"That was on one of our standard KASTOtec AC5 machines, designed for cutting with tungsten carbide-tipped (TCT) blades. We also make a high-performance KPC variant that incorporates two spring-loaded tensioners to guide the tungsten carbide tipped blade on the return side. This suppresses vibration even more, enabling an increase in production of between 15 and 30%, as well as extending blade life further.

Two new members of the family management team visited customers in the UK during December 2013. Stephanie and Jonathan Riegel saw the company's sawing machines and automated industrial warehouses in action in manufacturing and stockholding facilities from Yorkshire down to Birmingham and across to Cambridgeshire. They were accompanied by Ernst Wagner, managing director of Kasto's subsidiary in Milton Keynes.

The couple recently joined the board of Kasto group, along with Nicole and Sönke Krebber, also sixth-generation members, and Ruth Stolzer, wife of sole managing partner Armin Stolzer, who has run the company for the past 25 years. Dieter Heyl is the director in charge of production and Valentin Meier heads design and R&D.

Turnover at the German parent company remained stable at around €100 million, only slightly lower than in 2012 when one very large order for an automated warehouse was taken from the Bavarian uPVC window and door manufacturer Rehau. Business is increasing in many parts of the world, notably Australia, China, Singapore and Egypt. The number of employees is unchanged at 600, 10% of whom are apprentices, reflecting the policy of many German mittelstand manufacturing companies (medium sized, typically privately owned firms).

The group's global storage system deliveries continue to be around twice the value of its sawing machines sales. In the UK, Kasto has delivered six big automated warehouses in the last decade, plus around 20 smaller storage systems.

However, Mr Wagner says Britain needs to avoid falling behind other industrialised nations when it comes to automation. More than 1,400 Kasto automatic storage and retrieval systems for long stock and sheet have been sold around the world, but only a tiny fraction of these are in the UK.

Another indication of the reticence of British firms to embrace automation, he offers, is the slow acceptance of robotics associated with sawing systems. There are hardly any examples in the UK at the moment, whereas in Germany, central Europe and the USA in particular, such systems are used widely for sorting cut pieces, deburring, feeding material to machine tools, and more.

The company's top-end KASTOtec bandsaws are the main driver for growth on the sawing side of the business, with the message that such machines lower cost per cut as a result of their very high performance via tungsten carbide tipped blades. In 2013, however, the issue of minimising vibration has come to the fore, Mr Wagner says.

Vibration reduces tool life and also that of the machine, lowers productivity, raises noise levels and negatively impacts accuracy and surface finish. So now when Mr Wagner is asked by potential customers why they should buy Kasto bandsaws, he points towards the many features of the company's saws that help to minimise vibration, increasing output and reducing customers' ongoing expenditure on tooling.

"Obviously everyone says that they make a rigid machine, but we were able to prove the superiority of Kasto's bandsaws and vibration management recently during comparative trials carried out for a stockholder.

"Using identical feeds and speeds to those on a competitor's bandsaw when cutting 305 mm diameter Inconel, we achieved 55% higher output and three times the tungsten carbide blade life.

The Penumbra mine is an underground coal mine in South Africa. The company has been struggling with its so-called continuous miners sections. Continuous mining utilizes a Continuous Miner Machine with a large rotating steel drum equipped with tungsten carbide teeth that scrape coal from the seam. Conveyors transport the removed coal from the seam.

Continental Coal Ltd Wednesday said it is still trying to complete a recapitalization that will allow it to settle its convertible notes that mature between November of last year and February of this year, but so far hasn't been able to reach a deal and it warned it may have to appoint administrators.

By a News Reporter-Staff News Editor at Journal of Technology -- Investigators discuss new findings in Tungsten Carbide Coatings Technology. According to news reporting originating from Dortmund, Germany, by VerticalNews correspondents, research stated, "The phenomenon of glass-to-mold sticking is a major problem for industrial glass forming processes. Ternary TiAIN coatings attracted considerable industrial interest because of their excellent tribological performance and high oxidation resistance at high temperatures."

Our news editors obtained a quote from the research from Technical University, "Recently, multicomponent CrAlSiN and TiAISIN coatings have been developed in order to gain high hardness and good thermal stability at temperatures exceeding 800 degrees C. In this study, CrAlSiN, TiAlSiN and AlTiN coatings were deposited on tungsten carbide substrates by using a cathodic-arc deposition system with lateral rotating arc cathodes. Titanium, chromium and AlSi (12 at.% of Si) cathodes were used for the deposition of CrAlSiN and TiAlSiN coatings. All the deposited CrAlSiN, TiAlSiN and AlTiN coatings showed a B1-NaCl crystal structure. The deposited CrAlSiN and TiAlSiN coatings exhibited nanocrystalline structure and possessed hardness as high as 35-37 GPa after annealing at 700 degrees C in air. The wettability of the CrAlSiN, TiAlSiN and AlTiN coated tungsten carbides by molten glass at temperatures between 300 degrees C and 700 degrees C in controlled air under 1.6 Pa was measured by using an improved sessile drop method."

According to the news editors, the research concluded: "The CrAlSiN showed a low oxidation rate and a non-wetting characteristic superior to TiAlSiN and AlTiN coatings."
