2007 MORI SEIKI MT4000

This 2007 MORI SEIKI MT4000 is a versatile machine equipped for precision tasks. It features a max cutting diameter of 939.8 mm and a cutting length of 3,048 mm, providing extensive machining capability. The X-axis travel is 1,005.8 mm, complemented by a Y-axis with 11.81” travel, and a Z-axis travel of 3,149.6 mm. The machine includes a substantial 609.6 mm chuck size and a spindle bore of 274.32 mm.

The spindle motor delivers 37.3 kW of power and achieves speeds up to 1,000 RPM. Rapid traverse rates are differential across axes, with 24 m/min for both X and Y, and 20 m/min for Z-axis. For specialized operations, the B-axis spindle motor provides 14.9 kW and operates at milling speeds of 6,000 RPM. It also includes a CAPTO C8 spindle taper and allows for 120 tool positions with B-axis travel ranging from -120 degrees to +105 degrees.

Noteworthy is the completely rebuilt milling spindle in 2023, a $300,000 investment ensuring enhanced operation. Controlled by the MORI SEIKI MSX-502III, this machine harbors a 50 HP turning spindle and a 24”, 4-jaw Bison manual chuck, along with a substantial 10.8" spindle bore.

Additional features include a ROHM SLZ-325 hydraulic steady rest with a capacity between 1.5" and 9.4". It also comprises a long boring bar attachment, needing realignment, and a tailstock. The chip conveyor and CoolJet high-pressure coolant unit (1,000 PSI) further assist in machining processes, supported by the Royal Mist Collector (FX1200). This machine predominantly cuts 4140 steel.

Offering up to 120 tool positions and a 3000mm cutting length, its operations are robust and adept at handling complex tasks. However, during wrap milling, the machine faces challenges and cannot maintain tolerances under .02". Yet, with the C-axis brake engaged, it can achieve .002" tolerance.

The machine's full replacement cost exceeds $1,000,000, but it's presently in plant, under power, and ready for inspection and purchase. A unique opportunity, given its comprehensive rebuild and existing capabilities, this machine stands prepared for immediate incorporation into custom solutions.
