3 Presentation of our company

4 MKU CHEMIE GMBH

5 Our company was founded in 1956 when we started an own production of metal working oils Caused by the very extensive growth during the first years, we built up a modern blending plant. This put us into the position to align our plant with the extended production and in accordance with the newest standards of lubricants and operational fluids. In our chemical department, we also develop and produce additives and intermediates which are exclusively used in our production. Research and development is carried out continuously in our own laboratories. We offer more than special products. Make use of our technical experience.

6 mportant principles are orientation towards quality, environment, collaborators and ustomers as well as the compliance with laws, industrial standards and the equirements of our customers. t is not up to us to decide whether we have reached the required quality this ecision is solely made by our customer. e, MKU -Chemie, want to make high-quality products in order to comply with the equirements of our customers and to increase their satisfaction. he condition for a long-term and stable relationship with our customers is that we ant to meet their requirements at 100 % - even and just when these requirements re changing. 100%

7 FIVE GUIDING PRINCIPLES... Quality brings satisfied customers Quality needs motivated persons Quality does not cost more Quality protects the environment Quality concerns all of us We also measure the quality by whether our customer comes back or our product.

11 Grinding coolants Rotex GS Grinding coolant for mineral lenses and objectives Rotex GS Grinding coolant (with antifoaming agent) for synthetic glasses Betronol MFV 1463 F Special grinding coolant for fused quartz

12 Series Rotex GS 600 excellent sludge settling behaviour fully synthetic avoids formation of scratches good corrosion protection for the machines good resistance against bacteria mild on skin Inodorous

13 Rotex GS with antifoaming agent for synthetic glasses excellent sludge settling behaviour fully synthetic good corrosion protection for the machines good resistance against bacteria mild on skin Inodorous

14 Fused quartz is a glass type which compared to the usual glass types does not contain any additions of soda or calcium oxide, i.e. which consists of pure silicon dioxide (SiO 2 ). It can be obtained by melting and solidifying of quartz (quartz sand or synthetically made), therefore the English name fused quartz or fused silica. As the structure of fused quartz compared to crystalline quartz is amorphous, the name of fused silica fits well. fused quartz fused silica fused silica It is unfavourable that fused quartz is difficult to process.

15 Betronol MF V 1463 F excellent sludge settling behaviour fully synthetic with additives enhancing lubrication avoids formation of scratches good corrosion protection of the machines good resistance against bacteria mild on skin inodorous Special grinding coolant for fused quartz

16 Slicing and sawing of fused quartz / Dionol V 1350 excellent sludge settling behaviour avoids formation of scratches good corrosion protection of the machines mild on skin Inodorous

17 Slicing and sawing of fused quartz ionol V 1519 / excellent sludge settling behaviour medicated white oil avoids formation of scratches good corrosion protection of the machines mild on skin Inodorous

18 Centring Centring is necessary in order to avoid unsteady engine running, unsteady cornering ability, increased resistance to rolling and increased wear of bearings Dionol V medicated white oil Dionol V 1350 less expensive alternative of mineral oil

19 Using grinding coolants brings the following advantages 1. Reduction of the water surface tension: Thus, the coolant gets better between tool and material. Effect The grinding wheel is well rinsed, wheel loading does not occur. Therefore, burns and off-center facets are reduced. 2. Better heat dissipation: Diamond grains are better cooled. Effect Grinding wheel is prevented from damage longer tool life. -

20 3. Better handling of glass particles Effect: Glass particles deposit faster, the grinding solution is cleaner 4. Better anti-redeposition power Effect: Transport of glass particles to the settling tank is faster.

21 5. Increased lubricating effect For the grinding wheel, this means: - the grip of the diamond grain into the glass structure is smoother, thus heat generated during the grinding process is reduced and service life of the grinding wheel is extended - less contact pressure of the grinding wheel For the machine, this means: - higher forward feed - - better corrosion protection - - less energy consumption, less energy demand - For the glass, this means: - no disruptions of the glass - - Less surface-roughness of grinding, i.e. acid polishing is easier -
