Twin Spindle Turning Center

The Twin Spindle Turning Center is designed for turned components requiring machining on both ends. The main spindle performs the first machining operations, and the sub-spindle takes over the workpiece inside the machine for second-side machining. This eliminates separate manual setups, reduces cycle time by up to 40%, and keeps both operations within a single CNC process. It is suitable for shafts, bushings, sleeves, hydraulic fittings, hubs, couplings, flanges, and other precision components requiring multi-process machining.

Automotive & Transportation: High-volume drive components, sensor bodies, and hydraulic fittings.
Hydraulics & Fluid Power: Precision valve bodies, fluid adapters, and manifold sleeves.
Industrial Machinery: Precision spacers, rollers, drive pins, and motor shafting.
Aerospace & Medical: High-tolerance connectors, cylindrical enclosures, and titanium/stainless fittings.
Contract Precision Machine Shops: Job shops seeking lower labor overhead and versatile two-sided production capacity.

Main Spindle Clamping: Raw bar stock or blank is secured in the main spindle.
First-Side Machining: The servo turret performs primary turning, facing, boring, grooving, or threading.
Part Transfer: The sub-spindle moves axially to sync with main spindle rotation and clamps the workpiece.
Spindle Handover: Main spindle unclamps or cutoff occurs, handing the workpiece smoothly to the sub-spindle.
Second-Side Machining: The sub-spindle holds the part while remaining secondary features are machined.
Part Unloading: The completed part is safely ejected to an integrated parts catcher or automation arm.
 

High-Speed Servo Turret: Rapid index times reduce non-cutting cycle time.
C-Axis Contouring: Full 360° spindle indexing enables precise angular positioning for pitch-circle hole drilling, slotting, and keyway milling.
Driven Live Tooling: High-torque driven tool stations turn your lathe into a turn-mill center, completing off-center secondary operations in the same setup.
Y-Axis Capability: Provides perpendicular linear movement relative to the spindle center, allowing off-axis cross-drilling, multi-flute milling, and complex keyway features.
 

Shafts & Pins: Stepped drive shafts, splined pins, and guide rods requiring two-sided alignment.
Bushings & Sleeves: Precision sleeves needing concentric ID boring and OD turning on both ends.
Hydraulic & Pneumatic Fittings: Valve spools, adapters, hose connectors, and fluid blocks with multi-step threads.
Hubs & Couplings: Rotary couplings and power transmission flanges.
Connectors & Housings: Cylindrical electrical housings with complex face/radial holes.

Tailor options to match specific production bottlenecks:
Larger Spindle Bore: For continuous processing of oversized bar stock.
C-Axis + Live Tooling: Solves secondary cross-drilling and face-milling requirements.
Y-Axis Motion: Essential for complex off-center features and precise flat milling.
Automatic Bar Feeder: Enables unattended 24/7 continuous bar stock feeding.
Parts Catcher & Unloader: Safely transfers finished components out of the enclosure without scratching.
Gantry / Robotic Arm Loading: Ideal for heavy individual forged blanks where bar stock feeding is not applicable.

Every machine undergoes strict quality verification prior to dispatch:
Laser interferometer positioning and repeatability accuracy checks
Spindle dynamic balance testing and full-rpm run-in testing
Automated spindle transfer sequence and hydraulic pressure stability checks
Full functional testing of CNC controls, safety interlocks, and coolant delivery
Trial Machining: Optional test cuts performed on customer part drawings prior to shipment upon request.
