FUTURE MANUFACTURING
Climate-neutral production increases precision
FRANK RINGAT
Sustainability , resource conservation and efficiency are driving themes in mechanical and plant engineering . Far-reaching energy-efficient measures can make it possible to produce in a climate-neutral manner and at the same time to significantly increase manufacturing precision .

The milling cell with robot loading ensures high accuracy and tight tolerances .
Hermann Diebold , owner of Helmut Diebold GmbH & Co . Goldring tool factory from Jungingen , says : “ We make our products as precise as possible and not just as precise as the standard requires .” The longevity of the manufactured products is particularly important to him , because this “ pays for sustainability .” Therefore , only minimal tolerances are allowed during production .
In order to improve accuracy during production , the company started their Gauge product line for measuring tool holders and spindles in 2002 and invested in a fully air-conditioned production hall in 2006 . With this , the company improved its level of precision and today produces tool holders and spindle components with a tolerance of less than one micron . This is proven by the measurements in Diebold ’ s measuring room , which corresponds to quality class 2 and in which there is always a constant temperature of 21 degrees Celsius .
How to avoid cutting problems
A full air conditioned factory entails higher fixed costs which makes the products more expensive . But investing in high accuraxy products pays off for the end user . According to Hermann Diebold , there are significantly cheaper products on the market . However , these often do not meet the requirements of the DIN / ISO standards for accuracy . That ' s why the company from Jungingen offers its users the checking of their tool holders used as a service . The test is necessary when customers have machining problems and need to find the cause . The result of these measurements is amazing , because on average 30 percent of the tool holders used do not meet the accuracies required by the standards . Even 70 percent nonstandard tools are not uncommon in the measurements . If this occurs , users are forced to purchase new tool holders . This
