FLEXA

FLEXA - Cylindrical grinding machines

OD/ID grinding

The versatile grinding machines of the FLEXA series are ideal for the flexible processing of different grinding assignments on a single workpiece. The FLEXA is capable of the ultra-precise execution of up to three grinding assignments with minimal retooling time. Whether internal or external grinding and even thread grinding, its modular design makes this conventional, robust grinding machine ideal for small and medium-sized production runs.

FIRE PROTECTION AND LTA AIR FILTERS: In case of an fire, the machine interior is automatically hermetically sealed, suffocating a fire before it has a chance to spread. If required, extinguishers (CO² or water mist systems) and exhaust air purification systems can be additionally installed. A competent partner for fire protection and filtration solution solutions is LTA Lufttechnik GmbH, which also belongs to the JUNKER Group and which researches, develops and produces filtration systems for industrial air purification.
