5-AXIS & 5-SIDED MOVING-COLUMN CENTER
Modular reach,
uncompromised precision.
The GRANDER Series is a high-performance moving-column machining centre for efficient machining of medium to large workpieces. Its rigid structure, advanced guideway technology and high-dynamic drives deliver accuracy, productivity and long-term reliability.
With modular X-axis travel from 4,000 mm to 40,000 mm and a broad selection of milling heads, GRANDER supports heavy-duty roughing through high-precision simultaneous 5-axis finishing across aerospace, energy, railway, mould and die, general engineering and heavy-equipment applications.
ENGINEERING DEEP DIVE
Designed to move
with certainty.
High-Rigidity Moving Column Design
The rigid moving-column structure protects geometric accuracy throughout the machining envelope. Dual linear guideways on the X axis pair with a dual helical rack-and-pinion drive, electronically preloaded to eliminate backlash for smooth, responsive motion.
KEY BENEFITS
- Excellent positioning accuracy and contouring capability.
- High feed rates with stable heavy-cutting dynamics.
- Long-term geometric stability across the full X-axis range.
Accessible Y-Axis Travel
Generous Y-axis reach accommodates side-face machining with tools up to 300 mm long without compromising rigidity or accessibility.
One Platform, Two Demands
The architecture combines heavy cutting and precision finishing in a single flexible production platform.
Chain-Type Automatic Tool Changer
The chain-type ATC travels with the moving column, reducing exchange time at every machine position while accommodating long, heavy cutting tools.
KEY BENEFITS
- Reduced non-cutting time and faster tool exchange cycles.
- Reliable continuous production with support for long and heavy tools.
Column-Traveling ATC
Tool changes remain fast and consistent across the entire machining area instead of depending on column position.
Production Continuity
Robust handling and high reliability improve spindle utilization and support unattended production cycles.
Automatic Head Changer
An Automatic Head Change System stores multiple milling heads in a protected magazine and exchanges them without operator intervention. Secure storage prevents contamination at the spindle interface, preserving long-term accuracy.
KEY BENEFITS
- Automatic head exchange increases machining flexibility and utilization.
- Less set-up time and lower labor requirements.
Protected Head Magazine
Each head is securely stored to protect the spindle interface from contamination.
Application Flexibility
Automatically match the appropriate head to each operation, from roughing to simultaneous 5-axis finishing.
