YV-600A Vertical Turning Center by You Ji: Flexible and Powerful VTC


The YV-600A by You Ji is a highly flexible vertical turning center that is ideal for the aerospace, oil field, and other industries turning medium sized workpieces. Absolute Machine Tools, Inc. offers this compact system, which features a six-station hex turret that ensures little to no tool interference. The VTC 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.

Solid machine construction is key to the YV-600A’s performance. The 34,000-lb VTC’s rigid vertical column and base are Meehanite castings, heavily ribbed for reduced thermal distortion and vibration dampening.

The You Ji YV-600A 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. Box ways are also available. The VTC’s precision class 3 ballscrews are driven directly by the servo motors, 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 gear box 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 nearly 3,000 ft-lb of cutting torque for heavy cutting.

The six position hydraulic hex turret provides for 0.8 second index time and shortest route tool selection. A live tool turret is available as an option. Chip control is excellent as chips and coolant wash directly into the standard chip conveyor. An optional chip wash system forces any chips from the machining area into the conveyor.

Other standard features include a three jaw, 24-in. hydraulic chuck with cylinder and one set of soft jaws and six boring and turning tool holders. A Fanuc OiT-C CNC with manual guide conversational programming is also standard.
