Long Aluminum Billet Multi‑Saw Cutting Line with PLC Automatic Length Positioning

The complete system includes:

• Buffer and alignment station
• Multi-billet loading mechanism
• Incoming conveyor
• Primary multi-saw cutting unit
• Discharge conveyor
• Length measuring module
• Finished material rack
• Scrap hopper for trimmed ends
• Aluminum chip recycling system
• Hydraulic power station
• PLC-powered electric control system

An overhead crane moves aluminum billets from the casting pit to the buffer alignment table for end face calibration.

• The multi-billet loader picks up and transports multiple workpieces onto the incoming roller track
• Rollers feed billets toward the main saw station; materials get clamped before head trimming starts
• Billets advance to the length measurement module. Once target dimensions are configured, clamping activates to cut off the billet tail
• Trimmed heads and tails fall into scrap containers under gravity. A fan-assisted assembly collects aluminum cutting chips
• Processed billets are conveyed to the output rack for crane handling

The whole workflow runs under PLC control. Operators input all process parameters digitally via the HMI panel. The system integrates fault alerts and safety interlock protection. Both manual and automatic operation modes are selectable.

Reliability basis: steel grades, national & industry standards and key component suppliers are documented for technical reference.
