The Retrofit Center Grinding Machine
The ZS 251 makes your lathe even more capable: as a tailor-made retrofit solution, it is individually adapted to your existing machine by Henninger and integrates seamlessly into your production environment. This allows you to efficiently add center grinding capabilities to your lathe without investing in an additional machine, maximizing flexibility and making optimal use of existing resources.
Roundness Independent of the Base Machine
Roundness accuracy is generated by the grinding unit itself and is therefore independent of the accuracy of the base machine.
As with all solutions from Henninger GmbH & Co. KG, quality and precision are the highest priorities for the compact ZS 251. Benefit from proven Henninger precision as an intelligent retrofit solution for your lathe – compatible with machines from all manufacturers and optimally tailored to your requirements.
