Optimal film for difficult-to-machine copper and copper alloy cutting tools - 'SmArc OS-K'
SmArc OS-K
Effective for processing C7025 Kolsun copper alloy used in component terminals, featuring small diameter punches for copper processing and carbide tips.
SmArc OS-K is an improved coating of aluminum chromium nitride specifically designed for the machining of difficult-to-process copper and copper alloys. (This coating is applied under specialized conditions targeting 0.5 microns on our test pieces.) —————————————————————— 【Features】 ■ Effective for machining Koleson copper alloy (C7025) containing nickel/silicon, commonly used for component terminals. ■ Characterized by less adhesion to the cutting edge compared to DLC coatings. ■ High release properties for rubber. 【Examples of Use】 ■ Small diameter punches for Koleson copper machining ■ Carbide tips, etc.

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.
