Regrind, Reuse, Reduce

Enhancing sustainability by tool reconditioning and recycling services

Masatoshi Kageyama | OSG Corporation

As a global company manufacturing responsible products, OSG is committed to a healthy planet and society. In order to reduce environmental impact, OSG actively implements initiatives relating to resource and energy conservation, waste reduction, prevention of pollution, and material recycling in various processes throughout the OSG Group.

OSG’s tool reconditioning program is a part of the company’s commitment to promote resource conservation and to improve energy efficiency in its business activities.

The primary benefit of tool reconditioning is obvious: reduction in overall tooling costs. Although many shops regrind their own drills, few shops have given thought to regrinding high performance cutting tools, even though substantial cost savings can be obtained. These efforts not only save customers thousands of dollars each year but are also environmentally friendly and sustainable.

As a comprehensive cutting tool manufacturer, OSG is capable of regrinding and recoating an array of products, such as solid carbide tools, HSS tools, PCD tools, rolling dies, specials, and more. Tool reconditioning services provided by OSG restore used tools to like-new condition. OSG’s tool reconditioning division uses original OSG manufacturing drawings for all regrinding processes. OSG Group companies also adhere to the OSG quality control manual and use the same inspection equipment used by the manufacturing division during the inspection procedures. With tool reconditioning facilities in 14 countries, OSG can respond to customer needs worldwide.

In addition to tool reconditioning, OSG also offers customization services to help manufacturers optimize machining based on individual application needs.

Furthermore, carbide tools that can no longer be reground can be recycled through OSG’s group company’s carbide recycling program. Cemented carbide materials contain a large amount of rare metals. Carbide recycling reduces material consumption and contributes to environmental preservation.

Aoyama Seisakusho Drip Coffee Bags

Aoyama Seisakusho creates promotional items annually to give to customers during special occasions and events. One of its most famously known items is the company’s original drip coffee bag.

Rather than making another orthodox approach to promotional gifts, such as pens and mugs, President Masahiro Oshino wanted to create a unique and memorable gift for clients to enjoy.

“I didn’t want to make just another pen to give to our clients, which may be tossed into the trash,” said Oshino. “As a responsible company, we should be mindful of every environmental impact we make.”

As a coffee enthusiast, Oshino thought that drip coffee bag would make a practical and enjoyable promotional item. In March 2017, Oshino collaborated with a specialty coffee shop in Toyokawa, Aichi, where the company is headquartered at, and the first original drip coffee bag was made. Only high-ranked coffee beans from the specialty coffee category are used in Aoyama Seisakusho’s drip coffee bag, which not only makes this promotional item unique, but also delicious. More than six years later, Aoyama Seisakusho now offers this unique promotional item in 12 different styles featuring coffee beans from Guatemala, Brazil, Ethiopia and Indonesia.

“Pens don’t usually ignite conversations,” said Oshino. “But coffee can,” he says. “It brings people together and is a great conversation starter.”
