Optimal for machining large parts for any industry
The performance of the machining center depends on the Spindle.
• The spindle serves as a core of the machining center.
• JTEKT sticks to the spindle, which is important because it is located nearest the cutting point, to keep stable cutting accuracy.
Adopting a spindle cartridge replacement system with maintainability in mind
• Even in the rare chance that a failure does occur, a replacement spindle cartridge that has been checked at JTEKT for operation and quality can be installed in its place, keeping restoration time down to a minimum.
A Rigid cylindrical roller slide able to withstand high speed, high acceleration travel while still maintaining rigidity is adopted
• Compared to the ball guide, the cylindrical roller slide features less elastic deformation against loads and smaller displacement caused by load variation, as well as possesses superior vibration damping characteristics.
• The feature makes it possible to position quickly with smaller orientation changes upon sudden acceleration or stoppages contributing to a higher level of production efficiency.
• Because of JTEKT’s assembling technology which allows for strict mounting face accuracies, the rigid cylindrical roller slide offers the best rapid feed rate and acceleration in it’s class.
