LIEBHERR 5 AXIS GEAR HOB, MODEL LC-255, FANUC 18i-MA, REBUILT/RETROFIT 2006,

Inventory ID: 10343
Specifications:

 This machine was recontrolled by Machine Tool Builders in 2006 with a Fanuc 18i-MA CNC and Fanuc Alpha series digital drives and motors.  An entire new electrical cabinet was installed along with all new equipment inside the electrical cabinet.  All support, service, parts and training are still available through Machine Tool Builders.  Machine upgrades, software additions or other machine modifications or tooling that might be required are also available through Machine Tool Builders.  The software in the machine is fully conversational based so the simple question and answer format allows quick and easy programming of all spur and helical gears within the machine size and DP rating.

The machine is being offered in "as-is" condition.  We can also offer it as recertified or with a full rebuild (call for details).  All recertified machines are fully cleaned.  All moving slides, spindles, and parts handling systems are inspected for problems.  Any gibs or adjustable backlash systems are adjusted to the best possible settings.  All hydraulic, coolant, lubrication and pneumatic systems are checked for proper functionality and leaks.  All filters are replaced.  All worn hoses, broken cables, connectors, buttons, lamps and wires are replaced.  All guarding is installed and checked.  All machine cycles are tested.  Parts are cut to verify the machine capability.  Charts from test cutting are documented for your viewing

AS-IS condition means the machine will be cleaned and checked for operational capability without test cutting taking place.  All cycles and all features will be verified for functionality.
