You Ji Machine Industrial Company, Ltd. CY-550H

The CY-550H+APC Vertical Turning Center is a compact, high precision, heavy duty machine with an integrated pallet changer for uninterrupted production. The rigid vertical column and base are meehanite castings, heavily ribbed for reduced thermal distortion and vibration dampening. It is designed for turning of medium sized workpieces. The X and Z axis linear guideways are completely enclosed and a forced lubrication system assures high precision. The high speed linear way system enables rapid traverse rates of 787 inches per minute. Box ways are available as a no charge option. The precision class 3 ballscrews are driven directly by the servo motors, eliminating belts or gears for high precision. The spindles are constructed using 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 endure high centrifugal loads and big spindle loads. The 30 HP high torque Fanuc spindle motor provides more torque at a lower RPM than a Fanuc 50HP single wound motor and delivers power for heavy duty machining and high speed for fine finishing. For heavy cutting an optional ZF planetary gearbox is available for high cutting torque on large diameter The 8 position (10 position optional) hydraulic turret provides for .5 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. 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.
