FAQs of Liebherr L300 Gear Hobbing Machine:

Q: How does the Liebherr L300 Gear Hobbing Machine achieve high precision in gear cutting?

A: The machine utilizes a robust mechanical gear and lever drive system supplemented by mechanical/electro-mechanical controls. This ensures accurate synchronization between the table and hob, enabling precise and repeatable gear cutting operations, especially for gear diameters up to 300 mm and modules up to 6.

Q: What types of gears and workpiece sizes can be processed with this machine?

A: The L300 Gear Hobbing Machine is capable of hobbing gears with diameters up to 300 mm and workpiece lengths of up to 650 mm. It supports a maximum module of 6, making it suitable for a wide range of industrial gears and precise component manufacturing.

Q: When is it advisable to use the included coolant system during operation?

A: The coolant system should be used during all hobbing and cutting processes to minimize heat buildup, maintain optimal cutting temperatures, and extend the lifespan of both the hob and the workpiece. This results in smoother surfaces and more accurate gear profiles.

Q: Where can the Liebherr L300 Gear Hobbing Machine be installed for optimal use?

A: The machine is best installed in manufacturing environments such as workshops or industrial production floors where precise gear cutting is demanded. Its robust, heavy-duty construction and compact dimensions (2000mm x 1600mm x 2100mm) make it adaptable to various facility layouts.

Q: What is the operational process for hobbing gears with this machine?

A: The process starts by securely mounting the workpiece on the table and installing the appropriate hob. Machine settingssuch as table speed, hob speed, and slide positionare adjusted according to the gear specifications. The workpiece and hob then rotate in sync, enabling the hob to cut the gear teeth precisely.

Q: How does the machine benefit gear manufacturers and industrial operations?

A: This machine offers reliable, high-precision gear cutting capability, improving production efficiency and product quality. Its heavy-duty design, large workpiece capacity, and user-friendly manual or electro-mechanical controls make it a valued asset for exporters, manufacturers, and suppliers who require consistent gear output in India.
