Toyota Motor Corporation was honored this month for its ongoing efforts to promote a sustainable society by reducing, reusing and recycling resources, such as tungsten and tungsten carbide materials.

At this year's 3Rs (Reduce, Reuse, and Recycle) Awards hosted by Japan's Ministry of Economy, Trade, and Industry (METI) 3Rs Promotion Council, Toyota and Toyota Tsusho Corporation shared the 2013 Prime Minister's Prize.

Separately, Toyota and Sumitomo Electric Industries, Ltd. shared a Rare Metal Recycling Award from the Japan Environmental Management Association for Industry (JEMAI) presented earlier this month at the Awards for Resources Recirculation Technologies and Systems. The award, announced on October 11, recognized the companies' jointly developed system for recycling the rare metal tungsten.

Toyota was one of the first automakers to respond to the implications of mass production and disposal of vehicles. In 1970, Toyota and Toyota Tsusho Corporation founded Toyota Metal Co., Ltd., the first end-of-life vehicle shredding plant established by an automaker. The Toyota Group (consisting of 17 companies including TMC and Toyota Tsusho Corporation) has remained committed to the responsible disposal of end-of-life vehicles, and has developed a wide variety of world-first recycling technologies and systems to recover tungsten materials.

Toyota is also working to recycle rare metals that are used in non-hybrid vehicles. In 2010, Toyota teamed up with Sumitomo Electric Industries to establish a business focused on recycling tungsten, which is most commonly used to produce highly resilient carbide tools. The system combines processes for sorting and collecting scrap from cemented carbide products with new, world-first recycling technology to enable 100 percent recovery and recycling of tungsten in cemented carbide scrap. To date, the venture has recycled 75 tons of tungsten.

German sawing machine manufacturer, KASTO, has introduced a new, automatic circular saw called KASTOgripspeed C10. It can be fitted with equipment for continuous stock infeed and with various outfeed options, including sorting of cut pieces.

The high performance machine is designed to process materials up to a tensile strength of 1,400 N/mm². Tungsten carbide tipped saw blades of 360 mm diameter and either 2.5 or 2 mm thick minimise the kerf and hence the amount of metal lost as swarf. For some materials, coated or cermet blades are used.

All such blades have the additional advantage that thin or thin-walled materials can be cut safely and efficiently, expanding the range of applications for which the KASTOgripspeed C10 is suitable. Particularly helpful is infinitely adjustable workpiece clamping with a force of 2 to 12.5 kN for safely securing thin-walled tubes and profiles.

Cutting range of the saw is from 15 to 100 mm diameter for rounds or up to 80 mm for square stock. The smallest cut-piece length is 8 mm, while remnant length is only 65 mm. Material feed stroke is 500 mm, or up to 9,999 mm with multiple feed.

Saw drive power is high at 11 kW to ensure efficient cutting of all type of material. Infeed speed ranges from 10 to 4,000 mm/min and is infinitely variable. The same is true for blade speed, which is adjustable from 17 to 175 m/min. Contributing to short idle time is 10 m/min rapid lift of the saw blade at the end of each cutting cycle.

To maximise productivity, continuous material infeed and outfeed is needed. KASTO offers a wide range of roller conveyors and inclined magazines for bar lengths up to 12 metres. As an alternative to inclined magazines, loaders are available for bundles up to a maximum of 5 tonnes. There are also flat and universal magazines for rectangular and profile materials or for fully automatic processing of cutting orders of small to medium batch sizes.

Several possibilities are available for the outfeed side, including conveyors and various types of automated sorting systems.

BlueFire Equipment Corporation announced today its team of scientists and engineers are working to finalize production of custom designed proprietary polycrystalline diamond cutter tungsten carbide (PDC) drill bits for its international clients.

“BlueFire’s team is customizing its highly engineered drilling equipment for very deep, high pressure environments and dense, hard rock formations.”

Using advanced manufacturing techniques, BlueFire is optimizing and adapting its leading edge drill bit technology for international applications.

Chairman and CEO of BlueFire Equipment Corporation William A. Blackwell said, “BlueFire’s team is customizing its highly engineered drilling equipment for very deep, high pressure environments and dense, hard rock formations.” He added, “We are casting these tungsten carbide PDC bits using our company’s advanced manufacturing techniques and made-to-order design specifications. The result is an improved product with the same cost and time saving attributes as our previous designs.”

Over the course of a drilling program, BlueFire’s technology has demonstrated the potential to save operators millions of dollars. As previously announced, the BlueFire PDC bit drilled in excess of 200 feet per hour in the Powder River Basin, demonstrating excellent performance. BlueFire’s proprietary bit drilled more than 6,000 feet at the Campbell County, Wyoming location.

BlueFire’s exclusive design has the ability to provide higher rates of penetration (ROP) and longer bit runs in hard rock formations and shales, representing a breakthrough in drilling technology. BlueFire bits employ large cutter face volumes for rapid drilling of shales, sandstones, limestones and sticky clays. These tungsten carbide drill bits utilize premium PDC cutters for improved ROP and are designed using directed ports to accelerate cleaning and optimize cooling. Company findings indicate a decrease of more than 30 percent in temperature on the cutting surfaces, drastically reducing cutter wear and extending the life of the bit.

Conventional tungsten carbide drill bits use nozzles that eject drilling fluid into the well bottom resulting in a general application and uneven distribution at the point of contact. BlueFire’s bit design employs strategically aligned nozzles to concentrate high-pressure jet streams directly on the cutting edge, lubricating the interface between the cutters and the rock formation being drilled. Furthermore, improved cleaning and scouring action facilitates removal of cuttings. The result is a bit that runs cleaner and cooler.
