Overview
The LabCenter 260 CNC is a compact, mobile vertical CNC machining center designed for CNC training and small-series production. It reproduces the core functions of larger production machines in a reduced footprint. The continuously variable main spindle runs up to 5000 rpm and the SIEMENS 808D Advance control provides an intuitive operator interface for learning and standard production tasks. ISO 20 spindle taper, automatic tool clamping and a 4-station pick-up tool changer enable practical, hands-on operation.

• Preloaded ball screws on all axes for accurate motion
• Main spindle speeds up to 5000 rpm (ISO 20)
• 4-station pick-up tool changer for quick tool swaps
• Mobile base with integrated storage for tools and accessories
