Twin Spindle Horizontal CNC Lathe

The Twin Spindle Horizontal CNC Lathe is engineered for precision turned components requiring operations on both ends.

The main spindle completes the first-side machining, after which the sub-spindle automatically takes over the workpiece to finish the opposite end. For suitable parts, this eliminates manual re-clamping, reversing, and secondary setups on separate machines-significantly reducing manual handling, cycle times, and setup error.

Complete Machining in One Process: Machining of both ends within a single automated CNC cycle.
Reduced Manual Handling: Eliminates manual workpiece removal and repositioning between operations.
Improved Concentricity & Alignment: Controlled sub-spindle transfer preserves programmed geometric relationships between both ends.
Multitasking Capabilities: Combines turning, boring, threading, drilling, cross-hole milling, and tapping in one setup.
High-Efficiency Automation: Integrates seamlessly with bar feeders, gantry loaders, and robotic loading systems.
 

 

Stepped Shafts & Drive Pins: OD turning, shoulder grinding prep, and end-face threading in one pass.
Bushings, Sleeves & Rings: Concurrent ID boring, OD profiling, and back-side chamfering.
Hydraulic Fittings & Valve Bodies: Hex turning, multi-thread cutting, and cross-hole drilling with live tooling.
Flanges & Couplings: Heavy facing, bolt-hole circle drilling via C-axis, and back-side counterboring.

 

 

Raw Material Loading: Bar stock or discrete blanks are loaded into the main spindle manually or via bar feeder/robot.
Main Spindle Operations: Performs OD/ID turning, facing, step turning, grooving, external threading, drilling, and chamfering.
Synchronized Workpiece Transfer: The sub-spindle advances, grips the workpiece securely, and accepts transfer from the main spindle.
Sub-Spindle Operations: Executes back-side facing, OD/ID turning, internal threading, end-face drilling, and chamfering.
Part Discharge: Finished parts exit automatically via a parts catcher, conveyor, or robotic loader.
 

 

Main Spindle: Handles heavy primary cutting. Important specs include spindle bore, chuck size, motor power, and maximum RPM.
Sub-Spindle: Synchronizes with the main spindle to hold and machine the opposite end.
Slant Bed Structure: Heavy-duty inclined bed ensures maximum rigidity, thermal stability, and effective chip/coolant evacuation.
Tooling Turret & Drives: Configurable with standard turn/bore stations or driven (live) tool stations for milling and tapping.

CNC Control Systems: Pre-configured with industry-standard controls.

 

 

Turning & Threading: OD/ID turning, contouring, facing, grooving, parting, and single/multi-start threading.
Drilling & Boring: High-precision center drilling, deep-hole drilling, ID boring, and chamfering.
Milling & Tapping (With Live Tooling & C-Axis): Radial/end-face drilling, off-center cross-hole tapping, slotting, keyway milling, and complex surface interpolation.
Off-Center Operations (With Y-Axis): Precise multi-axis milling and off-center drilling without re-setup.

 

 

Structural Stability: Fine-grain cast iron bed aged to relieve stress, ensuring long-term thermal and mechanical accuracy under heavy cuts.
Transfer Repeatability: Micro-switches and dynamic torque detection verify precise workpiece seating during sub-spindle pickup.
Factory Calibration: 100% evaluated using Renishaw laser interferometers for linear positioning and ball-bar tests for circularity prior to shipment.
