Enhancing sustainability by tool reconditioning and recycling services by 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.  Figure 1. OSG USA Process of tool reconditioning. 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.  Figure 2. Significant cost reduction can be achieved by tool regrinding alone. 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.  Figure 3.

With the capability and expertise to bring worn cutting tools back to life for a fraction of the cost of a new tool, reconditioning is highly economical and environmentally friendly OSG USA's Regrind CapabilitiesOSG USA has comprehensive Regrind and Coating Capabilities for Drills, End Mills, Reamers, Taps and more!

Carbide tools that can no longer be reground can be recycled through OSG’s group company Nihon Hard Metal’s carbide recycling program. by Sean McIntosh, OSG District Sales Manager OSG’s HY-PRO® CARB VGM end mill boosts productivity and lowers cost per part in aerospace bracket application.  From left, Allied Tool & Die CNC Process and Machining Manager Jamie Lerma, CNC Machinist David Dao and CNC Programmer John Hernandez. Founded in 1951 in Phoenix, Arizona, United States, Allied Tool & Die Co. is a family-owned precision machine and fabrication company that specializes in the manufacturing of quality parts for aerospace, medical, communications and commercial industries throughout the world. Seventy years since its establishment, this privately owned shop has grown with multiple facilities and an estimated 32,000 square feet of manufacturing space in Phoenix, Arizona.  CAD / CAM model of a part made from 13-8 stainless steel One of the challenges Allied Tool & Die faced recently was the machining of aerospace brackets made of Inconel 718. As is with most shops, machining Inconel 718 is time consuming. Moreover, due to the material’s special high strength and heat resistance properties, short tool life is a common obstacle. In search for performance improvement, Allied Tool & Die CNC Process and Machining Manager Jamie Lerma reached out to his local OSG representative for new solutions. Lerma had worked with OSG previously on a 13-8 stainless steel application by utilizing OSG’s HY-PRO® CARB VGM series end mill to achieve high-efficiency milling.  A part made from 13-8 stainless steel that was machined by OSG’s HY-PRO® CARB VGM end mill. OSG’s HY-PRO® CARB VGM is a high performance variable geometry end mill series. Its variable index and unique flute geometry enable the reduction of vibration and chatter, promoting smooth and stable cutting with low cutting forces. With the addition of OSG proprietary multi-layer EXO coating, higher wear and heat resistance is achieved to prolong tool life. OSG’s VGM offering features 5-, 6- and 7-flute lineups, and is available with multiple lengths of cut, with both square end and corner radius variations. This series is suitable for carbon steels, alloy steels, die steels, stainless steels, cast iron, nickel alloy, titanium, and hardened steels up to 45 HRC. For the 13-8 stainless steel application, the VGM end mill dominated the machining result by extending tool life from seven parts to 21 parts per tool. The parts were also completed in half the time and the tool cost is also cheaper than the competitor tool. Lerma was so impressed by the VGM end mill that he decided to apply the tool to the Inconel 718 aerospace bracket application.  CAD / CAM model of an aerospace bracket made from Inconel 718. Image courtesy of Allied Tool & Die  An aerospace bracket made from Inconel 718 that was machined by OSG’s HY-PRO® CARB VGM end mill. Allied Tool & Die was previously using a high feed indexable milling cutter for the Inconel 718 aerospace bracket application. However, the amount of time and money spent on changing the inserts was less than desired.
The previous competitor tool was used at 150 SFM (45.7 m/min), 0.009 IPT (0.23 mm/t), 0.05 Aa (ap = 1.27 mm) and 0.75 Ar (ae = 19.05 mm). After reprogramming to utilize OSG’s 0.5-inch diameter 5-flute VGM carbide end mill with a 0.030-inch (0.762 mm) corner radius and 1.25-inch (31.75 mm) length of cut (EDP# VGM5-0143), the cutting parameters were changed to 250 SFT (76.2 mm/min, 2,548 min-1), 0.0022 IPT (0.056 mm/t, 713 mm/min), 0.75 Aa and 0.035 Ar. The application went from a 4-hour cycle time to just one hour and 45 minutes. Allied Tool & Die no longer had to keep stopping the machine to rotate or change inserts, which they were doing four times per part previously. By switching to the VGM end mill, the tool was loaded, and the job did not have to be tended to until the part was completed. In terms of efficiency improvement, Allied Tool & Die estimated that the tool change has generated a cost savings of $6,875 USD on the Inconel 718 aerospace bracket parts. Moreover, with a lower tooling price versus the previous milling cutter, the cost of tooling also decreased by almost $100 USD per part. With the VGM end mill, Allied Tool & Die was able to machine Inconel 718 at an astounding 250 surface feet per minute (76.2 m/min) – a speed that is only commonly seen in alloy or stainless steels, not HRSA materials. With the recent successes, Allied Tool & Die’s CNC Programmer John Hernandez decided to apply the VGM end mill into most jobs he programs. Being such a versatile tool, the VGM can be used to machine anything from common carbon steels up to the nickel alloys required by the aerospace industry. |
