MACHINE TOOL REBUILDING & RETROFITTING

lathe-after lathe-before

OEM QUALITY REBUILD

Marathon Machine Tools developed a CNC rebuilding program that offers OEM quality rebuild work to its customers.

Complete rebuild projects have been performed on Mori Seiki, Mazak, Miyano, Takisawa, Wasino, Warner & Swasey, and Hitachi Seiki CNC lathes to the utmost satisfaction of our customers.

Our popular Mori Seiki retrofit program offers replacement controls for old Fanuc 6T, 10T and 11T CNCs and new digital spindle drives to replace the obsolete Fuji drives. These heavy duty and well engineered Mori Seiki lathes gain new life with new electronics provided by Marathon.

Retrofit solutions for CNC grinders, CNC milling centers and boring mills such as OKK, Gray and Union will be also offered.
