■Oxidation resistance at 1000℃ ■High hardness of 3000Hv ■High heat resistance and high hardness film of aluminum-chromium system 【Tools for dry processing】【Dry cutting】【Heat-resistant molds】
OS-A is an improved ceramic coating that adds silicon to aluminum chromium nitride coating. —————————————————————— 【Features】 ■ Compared to titanium aluminum nitride coating (TiAlN), it offers higher heat resistance and hardness, making it particularly effective in preventing crater wear (adhesion diffusion wear) when machining iron-based materials. ■ It is also ideal for mold components that require heat resistance and high hardness. [Made to order] 【Examples of Applications】 ■ Tools for dry machining (HSS tools) ■ Dry cutting tools for general steel (S50, S45C, FC, SMC, etc.) ■ Gear cutting tools ■ Heat-resistant molds, etc. *For detailed specifications, please refer to the catalog or the official website product information.

Company information
Onward Giken is an expert company that specializes in contract processing for surface treatments such as DLC and ceramic coatings. 【Pioneers in DLC Film Development with High Technology for Both Equipment and Films】 In 1986, we were among the first in Japan to introduce film deposition equipment, and in 2001, we completed our own developed DLC equipment. Since then, we have continued to develop new films and now handle a variety of coatings, including 13 types of ceramic films and 8 types of DLC films, with numerous patents obtained. 【Development Technology + Years of Experience + 21 Types of Films = Onward's Proposal Power】 At Onward Giken, we propose the most suitable film for our customers from over 21 types of coatings based on our self-developed "film deposition technology" and the data obtained from more than 30 years of extensive "experience." First, our sales representatives listen to the customer's needs and the issues they want to solve, and then our internal team analyzes them. Additionally, with the support of the Technology Development Research Department responsible for equipment development, we consider solutions across all departments to address the customer's problems. 【Support for Development Prototypes and Small Lots from One Item】 Orders of 5 items or fewer per lot account for 79% of our total orders. We also regularly handle orders starting from one item. We are happy to accept inquiries from universities and companies regarding development projects.
