New YOU JI VTL 800 ATC | Vertical Boring Mills (incld VTL)

Description

The You Ji VTL-800ATC 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 / large size workpieces.

The X axis and Z axis box guideways on the large square ram are completely enclosed and a forced lubrication system assures high precision. The rigid box way system enables fast rapid traverse rates of up to 472 inches per minute. The precision class 3 ballscrews are driven directly by the servo motors, eliminating belts or gears for high precision. The large square ram (7.1”x7.1”), made from cast steel, is extremely rigid even when extended the full 31.5”. This machine has a fixed rail for maximum rigidity when machining shorter parts.

The spindle construction is a heavy duty design incorporating an 18” O.D. / 13” I.D. Timken Cross Roller bearing for heavy axial and radial loads and high precision. The spindle also is protected from coolant contamination. Tremendous table torque is developed by the 30 HP Fanuc P series double wound high torque spindle motor coupled with the 2 speed ZF gear box. The double wound spindle motor provides more torque at a lower RPM than a 50HP single wound motor. 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 6,293 ft./lbs., reaching full power in low gear at only 25 RPM and providing the power for heavy duty machining.

The ATC stores 12 tools with a #50 taper tool attachment. This umbrella style ATC provides shortest route tool selection and is completely shielded from chips and coolant. Larger capacity magazines are optionally available. 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 standalone applications or is easily integrated into a production line.
