Serial Number 25502
Year of manufacture 1976
Year of remanufacture 2006

This machine was fully rebuilt and converted to CNC in 2006. We recently acquired the machine and are now offering it for sale. All our rebuilt machines are fully disassembled and cleaned. All parts were inspected for wear and are either replaced or repaired as required. All the way surfaces were refinished by hand scraping and grinding, all anti-friction coatings are checked and replaced if required. All bearings were checked and replaced as required, all seals were replaced. All new hydraulic, pneumatic and lubrication system components like valves, pressure regulators, sensors pumps etc. were installed. All new electrical equipment like limit switches, push buttons, junction boxes, flexible conduit etc were installed. The entire electrical cabinet was replaced along with all the equipment inside. A new CNC was installed into the cabinet. Prior to reassembly all the individual machine components were painted separately and allowed to dry. This allows us to insure there is good paint coverage under all items bolted to the machine, and that new items installed were not being painted over in the process.

During the rebuilding process this mechanical machine was converted to a full CNC machine by modifications to the drive train systems. MTB engineers designed the most effective method of axis drive for each machine by keeping the drive train as short as is feasible given the machine constraints. Axes motors were connected with anti-backlash shrink disc couplings where ever possible and in some cases belt drives and/or additional anti-backlash gear boxes were required to adapt the motor to the load properly.
