CNC milling-turning center VSL

verticaldouble-columnwith gantry robot

Overview
The VSL CNC double-column vertical turn-mill machining center integrates turning, milling, boring, drilling, tapping, reaming and grinding in a single setup for large and complex workpieces. Designed for industries such as aerospace, automotive, shipbuilding, energy and mould making, the machine emphasizes rigidity and load capacity via its double-column structure and supports long-duration production runs with precision electric spindles and advanced CNC control.

Key Features

• Multi-process machining: Turning, milling, boring, drilling, tapping, reaming and grinding in one setup to reduce handling and setup time.
• High-precision worktable/spindle bearings: Double-row cylindrical roller bearings for radial support and large thrust bearings for axial guidance, ensuring stable, accurate rotation.
• C-axis indexing: Eliminates gear transmission backlash with C-axis positioning accuracy of ±0.001° for high-precision operations.
• Electric spindle milling head: High-torque, low-noise spindles with water cooling to maintain thermal stability during extended cycles.
• Advanced CNC control: Siemens 840DSl (example) for precise interpolation and integration with automatic tool magazines.

Recommended Configurations

• Spindle options: High-speed electric spindle, optional dual-spindle layout, Y-axis driven tool turret.
• Tooling: Servo tool turret with tool compensation and automatic tool magazine options.
• Clamping: Hydraulic, pneumatic, mechanical or magnetic clamping systems.
• Feed & drive: Linear drives, ball screws and servo motors.
• Cooling & lubrication: Internal, external and high-pressure cooling systems available.
• Control systems: Supports FANUC, Siemens, GSK, KND, SYNTEC, Mitsubishi and other high-performance CNC platforms.
• Other options: Robot integration, Renishaw probes (OMP60 workpiece probe, TS27R tool probe), chain-type chip conveyor, oil mist collector.
