Surface Grinding machine LGB 1270 RN
DOUBLE COLUMN SURFACE GRINDING MACHINE FOR MASS PRODUCTION
The portal structure of the machine (mobile table, fixed bed, portal and traverse) enables increased stability and rigidity which are enhanced by controlled thermal stabilization.
The “X”, “Y” and “Z” axis are equipped with SCHNEEBERGER roller guides and HEIDENHAIN absolute linear encoders which ensure high accuracy in the positioning of the axes. The software, developed by the LGB team, supported by the SIEMENS “Touch screen” enables quick start and intuitive use. The combination of each elements of the machine provides high performance in your simple and complex grinding operations.
This new “RN” range was developed in close cooperation with our clients and our partners in order to meet machining requirements in the field of tool making (mold design, matrices and models), production of parts for aviation and car industry as well as for high precision mechanics products.
