Twin Spindle Y Axis Turning Center

The Twin Spindle Y-Axis Turning Center is engineered for high-precision components requiring both rotational turning and off-center secondary operations. By combining main spindle machining, automated sub-spindle part transfer, Y-axis travel, and live tooling, this machine replaces multiple traditional setups with one continuous production cycle.

Reduced Secondary Setups: Machine both front and rear ends of complex parts without manual repositioning.
Higher Geometric Precision: Completing turning and milling in one clamping eliminates cumulative tolerance errors caused by multiple fixture setups.
Lower Labor & Capital Investment: Replace separate lathes and milling machines with a single compact footprint and one operator.
Automated Production Ready: Seamlessly integrates with automatic bar feeders, chip conveyors, and parts catchers for uninterrupted batch runs.

Main Spindle Operations: Raw stock is clamped in the main spindle for initial facing, turning, boring, grooving, and threading.
Y-Axis & Live Tooling Operations: Driven tools perform off-center drilling, keyway slotting, face milling, and radial tapping.
Precision Part Transfer: Sub-spindle synchronizes speed, approaches, securely grips the workpiece, and takes over under exact CNC control.
Sub-Spindle Operations: Sub-spindle performs rear-side facing, turning, internal boring, chamfering, and back-drilling/milling.
Part Unloading: Finished component is parted off and safely unloaded manually or via an automatic parts catcher.

The Y-axis introduces perpendicular movement to the spindle centerline, enabling complex multi-task machining:
Off-Center Drilling & Tapping: Drill and tap holes positioned away from the central axis.
Cross Drilling: Machine radial side holes directly during the primary cycle.
Flats & Slot Milling: Mill parallel flats, hexes, and keyway slots on shafts and fittings.
Profile Milling: Execute complex contours and curved slots using coordinated C/Y/Z motion.

Monoblock Slant Bed: Heavy-duty cast iron structure absorbs vibration, ensures thermal stability, and allows optimal chip flow.
Dual Precision Spindles: High-rigidity spindle cartridges backed by premium NSK/FAG angular contact bearings for heavy cutting and fine finishes.
Servo Power Turret: Rapid index time with high-torque driven tooling stations for fast cycle execution.
Precision Motion Control: THK/HIWIN linear motion guideways and ground ball screws ensure long-term positional repeatability.
Automated Lubrication: Programmed metered oil delivery protects linear guides and ball screws from premature wear.

Bar Feeder Integration: Enables automated continuous feeding for high-volume shaft or bar stock production.
Parts Catcher & Unloader: Safely catches finished parts and routes them outside the enclosure without manual intervention.
Hinged Belt Chip Conveyor: Efficiently removes long or curly chips during continuous operation.
Tool Presetter / Measurement: Renishaw / Marposs tool probe for rapid automatic tool offset setting and breakage detection.

Every machine undergoes strict inspection before shipment to guarantee factory-floor readiness:
Dynamic Laser Alignment: Pitch error and axis accuracy calibrated via Renishaw laser interferometers.
Alignment Standards: Main-spindle to sub-spindle coaxial alignment checked within <= 0.005 mm.
Runout & Geometric Checks: Spindle runout and bed squareness measured according to ISO standards.
Pre-Shipment Trial Run: Full cycle machining test on customer drawing samples with dimensional CMM inspection report provided before dispatch.
