What types of core barrels are there?

Generally, the instrument manufacturer does this. There is no specific height requirement, but the water-stable layer must be taken through. Generally, the thickness of the water-stable layer does not exceed 50cm, which is completely enough. No power supply is required, the drilling rig and sampling dimensions are accurate, the surface is smooth after drilling, and no accidental damage to the drilled material occurs. It adopts double-column structure and spiral feed mode, which has good stability, simple operation and labor-saving. Equipped with traveling wheels, it is easy to move. It adopts high-speed cutting technology and thin-walled diamond drill bits to drill and cut high-strength reinforced concrete. It has high drilling efficiency, accurate hole positions, smooth hole walls, good hole quality, and complete and smooth core samples. The vibration is small and there is no damage to the building.

Refurbishment method of diamond grinding wheel

As the main part of grinding wheel grinding, the grinding wheel disc is very large in total loss during work. After the grinding wheel has been working for a period of time, its working surface will be passivated. If it is used continuously, the friction between the grinding wheel and the surface of the workpiece will be intensified, thereby affecting the surface quality of the workpiece. Therefore, you should choose an appropriate time to dress the grinding wheel in time. There are three forms of blunt grinding of grinding wheels, namely, blunt grinding of abrasive grains, distortion of the shape of the grinding wheel, and blockage of the grinding wheel. Dressing method of grinding wheel grinding disc 1. Diamond is a commonly used dressing tool. It has extremely high hardness and its sharp angle is 70°-80°. During dressing, the abrasive grains will break when they hit the hard tip of the diamond. As a new micro-tolerance, due to the small contact area between the diamond and the polishing sheet, the elastic deformation caused is also small, so that a finely trimmed surface can be obtained.

What is the difference between diamond grinding wheel and resin grinding wheel?

Before making the comparison, let's explain what are diamond grinding wheels and resin grinding wheels. The so-called resin is also a kind of resin bond. The grinding wheels manufactured by it have very high strength, flexibility, and heat resistance. Low, so it cannot be used in some industries. Diamond grinding wheel is super tough and has no flexibility at all. Its heat resistance is very good, but it is complicated to manufacture and has a long process cycle. Therefore, in the industry, there is a big difference between the two types of grinding wheels. Diamond grinding wheels are widely used in concrete cutting operations, while resin grinding wheels are very suitable for grinding some metal products. In addition, some people may have heard of diamond resin grinding wheel. It is a kind of grinding wheel combined with resin and diamond. It is mainly mixed together, so that mixed cutting can increase its strength when cutting, and in some materials cutting In grinding and grinding, it can effectively control the cutting effect, etc., which is more suitable for grinding and cutting some metal products.

Common dressing techniques for diamond grinding wheels

Diamond grinding wheels have very good grinding performance and are widely used in the grinding of difficult-to-machine materials such as industrial ceramics, cemented carbide, optical glass, diamond tools, and gems. However, the diamond grinding wheel has extremely high hardness, the dressing is quite difficult, and problems such as clogging are prone to occur during the dressing process, which seriously affects the quality of the ground surface and the dressing efficiency, and limits the application of the diamond grinding wheel.
