Double Spindle CNC Lathes

The Double Spindle CNC Lathes are engineered for high-efficiency, multi-tasking machining in continuous batch production environments. By integrating primary and counter spindles within a single rigid structural system, these lathes execute complete front-and-back machining in a single setup—eliminating secondary workpiece handling, reducing transfer time, and maximizing production consistency across multi-shift operations.

Core Advantages & Engineering Proof

Synchronized Done-in-One Machining
How it Works: Automated workpiece transfer from main to counter spindle eliminates manual re-clamping.

The Result: Cuts cycle times by 35% - 50% and virtually eliminates fixture alignment stacking errors.

High-Rigidity Meehanite Cast Iron Base
How it Works: One-piece Meehanite cast iron frame, stabilized via two-stage thermal stress-relief tempering to minimize structural vibration.

The Result: Maintains ±0.003 mm repeatability under standard finish turning, with high dynamic rigidity sustained during heavy cutting.

Tier-1 Global Component Integration
How it Works: Built with genuine FANUC/Siemens controls, NSK/SKF bearings, and THK linear guideways.

The Result: Proven MTBF exceeds 10,000 hours, minimizing downtime and overseas warranty liabilities.

Complete Machining Capabilities

Our double spindle platform is designed to handle multi-tasking processes that typically require multiple machines:

Front-and-Back Machining: Complete primary turning/milling on the main spindle, followed by automated handover to the counter spindle for back-end finishing.

Complex Cross-Operations: Supports simultaneous or sequential cross-drilling, tapping, and off-center milling when equipped with a live tool turret and Y-axis.

High-Volume Continuous Runs: Fully compatible with continuous bar feeding, enabling unmanned machining during night shifts.

Tailored Configurations & Machining Capacity

Modular Spindles: Customizable chuck sizes and programmable stroke lengths tailored to your specific workpiece dimensions.

Advanced Tooling: Supports live turrets, Y-axis, and sub-spindle C-axis for single-setup milling, drilling, and tapping.

Automation Ready: Pre-configured layouts for seamless integration with bar feeders and overhead gantry loaders.

Target Applications

Automotive Parts: High-concentricity gear shafts, input/output shafts, and pinion gears requiring dual-spindle synchronized handover without surface marking.

Hydraulic Industry: Multi-featured valve spools, hydraulic cylinders, and high-pressure fluid connectors.

Precision Hardware: Aerospace fasteners and medical components requiring complex front-and-back machining in a single cycle.

Compliance & Global Standards

To ensure seamless integration into overseas factory floors, machine tools are built compliant with international industrial frameworks:

CE Certification: Fully compliant with European Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU.

Electrical Standardization: Built according to NFPA 79 / UL standards for North American industrial electrical safety.

Engineering Deliverables

Every machine tool ships with a complete engineering documentation package:

Pre-shipment Factory Acceptance Test (FAT) Run-off Video & Log.

Complete Foundation & Layout Drawings (CAD/PDF).

FANUC/Siemens Ladder Diagrams & Electrical Schematics.

FAQ

Q: How is the spindle alignment and accuracy verified before shipping?

A: Every machine undergoes dynamic linear calibration and geometric alignment verification via Renishaw® laser interferometers, followed by a 48-hour continuous dry-cycle run. The original inspection charts are signed off by our QA lead and included in the shipping documents.

Q: How do you handle overseas after-sales support and replacement parts?

A: CNC controllers are fully covered by FANUC/Siemens global warranty networks. For mechanical components, we utilize standard tier-1 global brands (like NSK or THK) to ensure easy localized sourcing. Critical spares can also ship via DHL/FedEx within 24 hours from our central stock, backed by 24/7 remote engineering support.

Q: Is the lathe compatible with my existing third-party bar feeders or robotics?

A: Yes. The electrical cabinet is pre-wired with standard I/O bar feeder interfaces (e.g., LNS/Fedek protocols). For custom factory automation like gantry loaders or robotic arm integration, our engineering team can pre-configure the handshake signals based on your part drawings prior to shipment.

Q: What is the standard production lead time?

A: Standard configurations ship within 30–45 days due to our in-house casting and machining infrastructure. Custom automation configurations or specialized tooling layouts require up to 60 days.
