Update your equipment without purchasing new machines – HELLER Retrofits help to keep your existing machines up to date. The continued use of the existing infrastructure and peripheral equipment makes retrofits a cost-effective alternative. Our specialists overhaul the existing equipment tailored to your needs and wishes to achieve improvements in productivity and precision. In addition to using HELLER original spare parts we ensure comprehensive quality assurance with a full warranty on the complete scope of services.
The solid mechanical construction of HELLER machines guarantees longterm precision far beyond the depreciation period. After a service life of many operating hours, a machine tool's production performance and precision no longer satisfy current requirements. Partly this is due to unavoidable wear and tear but also to the changing requirements of today's machining tasks. We can make your HELLER machine fighting fit for new tasks. With a solution that is more cost-effective than buying a new machine.
The original HELLER Retrofit factory overhaul restores your existing machines to state-of-the-art condition. Our knowledge and quality awareness as a designer and manufacturer provide the perfect foundation for this. A factory overhaul pays dividends for older machines from the following series:
Not only will we restore the performance of your machine, we will also increase productivity by up to 20%. With a control upgrade and numerous retrofit options and software updates, the performance of your machine will enjoy an additional boost.
As always with our service solutions, we aim to offer you the optimal retrofit solution for your specific requirements. That is why we offer you two different packages for the overhaul of your used machine:
Irrespective of the package you choose, your machine will be overhauled to the high standards you have come to expect from us. The acceptance criteria are the same as for a new machine.
All components undergo a testing process. Fault-free components are re-used, defective ones are professionally reconditioned and will only be replaced by new parts on an individual basis and after consulting you. This approach ensures that the costs of your retrofit are proportionate to the planned remaining useful life.
A control retrofit is already included as the basis of the machine retrofit. With HELLER Quality you are guaranteed highest quality standards and the same test and acceptance criteria applied for HELLER Premium.
On request, we seize the opportunity of the HELLER Premium retrofit to install all available technology upgrades released since the original delivery of your machine. That means we will optimise your machine in a way that enables you to achieve a measurable increase in productivity compared to the original delivery condition, allowing you to reduce your per-piece costs. We leave nothing to chance. That is why all wear parts are replaced with new components and a control retrofit is included in the standard scope of the retrofit. This includes installation of a new state-of-the-art control cabinet and fluidics module.
The test and acceptance criteria are the same as for a new machine. Depending on the application, the HELLER Premium machine retrofit can help you achieve an increase in productivity of up to 20%.
Retrofit of the control comprises complete rewiring, installation of a new control panel and optionally a new control cabinet housing (CE-compliant and EMC-compatible), new Sinumerik 840D sl CNC control, new Sinamics S120 drive modules, new operating panels (main operator panel and operator panel at the tool loading station) and new decentralised I/O modules. On request, new AC motors in all drive axes, a new main spindle motor and further additional retrofits can be offered.
HELLER uni-Pro 90 is replaced by Sinumerik 8400sl. Up to 15 % increase in productivity.
As part of the control retrofit, the existing control cabinet will be fully replaced (drive amplifier, CNC control) and rewired.
