Description

Synchronous Four-Head Corner Combining

The Aluminum Profile CNC 4-head Corner Combining Machine completes corner key crimping on all four corners simultaneously, ensuring balanced force, consistent joint quality, and significantly higher production efficiency.

CNC Automatic Size Positioning

Using an industrial control computer, the machine automatically detects and positions different window frame sizes, allowing quick changeover between various aluminum window dimensions without manual recalibration.

Intelligent Torque Monitoring System

Real-time torque monitoring enables automatic pre-tightening at each corner, ensuring uniform crimping pressure and improving the mechanical strength and long-term stability of aluminum window joints.

High-Precision Hydraulic Crimping Control

With powerful hydraulic output and precise stroke control, the machine guarantees stable corner forming, minimal profile deformation, and excellent diagonal and gap accuracy.

Advantages &Features

FAQ

What types of aluminum windows can this machine assemble?

The Aluminum Profile CNC 4-head Corner Combining Machine is suitable for most aluminum door and window profiles using corner key crimping structures.

How does the machine ensure four corners are evenly tightened?

The machine uses torque monitoring to automatically control pre-tightening force on all four corners, ensuring uniform pressure and consistent joint quality.

Is the hydraulic crimping force strong enough for thick thermal break aluminum profiles?

Absolutely. The centralized hydraulic station provides immense, continuous pressure designed specifically to permanently lock heavy-duty corner cleats inside thick thermal break extrusions and commercial curtain wall systems without crushing the outer surfaces.

How does the machine prevent gaps from forming at the 45-degree mitered corners?

It features an intelligent torque monitoring system. Before the hydraulic knives strike, the machine gently but firmly pushes all four corners inwards simultaneously, pre-tightening the frame to guarantee a flawless, gap-free joint before the final crimp.

Do the operators need to manually move the crimping heads when changing window sizes?

No. The machine is fully CNC-driven. The operator simply inputs the new dimensions into the industrial PC, and the precision servo motors automatically drive the heavy crimping heads to the exact required position in seconds.

What is the maximum window size this 4-head combining machine can process?

It easily accommodates a wide range of frame sizes, with a standard maximum working area of 1800x3000mm. The CNC system automatically adjusts the heads to process anything from small bathroom windows to massive commercial balcony doors.
