Harden n Tamper Steel Strip Polishing

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.

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.

• 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.

• 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.

• 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.

Enhance precision and surface quality in your strip processing line with the Valgro Dry Grinding Hard & Temper Strip Machine. This machine is engineered to grind hardened or tempered steel strips in dry mode with a robust dust-exhaust and filtration system, making it ideal where coolant processes are undesirable or impractical.

During the production of hot strips, surface defects such as scale, roughness, or micro-scratches often transfer downstream, affecting product quality. The Valgro Dry Grinding Hard & Temper Strip Machine removes these defects while preserving flatness and structural integrity. With its advanced dry grinding design, it ensures a clean, uniform surface suitable for cladding, coating, or further processing.

• Designed specifically for dry grinding of hardened and tempered strips, featuring an efficient dust collection and filtration system

• Vibration-free operation with uniform surface results from start to finish

• Guarantees no strip deformation or camber, maintaining consistent flatness

• Low-noise operation (<80 dB) with smooth and continuous feed performance

• Energy-efficient system, minimizing power consumption and overall operating cost

• Delivers consistent, high-quality finishes on hardened and tempered strips

• Eliminates the need for wet coolant systems, ideal for facilities with cooling or wastewater restrictions

• Reduces rework and scrap by improving surface condition before further processing

• Supports high-throughput industrial strip processing with stable, long-term performance

• Pre-finishing of hardened or tempered steel strips used in cladding, bearings, and electronic components

• Surface preparation for ultra-flat, defect-free strips before coating, plating, or bonding

• Suitable for heavy-duty strip processing lines where coolant use is limited or dry operation is preferred

Enhance your strip surface quality with the Valgro Wet Grinding Hard & Temper Strip Machine, designed for precision grinding and surface improvement of hardened or tempered steel strips before further processing or roll cladding.

In hot-strip production, surface defects like scale and irregularities can compromise downstream performance. The Valgro Wet Grinding Hard & Temper Strip Machine effectively removes these imperfections, delivering a clean, smooth, and uniform surface. This wet grinding system uses a coolant (emulsion or grinding oil) for controlled temperature and improved tool life — ideal for demanding industrial environments.
