Release of a case study collection on cutting processing of cutting-edge EV components by Zhengzhou Diamond, the largest PCD and CBN tool manufacturer in China.

A collection of cutting case studies from Zhengzhou Diamond, which supplies a large number of diamond tools for EV parts in China, where EVs are most widely adopted. There are also delivery records in Japan!

China is the world's leading country in EV adoption, accounting for approximately 45% of global EV sales (around 3 million units). Zhengzhou Diamond is China's largest manufacturer specializing in PCD and CBN tools, supplying diamond tools to 90% of automotive manufacturers in China (foreign, Japanese, and local), and has a wealth of experience in tools for processing EV components. We will introduce examples of cutting processes for motor covers and motor rear cases. Since its arrival in Japan in 2009, it has been adopted by major automotive manufacturers, tier 1 suppliers, and major construction machinery manufacturers.

Achieved a 30% cost reduction with the same lifespan and quality as Japanese-made CBN tool manufacturers! Currently adopted by major brake parts manufacturers and truck manufacturers.

Kyoni Co., Ltd. has been engaged in the import and sales of high-quality Chinese tool manufacturers with price advantages to Japan since 2005, and has a track record of supplying to over 1,000 customers nationwide. For brake components such as disc rotors and CBN tools for drum processing, we have a wealth of delivery records in China and Europe, and our products are adopted by major brake component manufacturers and commercial vehicle manufacturers in Japan, achieving tool lifetimes that are 5 to 10 times longer compared to Japanese ceramic chips. Additionally, the lifespan is comparable to Japanese-made CBN tools, while we offer them at a reasonable price that is 30% lower. The Chinese tool manufacturers we propose are "Beijing World Diamond" and "Zhengzhou Diamond," both of which are among the largest specialized manufacturers of diamond tools in China. They supply special tools for engine and automotive parts processing to many automotive manufacturers in China (foreign, Japanese, and local). While they can manufacture extremely high-precision tools, they have achieved approximately 30% cost reduction compared to Japanese manufacturers and are adopted by major automotive manufacturers and parts manufacturers in Japan as well. We are confident that our tools match or exceed the lifespan and precision of Japanese manufacturers, so please start with a test to try them out.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

This is an air leak tester for battery cases of electric vehicles (EVs). The battery case has the characteristic of being "large with a significant internal volume, and its structure may deform due to internal pressure." As a result, air leak testing generates "noise caused by its large size and capacity" and "noise caused by expansion or deformation due to internal pressurization." To mitigate this noise, this device features a newly developed smoothing function and a linear fitting correction function used in combination during measurement. Additionally, to achieve low-pressure control that is difficult to manage and to expand flow for large volumes, we provide a bypass box (CBU-600) equipped with an electro-pneumatic regulator for precise pressure control and a pressurization valve with a large effective diameter to supply high flow rates. Measurement methods: Work-Work comparison, Work-Master comparison, Fixed Master comparison Measurement pressure range: 10 kPa, 20 kPa, 50 kPa (depending on specifications) Gauge pressure sensor accuracy: ±2% F.S. Differential pressure sensor accuracy: ±0.5% F.S. Group settings: 0 to 31 groups Power supply voltage / Power consumption: AC100 to 240 V / 100 VA
