Description

Overview
The Portalo C 4022 CNC gantry vertical machining centre is built for precision machining of large, heavy workpieces. The fixed gantry and movable table layout supports heavy material removal as well as high‑speed finishing of complex dies and moulds. Modular standard equipment enables adaptation to production requirements.

Highlights
  • High table load capacity for heavy workpieces
  • Large machining envelope
  • Rigid fixed gantry construction
  • 24‑station quick‑action tool changer
  • Renishaw probing systems for tool and workpiece


Gantry
  • Extra‑rigid gantry and guide solutions designed for long travels and heavy cutting
  • Combination of linear guides and box ways for long life, higher speeds and sustained rigidity
  • Preloaded ball screws and Siemens servo motors deliver dynamic feed and fast rapid moves on all axes


Main spindle
  • High drive power and broad speed range provide torque reserves required for heavy‑duty cutting


Tool changer
  • Robust 24‑station changer with dual‑arm gripper for flexible, fast tool changes in production


Control
  • Siemens 828D control with intuitive programming and strong service support
  • Siemens Shopmill software included to simplify programming of complex contours


Equipment
  • Large sliding doors for easy access and loading
  • Renishaw systems for tool and workpiece measurement to reduce setup time and scrap
  • Powerful coolant system and chip conveyor for chip removal
  • Automatic central lubrication to simplify maintenance
