Hughes Pumps blast away the abrasives

Hughes Pumps has recently supplied a custom designed, automatic high- pressure tank cleaning system to Sandvik Hard Materials for use at their Coventry Cemented Carbide production facility.

Rigorous control is necessary throughout the Cemented Carbide manufacturing process since the quality of the final product can be greatly affected by seemingly insignificant factors. During manufacture the carbide slurry is dried by spray drying to a powder form. Afterwards the spray dryer vessel must be thoroughly cleaned to remove any remaining deposits and prevent contamination between batches of different material grades. Initially production personnel carried out this function, being lowering into the vessel to use hand held cleaning lances, which proved to be both time consuming and potentially unsafe.

The Hughes turnkey system solution comprises a high pressure pumpset, high pressure stainless steel ring main, with an automatic three dimensional cleaning head that is raised and lowered into the vessel via a high pressure hose and pneumatic hose reel. The tank cleaning head rotates in two planes by the reaction of the water jets to bring about total cleaning coverage of the complete vessel in 30-60 minutes depending on the degree of deposits present.

The cleaning process, which is now totally automated, has proved to be very cost-effective. The complete surface of the vessel is cleaned during the cycle, which has eliminated the possibility of contamination between batches, greatly improving product quality.

Iscar Manufactures a range of Sintered Carbide Inserts for Various Applications

BHI had in the meantime added a number of other leading cemented carbide producers to the IMC stable: notably Ingersoll (USA), Metaldur (Switzerland), Microtools (Israel), Outiltec (France), UOP Spa (Italy), TaeguTec (Korea) and Tungaloy (Japan). Today the IMC group has over 10,000 employees in 140 subsidiaries in 61 countries.
In May 2013 Berkshire Hathaway purchased the remaining 20% shareholding in Iscar for a quoted $2.05 billion giving the Israeli company a total valuation of around $10 billion. "Since the time IMC entered our lives, my partner Charlie Munger and I have enjoyed Berkshire's association with the company, the Wertheimer family and the company's management team," stated Buffett at BHI headquarters in Omaha, Nebraska.
"As you can surmise from the price we're paying for the remaining interest, IMC has enjoyed very significant growth over the last seven years, and we are delighted to acquire the portion of the company that was retained by the Wertheimer family when IMC first became a member of the Berkshire group of companies.

We look forward to continuing our stewardship of this unique company founded by the Wertheimer family in Israel 60 years ago and nurtured into a truly global enterprise," Buffett said in the statement.

Eitan Wertheimer stated, "We are very pleased that IMC has found a permanent home in Berkshire Hathaway, which fully appreciates the unique nature of the global Israeli enterprise that we have created and that is committed to remaining true to that heritage in every way, building on and continuing our historic success and special culture. The growth experienced by IMC since the 2006 Berkshire transaction validates the faith that Warren [Buffett] and Charlie [Munger] showed in our business and the special people in Tefen, Israel and around the world who have made our success possible."

Five Star Tool Introduces a Paradigm Shift in CNC Carbide Cutting Tools Manufacturing

Five Star Tool, has built a reputation for making exceptional custom CNC carbide cutting tools and is now saving manufacturing companies thousands by re-sharpening their used carbide cutting tools. Utilizing cutting edge software and carbide coatings, Five Star Tool is now able to increase the life expectancy of standard tungsten carbide cutting tools by 5 times over the original manufacturer recommendations. This Five Star Tool’s Edgemaster resharpening program is designed to provide CNC manufacturing companies an “Edge” over their competition.

Traditional CNC manufacturing companies typically dispose of used worn out carbide cutting tools costing them hundreds of dollars to replace. The innovative recycling process is designed to handle all types of cutting tools including Profile Cutters - Ball End Mills - Carbide End Mills - Variable Lead/Helix End Mills Center Drills – Centers - Corner Rounding End Mills – Counterbores - Countersinks Key Cutters - Milling Centers - Taper Shank Drills - Roughing End Mills - Saws Carbide/HSS - Spade Blades - Spade Drills - Spot Drills - Step Drills - Taper Ball End Mills - Taper End Mills - H.S.S. End Mills Crest Cut End Mills. Recycling these used cutting tools is now helping manufacturing companies save over 60% in their manufacturing process.

Once the carbide cutting tools arrive to the Rochester, NY recycling center they are sorted, processed and labeled. They are then returned to the customer in specially designed foam containers after passing a carefully inspection. Remarkably, this complete process is guaranteed to be completed within 10 days from arrival.

Five Star Tool is a privately-held, certified leader distributing solid carbide cutting tools throughout the United State for the aerospace, medical, and automotive industries.

Berkshire Hathaway buys remaining stake in Iscar as earnings soar in first half of 2013

Warren Buffett’s Berkshire Hathaway Inc. (BHI) reported net earnings attributable to Berkshire shareholders of $9.433 billion in the first half of 2013, a 48% increase compared with the same period last year. BHI owns a number of diverse businesses including insurance, freight rail transportation, utilities and energy, finance, services and retailing, and manufacturing. The manufacturing arm of the company includes IMC International Metalworking Companies (Iscar), an industry leader in the field of cemented carbide (hardmetal) metal cutting tools. BHI chairman is billionaire Warren E Buffet with Charles T Munger acting as vice-chairman.
Investment in the cemented carbide sector

Warren Buffett made the decision to invest in the metal cutting tool sector seven years ago when BHI bought 80% of IMC (Iscar) for around $5 billion from the Wertheimer family which founded the business in Israel 60 years ago. It was the first acquisition by BHI outside of the United States. The Israeli carbide producer based in Tefen, northern Israel, soon made positive contributions to BHI financial results. Although IMC is not obliged to make public its financial results, it is estimated to have achieved sales of more than $3 billion in 2011 with profits close to $1 billion, more than twice what they were in 2005.

Exote Designed New Metal As Hard As WC-Co Tungsten Carbide

The new material possesses excellent bullet-proofing qualities, and ballistic tests has proved its unequalled ability to stop armour-piercing bullets, according to Exote.

Exote says that the new material is as ecological alternative as WC-Co tungsten carbide, which contains tungsten carbide and cobalt, both of which are defined by the EU as critical.

The material withstands high temperatures and has high-level strength and durability, Exote claims. The metal is ideal for the manufacture of crusher blades and shear cutters, as well as exacting product tools. In ballistic protection it can be used for both personal and vehicle protection.

VTT and Exote Ltd have carried out further development on the material Exote has in production through the use of nano additives, which enable changing its toughness and hardness according to intended use.
