CNC Turning Machine
Industrial CNC Turning Machine | High-Rigidity Precision Lathe for Contract Manufacturers
Our industrial CNC turning machines are engineered for rigid metal removal and stable dimensional repeatability in continuous production environments. Built on a cast-iron Meehanite bed with finite element analysis (FEA) optimized ribbing, the machine structure dampens high-frequency cutting vibrations.
Designed for precision job shops and high-volume production lines, the platform accommodates manual loading configurations and automated bar feeder or gantry robot integration. Drive systems utilize preloaded C3-class ball screws and linear guideways, securing micro-meter level positioning accuracy across multi-shift operations.

Key Features
High-Rigidity Slanted Bed Design:
The 30 degree integrated slant bed lowers the center of gravity, improves chip evacuation directly into the lower chip conveyor, and minimizes thermal deformation under heavy axial loads.
Modular Automation Interface:
Standardized electrical and pneumatic interfaces on the enclosure flank support immediate integration with bar feeders, gantry loaders, and articulated industrial robots.
Thermal Isolation Spindle Assembly:
Headstock design incorporates cooling fins and thermal symmetry principles to restrict spindle thermal growth to within 0.01 mm during 8-hour continuous heavy cutting.
Rigid Turret Indexing:
Curvic coupling mechanism clamps the turret disc with hydraulic locking force up to 32 kN, maintaining tool tip repeatability of +/- 0.002 mm after 100,000 index cycles.
