New YOU JI YV-800A | Vertical Boring Mills (incld VTL)

Description

The You Ji YV800A Vertical Turning Center is a compact, high precision, heavy duty machine. The rigid vertical column and base are meehanite castings, heavily ribbed for reduced thermal distortion and vibration dampening. It can be used for medium and large size workpieces. The X and Z axis are available in your choice box ways with Turcite-B or heavy duty linear guideways. The ways are completely enclosed and a forced lubrication system assures high precision. The high speed way system enables rapid traverse rates of 787 inches per minute. The 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 a high precision 18” O.D. / 13” I.D. Timken Cross Roller bearing and NN type roller bearings to endure high axial and radial loads and accommodate chuck sizes up to 40”diameter. The spindle also is protected from coolant contamination. Tremendous table torque is developed by the 30 HP Fanuc “P” type high torque spindle motor coupled with the 2 speed ZF gear box. The combination of the high torque Fanuc motor with the ZF gearbox generates more torque at a lower RPM than a standard 50HP motor with a gear box. The spindle is then driven by a class 1 ring and pinion gear which provides a further gear reduction and torque multiplication. Spindle / table torque is an amazing 7,125 ft./lbs., providing the power for heavy duty machining.

The 6 position hydraulic hex turret provides for 1 second index time and shortest route tool selection. Chip control is excellent as chips and coolant wash directly into the standard chip conveyor. A standard chip wash system forces any chips from the machining area into the conveyor. This versatile VTL is designed for stand alone applications or is easily integrated into a production line. A right / left spindle configuration is available for placement in a work cell.
