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.

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.

For many years, we have pursued the performance of grinding wheels by focusing on abrasive grains and high-strength bonds. The Dolce series features a new bond that acts more flexibly and softly, combined with a new grinding wheel that has the optimal size and amount of pores for high-hardness metal workpieces. The porosity rate is equivalent to the polar type "PT II" for soft materials. The grinding sound is light and soft, making it effective for high-hardness workpieces, thin materials, and workpieces with low rigidity. Additionally, the generation of heat is minimal, allowing for finer grain size settings than before. There are three types of abrasives: the high-performance "RZ type," the "SPW type" that can process materials from raw to hardened steel, and the "HW type," which is a mix of WA and GC. [Abrasives] ○ "RZ type" using high-performance ceramic abrasive grains ○ "SPW type" capable of processing from raw materials to hardened steel ○ "HW type" that allows a mix of WA and GC For more details, please contact us or download the catalog.

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.

"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.

In improving the resin bond DIA and CBN wheels so far, we have responded to various grinding needs through enhancements in abrasive materials, bonds, fillers, and concentration levels. However, we have still received strong expectations, requests, and challenges from our customers regarding the handling of difficult-to-grind materials, requirements for precision, efficiency, surface quality improvements, and cost reductions. To address these challenges, we have successfully developed and completed a new yet old technology: the porous wheel.
