To achieve efficient results during production, it is important to use the correct cooling lubricant dosing. This can be achieved with a proportional dosing device.

In the metalworking industry, lubricants are used to dissipate heat during drilling, milling, cutting, grinding and other machining processes. They are also used to flush chips away from the surface area of the workpiece and improve surface quality. The areas of energy efficiency and sustainability are important considerations in selecting a fluid for this application and this has led to the development of new cutting fluids.


With the successful launch of the innovative two-component-process Bonderite Dual-Cys, Henkel Adhesive Technologies has set a new benchmark in the development of metalworking lubricants. Synergies between lubricant and cleaner are used to reduce costs, improve performance, save energy, reduce waste and improve working conditions.

In this new dual process, the cleaning bath is 100% recycled into the cutting lubricant. The process enables a type of pre-cleaning with low foaming at low cleaning temperatures in the tooling machine.

Henkel Adhesives and Bonderite

According to the company, it offers a comprehensive portfolio of tailor-made solutions for its industrial customers and high-quality consumer and in addition various professional products. It is represented worldwide by its global team of partners with the aim to deliver best-in-class service.

One of the areas where Henkel Adhesives is present is Release coatings are release coatings. These are specified by manufacturers worldwide in a variety of plastic and rubber moulding processes. When applied to a mould, the release coatings form micro-thin, thermally stable surfaces that are chemically bonded to the mould surface, resulting in multiple, contaminant-free releases and reduced manufacturing costs.

Bonderite is one of Henkel's brands responsible for surface technology and process solutions including lubricatns for forging, forming and machining, as well as cleaners, metal pretreatment and coatings. Bonderite's customers come from various industries like automotive, aerospace, agricultural and construction.

Martin Desinger, Business Development Manager for Machining Lubricants at Henkel, comments: “Recycling the cleaning solution instead of disposing of it and using the synergies between the cleaner and the water-soluble cutting fluids results in high lubrication performance, superior purity of the parts and excellent corrosion protection.”

For companies, the use of Bonderite Dual-Cys results in cost reductions of up to 40% due to more efficient use of coolant, water and energy consumption as well as reduced disposal volumes. To further increase the energy efficiency and sustainability of the tooling machine, Henkel recommends the use of the LDT Dosatron Proportional Pumps for routine dosing of the lubricants.

LDT Dosiertechnik of Hamburg is a leading distributor in the supply of non-electric dosing pumps, offering its customers over 25 years of experience. The company was founded in 1991 in Hamburg and for the past 25 years has been operating within the dosing-pump industry in Germany and Europe. High expertise, a comprehensive range of products, fast response times and short delivery times have been the driving force behind the company's continued growth. In the anniversary year of 2016, LDT Dosiertechnik moved to new premises with a servicing workshop and expanded warehouse capacity. Since the founding of the company, LDT Dosiertechnik has become a market leader for non-electric proportional dosing pumps in Germany.
