A rotating faceplate with a sliding mechanism is mounted on the main spindle, enabling efficient process consolidation.
The "Bore Center" incorporates a rotating cutting plate with a sliding mechanism (U-axis) into the head of the rotating spindle, enabling easier boring operations through tool integration (reduction in the number of tools), reduction in ATC cycles, and correction of the machining diameter using the U-axis compensation function (optional).

Rotating faceplate with a sliding mechanism at the spindle head
U-axis travel amount⋯0～65mm
The rotating faceplate is directly supported by the spindle head via large-diameter, high-rigidity bearings, and a movable balance mechanism is standard equipment within the faceplate. Of course, in addition to boring operations, machining center functions with general tools such as drills and end mills can be used as before.
High-precision machining with a U-axis spindle head capable of high-precision positioning.
U-axis spindle head designed with an emphasis on precision and durability.
The U-axis drive system utilizes two ball screws and a high-precision rack and pinion to achieve high rigidity and precise positioning. The automatically lubricated U-axis slide is equipped with a full-circumference wiper to prevent chip ingress, ensuring a longer lifespan. A positive stopper and locking mechanism at the center of the faceplate ensure reliable origin maintenance, enabling long-term accuracy preservation.
Built-in counterbalance to prevent unbalance during U-axis movement
