Machine tool reconditioning
HELLWIG performs the reconditioning and/or modernization of your machine tools and special machines.
Our range of services also includes CE consultation and implementation of the minimum requirements in accordance with the Betriebssicherheitsverordnung [German Ordinance on Industrial Safety and Health].
Machines that HELLWIG reconditions attain at least the precision of the original new machine. (Depending on the machine type, often it is even possible to achieve precision that surpasses that of the new machine). Reduced downtimes are an important “side-effect.”
Spare part manufacturing: Sometimes spare parts for mechanical, electrical or electronic components are not available. No problem: working from drawings or samples, HELLWIG manufactures mechanical parts that are not (or that are no longer) available at the required quality and precision. For electrical/electronic parts we search for a replacement or suggest obtainable alternatives.
Machine and system modernization
From the application- and customer-specific point of view, modernized machines are often more efficient and almost always more economical and substantially more cost-efficient than a comparable investment in new equipment.
Modernization comprises measures for increasing performance, improving quality, reducing wear and raising the operator convenience levels, and particularly the installation of CNC controllers and conversion of machines intended for special jobs, often on the basis of existing equipment. HELLWIG replaces the machine tool controller or upgrades it, as required.
Controller retrofit or replacement on machine tools
A (new) machine’s controller does not always fulfill the user’s expectations. HELLWIG offers advice on the selection of the best-suited controller independent of the given manufacturer.
HELLWIG technicians plan and implement the complete replacement of CNC controllers on machine tools. Controllers from all established brands, such as Siemens, Heidenhain, Fidia, Num, Bosch, etc., are used. Where required, HELLWIG replaces all electrical equipment, from the drives to the measuring systems to the switch cabinet.
