The YV-600A by You Ji is a flexible vertical turning center that is especially useful for the aerospace, oil field and other industries for turning medium sized workpieces. Absolute Machine Tools Inc. offers this compact system, which features a six-station hex turret that is designed to ensure little to no tool interference. The machine is designed for stand-alone applications or easy integration into production lines. It comes in mirror-image right and left-hand versions, allowing shops to place machines side by side in a work cell. Such an arrangement boosts productivity by giving shops two spindles in essentially the same space as one horizontal turning center. This also lets one operator run both machines.

The 34,000-lb VTC’s rigid vertical column and base are Meehanite castings, heavily ribbed for reduced thermal distortion and vibration dampening.

The VTC has the precision and repeatability to deliver even the tightest tolerances. Its X- and Z-axis linear guideways are completely enclosed, and a forced lubrication system ensures high precision. The high-speed linear way system enables rapid traverse rates of 787 ipm. Boxways are also available. The VTC’s precision Class 3 ballscrews are driven directly by the servomotors, eliminating belts or gears for high precision.

The spindle construction is a heavy-duty design incorporating high precision double roller bearings and 45-degree angular contact thrust bearings. The spindle also is protected from coolant contamination. The NN-type spindle bearings are used to withstand high centrifugal loads and spindle loads. The 30-hp, high torque Fanuc “P” series double-wound spindle motor coupled with the two-speed ZF gearbox provides the same power output as a Fanuc 50-hp single with the two-speed gear box. The “P” series motor delivers power for heavy-duty machining and high speed for fine finishing. The spindle produces almost 3,000 foot-pounds of cutting torque for heavy cutting.
