IN STOCK, UPGRADE COMPLETED, UNDER POWER AND READY TO GO! - BUT STILL MODIFIABLE TO MEET YOUR REQUIREMENTS!
This LC-502 hobber was treated to a light duty lifetime of making mostly plastic, aluminum and bronze fine pitch gears. It is mechanically in like new condition. We installed a new Fanuc 0iM-F Plus CNC and all new Fanuc HVi Alpha servos and spindle drive. It comes equipped with a special coolant/ filtering system to capture the non ferrous particles as well as ferrous materials. It includes 2 each 32mm Diameter Hob Arbors. The machine also has a servo controlled tailstock up/down function and power hob clamping.
This machine is being offered with a full recontrol using a Fanuc 0i-MF Plus and in a fully re-certified condition. All MTB re-certified 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 the test cutting are documented for your viewing.
