Maxflow wins approval in practical testing
High-quality standard products and innovative individual solutions are trademarks of the comprehensive range of products offered by Gühring OHG: As one of the world’s leading suppliers of rotary cutting tools and equippers of new machines, the owner-managed company in Albstadt continuously optimises quality, efficiency and process reliability. This is why, in the special tools area, the cooling lubricant filtration on the grinding machines for spiral grooves is being changed to a filtration system that does not use filter aids. In addition, the systems must be flexibly deployable with oils or emulsions. During a two-year testing phase of all types of equipment available on the market, the Maxflow compact filter system of GKD – Gebr. Kufferath AG demonstrated its winning features. The system combines particle retention all the way to the micro-filtration range and briquetting in a single piece of equipment.
The efficiency of the cooling lubricant in this process is of crucial importance for meeting the stringent customer requirements in regard to surface quality, shape accuracy and tolerances. Thus it is essential that the lubricant be prepared properly. The highly consumptive precoat filters and magnetic separators that Gühring has used until now are to be replaced with a type of equipment that works just as effectively, whether with oil or emulsion, and requires no filter aids. One by one, over the past two years, the company has tested a vacuum belt filter, a paper cartridge filter, a disc filter and the Maxflow filter system. Only the Maxflow CS 1000-504 filter system excelled across the board in the tests. In addition to simple operation and efficient, automated filtration, the integrated briquetting feature and compact design won over the testers. Because the sludge is pressed to pure briquettes with minimal residual moisture, the amount of waste and thus disposal costs fell. Wolfgang Löckel, Head of Plant Engineering at the Gühring parent plant, expressed his satisfaction: “Maxflow is a good and also very compact piece of equipment with the great advantage of producing relatively dry sludge that is already pressed into briquettes.”
