Electroplating is a manufacturing process that involves fixing abrasive grains onto a substrate using a metallic deposit created through electrolysis. This technique is commonly used in the production of sanding and cutting discs, particularly in the fields of stone, glass, and composite material processing.
How does electroplating work?
The process relies on an electrolytic bath in which a substrate (disc, blade, etc.) is immersed. An electric charge allows a thin layer of nickel or another metal to be deposited onto the substrate, incorporating abrasive grains (diamond, silicon carbide, etc.). These grains are firmly and uniformly anchored, providing excellent durability.
What are the advantages of electroplated tools?
- Exceptional sharpness: since the grains are exposed and not embedded in a bonding agent, they cut immediately and efficiently, offering optimal aggressiveness from the first use.
- High precision: electroplating ensures a highly uniform distribution of grains, guaranteeing a clean and consistent cut—essential for delicate applications such as marble or glass cutting.
- Minimal heat build-up: unlike bonded or sintered tools, electroplated discs dissipate heat more effectively, reducing the risk of overheating and material damage.
- Extended durability in certain applications: although their lifespan may be shorter than sintered discs due to the absence of reserve grains, their consistent performance throughout their usage compensates for this.
- Ideal for hard-to-cut materials: electroplated tools are particularly suitable for hard and brittle materials such as marble, ceramics, or glass due to their clean and precise cutting action.
Common applications of electroplated discs
- Sanding and polishing stone: marble, granite, quartz
- Cutting fragile materials: glass, ceramics, composites
- Precision work: stone engraving, fine finishing
Electroplated tools are an essential solution for professionals seeking fast, precise, and efficient cutting on demanding materials.
