| Description |
|
This machine is being fully rebuilt. All rebuilt machines are fully disassembled and cleaned. All parts are inspected for wear and are either replaced or repaired as required. All the way surfaces are refinished either by hand scraping or grinding, all anti-friction coatings are checked and replaced if required. All bearings are checked and replaced as required, all seals are replaced. All new hydraulic, pneumatic and lubrication system components like valves, pressure regulators, sensors pumps etc. are replaced. All electrical equipment like limit switches, push buttons, junction boxes, flexible conduit etc are replaced. The entire electrical cabinet is replaced along with all the equipment inside. A new CNC is installed into the cabinet. Prior to reassembly all the individual machine components are 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 being installed are not being painted over in the process. You can specify the paint color of your choice.

During the rebuilding process this mechanical machine will be converted to a full CNC machine by modifications to the drive train systems. MTB engineers will design 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 are connected with anti-backlash shrink disc couplings where ever possible and in some cases belt drives and/or additional anti-backlash gear boxes may be required to adapt the motor to the load properly.

| The aforementioned description and listing of specifications and accessory equipment is correct and accurate to the best of our knowledge. However, it should not be considered binding in any regard, as we reserve the right to change and/or alter same without prior notice. Consequently the buyer is responsible for confirming same, upon physical inspection and inventory of the machine(s) and all related accessory equipment. |
