IRM Model 4H6D2S 4-Head Strip Brushing Machine - 4" Width

وصف

The IRM Model 4H6D2S is a purpose-built 4-head strip brushing machine designed for surface preparation applications, particularly pre-bonding cleaning of metal strips and foils where surface contamination removal and oxide layer treatment are critical to bond quality. This machine excels at preparing materials for subsequent bonding, laminating, or coating operations by providing controlled, consistent brushing action across the strip width.

Four brushing heads (two top, two bottom) with 6" diameter brushes ensure thorough surface contact and cleaning action. Each brush head is equipped with individual AMP meters that indicate contact force on the material, allowing operators to monitor and adjust brushing pressure for optimal surface preparation without material damage. The hardened and chromed 6" diameter supporting rolls are height-adjustable to accommodate varying material thicknesses up to 0.125".

Four independent 7.5 HP, 3500 RPM brush motors provide ample power for aggressive surface preparation when needed, while the reversible operation allows for brush sharpening and extended tool life. All brush heads are controlled from a central operating station, streamlining operator workflow and ensuring consistent processing parameters.

The machine accommodates strip widths up to 4" and includes adjustable strip guides throughout the pass line to maintain material positioning and prevent edge damage during brushing. A built-in recoiler with 1,500 lb capacity features a 1.5 HP DC variable-speed motor (0-50 FPM) and 10" air clutch for precise tension control, essential for maintaining strip flatness during surface preparation.

This brushing machine is designed for both inline and offline surface preparation applications. In inline configuration, the precision force monitoring and integrated recoiler enable synchronized processing with bonding mills or coating lines for continuous workflow operations. For offline operations, the machine provides controlled batch processing with consistent parameter control for pre-treating material ahead of subsequent bonding or laminating processes.

The integrated 5" diameter dust collection port allows connection of appropriate filtration systems for material removal and operator safety. This capability is particularly important when brushing creates oxide particles, scale, or other contaminants that must be captured during either inline or offline operation.

This IRM 4H6D2S was removed from active production service in operational condition and is believed to be fully functional based on its operating history. The machine is being offered in as-is condition, allowing buyers to acquire proven surface preparation capability at an attractive price point.

This brushing machine is ideal for pre-bonding cleaning operations, electronics packaging operations, battery foil manufacturers, aerospace surface preparation, and any operation requiring consistent, controlled surface cleaning prior to secondary operations. The machine can be integrated with rolling mills, laminating equipment, or coating lines for complete processing systems, or operated standalone for batch preparation workflows.
