Double Column Bridge Machine Frame
Details
Featuring a fixed gantry structure (dual columns + fixed crossbeam), the machine ensures exceptional geometric stability. The spindle system (Y/Z axes) remains stationary relative to the foundation, minimizing vibration and thermal deformation during high-speed or heavy-duty cutting. This design guarantees long-term machining accuracy and superior damping capacity for large, heavy components.

Description

Core Technical Features (Moving-Table Structure)

Fixed Gantry & High Static Rigidity

 

Featuring a fixed gantry structure (dual columns + fixed crossbeam), the machine ensures exceptional geometric stability. The spindle system (Y/Z axes) remains stationary relative to the foundation, minimizing vibration and thermal deformation during high-speed or heavy-duty cutting. This design guarantees long-term machining accuracy and superior damping capacity for large, heavy components.

High Efficiency & Reduced Inertia

 

The worktable performs X-axis linear movement, while the spindle remains static. This separation eliminates the inertia errors caused by moving the massive gantry structure, enabling continuous, high-efficiency material removal. It excels in both high-speed milling for aluminum parts and high-torque roughing for hardened steel molds.

Ideal for Heavy-Cutting & Five-Sided Machining

 

Equipped with powerful spindles and compatible with various multi-axis heads (e.g., right-angle, universal), the machine efficiently performs five-sided machining in a single setup. Its fixed column design provides optimal support for deep cavity drilling and large-profile machining.

Z-axis counterbalance system

 

The Z-axis of the machine is equipped with a counterbalance system which can effectively offset the weight of the Z-axis itself, as well as that of the spindle and tools.

 

Customization Options

The double column bridge machine series offers the following customization options:

Taller Column

 

Increases the vertical machining space to accommodate extra-high workpieces, expanding the application range for tall components.

Extended Z-Axis Travel

 

Z-axis travel extended from 800 mm to 1000 mm

Z-axis travel extended from 1000 mm to 1250 mm

These variants provide deeper machining capabilities, critical for deep cavity molds and high-profile parts.

Square Ram Upgrade

 

Replaces the standard T-type ram with a square ram. This significantly enhances structural rigidity, improves vibration resistance, and ensures superior precision during heavy cutting.

Gear Head Equipped

 

Integrates a powerful gear-driven head. This option delivers high torque and low-speed stability, making it ideal for deep hole drilling, tapping, and roughing of difficult-to-cut materials like cast iron and alloy steel.

Spindles with Different Speeds

 

Customize spindle speeds to match specific processes:

High-speed spindles (12,000–20,000 rpm) for aluminum, non-ferrous, and high-speed finishing.

Heavy-duty spindles (3,000–6,000 rpm) for high-torque, low-speed roughing and hard part machining.

This flexibility allows the machine to seamlessly switch between high-efficiency machining and heavy-duty cutting
