Gantry Machining Center FRU

FRU – portal CNC machine by TOS Kuřim

The gantry machining center FRU is designed for machining large and geometrically complex workpieces. Its key feature is the moving gantry, which allows full utilization of the working table while maintaining high rigidity and machining accuracy.

As a result, the machine is suitable for demanding applications in both heavy and precision engineering.

Design and technical concept

The FRU is designed as a gantry machining center with a moving portal and a fixed working table. This configuration ensures uniform load distribution and stable machining conditions when working with large components.

The machine consists of:

• rigid bed
• working table
• portal structure with columns
• crossrail and cross slide
• headstock

The design focuses on:

• high structural rigidity
• minimal deformation under load
• long-term machining accuracy

Moving gantry and working area

The moving gantry travels along the working table, enabling efficient use of the entire table length.

Key advantages:

• full utilization of the working area
• capability to machine large and heavy workpieces
• stable tool guidance across the entire range

This concept is particularly suitable for large-scale component manufacturing.

Spindle head and interchangeable heads

The FRU gantry machining center is equipped with a versatile spindle head system that supports interchangeable spindle heads.

This allows:

• adaptation to specific machining operations
• combination of multiple machining technologies
• increased production flexibility

Automatic exchange of spindle heads and tools reduces downtime and improves productivity.

Performance and machining capability

The FRU is designed for heavy-duty machining with high material removal rates.

Key characteristics:

• high torque output
• stable performance under continuous load
• suitability for both roughing and finishing
