How to add diamond to electroplated diamond grinding wheel?

The process you mentioned is called sand in the electroplating diamond process. There are the following methods for sanding:1

Sand burial method: suitable for small and simple workpieces, such as grinding heads, dental drills, etc., the method is to insulate the unplated part of the workpiece matrix, and the part to be plated is buried in the sand, it is best to place it vertically, the tip is not sharp but has a certain area, the tip should be facing up, so that the pointed part can also be plated with diamond, and pay attention to the sand layer should not be too thick, so that the plating solution is easy to circulate; 2.Sand sprinkling method:

Place the surface to be plated upwards in the plating solution, sprinkle the sand on it with a small spoon or pipette, and sprinkle it thin and evenly, the thickness is generally 1-2 mm. 3.Sand removal method: In fact, this is another sand sprinkling method, that is, the sand is put into the plating tank first, and then stirred, and the workpiece is put into it immediately, and the sand settles naturally and falls on the surface to be plated, or it can be stirred with the workpiece itself, moved up and down, stirred up the sand, and then stopped stirring, and the workpiece was laid flat, and the sand settled on the workpiece.

In the electroplating diamond grinding wheel, it is divided into "sanding" and "sanding" methods.

The "sand spreading method" is to pre-coat the grinding wheel with a layer of nickel, then sprinkle the diamond on the surface of the grinding wheel and continue to plate nickel, so that the diamond is wrapped in the nickel layer.

The doffing method is to first put the diamond in the plating solution, when the pre-nickel plating of the grinding wheel is completed, the diamond is suspended in the plating solution by stirring the plating solution, and then falls on the grinding wheel to continue nickel plating, and the diamond is also wrapped in the nickel layer.

Electroplated diamond is two sand methods: 1 is buried sand 2 is sand shaking, and the specific operation can not be detailed!

Summary. Process flow of electroplating diamond:

Diamond raw materials: degreasing, washing, sensitization, washing, activation, washing, reduction, chemical plating, ni plating, washing, drying. The entire process is carried out at room temperature.

Before plating, the diamond is cleaned, roughened, sensitized, activated and reduced, and then electroless NI plating is carried out.

Pre-Plating Pretreatment:

1) Alkaline degreasing is used for degreasing, in 10 NaOH solution, and a small amount of nonionic surfactant is added to boil for 30min, and rinsed with distilled water for 2-3 times to remove grease and other dirt on the surface of the diamond.

2) Roughening is boiled with dilute HNO3 for 20min and washed 2 3 times with distilled water.

3) Sensitize Log LSNCl2·2H20, 20ml LHCL for 3-5min. Rinse with distilled water.

4) Activate 0 5 g L PDCL2, 10 ml L HCl for 4 min.

5) Reduce 30g LNAH2P02·2H20 for 3min.

Composition of electroless Ni plating solution: 30g LNISO4·6H:O (With the increase of nickel sulfate concentration, the plating rate accelerates, but when the concentration of nickel sulfate exceeds 20g, L, the deposition rate increases less obviously, when the concentration exceeds 30g L, the liquid water does not need to be heated first when the diamond grinding wheel is electroplated.

Summary. Hello dear, the answer to your question about whether to provide electroplating diamond technology is: to date, diamond is still the hardest substance that has been found in nature.

Due to their very high hardness, diamonds can mark almost any object, so they are also often used in industry, such as diamond bezel set on various tool substrates to make some grinding and cutting tools, which is generally achieved by electroplating process.

Hello dear, the answer to your question about whether to provide electroplating diamond technology is: to date, diamond is still the hardest substance that has been found in nature. Due to the very high hardness, diamonds can mark almost any object, so they are also often used in industry, such as diamond bezel on a variety of tool substrates, used to make some grinding and cutting tools, the process of rough hole will generally make the electroplating process to the rock dry and faint.

As early as the 30s of the 20th century, the Germans took the lead in obtaining the patent for the manufacture of diamond dentist bits with nickel plating, which was the beginning of the practical application of diamond electroplating products. By the end of the 40s, the Americans further developed the technology of using electroplating nickel to make diamond products, and with the emergence of synthetic diamond at the end of the 50s, diamond slag electroplating products finally gained industrial application.

Diamond plating is to pile up the diamond on the surface of the tool matrix, the diamond does not participate in all chemical changes, usually has the following composition: diamond ni, diamond ni2co, diamond ni2co2mn, etc. The principle of diamond electroplating is actually that after the electroplating solution and the workpiece are energized, the diamond particles are piled up on the pre-plated workpiece, and then under the action of the electric field, the nickel will release nickel atoms and deposit them on the workpiece that already has diamond particles, and the diamond on the surface will gradually be wrapped up to form the diamond town bright stone plating.

According to the division of the process, the preparation of electroplated diamond tools needs to go through pre-treatment, pre-plating, sanding, sand unloading, thickening and post-treatment.

The main difference between resin diamond grinding wheel and electroplated diamond grinding wheel is the difference in bonding agent, resin diamond grinding wheel mainly uses phenolic resin plus a small amount of metal powder as a binder, while electroplated diamond grinding wheel is a grinding wheel production process that deposits nickel-cobalt alloy on the surface of the metal matrix and fixes diamond abrasives by electrodeposition, and their main differences in performance are:

1. In terms of processing efficiency, because the electroplating grinding wheel uses higher grade abrasives and only one layer of abrasive, it has its own advantages in heat dissipation performance, so the processing efficiency of the electroplated diamond grinding wheel is higher;

2. In terms of service life, the electroplating grinding wheel has only one layer of abrasive, so the service life of the electroplating grinding wheel will be inferior to that of the resin diamond grinding wheel;

3. In terms of machining accuracy, the surface roughness of the workpiece is affected by the same particle size, and the surface roughness processed by the electroplating grinding wheel is worse under the same particle size.

It is mainly used for grinding.

Such as diamond drill bits, emery wheels and so on.

Diamond is characterized by high hardness, can be relatively hard materials for cutting, grinding, grinding, etc., but its inherent sand-like, limiting the play of diamond characteristics, in this case, in order to better make the diamond cemented into the shape required by the tool, the use of including electroplating, the method of making diamond cementation (such as consolidation with glue) is the main method currently used.

The brothers upstairs may be laymen

Electroplating and grinding wheels can be combined, there is a kind of grinding wheel called electroplating grinding wheel, I have been making electroplating grinding wheels for 5-6 years

The main coating component is nickel, and the viscosity of nickel is used to fix the diamond on the surface to achieve the effect of grinding

I have a lot of friends who can operate. But I don't understand the composition and formula of the plating solution, and I have a hand in operation

The application of electroplated diamond grinding wheel in lathe and other industries will be more, and the way of sand is mainly the following three points:

1. Sand burial method.

This method is more suitable for small and simple workpieces. Insulate the unplated part of the workpiece matrix, and bury the plated part in the sand, and pay attention to the sand layer not too thick, so that the plating solution is easy to circulate.

2.Sandshake method.

Put the sand into the plating tank first, and then stir up, immediately put the workpiece in, the sand settles naturally, and falls on the surface to be plated, or it can be stirred with the workpiece itself, move up and down, stir up the sand, and then stop agitation, lay the workpiece flat, and the sand settles on the workpiece.

3.Sanding method.

Place the surface of the electroplated diamond grinding wheel to be plated face up and place it in the plating solution, and then sprinkle the sand on top with a small spoon in a thin and uniform manner, keeping the thickness of 1 to 2 mm.
