Ligang Machine Tool / LGNCL — Precision CNC Lathes & Multi-Tasking Turning Centers
International procurement of high-precision metal-cutting machinery from Zhejiang Ligang Machine Tool Co., Ltd. (LGNCL, China). Featuring QT series slant-bed CNC lathes, multi-tasking turning-milling centers QT55LS with sub-spindle, and automated DST45 turning cells engineered for volume manufacturing from SpareX.
Precision Slant-Bed CNC Lathes QT45 Series
The QT45 slant-bed CNC lathe handles precision turning of chucked components and bar stock. Its horizontal Z-axis guide rail configuration with four runner blocks distributes cutting forces evenly. Every unit comes pre-wired for seamless robotic truss gantry integration.
- Maximum turning diameter 300 mm and length 225 mm with spindle speed to 4500 rpm
- Axis travel X 160 mm and Z 300 mm with rapid traverse rates up to 24 m/min
- Cartridge spindle A2-5 with 6-inch hydraulic chuck and 45 mm through-hole capacity
- P4 precision bearings, servo axis motors, linear guide runners and proximity sensors
Dual-Spindle Turning-Milling Multi-Tasking Centers QT55LS
The QT55LS multi-tasking center enables full front-and-back part processing in a unified cycle without manual re-clamping. Its rigid slant bed dampens dynamic vibrations during heavy-duty turning and milling. Dual synchronized spindles ensure seamless workpiece handoff on the fly.
- Turning diameter up to 380 mm and length 600 mm with Z1-axis travel of 630 mm
- Positioning accuracy plus-minus 0.003 mm and repeatability plus-minus 0.002 mm
- Main spindle A2-6 with 8-inch chuck and opposing sub-spindle A2-5 with 6-inch chuck
- Hydraulic clamping cylinders, C3 ballscrews, optical feedback scales and couplings
Multi-Axis Turning-Milling Centers QT-LM / LMY / LMSY with Y-Axis
The QT-LM and QT-LMY series combine heavy turning capability with an orthogonal Y-axis for multi-tasking operations. The motorized BMT turret performs off-center drilling, rigid tapping, and complex keyway profiling. This consolidated kinematic layout eliminates secondary shop handling.
- Orthogonal Y-axis stroke plus-minus 50 mm for off-center milling and pocketing
- Live tooling turret BMT45/BMT55 delivering milling tool speeds up to 4500 rpm
- High-resolution C-axis spindle contouring with 0.001-degree angular indexing
- Radial live tool holders, axial milling modules, Y-axis ball screws and drives
Slant-Bed Linear Guide CNC Lathes GT80 Series
The GT80 series delivers high-speed finishing and semi-finishing for precision automotive and instrumentation parts. A monolithic slant-bed iron base maintains superior thermal stability under continuous cutting. Heavy-duty linear roller guides reduce friction and slide wear.
- Swing over bed 350 mm and maximum turning length 280 mm with A2-5 spindle nose
- Rapid traverse speeds of 20 m/min along X-axis and 24 m/min along Z-axis
- Bi-directional positioning repeatability along X and Z axes within 0.003 mm
- Class C3 ground ball screws, AC axis servo motors, gib strips and wiper seals
High-Performance Heavy Turning Centers GT150 Series
The GT150 heavy turning center is built for aggressive stock removal on forgings, flanges, and medium-sized workpieces. A reinforced structural base absorbs cutting shock loads during heavy roughing. Milling-equipped variants GT150M and Y-axis GT150MY offer versatile multi-tasking.
- Turning diameter up to 350 mm and length to 500 mm with swing over bed 550 mm
- High-torque spindle motor paired with dual-range electronic speed control
- Hydraulic power chuck 8 or 10 inches with spindle bore diameter of 75 mm
- Heavy-duty spindle bearing packs, directional valves, drive belts and relays
Integrated Automated Turning Production Lines DST45 with Truss Robots
The DST45 automated production cell merges CNC turning modules with an overhead truss gantry manipulator in a compact footprint. An intelligent dual-gripper handles automatic raw blank loading and finished part removal. Multi-machine tandem cells run 24/7 in lights-out manufacturing.
- Integrated multi-axis servo gantry loader mounted directly above the machines
- Automated workpiece turnover station enabling back-end machining operations
- Unmanned processing of parts up to 300 mm diameter and 260 mm length in batch
- Pneumatic gripper jaws, robotic guide rails, safety light curtains and sensors
Machining Capabilities and Equipment Range of Ligang Machine Tool
Ligang Machine Tool engineers precision slant-bed CNC lathes and multi-tasking turning-milling centers for high-tolerance batch manufacturing.
Produced by Zhejiang Ligang Machine Tool Co., Ltd., these machine tools serve demanding applications in automotive manufacturing, hydraulic fittings, aerospace sub-assemblies, and industrial hardware.
The product lineup features heavy-duty slant beds with superior dynamic damping, precision linear roller guide rails, and balanced A2-5 and A2-6 spindle units operating at up to 4500 rpm.
Advanced multi-tasking variants incorporate synchronized sub-spindles, full C-axis contouring, and orthogonal Y-axis live-tool turrets.
Engineering Selection of CNC Lathes and Turnkey Truss Automation Cells
The DST45 combined turning lines integrate truss gantry manipulators to deliver automated turning cells for unmanned manufacturing. Equipment configuration begins with evaluating component envelope dimensions, metallurgical hardness, geometric tolerance bands, and desired production takt times.
For complex workpieces requiring front and rear machining, dual-spindle QT55LS multi-tasking centers eliminate manual repositioning and maintain strict concentricity.
SpareX provides comprehensive manufacturing feasibility reviews, production cycle simulations, and tailored tooling package selection.
