Premium model boasting the best cutting perfomance in it's class

Horizontal spindle machining centers

FH550SX / FH630SX-i / FH800SX-i

Unrivaled rigid platform allowing the spindle to achieve it’s full performance

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 possesses superior vibration damping characteristics. This 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.

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.

The spindle taper cap replacement method takes ease of maintenance into consideration.
The separate spindle taper makes individual cap replacement possible as it is integrated with the taper, even in the event of taper damage caused by accidental interference.
