Pursue even higher productivity through automation
A variety of automation equipment such as bar feeders, workpiece unloaders, and Auto parts catcher are optionally available, enabling long-term automatic operation.
Bar feeder and workpiece unloader (QRX-50MS SG, QRX-50MSY SG）
While the main spindle is processing, the finished product on the second spindle is removed from the machine, allowing for continuous automatic operation without impairing the machine’s cycle time. The specification of the work unloader can be chosen between a hand type and a bucket type.
1: Bar feeder 2: Workpiece unloader
Auto parts catcher
The bucket attached to the lower turret is used to transport the finished products from the first spindle and the second spindle (for MSY), as well as the bar remnants.
12 station drum turret (24 position) as standard
The 12 station drum turret (24 position) is designed for minimum interference. The tool holder utilizes the BMT45 standard. The holder can be mounted 180° reversibly.
CNC system MAZATROL SmoothG
Large touch screen for intuitive operation
Highly efficient machining with 2 turret dedicated display and support functions
The display divided into two columns makes it easy to confirm the operation of each turret. The EIA/ISO programming screen displays the waiting command positions side by side, enabling intuitive and easy program editing.
2 split display EIA/ISO programming screen
Various program check functions
Virtual Machining
Accurate simulation under the same operating environment as the machine enables us to check the machining shape and interference in advance. This enables highly productive operations from the first production piece.
Safety Shield
Even when axes are moved manually during setup work, the 3D model on the NC screen checks for interference and alerts the operator to prevent machine interference.
Inter-grid single block operation
When one turret completes a process, all turrets in operation stop simultaneously, even if the end of the block differs for each turret. This inter-grid single block operation ensures the synchronization between turrets, preventing interference and increasing downtime caused by program misalignment.
With Inter-grid single block operation
A: Turret A
B: Turret B
1: When turret B X-axis feed reaches ▲, turret A also stops.
2: When turret A X-axis feed reaches ▲, turret B also stops.
▲: Operation stop
Without Inter-grid single block operation
A: Turret A
B: Turret B
▲: Operation stop
Override synchronized operation
Override, which allows adjustment of program processing time, is reflected not only in the operating time of the turrets but also in the standby time, thus enabling program operation without disrupting synchronization between turrets. This allows for high-accuracy interference checks.
A: Turret A
B: Turret B
1: Dwell (standby time)
2: Supporting Functions
3: No program misalignment
A: Turret A
B: Turret B
1: Dwell (standby time) No change in time
2: Supporting Functions
3: Program misalignment occurred
Manual pulse handle operation
The machining program can be operated at any speed by turning the handwheel of the CNC system by hand. The approach position and points where interference is likely to occur can be carefully checked.
