Product Overview

The aluminum billet gang sawing machine is designed for multi-bar cutting of aluminum alloy long bars. The production line integrates bar alignment, multi-bar loading, roller conveying, head cutting, sizing, discharge, and aluminum chip collection into one equipment configuration.

The machine is specified for aluminum alloy bars with diameters from Ø80 to Ø254 mm. Its main sawing motor is 45 kW, while the total line power is 90 kW. The horizontal circular saw uses a Ø900 mm alloy saw blade, with a specified blade speed of 1400 rpm.

Five-Bar Simultaneous Sawing

Multi-Bar Cutting Configuration

A key specification of this multi-bar aluminum saw is its capacity to saw five Ø120 mm aluminum bars at one time. The documented continuous sawing speed is ≤60 seconds per five bars, based on aluminum bars measuring Ø120 * 6000 mm. This parameter defines the stated cutting cycle for the specified material size and operating condition.

The feeding conveyor has a speed of 25 m/min, with adjustable conveying speed. The maximum pre-cut bar length is 13,000 mm, providing the specified operating range for long-bar feeding.

Saw Blade and Cutting Parameters

The saw blade specification is Φ900 * Φ50 * 72T alloy blade. The document also specifies a kerf width of saw blade thickness plus 1 mm and a cut surface roughness of ≤30 μm.

Automatic Feeding and Discharge

Long-Bar Loading

The loading section consists of a buffer and alignment table, multi-bar loading and unloading machine, and feeding conveyor. The loading platform is 6.5 m long, while the manipulator performs lifting, lowering, and left-right transfer of the aluminum bars.

After head cutting, the discharge mechanism transfers the bars toward the sizing section. The cut heads and tails are collected separately, while aluminum chips are automatically conveyed by a fan into a collection container.

Sizing and Control System

The sizing length is specified as 4500–6000 mm, with a stated length accuracy of ±2 mm. The system uses a Mitsubishi PLC and a 7-inch Weinview HMI, supporting manual and automatic operation, fault alarms, and automatic interlock protection.
