Whetstone sintered corundum (ruby) : A kind of microcrystalline corundum product sintered at high temperature. It has a compact and delicate structure and high hardness and strength.
The products are rosy red. The products are small grinding wheel type whetstone, standard type whetstone and grinding head type whetstone. When grinding the workpiece, it can maintain sharp edge and stable geometry for a long time.
It is suitable for forming and grinding of instrument industry, precision parts, micro cutting tools, tools and precision abrasive tools, etc. The precision surface roughness of machining can reach about 0.05μm.
Product SPECIFICATIONS: flat sand wheel whetstone with diameter less than 100 for small grinding wheel type, whetstone with various geometric shapes less than 200*50*25 for standard type, whetstone with diameter less than 25 for grinding head type.
Grinding method
About diamond grinding paste, particle size from W40 to W0.5. W40 is the coarsest, with a large amount of grinding, and W0.5 is the smallest. It is used for polishing, and it does not anneal, and it can also grind the hard knife.
Method of use:
The coarse W40 abrasive paste applied to borotartar can accelerate and increase the grinding amount without annealing.
Then, AFTER the rough grinding paste on the knife is cleaned, W0.5 grinding paste is applied to the ruby or natural jade for polishing, and the effect thrown out is a mirror.
Green silicon carbide, white corundum, brown corundum of these three kinds of whetstone hardness is not enough, coupled with a little coarse particle size, easy to grind out the cross, and the other three kinds of whetstone in polishing, grinding will not annealing.
If the particle size is greater than 1000, there is no difference. It mainly depends on the grinding paste used. When the grinding paste of W1.5 is applied to the ruby with 1000 mesh, its grinding effect is the effect of the grinding paste of W1.5, that is, the effect of the whetstone with 2500 particle size

Kuroda Seiko: 88 years of precision manufacturing history
**Abstract:**
The manufacturing history of Kuroda Seiko Grinding Machines dates back to 1953, when the company developed its first forming surface grinder in response to the growing demand for precision mold processing. Over nearly six decades, Kuroda Seiko has continuously refined its technology and accumulated extensive experience in producing high-precision stamping dies. This expertise has been supported by the continuous development and supply of precision gauge technology, ensuring that their profiled surface grinders maintain a high level of accuracy and reliability.
Kuroda Seiko, originally established in 1925, began its journey in the field of precision measurement. The company's core philosophy has always been to pursue perfection, which led to the creation of a wide range of high-precision products, including ball screws, tool holders, precision stamping dies, forming Grinding Wheels, measuring devices, and gauges. Even after more than 80 years, Kuroda Seiko remains committed to its original mission, striving to achieve near-zero tolerance in every product it produces.
In addition to its long-standing reputation in precision measurement, Kuroda Seiko also made significant contributions to the development of surface grinders. The company’s forming surface grinders are equipped with high-precision ball screws manufactured in-house, ensuring exceptional stability in feed and positioning accuracy. With a feed unit of 0.0001mm, these machines allow even inexperienced operators to perform precise grinding tasks. The machine’s left-right sliding table is designed for high-frequency operation, making it a critical component for maintaining long-term precision and durability. The VV shovel sliding method further enhances the verticality and longevity of the machine.
Kuroda Seiko also employs an exclusive hydraulic and dynamic spindle structure, enabling it to handle difficult-to-grind materials such as superhard alloys and high-precision molds with ease. This innovation ensures superior surface quality and accuracy, meeting the demands of industries that require extreme precision.
One of the key milestones in Kuroda Seiko’s expansion into China was the establishment of Pinghu Kuroda Seiko Co., Ltd., a Sino-Japanese joint venture, on October 11, 2001. This partnership opened new opportunities for Chinese users to access Kuroda Seiko’s advanced machinery. In recent years, as the demand for precision in China has evolved, Kuroda Seiko has adapted its strategy to meet the needs of a broader audience. Previously focused on skilled technicians, the company now offers machines that can be operated by individuals without prior experience, making high-precision grinding more accessible.
The "New Generation Mechanics-45 Series" from Kuroda Seiko has become a crucial platform for the advancement of industries such as electronics, semiconductors, and medical equipment. These machines have played a vital role in the production of precision connectors, optical guides, and high-speed stamping parts, contributing significantly to the growth and innovation of these sectors.
