因為過程安全是醫(yī)療技術的關鍵
牙科技術中的新材料為高要求的任務提供了工具。因為在醫(yī)療過程中,即使使用難以加工的材料,也必須始終保證安全性和準確性。
在醫(yī)療技術領域,對工具組件的要求尤其復雜。微創(chuàng)手術和納米技術材料開發(fā)等新的治療方法總是需要新的創(chuàng)新。
例如,現(xiàn)在越來越多的材料被用于牙科植入物,但這些材料也越來越難以切割,在這些最具挑戰(zhàn)性的應用中,可以使用穩(wěn)定的熱穩(wěn)定性和恒定的橫向斷裂強度。我們的碳化鎢已經(jīng)顯著延長了牙科技術中使用的加工工具的使用壽命。
義齒應該感覺自然,同時保證最高水平的功能。一種名為氧化鋯的高性能陶瓷能夠滿足這些要求。這種材料被認為是相當于鋼的陶瓷,具有高斷裂韌性、橫向斷裂和拉伸強度。現(xiàn)在,由于材料的耐磨性,氧化鋯對相關機床提出了重大挑戰(zhàn)。為了使加工更加經(jīng)濟,開發(fā)了由碳化鎢制成的特殊銑刀,其特點是具有最佳的幾何形狀和特殊的金剛石涂層。
通過與客戶的密切合作,我們開發(fā)出了一種非常適合金剛石涂層的碳化物。少量額外的碳化物和優(yōu)化的鈷含量確保了粘合強度。顆粒尺寸的選擇使金剛石層能夠牢固地固定在基底上。
Because process safety is the essential thing in medical technology
New materials in dental technology provide tools for demanding tasks. Because safety and accuracy must always be guaranteed during a medical procedure – even with materials that are difficult to machine.
In the field of medical technology, the requirements for tool components are particularly complex. New treatments such as minimally invasive surgery and material developments in nanotechnology always require new innovations.
For example, more materials are now being used for dental implants, but these are also increasingly more difficult to cut. Only an excellent tungsten carbide with an exceptionally even structure, consistent thermal stability and a constant transverse rupture strength may be used in these most challenging applications. Our tungsten carbide has already significantly extended the service life of machining tools used in dental technology.
Dentures should feel natural while guaranteeing the highest level of functionality. A high-performance ceramic called zirconium oxide has been able to meet these requirements. The material is considered to be the ceramic equivalent of steel, with a high fracture toughness and transverse rupture and tensile strength. Now, due to the abrasiveness of the material, zirconium oxide is presenting major challenges for the associated machine tools. To make machining more economical, special milling tools made of tungsten carbide have been developed, characterized by optimal geometries and special diamond coatings.
Working in close cooperation with our customers, we have developed a carbide that is outstandingly well-suited to diamond coating. Adhesion strength is ensured by a small number of additional carbides and optimized cobalt content. The selection of particle size allows the diamond layer to securely anchor the substrate.
