The first successful product produced by the former Blaser+Co AG was Blaha-Glanz, a waterrepellent shoe polish that was sold on the surrounding farms. Willy Blaser laid the foundation for today’s company group in the crisis year 1936. The real upturn in the company’s fortunes began after the war when the customer base expanded to include besides farmers, mechanical workshops, the construction industry, the wood and metal processing industries and the first industrial factories. Today, Blaser Swisslube has its own subsidiaries and agents close to its customers in around 60 countries across the globe and employs a total of 600 employees - 300 of whom are employed in Switzerland.
From metalworking fluid to Liquid Tool
The company continued unabated to develop its expertise in all things to do with metalworking fluids. This involved expanding and refining its research and development facilities to what, today, are the largest of its kind in the industry. With a surface area of around 3,500 m2, 70 chemists, microbiologists and laboratory technicians work on designing and developing coolants of the highest quality and, adopting true continuous improvement principles, analyse metalworking fluid samples from customers around the world. In order to be able to offer customers an effective added value when it comes to machining, the company inaugurated its very own Technology Centre in 2009. “Our Technology Centre is truly state-of the-art and enables us to carry out stringent tests on new metalworking products and system solutions,” explains Marc Blaser, Managing Director, Blaser Swisslube AG. “It also ensures that we are able to work in partnership with customers helping them improve their productivity, economic efficiencies and machining quality by identifying and developing metalworking fluid solutions that are tailored exactly to their needs, which we call a Liquid Tool.”
Doubling of the tool life
In a recent project, Blaser experts in the Technology Centre impressively optimised the tool life. A renowned partner filled the role of international supplier and manufactured aircraft parts from a high-strength titanium alloy. In the ultra-modern Technology Centre in Hasle-Rüegsau, a range of tests were started with the goal of optimising the tool life during pocket machining.
The specialists at Blaser reconstructed the partner’s machining environment and employed the same machining parameters and data using a DMG Mori DMU 65 mono block machining centre, and began comprehensive tests employing trochoidal milling strategies.
Operation: Pocket milling Material: high-strength titanium alloy for aircraft construction Machine type: DMU 65 monoblock (DMG MORI)
Tool: Sandvik 2P342-1200-CMA 1740 – End mill with a diameter of 12 mm
Cut parameters: Vc 80 m/min, fz 0.075 mm, ae 0.9 mm, ap 19 mm
Coolant pressure: 75 bar
The tests compared machining performance (tool wear) when using a conventional metalworking fluid against an optimal metalworking fluid specifically adapted to the partner’s needs. The series of width of wear tests were conducted up to 0.30 mm.
The results were excellent. Using the optimally adapted coolant from Blaser Swisslube, 11 instead of just five pockets could be milled until the wear on the tool forced the processing to be stopped. The result achieved was confirmed in various series of tests, and corresponds to a doubling of the tool life. ☐
