Valgro Dry Brushing Hot Tempered Strip Machine

Product Description

Elevate your strip finishing process with the Valgro Dry Brushing Hard & Tempered Strip Machine — designed to brush hardened and tempered steel strips in a dry process (i.e., without coolant) to achieve a clean, uniform surface with minimal removal.

Overview

This machine applies heavy-duty rotating brushes to the strip surface to remove approximately 1-2 µm of material and reduce surface roughness (for example from Ra ~1.15 µm to ~0.12 µm) under dry operating conditions. It is built for robustness, vibration-free operation, and maintaining strip flatness (no camber or deformation) even as tough hardened or tempered strips are processed.

Key Features

• Dry brushing process: no coolant used, enabling operation in environments where wet processes are not practical.

• Heavy brush chambers with sealed housings and viewing windows so operators can monitor the process.

• Designed for no strip deformation / no camber, maintaining dimensional integrity of the material.

• Vibration-free, smooth running, and engineered for uniform result from first metre to last.

• Low-noise design (under ~80 dB) and energy-efficient operation.

• Ideal for brushing hardened/tempered strips where scale, hardened surface layers or micro-irregularities need removal but coolant systems are undesirable.

Benefits

• Delivers consistent surface condition across full strip lengths, improving downstream processing reliability.

• Reduces need for further finishing steps by achieving near-final surface quality in one pass.

• Eliminates coolant handling, wastewater treatment, and some maintenance overhead associated with wet systems.

• Helps preserve flatness and material geometry, critical for high-precision strip usage.

• Suited for industrial scale strip processing with high throughput and minimal downtime.

Typical Applications

• Preparation of hardened or tempered steel strip for subsequent processing (coating, bonding, cladding).

• Surface finishing for strips requiring very consistent, low-roughness surfaces before final manufacture in automotive, heavy engineering or precision components.

• Environments where clean, dry processing is preferred (e.g., electronics, specialty steels, thin strip) or where coolant use is constrained.

• Industrial strip lines needing brushing/de-scale plus surface refinement in one integrated step.
