Super Heavyweight VTL Tackles Heavy Duty Cutting


Lorain, Ohio, July 14, 2006 – The VTL-1600ATC-II Vertical Turning Center from You Ji is exceptionally strong and extremely powerful, making it ideal for heavy duty, large parts turning. Absolute Machine Tools, Inc. offers this super heavyweight machine, which tips the scales at an impressive 85,800 lb. The machine is engineered for manufacturers requiring tremendously rigid, strong, and stable machines, such as those in the aircraft and power generation industries.

The VTL-1600ATC-II boasts heavily ribbed Meehanite castings that minimize thermal distortion and dampen vibration. Both X and Z axes are supported by oversized, hardened and ground box ways that deliver outstanding stability and rigidity. The VTL’s symmetrical design and exceedingly large column supply additional rigidity and stiffness. Complementing these is a 9” x 9” square ram (Z axis) that is also extremely rigid – even when extended to its full 47” stroke.

In addition to the massive column, ram, and box ways, the VTL-1600ATC-II incorporates large diameter, preloaded Class 3 double nut ballscrews in X and Z. The machine’s highly reliable servo motors directly drive the ballscrews, eliminating belts or gears for further precision. All machines come with a matched Fanuc control, servo, and spindle system that ensures system reliability, precision, and long-term machining performance.

The VTC’s heavy duty spindle is built to withstand the toughest cutting conditions. It incorporates a beefy 23” diameter precision cross roller bearing and NN type roller bearings that easily bear high axial and radial loads. In addition, the spindle’s 60 HP Fanuc high torque motor (100 HP optional) is coupled with a two-speed ZF gear box. The combination generates tremendous spindle/table torque – 12,900 ft-lb – providing plenty of power for heavy duty machining.

The umbrella-style ATC stores twelve #50 taper tools and provides shortest route tool selection. The machine is also equipped with a standard conveyor that washes away chips and coolant for maximum machine productivity.

Options include a contouring C axis with live tools for drilling and contouring. The C axis can be positioned to 0.001 degree for drilling and tapping. It can also be used as a full contouring axis. The live tooling used for the C-axis is backed by a 15 HP (30 HP optional), two-speed gear box drive system that delivers up to 2,400 RPM. Other custom options include larger capacity tool magazines (up to 60 tools), auto tool presetter, and much more.

The You Ji VTL-1600ATC-II is designed for stand alone applications or easy integration into production lines. The machine can be customized to meet virtually any production requirement.
