The XD-2SP46Y-AT Parallel Dual Spindle Built-in Robot is a flagship customized turning center from Xindai CNC, a leading China-based manufacturer of CNC machining equipment. Designed for high-efficiency and high-precision composite processing, this machine integrates advanced dual spindle technology, a rigid servo power turret, and a built-in robot—making it an ideal choice for manufacturers seeking to eliminate secondary clamping, reduce production time, and ensure consistent part quality.
As part of Xindai CNC’s Dual Spindles with Integrated Robot product line, the XD-2SP46Y-AT addresses the core needs of modern manufacturing: automation, precision, and versatility. It supports one-time clamping to complete all or most machining processes (turning, milling, drilling, etc.) for complex parts, leveraging features like dual Y-axis, dual C-axis, and high-speed motorized spindles to deliver superior performance across industries requiring tight tolerances.
The XD-2SP46Y-AT’s dual motorized spindle design is the backbone of its efficiency, combining high rotational speed with stable rigidity for uninterrupted processing.
First spindle: Features an A2-5 spindle nose, a maximum speed of 4000 r/min, a through-hole diameter of Φ56 mm, and a bar diameter capacity of Φ45 mm. It supports a maximum turning diameter of Φ320 mm and a maximum cutting length of 250 mm.
Second spindle: Equipped with an A2-4 spindle nose, matching the first spindle’s maximum speed of 4000 r/min and through-hole diameter of Φ56 mm, with a bar diameter capacity of Φ35 mm. Its maximum turning diameter is also Φ320 mm, and maximum cutting length is 250 mm.
Belt-driven transmission: Ensures smooth power delivery, low vibration, and extended spindle lifespan—critical for maintaining precision during long production runs.
The main and auxiliary spindles support high-speed rotational docking, allowing workpieces to be transferred between spindles without stopping. This eliminates the need for secondary clamping, reducing setup time by up to 30% (compared to single-spindle lathes) and minimizing part deformation caused by repeated clamping.
To complement its spindle performance, the XD-2SP46Y-AT adopts an integrated BMT 12-station servo power tool tower—a key component for supporting multi-process composite machining.
12-station capacity: Accommodates a wide range of tools (turning tools, milling cutters, drills, taps) for versatile processing, eliminating the need for manual tool changes.
High rigidity: The BMT (Built-in Motor Turret) design enhances structural stability, reducing tool runout and ensuring consistent machining accuracy even during heavy-duty milling.
Fast tool change speed: Servo-driven tool changes minimize non-cutting time, boosting overall production efficiency—ideal for high-volume manufacturing.
The turret supports standard 20×20 mm tool holders and Φ20 mm boring tool holders, compatible with most industry-standard cutting tools. This flexibility allows manufacturers to adapt the machine to diverse part requirements without investing in specialized tooling.
The XD-2SP46Y-AT uses high-rigidity roller linear guides, paired with precise servo motors, to ensure tight control over axis movements—critical for achieving micron-level precision.
X-axis travel: 195 mm (first spindle) / 225 mm (second spindle)
Z-axis travel: 345 mm (first spindle) / 295 mm (second spindle)
Y-axis travel: ±50 mm (dual Y-axis, supporting off-center machining)
Fast movement speed: 18 m/min across all axes, reducing idle time between machining steps.
The machine delivers a ±0.004 mm repeat positioning accuracy, ensuring consistent part quality even across large production batches. Dual C-axis functionality further enhances precision for contouring, threading, and angular machining tasks.
The built-in robot is a defining feature of the XD-2SP46Y-AT, enabling end-to-end automation of loading, unloading, and workpiece transfer.
Reduced labor dependency: Eliminates manual handling of parts, lowering the risk of human error and improving workplace safety.
24/7 unattended operation: Compatible with lights-out manufacturing, maximizing machine utilization and production output.
Seamless integration: The robot is calibrated to work in sync with the dual spindles and tool turret, ensuring smooth workflow transitions without bottlenecks.
The XD-2SP46Y-AT’s combination of precision, speed, and automation makes it suitable for a wide range of industries and part types, particularly those requiring complex, high-precision machining.
Processes: Machining of engine components (valves, pistons), transmission parts (gears, shafts), and braking system components.
Why it fits: The machine’s high speed and dual spindle design meet the automotive industry’s demand for high-volume, consistent production—with ±0.004 mm accuracy ensuring parts meet strict OEM standards.
Processes: Machining of lightweight alloy parts (aluminum, titanium) for aircraft engines, landing gear, and avionics.
Why it fits: The rigid structure and motorized spindles handle tough aerospace materials, while one-time clamping reduces part deformation (critical for safety-critical components).
Processes: Production of stainless steel or titanium parts (surgical instruments, implant components, valve housings).
Why it fits: The machine’s high precision and contamination-resistant design comply with medical industry regulations, ensuring parts meet biocompatibility and dimensional requirements.
Processes: Machining of connectors, terminals, and sensor housings (often small, complex parts with tight tolerances).
Why it fits: The dual Y-axis and compact footprint make it ideal for small-part production, while the integrated robot supports high-volume output for electronics assembly lines.
Examples: Shafts with multiple diameters, threaded components, and parts requiring both turning and milling.
Advantage: One-time clamping completes front and back machining via spindle docking, eliminating alignment errors from secondary setups.
Examples: Automotive drive shafts, medical catheters (metal cores), and electrical motor shafts.
Advantage: The stable Z-axis travel (up to 345 mm) and low vibration design prevent part bending during machining.
Examples: Gear blanks, pulley wheels, and hydraulic valves.
Advantage: Dual spindles ensure symmetrical machining, with consistent speed and accuracy across both sides of the part.
The XD-2SP46Y-AT supports a maximum turning diameter of Φ320 mm for both the first and second spindles. The maximum cutting length is 250 mm for both spindles, making it suitable for medium-sized rotational parts.
Three key features drive precision: (1) High-rigidity roller linear guides reduce axis movement error; (2) Dual C-axis functionality enables precise angular positioning; (3) A repeat positioning accuracy of ±0.004 mm ensures consistent results across batches.
Yes. The BMT 12-station servo power tool tower provides high torque and rigidity, supporting heavy-duty milling of materials like steel and titanium. The tool tower’s servo drive also ensures stable cutting forces, preventing tool deflection.
It is versatile for both. For small batches, the machine’s quick setup (via intuitive CNC controls) reduces changeover time. For high-volume runs, the integrated robot enables 24/7 unattended operation—maximizing efficiency for large orders.
Yes. Xindai CNC offers customized integration services to match the robot with factory-wide automation systems (conveyors, vision inspection, or ERP software). This ensures the XD-2SP46Y-AT fits seamlessly into existing production lines.
Xindai CNC provides comprehensive training, covering CNC programming (compatible with standard G-code), robot operation, and maintenance. The machine’s user-friendly HMI (human-machine interface) also simplifies day-to-day operation for operators with basic CNC experience.
The machine’s dimensions are 2300×2000×2200 mm (L×W×H), and its net weight is approximately 4000 KG. These specifications should be considered for factory layout and installation planning.
