What is the difference between electroplated diamond sanding belt and resin diamond sanding belt?

An old customer in Singapore needs to order an electroplated diamond belt to polish tungsten carbide. Moresuperhard recommends a resin diamond belt to the customer, because the polished surface of the resin diamond belt will be more shiny than the electroplated diamond sanding belt.

What is the difference between electroplated diamond abrasive belt and resin diamond abrasive belt?

1. In terms of binder, the resin diamond abrasive belt mainly uses phenolic resin plus a small amount of metal powder as the binder, while the electroplated diamond abrasive belt is a kind of sand that deposits nickel-drill alloy on the surface of the metal substrate and fixes the diamond abrasive by electrodeposition. With production process.

2. In terms of processing efficiency, since the electroplated diamond abrasive belt uses higher-grade abrasives and has only one layer of abrasive, it has its own advantages in heat dissipation and other aspects, so the electroplated diamond abrasive belt has higher processing efficiency.

3. In terms of service life, the electroplated abrasive belt has only one layer of abrasive, so the service life of the electroplated abrasive belt will be inferior to that of the resin diamond abrasive belt.

What are the advantages and disadvantages of electroplated diamond abrasive belt

1. Advantages

(1) The electroplating process is simple, the investment is small, and the production is convenient

(2) Easy to use.

(3) The single-layer structure determines that it can reach a very high operating speed

(4) Although there is only a single layer of diamond, it still has a sufficient life.

2. Disadvantages

(1) There is no strong chemical-metallurgical bond on the bonding surface between the coating metal, the substrate and the abrasive, and the abrasive is actually only mechanically embedded and inlaid with the coating metal, so the manipulation force is small, and the diamond particles are heavily loaded and easy to fall during efficient grinding (or Plating flakes off) resulting in overall failure

(2) In order to increase the operating force, the thickness of the coating must be increased. As a result, the exposure height of the abrasive grains is reduced, the abrasive belt is prone to clogging, the heat dissipation effect is poor, and the surface of the workpiece is prone to burns.
