The You Ji VTL-1600ATC Vertical Turning Center is a large, high precision, heavy duty machine. The rigid vertical column and base are meehanite castings, heavily ribbed for reduced thermal distortion and vibration dampening. It is built for heavy duty turning of large size workpieces. The machine features a symmetrical design with a very large column. The X and Z axes are a box way design with Turcite B applied to mating surfaces and hand scraped for perfect fit and alignment. The ways are completely enclosed and a forced lubrication system assures high precision. This rigid system enables heavy duty machining and high precision. The Z axis is a large 9" square ram (10" square on ATC-II) made from cast steel that is extremely rigid even when extended the full 35.4" (47.2" on ATC-II). The precision class 3 ballscrews are driven directly by the servo motors, eliminating belts or gears for high precision. The cross rail is moveable on box ways and is hydraulically clamped for rigidity and precision. The cross rail's movement is programmable and is moveable in 200mm increments. The rail is clamped in position by positive locking pins to insure the cross rail is always level. The spindle construction is a heavy duty design incorporating a high precision 30" O.D. / 23" I.D. Timken Cross Roller bearing to endure high axial and radial loads. The spindle also is protected from coolant contamination by a double labyrinth seal. Tremendous table torque is developed by the 60 HP Fanuc high torque spindle motor coupled with the 2 speed ZF gear box. The 2 speed ZF gearbox transmits power through another intermediate gearbox and the table 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 12,900 ft./lbs., providing the power for heavy duty machining. A 100HP table drive motor is optional for brute force turning. The ATC stores 12 tools with a #50 taper (#60 taper opt.) tool attachment. This umbrella style ATC provides shortest route tool selection and is completely shielded from chips and coolant. 16, 32, 60, and larger tool magazines are optional. Chip control is excellent as chips and coolant wash directly into the standard chip conveyor. This versatile VTL is designed for stand alone applications or is easily integrated into a production line.
