The net weight of ≈4000 KG ensures stability during high-speed operation, preventing machine vibration that could affect machining accuracy.
The Dual Spindle Docking Truss Manipulator is tailored to meet the precision and efficiency needs of multiple high-demand industries, where consistent quality and fast production cycles are critical.
Automotive Parts Manufacturing: In the automotive industry, this manipulator is ideal for processing core components such as engine crankshafts, gear blanks, brake caliper pins, and transmission shafts. These parts require tight tolerances (often ±0.005 mm or higher) and high-volume production—needs that the dual-spindle design addresses by eliminating secondary clamping and reducing cycle time. For example, it can complete turning, milling, and drilling of a gear blank in one setup, cutting production time by up to 30% compared to single-spindle lathes.
Aerospace & Defense: The aerospace sector demands ultra-precise components (e.g., aircraft engine parts, hydraulic fittings, and sensor housings) made from high-strength materials like titanium or stainless steel. The Dual Spindle Docking Truss Manipulator’s high rigidity and repeat positioning accuracy (±0.004 mm) ensure it can machine these materials without compromising precision, even during long production runs.
Electronics & Medical Equipment: For small, delicate parts such as electronic connector pins, sensor housings, and medical device components (e.g., surgical instrument shafts), the manipulator’s dual-spindle docking and gentle clamping prevent workpiece deformation. Its ability to handle small bar stock (down to Φ35 mm for the second spindle) makes it suitable for these miniaturized parts.
Hydraulic & Pneumatic Components: Manufacturers of hydraulic valves, pneumatic cylinders, and fluid connectors rely on the manipulator’s ability to machine complex internal and external features (e.g., threaded ports, sealing grooves) in one setup. The BMT 12-station turret supports specialized tools for these tasks, ensuring consistent quality across batches.
Beyond industry applications, the Dual Spindle Docking Truss Manipulator excels in specific workpiece scenarios that require efficiency and precision:
One-Clamp Complete Processing: For workpieces that need both front and back machining (e.g., double-ended shafts, cylindrical parts with holes on both ends), the dual-spindle docking function allows bidirectional clamping. This means the main spindle processes the front of the workpiece, then docks with the sub-spindle to transfer it for back-side processing—all without removing the workpiece from the machine. This eliminates clamping errors and reduces handling time.
Complex Turn-Mill Composite Tasks: Parts requiring both turning and milling operations (e.g., shafts with keyways, flanged parts with drilled holes) benefit from the manipulator’s dual Y-axis and dual C-axis. For example, it can turn the outer diameter of a shaft, then use the Y-axis to mill a keyway and the C-axis to drill a radial hole—all in one setup, avoiding the need to transfer the part to a separate milling machine.
High-Volume Precision Production: For businesses producing 1,000+ units of a part per day (e.g., automotive fasteners, electronic pins), the manipulator’s high-speed spindles (4000 r/min) and fast tool changes reduce cycle time per part. Its automated design also minimizes human error, ensuring consistent quality even during long shifts.
Unlike standard dual-spindle lathes that often require stopping rotation for workpiece transfer, the Dual Spindle Docking Truss Manipulator supports high-speed docking (while spindles rotate at up to 4000 r/min). This is made possible by its precise dual-axis linkage control system and high-rigidity roller linear guides, which maintain alignment between the main and sub-spindles. The result is faster cycle times and no loss of precision during transfer—critical for high-volume production.
Yes, the manipulator is equipped with dual Y-axis (±50 mm effective travel) for both the main and sub-spindles. The Y-axis enables radial movement of the tool, which is essential for complex operations like off-center drilling, milling of slots or grooves, and machining of asymmetric features. For example, when processing a shaft with a radial hole, the Y-axis positions the drill precisely at the desired distance from the shaft’s center, eliminating the need for custom jigs or secondary operations.
The manipulator offers a repeat positioning accuracy of ±0.004 mm, a metric that measures how consistently the machine can return to a specific position after multiple cycles. This level of precision is critical for industries like aerospace and medical device manufacturing, where even tiny deviations (e.g., 0.01 mm) can render parts non-functional. The accuracy is achieved through high-precision servo motors, rigid linear guides, and advanced CNC control software that compensates for thermal expansion and mechanical wear.
