We will exhibit at MECT2021 Mechatronics Technology Japan 2021.

A file fits into a gap of 0.3mm to 0.6mm.

We will be launching a new product, "Slit Finish." It is significantly "ultra-thin" compared to conventional files and is ideal for processing gaps that could not be accessed before. It is made from a special material and is designed not to break under normal use.

With numerous edges, it is possible to work on corner sections. The shape is a prism, which allows for the use of flat surfaces, improving work efficiency. Sizes: □0.5, □0.7 Grain sizes: #600, #800.

• Hand polishing and filing

You can take as much as you want, and you can take exactly what you aim for.

The soft bond with a good bite is designed to easily transmit the sensation of the workpiece to your fingertips. It can be used effectively for chipping, burr removal, and precise honing. 【Features】 ○ A well-balanced bond in terms of surface roughness, cutting performance, and durability. For more details, please contact us or download the catalog.

• Hand polishing and filing

Difficult to clog, difficult to chip.

This is a diamond resin bond focused on cutting performance, aimed at reducing clogging without putting stress on the work. Ceramics have a larger variation in strength compared to metal materials, and stress tends to concentrate on defects such as cracks and surface scratches that occur after cutting. It is effective in the removal of defect areas that affect breakage. 【Features】 - Excellent cutting performance for various ceramics - Extremely good surface roughness For more details, please contact us or download the catalog.

• Hand polishing and filing

It is resistant to deformation and has a long lifespan.

It is a bond with a strong ability to retain abrasive particles unique to diamond-petrified materials, making it resistant to shape distortion and providing a long lifespan. It can be used for chamfering, deburring, and finishing, making it a versatile tool to have in the workplace. 【Features】 - Excellent cutting ability that is not limited to specific materials - Outstanding durability For more details, please contact us or download the catalog.

• Hand polishing and filing

Rich variety, selectable granularity

The vibrant green pattern uses rubber material that places less burden on fieldwork. Color rings are attached for easy identification of granularity. We offer a lineup of granularity not found in other companies, catering to material, application, and processing purposes. 【Features】 ○ A handle that feels easy to grip ○ Easily recognizable colors ○ A wide range of granularity tailored to your needs For more details, please contact us or download the catalog.

• Hand polishing and filing

Three types for different applications are lined up as standard products, capable of meeting various site needs.

Leveraging our experience and achievements as a DIA/CBN whetstone manufacturer, we have created essential hand tools for manufacturing. We are committed to handmade production in-house, from the types of diamond abrasives to the materials, shapes, and finishes of the handles. The Hand Meister series features three types as standard products, catering to various applications and environments. 【Product Lineup】 ○ Multi-Finish: A versatile type that works with any material ○ Cerami-Finish: For various ceramics ○ Tool-Finish: For cutting tool edge treatment ○ Diamond Files: A wide variety with selectable grit For more details, please contact us or download the catalog.

The diamond paste comes pre-mixed with a diluent, so there is no need to mix it yourself. It is in gel form, so you can use it immediately after taking it out of the container.

"Miragel" is hassle-free, uniform, and waste-free. The diamond paste is pre-mixed with a diluent to achieve the optimal viscosity for wrapping, so you can use it immediately after taking it out of the container. Being silicone-based, there is no concern about alteration or degradation. It does not contain harmful substances, allowing for safe use. The need to purchase diluent is eliminated, resulting in cost savings. We offer three types based on the amount of diamond, all at a uniform price. Additionally, under our quality control, it is mixed using a dedicated machine with a standardized formulation. It can be applied directly to wrapping tools and workpieces, allowing you to use only the necessary amount. For more details, please download the catalog or contact us.

• Grindstone

A highly versatile oil-based diamond paste that is easy to spread and blend. Additionally, the price remains consistent even if the diamond content ratio changes!

"Mirror Paste" is finished with carefully selected ingredients for high efficiency and precision. The specialized oil with excellent lubricity and uniformity maximizes the performance of diamonds. It is formulated with an optimal viscosity for polishing, which also improves work efficiency. With the dedicated diluent, you can use it at a freely adjustable viscosity while maintaining the performance of the diamonds. It does not contain harmful substances to the human body, making it safe. The syringe comes with a highly sealed screw cap. Please use the included diluent when using it. For more details, please download the catalog or contact us.

• Grindstone

It is ideal for jobs that are difficult to clean with oil. Since it is water-soluble, it can be easily washed away with water. Additionally, the price remains uniform even if the diamond content ratio changes!

"Aqua Paste" is formulated with water-soluble ingredients that are ideal for both polishing and cleaning. It uses only safe materials and does not contain any harmful substances for the human body, so you can use it with peace of mind. If you are using a diluent, please use the one provided. For more details, please download the catalog or contact us.

• Grindstone

We bring out a new shine with the latest abrasives.

We use abrasive grains that allow for more cutting edges to repeatedly perform moderate micro-fracturing, resulting in a high-quality finish that is less prone to scratches, making them ideal for polishing. Additionally, we offer high-concentration grades with increased diamond content, such as GOLD SILVER.

Technoa Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Koji Yamazaki) will hold a limited-time summer special event, "Monozukuri DX CAMP," from Saturday, August 9, 2025, to Saturday, August 23, 2025. Small and medium-sized manufacturing companies face challenges such as a shortage of specialized personnel and a lack of know-how and information, which act as barriers to promoting DX (digital transformation). This event will provide a step-by-step approach to "realistic DX," based on the know-how accumulated by Technoa while supporting the DX transformation of small and medium-sized manufacturing companies. It will be structured as DAY.1 to DAY.5, offering an opportunity for skill development during the summer break and supporting the learning and growth of small and medium-sized manufacturers. For more details, please refer to the related link.

JOHNAN has released a video that clearly explains the implementation technology for stretchable films, which are expected to be utilized in wearable devices and medical equipment. In the video, you can see how the film, which has excellent elasticity, stretches and contracts. Please check our high technological capabilities and the flexible characteristics that are useful for product development. We hope this will help you generate new ideas in product development. ▼You can watch the video here [Link to the implementation page for stretchable films] https://www.johnan.com/dms/mounting/filmdevic/stretchable/

"Because it's an invisible place, we won't overlook it." Japan's climate is characterized by high temperatures and humidity, and particularly after typhoons and heavy rains, the conditions can be harsh for homes. It's not just the roofs and exterior walls that are affected by rain and wind. The area beneath the floor is actually the most susceptible and often overlooked point. This time, we will explain the "checkpoints for under the floor" that should be confirmed after a typhoon or heavy rain, the "responses" if abnormalities are found, and measures for preventing recurrence. [Table of Contents] ■ Why is underfloor checking necessary? ■ Checkpoints to confirm after a typhoon or heavy rain ■ Responses when damage is discovered ■ Points for preventing recurrence ■ Suggestions from Seihou Products ■ Summary Please be sure to read the [related materials] and [related links]. ↓ ↓ ↓
