 Description:

There is a self-developed platform about advanced porous metal bond superhard abrasive technology in the company. By using metal bond technology, the effective chemical metallurgical connection between abrasive and metal bond has been realized in both CBN and diamond abrasives. The porous metal bonded superhard grinding wheels produced can be widely applied in various fields, such as cemented carbide cutting tools, automotive crankshafts and camshafts, high-precision manufacturing of aerospace engines, and rail transportation. These products break the monopoly of foreign technologies, and can meet the high-precision requirements of blades of titanium alloy and high-temperature alloy in aerospace engine. They have excellent performances, such as good processing accuracy and surface finish, and good wear resistance, long life and low power loss, and have a strong competitive advantage compared with traditional products, and are applied to a wide range of applications.

The new generation of porous metal bond technology, which is based on the self-developed high-performance alloy system, adopts advanced metallurgical technology without adding any pore-forming agent to produce the porous structure product prepared by sintering. The effective chemical metallurgical combination of the abrasive and the binder greatly improves the retention and exposure rate compared with the traditional physical embedding structure. At the same time, the porous structure has good heat dissipation capacity and easy dressability reduces the frequency of sharpening and dressing greatly, and even eliminates the need for dressing during the conditioning cycle, and greatly improves the processing efficiency and service life.

Technological innovation:

In the high-speed and high-efficiency heavy load grinding, abrasive grains are firmly held, the heat dissipation is good, and the exposed height of the abrasive grains can reach 70%~80%, which increases the space for chips. The grinding wheel is not easy to clogging, and easy to condtion, the service life is more sufficient, Metal bond superabrasive grinding wheel has excellent grinding performance, such as lower power loss and grinding temperature, and can realize ultra-high speed grinding of 200~300m/s, which is of great significance in manufacturing industries.

Compared with traditional diamond grinding tools:

1.Improve tool life by 35% 

2.Significantly reduced the frequency of sharpening and trimming
3.Grinding accuracy reaches 0.025 μm 4..Grinding speed increased by 2-3 times

Product application areas:

1. Hard Alloy Cutting Tool – High-Performance Slotting Grinding Wheel: 

PANWEI has primarily developed high-performance slotting grinding wheels characterized by exceptional grinding force, excellent self-sharpening properties, and resistance to clogging. These wheels are specifically designed to meet the demands of high material removal and intensive slotting operations in the hard alloy industry. 

1.The porous honeycomb structure endows the product with better chip capacity and self sharpness. 

2. Higher concentrations of abrasive endow the product with ultra strong grinding force, greatly improving grinding efficiency. 

 3. The chemical metallurgical combination of binders and abrasives endows the product with strong grip and better shape retention and lifespan.

2.The metal ceramic cutting tool industry

Metal ceramics are known as the new generation of cutting tool materials. Compared with hard alloy milling cutters, metal ceramic milling cutters have a longer lifespan and higher workpiece smoothness. When using conventional grinding wheels for processing, the particle size is too fine and cannot be moved during processing. If the particle size is too high, it is easy to break the edge. At present, diamond grinding wheels, which are the same as hard alloy slotting, are still commonly used in the processing of ceramic cutting tools. However, traditional slotting grinding wheels, including imported products, are difficult to break through 125% of abrasive concentration due to process limitations. During the processing, it is easy to produce problems such as tool product breakage and substandard smoothness, and the product qualification rate is not high, making it difficult to meet the standards for batch shipment. Our company's products have ultra-high abrasive concentration and are not limited by traditional processes. Therefore, we use high concentration and fine-grained technology to solve the problem of batch production of metal ceramic milling cutters in China. Currently, we are the only grinding wheel supplier that can meet the batch shipping standards of ceramic tool manufacturers in terms of processing quality and efficiency.

3.Blade peripheral grinding products

The good sharpness and non clogging characteristics of Panwei peripheral grinding products endow the peripheral grinding wheel with lower spindle load power, lower repair frequency, and longer service life during use. The traditional products in the domestic market are mainly resin binder products.

4.High speed steel tool series:

High speed steel tool cutting tools often cannot use the most efficient CBN superhard grinding tools due to the requirements for grinding wheel dressing and shaping, but generally use low-end alumina grinding tools with low added value and easy wear.Panwei products demonstrate significant advantages in process upgrades due to their excellent shaping and repair properties. When processing large-sized high-speed steel drill bits with ordinary grinding corundum grinding wheels, each piece needs to be repaired once, which seriously affects production efficiency. After replacing with Panwei products, the grinding wheel life is increased by more than 300 times for every 300 pieces processed, greatly improving production efficiency, and the grinding fluid does not need to be changed frequently. According to user calculations, the overall production cost still decreases by 49%.
