Deburring

Burr can vary when punching or laser cutting your materials. Burrs created via laser cutting and punching attach to the material in various strengths. Consequently, finding a comprehensive deburring solution is crucial.

Valgro offers deburring machines for almost every application. The most productive possible sheet metal processing and machining results with deburring and edge rounding of punched, laser, water stream, plasma, or autogenously cut workpieces.

Edge Rounding

A good quality Edge rounding outcome is to identify by removing the sharpness on the Edges of your laser-cut or punched materials. These prevent injuries that may be caused by handling the material, while concurrently improving downstream processing. Moreover, a radius at the Edge of the materials also enhances paint adhesion.

Oxide Removal

If you are cutting via a CO2 -laser with oxygen, the Classic Hybrid can remove any oxide layers along the cutting edge of the material. Automatic steel brush machines by VALGRO INDIA remove the oxide layer on the interior and exterior contours of the laser-cut steel sheet in a single step. Reduce downtime and increase productivity with cost-effectiveness.

De-slagging / Slag Removal

The slag on oxyfuel or plasma-cut parts has to be removed via hand grinding before the actual deburring process takes place. The purpose of the process is to ensure a reliable and efficient upcoming deburring. Appreciation to the machines offered by VALGRO INDIA & manually remove slag is no longer necessary.

Micro Joint Removal

The traditional micro-joint method places small, interconnecting tabs between parts by programming spacing of the slitting punch to leave material unpunched. These burrs may also cause serious injury if not removed.

Surface Finish

Punched and laser-cut parts often require high demands on the surface. A beautiful surface is a pleasant side effect of the deburring process. In some cases, a specific type of surface finish could be necessary. The Valgro Samarth series offers individual configuration options tailored to the customer requirements for high-quality surface finishing, both in dry and wet grinding processes.

Straight Line Grain Finish

A most common finish for stainless steel sheet metal parts with various abrasives belt grinding or brush polishing operation.

Non-Directional Orbital Finish

Non-directional finish also known as random-orbit finish or Vibration Finish, very popular among architects, Non-directional finish has low reflectivity. Non-direction orbit vibration finish is suitable for alloy sheet metal parts for batter adhesions powder colour coating.

Vibration Finish

Vibration Finish sheets are one of the most commonly used finish in stainless steel sheets and plates. Vibration finish is achieved by using a specialized grinding technique, where the grain size is adjusted as per the requirements.

The Shine of the Vibration finished sheets can also be adjusted according to the project requirements. This shine is adjusted by adjusting the base material from 2B, BA or Mirror polished. Applications of the Vibration and Non-Directional finish sheets and plates are found in both exterior and interior paneling. Handrails are also manufactured using the Vibration finish sheets.

Roughening

This applies particularly to thin cold-rolled products, (sheet and coil), and may adversely affect adhesion between the metal surface and the coating system.

Roughening of metal sheet on surfaces prior to coating is essential for batter adhesion or bonding coating chemical and can usually be achieved by abrasive blasting, mechanical sanding or brushing with light abrasion or chemical etching.

A process for manufacturing clad strip is such that a core strip, in particular a metal core strip, is fed to a roll gap formed by at least two rolls and is clad at least on one side by a cladding strip.

Cladding of two metal, Aluminium Composite parts, panel, Non-stick cookware, spray painting, powder coating operation highly recommended surface preparation before coating for batter adhesion or bonding of two different metal
