| Description |
| This machine is being offered in recontrolled and recertified condition. We can also offer it with a full rebuild (Call for details). All recontrolled and 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 the test cutting are documented for your viewing. |
| During the recontrol process this the entire electrical cabinet will be replaced. A new CNC of your choice will be installed, along with new servo motors, feedback devices, and motor and feedback cabling. A easy to use conversational program will be provided to allow for easy operator data entry and storage. |
