What causes imbalance in a rotating body?

Explanation of the main causes of imbalances, such as "uneven mass distribution occurring within the rotating body material"!

"Unbalance" refers to a state where the center of gravity of a rotating body is not aligned with the axis of rotation. When a rotating body is spun in this state, centrifugal force is generated. The main causes of unbalance include "uneven mass distribution within the material of the rotating body." During the manufacturing process, grinding wheels and cast products can experience uneven distribution of abrasive particles or the formation of internal voids, leading to variations in the mass distribution of the rotating body. [Main Causes of Unbalance] ■ Uneven mass distribution within the material of the rotating body - Grinding wheels and cast products can develop uneven distribution of abrasive particles or internal voids during manufacturing, resulting in variations in the mass distribution of the rotating body. ■ Misalignment during the fitting of the rotating body onto the shaft - The hole diameter for fitting the rotating body onto the shaft is not perfectly equal to the shaft diameter, which can cause misalignment from the center of the shaft during the fitting process. *For more details, please refer to the PDF document or feel free to contact us.

Super finishing stone / ZP stone

Whetstones with extremely low processing alteration and whetstones that achieve waste reduction without using environmentally harmful substances.

We would like to introduce our "Super Finishing Stone/ZP Stone." The "Super Finishing Stone" applies vibrations to the grinding stone, exerting forces on the abrasive grains from multiple directions, making it easier for the grains to break and fall off, while maintaining a consistently sharp cutting edge. This ensures the grinding performance of the stone. The "ZP Stone" is a grinding stone that meets environmental standards by not using materials such as lead, which are harmful to the environment. It has a good pore balance and achieves suitable grinding performance. 【Features of the Super Finishing Stone】 - Facilitates the breaking and falling off of abrasive grains, maintaining a consistently sharp cutting edge - Ensures the grinding performance of the stone - Processes at lower pressure and speed compared to general machining - Generates almost no heat, resulting in extremely low machining alteration compared to grinding - By using specialized machinery, it achieves high precision in surface roughness and shape accuracy economically in a short time *For more details, please refer to the PDF document or feel free to contact us.

Porous grinding stone "PT"

The roots of porosity theory: It is possible to finely adjust the pores and also to adjust the hardness of the whetstone using the pores.

"PT" refers to porous grinding wheels that allow for free control over the size and quantity of pores, enabling design and manufacturing. The key point in processing workpieces with low melting points is to minimize the generation of grinding heat. To meet these conditions, a large number of large pores are necessary. The PT grinding wheel makes it possible to freely control the size and quantity of these pores. Since the pores can be finely adjusted, it is also possible to adjust the hardness of the grinding wheel using the pores. It is mainly suitable for soft, sticky materials like rubber and resin, which are sensitive to heat. 【Features】 - Less prone to clogging, resulting in longer dressing intervals. - Provides a good cut, making it less likely to cause chatter or feed marks. - Even with fine grain sizes, it maintains good grindability, resulting in a smooth finish and reduced scratching. For more details, please contact us or download the catalog.

Semi-porous grinding stone "PT II"

Cut cleanly with large pores and increase surface roughness with small pores.

It exhibits performance that combines the pore characteristics of PT grinding wheels, which allow for good chip discharge and suppress heat generation, with the structure of general grinding wheels that excel in metal machinability. It is optimal for processing materials such as stainless steel (300 series), copper, and aluminum, which are tough and have significant changes due to heat. Additionally, it is suitable for processing on magnetic tables of surface grinding machines. 【Features】 - Grinding wheels with pores suitable for metal processing - Good chip discharge leads to less heat generation - Excellent processing accuracy due to cool cutting For more details, please contact us or download the catalog.

Giant Pore Grinding Wheel "PT Magnum"

It has large pores, so it cuts well! The discharge of cutting dust is very good! Large pore grinding wheel.

The "PT Magnum" is a giant porous grinding wheel that has further evolved from Teiken's long-selling PT grinding wheel. The maximum pore diameter reaches up to 6mm. Additionally, by combining it with small-diameter pores, the porosity rate has also been improved. It demonstrates outstanding effectiveness for workpieces that are sensitive to heat, processes that generate a large amount of chips, and processes that are prone to clogging. Depending on the application, further benefits can be expected by differentiating its use from the PT grinding wheel. 【Features】 - Excellent cutting performance due to the large pores - Very good chip discharge - Extremely resistant to clogging For more details, please contact us or download the catalog.

High performance, high efficiency grinding wheel "RZ"

High-performance, high-efficiency grinding wheels achieve minimal wear and tear through submicron micro-fracturing.

RZ is a high-performance grinding wheel made from a microstructure of polycrystalline composite abrasives composed of non-melting alumina ceramics. It achieves a grinding wheel that cuts with minimal wear due to submicron micro-fracturing. The performance difference is 2 to 6 times greater than conventional WA-type grinding wheels, resulting in significant reductions in processing time. Additionally, it is resistant to clogging and maintains cutting ability even at smaller diameters, offering excellent cost performance. When used in conjunction with a dedicated RZ dresser, further effects can be expected. 【Features】 - High performance compared to conventional general grinding wheels - Easy shaping processing that is difficult with CBN wheels - Low grinding resistance even with high depth of cut - Extended dressing intervals For more details, please contact us or download the catalog.
