Generating- and profile-grinding machines LGG 180 / 28

Machine Concept The new generating and proﬁle grinding machine LGG 180/280 is suitable for the processing all gears up to 180/280 mm diameter. In addition, workpieces can be machined to 650 mm length. For special customer needs various machining variants are available. The generating and proﬁle grinding machine combines short grinding times with consistently high quality in high-volume operations. • Higher quality and reliability across the entire lot size • Single-table solution - One clamping ﬁxture, one geometry - For all gears up to 180/280 mm - Shaft length 500 mm (650 mm as L-version)...

Grinding heads Internal grinding heads The LGG machines are suitable for hob grinding and profile grinding. As standard, the machines are equipped with an external grinding head and can be supplemented with an internal grinding head. Process-optimised external and internal grinding heads are available for the LGG. In both external grinding heads, internal spindle balancing systems are employed. High drive power and speeds are great benefits, e.g. when used with new grinding material. Simple and fast replacement of the grinding pin is made possible by means of modern tool clamping. For...
