Our Product / Services
Our product range contains a wide range of Valgro Dry Brushing Hot Tempered Strip Machine and Valgro Dry Grinding Hard Temper 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.
Product Description
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.
Overview
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.
Key Features
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
Benefits
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
Typical Applications
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
