We confirmed double the lifespan with FC250 processing. Would you like to try its effects at your site as well?

A demonstration experiment was conducted under conditions where blade edge damage is likely to occur, using cast iron (FC250). When applying the DK cryo process to drills with different specifications—cobalt high-speed steel with TiN coating and carbide with EgiAs coating—it was confirmed that both achieved over twice the lifespan compared to those without treatment. Currently, the demonstration experiment includes only one case each for carbide and high-speed steel in FC250. This may be coincidental. Nevertheless, the fact that similar results are observed despite different base materials is noteworthy as a trend. Furthermore, price revisions by various carbide tool manufacturers are also planned. Given that tool costs are rising during this period, the importance of the perspective of "using tools for a longer time" has increased more than ever. If this is the result in cast iron processing... how will it manifest in your workplace? Please feel free to contact us. We also have a collection of case studies organized by project available.

Not just finishing with regrinding. By combining with the DK Cryo Process, we further extend the tool's lifespan.

There are three options for improving the lifespan of tools: "regrinding," "deep cryogenic treatment (DK cryo process)," and "a combination of both." In this service, we provide optimal proposals based on the condition of the tools and usage conditions, whether it be regrinding only, DK cryo process only, or a combination of both. Not only does regrinding restore cutting performance, but combining it with the DK cryo process can also lead to further lifespan improvements, such as chip suppression, wear reduction, and enhanced processing stability. We cater to general tools like end mills and drills, as well as regrinding for irregularly segmented and irregular lead tools, which have limited companies capable of handling them. This document introduces methods for utilizing the combination of regrinding and the DK cryo process, along with improvement case studies. Please take a look at the materials.

For those troubled by the lifespan and chipping of mold parts and cutting tools, we introduce the concept of deep cryogenic treatment "DK Cryo Process."

The DK Cryo Process is a deep cooling temperature treatment applied to mold components and cutting tools. This treatment is not merely aimed at improving hardness or toughness. It focuses on the stress state at the boundaries between different microstructures within the material, and by balancing these stresses, it suppresses cracking, chipping, particle detachment, and crack propagation, thereby improving the lifespan of mold components and cutting tools and enhancing processing stability. It can be widely applied to mold components such as punches and dies, as well as cutting tools like drills and end mills. Additionally, it accommodates a variety of materials including carbide, high-speed steel, die steel, and cermet, and can be applied to coated products or those currently in use. This page introduces the basic concept of the DK Cryo Process. For detailed improvement cases and examples, please refer to "Applications and Case Studies." Feel free to contact us regarding processing feasibility or estimates.

Even ultra-hard materials can chip... There may be ways to counteract that chipping.

It is often said on-site: "Since it's carbide, chipping is inevitable." While it is true that high hardness makes chipping more likely, are you giving up on improvement by saying "it can't be helped"? → In fact, that chipping may be preventable. ■ An option to make chipping "less likely to occur" One of these is the DK Cryo Process. By treating mold components, we can: - Suppress the occurrence of chipping - Reduce replacement frequency - Achieve stable lifespan From "replace when chipped" to "use until the end." We have also confirmed actual results of chipping suppression and lifespan improvement with carbide (KD10). First, please check the case study materials.

DK Cryo Process that suppresses coating peeling and chipping, maximizing performance.

Even with coating applied, there are cases where sufficient performance is not achieved due to early delamination or chipping of the cutting edge. This may be influenced not by the coating itself, but by the instability of the base material's structure or internal stresses. The DK Cryo Process is a technology that enhances the toughness and wear resistance of the base material by promoting the transformation of residual austenite and stabilizing the metal structure through ultra-low temperature treatment. This strengthens the foundation that supports the coating, leading to improved adhesion and alleviation of stress concentration, thereby suppressing the occurrence of delamination and chipping. As a result, it brings out performance that could not be fully realized by the coating alone, contributing to reduced variability in tool life and maintaining stable processing quality. Additionally, this treatment can be applied after existing heat treatment and coating processes, allowing for implementation without the need for process changes or new equipment investments. It contributes to overall cost improvement in the field by extending tool life, reducing replacement frequency, and decreasing maintenance labor.

Suppressing chipping and damage of molds, leading to a stable mold lifespan. This processing technology is utilized as a countermeasure against chipping and damage in press molds and tools.

In press molds and cutting tools, chipping (nicks) of the cutting edge and early wear are significant challenges. The DK Cryo Process is a deep cooling treatment technology that stabilizes the metal structure by processing materials in an extremely low-temperature environment, achieving: - Suppression of chipping occurrence - Improvement of wear resistance - Enhancement of dimensional stability This contributes to the improvement of the lifespan of molds and tools. It can be applied by adding it after existing heat treatment processes, which is a notable feature as it does not require special equipment modifications for implementation. It is utilized as a performance enhancement technology for parts such as mold components and tools, where durability and stability are required.

The sales system for Hyper CLT sheets has expanded in Okinawa. Recently, "Kokoharete" in Okinawa Prefecture has become a distributor for Hyper CLT sheets. This has established a system that allows us to propose products more closely to construction companies and civil engineering contractors within Okinawa Prefecture. Hyper CLT sheets are civil engineering sheets that utilize wood CLT. They can be widely used for temporary roads, access roads, heavy machinery work yards, material yards, and are characterized by being lightweight and easy to install and remove. Additionally, they can be used for environmental considerations and heat countermeasures, such as reducing glare and radiant heat unique to wood, lowering metal noise, and fixing CO2. Furthermore, as a registered technology under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS "TH-250021-A," they can also be proposed for the utilization of new technologies and creative ideas in public works. We will expand the new options of wood, NETIS, civil engineering, and CLT to the sites in Okinawa from now on.
