Large workpiece grinding machine LCS 600 - 1200

for workpiecesCNC

The new LCS Series 3 provides a machine system for the hard-fine machining of gears, which is characterized by its outstanding efficiency and versatility: generating or profile grinding with dressable or electro-plated CBN tools. Gear grinding with dressable worms or discs has been a successful and well established technology for many years. Today, with the use of sintered corundum tools, it has reached a remarkable performance level. With the LCS series, Liebherr enables the user to use both technologies without limitation, unlocking completely new possibilities in particular generating grinding the sorts of larger gears used in the wind power industry, for example. The grinding heads, with their proven design principle, provide motor spindle speeds up to 12,000rpm. Their high degree of thermal stability is essential for achieving unparalleled quality. Active tool holding on both ends guarantees excellent tool rigidity. This allows for feed rates up to 10m/min and a cutting speed of 100m/s. With the two-station ringloader, workpieces up to 800mm in diameter can be automatically loaded and unloaded. Storage systems are available for unmanned operation of the machine. Double dresser Double dresser for dressing grinding worms or form grinding discs with two independent, frequency-controlled dressing spindles. Functional principle: Single flank dressing Dressing of the tooth tip via rotating radius roller Pressure angle correction via C5 axis Advantages: Easy to use universally With radius control, the sharp-edged transition from the tooth flank into the area of the tooth root can be avoided Longer radius roller life compared to dressing plate
