Herkules Sets Standards in
Efficiency and Technology
Steel products are a key material in modern industrial societies and are used in almost all industrial branches due to their versatility, strength and cost-effectiveness. In particular, surface-finished steel from the cold rolling mill plays a core role, predestining it for demanding applications. Surface-finished cold-rolled steel is therefore used in the automotive industry, construction, mechanical engineering and the household appliance and packaging industries, among others.
This is why the Vietnamese manufacturer DONG A - PHU MY CO, Ltd. decided to purchase a Herkules roll grinding machine. The WS 450 S x 5,000 CNC Monolith™ is equipped with state-ofthe- art measuring and testing technology so that defects can be detected and rectified reliably, quickly and on the fly during the grinding process. „Our C-frame measuring device provides highly accurate measurements of the roll, ensuring perfect roundness along the entire length of the barrel at all times,“ explains Tobias Wurm. „Our Eddy Current measurement system immediately detects surface cracks and structural changes in the roll.“ In addition to the patented Monolith™ technology, the machine is also equipped with combination steady rests for work and back-up rolls as well as softloaders – two roll types, one solution.
„The combination steady rest can accommodate both roll types,“ says Tobias Wurm. „It optimally compensates for deflections and vibrations and impresses with its high rigidity and precise adjustability. In addition, the changeover times from one roll type to another are simplified and extremely minimized.When inserting the rolls, the softloader supports the barrel with a defined, „soft“ force to prevent damage to the rolls and the steady rests.“
In this way, the customer can significantly enhance overall performance while ensuring that all end product requirements are consistently met. “Our machine plays a key role within the customer’s machinery fleet. The level of performance and precision it delivers would otherwise be almost impossible to achieve,” says Tobias Wurm. “Our state-of-the-art technology also minimizes roll wear and reduces grinding wheel consumption, significantly extending roll service life and lowering operating costs.“
