1998 Miltronics Partner 1 Vertical Machining Center with Centurion V (5) controls. This machine was used lightly the last several years to machine aluminum and Renfoam. In using the machine for the last seven years, we experienced no problems until recently when the Milltronics 24VDC power supply failed and was replaced. This vertical machining center is equipped with SEM dc servos for the axes and a 240VAC 14hp spindle with a dedicated drive. The tolerance that this machine is capable of holding  approximately.002"-.003", which was sufficient for the machining we performed in the past. It still has the original 12" CRT monitor, but the original controls were upgraded to utilize an intel processor card. There are two damaged pins on the z-axis servo amp which never appeared to present a problem because the machine still performed as normal. This machine was running when it was taken out of service and was powered by 240VAC 3ph. No tooling or spare parts are included in this auction, only the complete machine: frame, controls, motors, spindle, tool changer, coolant tank & pump and hoses. The machine is complete and has not been dismantled or had any modifications done to it. Other than the Z-axis locking up, all other drives, spindle, controls and cooling system are functional. For communication, this machine has a DB25/RS232 COM port and an embedded ethernet port on the processor card. It comes with the original manuals for machine parts, electrical diagrams, and the centurion V programming manuals (in duplicate).

Currently, the machine is not working due to a component failure in the z-axis. The Servo AMP that drives the z-axis’ DC Servo-Motor has two header pins that have overheated and are no longer attached to the board. Either this board could be repaired or replaced with a similar unit. These two pins belong the one of the three windings in the DC Servo-Motor. We would advise replacing the Servo-Amp in addition to having the DC Servo-Motor inspected and repaired. The costs for this are approximately $2000. This cost was based on information received from vendors who normally sell parts or make repairs. After having these two items repaired or replaced, full functionality could be restored.

It is currently wrapped in plastic and awaiting pick-up.

Buyer is resposible for shipping and rigging arrangements. The approximate weight of the machine is 5500lbs dry weight. It is located in the Palestine, TX area.
