DANOBAT Launches the ESTARTA-400, a New Concept of a Centreless Grinding Machine
DANOBAT celebrates 60 years of experience in manufacturing grinding machines with the presentation of the ESTARTA-400, a innovative machine with cutting-edge technology, one of the most rigid centreless grinding machines available on the market to meet the most demanding requirements in high-speed manufacturing.
DANOBAT’s objective is geared towards higher productivity for its clients by decreasing cycle times. To achieve this objective, DANOBAT has designed a grinding machine specifically for high speed production (120 meters per second with CBN abrasives), paying special attention to rigidity and vibration damping, two critical factors in demanding grinding processes.
Market requirements are well known by the company; for many years now we have been working in close collaboration with our customers to provide turnkey solutions. This provides DANOBAT with the benefit of knowing the real needs of the targeted sectors that are met with the new grinder: the automotive, hydraulic or aerospace sectors, among others. As a matter of fact, the firm counts among its grinding machine users some of the leading companies in these sectors such as Ford, Renault, TRW, Mahle, Rexroth,Lufthansa and Airbus, among others.
The international launch of the new ESTARTA-400, which is already available on the market, will take place at the AMB, regarded as the leading industry event among the world’s top 5 exhibitions in the metallurgical sector, to be held from 16 to 20 September in the German city of Stuttgart.
In the words of Harvi Chana, Grinding Division Director of DANOBAT, the new ESTARTA-400 “has been designed from the first pencil stroke for work at high speed and optimised to make it one of the most rigid grinding machines available on the market”. “This will enable our customers to significantly improve cycle times and thus maximise their production output”, he says.
To achieve these unique features, DANOBAT has incorporated cutting-edge technology in order to obtain a practically unequalled rigidity on the market. In addition to optimising the design in the above respect, a motor-driven head with additional support eliminating overhang is used as well as a new damping system for guiding of the slides. A patent application has been submitted for both developments.
Equally important is the roller guideway systemof the machine, providing two important advantages: a greater movement sensitivity and a more ecofriendly grinder, as the hydraulic component becomes superfluous, requiring a lower energy consumption and reduced maintenance.
The combination of these technologies allows maximum sensitivity with optimal damping, which yields in maximum accuracy, even in the most severe working conditions.
