Above all, special tools with superhard cutting materials are manufactured and distributed on their own responsibility. These include in particular tools that are equipped with diamond, the hardest material on earth.

The difference is that NEHER does not process natural diamonds, but rather a synthetically produced diamond polycrystalline diamond. But also pCBN-populated polycrystalline cubic boron nitride - second hardest material after diamond and pure carbide tools are produced.

The main customers are the automotive, wood and aerospace industries and mechanical engineering. Customers can thus be supplied with one-stop-shop with leak testing and assembly systems as well as automation solutions upstream or downstream of the machining department. Nevertheless, all the jobs could be saved by the sound foundation on which the company stands.

After this time, steady growth continued. In addition to a doubling of the production area and the ceremonial inauguration of the "exemplary" building in , numerous investments were also made in the latest technologies and machines.

One of the mottos of the managing director Gerd Neher is to have always the newest technologies available, in order to be able to offer the highest quality tool to the customers.

Both different metals as well as numerous plastics are processed with the latest generation 3D printers. Not only tools for personal use are printed, but also customer components as prototypes and in series. In the neighboring state of Mexico, a sales location with several employees was set up at the same time. The product portfolio of Star SU includes mechanical engineering, the production of hobs, solid carbide tools as well as the production of cemented carbide sintered blanks.

The aim of this joint venture is to provide flexible and fast service to customers in North and Central America, primarily from the automotive industry and the aerospace industry. This avoids high transport and bureaucracy costs. In addition, customers benefit from a comprehensive range of tools and the know-how of two specialists in their industry. In the case of mutual visits, which take place at regular intervals, the managers from both companies consult each other in order to further develop and promote the joint project.

The employees from the production of both companies also meet regularly to clarify any questions and to exchange and further develop each other.

Is Diamond Really that Super of a Material? Diamond Materials, Part 1

The fabrication of a superhard diamond tool is the key factor for micro milling of miniature parts made of hard and brittle material. In this paper, the polycrystalline diamond PCD micro end mill is fabricated with three steps. First, the PCD plate is welded on the tool shank with the high-frequency induction welding process. Then, the PCD micro end mill is pre-formed with wire electrical discharge machining to generate its main shape and structure. Finally, the PCD micro end mill is further sharpened with a diamond wheel to improve the tool quality.

In deep-sea or offshore mining for oil and gas, the durability and freedom from maintenance of all deployed machines over timespans of 10 to 30 years is essential. Achieving this is next to impossible with conventional materials — specifically, for example, with regard to wear components in pumps, pipe segments or nozzles.

All activities take place at the JBO production location at Albstadt, ranging from design planning in close cooperation with customers and selection of optimal cutting materials for specific applications to the production on our laser processing machines of the very latest generation. Compared to the conventional methods used to manufacture of tools tipped with cutting materials, the exceptional quality of the super-sharp cutting edge is instantly recognizable. It is characterized by minimal micro chipping and cutting edge rounding.

Diamond tool

A diamond tool is a cutting tool with diamond grains fixed on the functional parts of the tool via a bonding material or another method. As diamond is a superhard material , diamond tools have many advantages as compared with tools made with common abrasives such as corundum and silicon carbide. In Natural History , Pliny wrote "When an adamas is successfully broken it disintegrates into splinters so small as to be scarcely visible. These are much sought after by engravers of gems and are inserted by them into iron tools because they make hollows in the hardest materials without difficulty.

Aug 3, - METALLIC BINDERS FOR DIAMOND TOOL PRODUCTION. Diamond impregnated tools are composite materials with diamonds embedded in a metallic matrix. During cutting operation the behaviour of the hard phase and the metal binder the have to be carefully adjusted to reach the best performance of the tool.

The present invention is a method for producing a powder for diamond tools, and a method for producing a cutting tip using the same, more specifically, a method of mechanically alloying iron powder and metal compound powder, diamond internal performance improved by improving the internal microstructure It relates to a method for producing a powder for diamond tools capable of manufacturing a tool, and a method for producing a cutting tip using the same. In diamond cutting tools, cobalt powder is generally used as a raw material for the sintered body binder of the cutting tip. Such cobalt powder can be widely applied as a raw material powder for diamond cutting tools regardless of the type of work material such as granite, concrete, asphalt, marble, etc. In addition, a cutting tip made of cobalt powder as a raw material easily protrudes diamond particles during cutting to improve cutting efficiency.

Но к концу второй недели заключения основания для оптимизма исчезли и Ричард с Элли приуныли.

Он заручился поддержкой сената и за относительно короткий срок сумел накопить арсенал, способный нанести серьезный ущерб нашей колонии. Верховный Оптимизатор умолкла, тем временем Ричард и Николь разглядывали видеоснимки, на которых были изображены бомбы, базуки и пулеметы, изготовляемые в Новом Эдеме. - Все последние четыре дня небольшие группы людей проводили разведывательные вылазки, им помогала пара геликоптеров.

Разведывательные отряды уже достигли Барьерного леса по всему периметру нашей территории.

Уличные проститутки искали клиентов у дверей одного из клубов. Кэти подошла к одной из женщин, о чем-то недолго поговорила с ней и исчезла из виду. Ричард и Николь отметили, как исхудала и устала их дочь. Они попросили Арчи несколько раз повторить отрывок. Другой был целиком отведен госпиталю в Сентрал-Сити. Без всяких слов было ясно, что там не хватает лекарств, персонала.

Нет. - твердо произнесла. - В этом вопросе я вам не помощница. Кроме того, вы скомпрометировали меня тем, что не сказали правду заранее.
