Designed for large lot-size machining of big aluminum wheels or similar parts, the You Ji YV-600E2T Vertical Turning Center (VTC) is described as a compact, high-precision, heavy-duty machine suitable as a stand-alone machining cell or integrated with other machines to form a complete flexible manufacturing system, according to a Feb. 11 news release issued by Absolute Machine Tools Inc., Lorain, Ohio.

Among the highlights of the VTC:

• A maximum swing of 33.4" and a maximum turning diameter of 29.5".
• Rigid vertical column and base are Meehanite castings, heavily ribbed for reduced thermal distortion and vibration dampening.
• The X and Z axes employ roller-type linear guideways.
• Specially designed sliding covers inside the machine are said to virtually eliminate chip problems.
• All ways are completely enclosed, while a forced lubrication system ensures high-precision production.
• The high-speed way systems enable rapid traverse rates of 787 in./min.
• Precision "Class 3" ballscrews are driven directly by the servo motors, eliminating belts or gears for more exact machining.
• The spindle construction is of a heavy-duty design incorporating double roller bearings as well as 45-degree angular contact thrust bearings. The 100-HP high-torque spindle motor drives the spindle via belts, providing plenty of power for heavy-duty machining and the high speeds necessary for fine finishing.
• Twin 6-position hydraulic vertical hex turrets are mounted on the rams with tough bolt-on tooling.
