FIS offers diamond tools and dental instruments

<body bgcolor="#b0c4de" alink="#cc0000" link="navy" vlink="#696969"> Being most experienced in manufacturing diamond tools with electroplated bond we would like to highlight some of our extraordinary products: diamond discs with penetrated rim, the use of natural or synthetic diamond for FG burs and also lab tools with sintered bond.<br> <br> While the standard for FG burs is natural diamond grit, the option - given in some cases - to choose from synthetic diamond is unusual. Our experience and the quality of our bonding systems provide perfect solutions of grinding problems for dental offices as well as for dental labs.<br> <br> Diamond cutting discs with penetrated rim<br> > wide range of dimensions<br> > extremely long lasting<br> > flexible though<br> <br> <p>Natural or synthetic diamond for FG burs<br> > perfect choice for each preparation<br> > smooth surface with synthetic grit<br> <br> <br> Sintered hand piece diamonds<br> > long lasting bond<br> > wide selection of different shapes<br> <br> <br> <br> <b>We have been manufacturing diamond tools for dental as well as diamond and CBN tools for industrial applications for 60 years. Shapes, sizes and abrasive layers of our products are very carefully matched for optimum use in all applications. Custom products have been manufactured for many of our customers. This has resulted in smart solutions which are unparalleled in solving technological requirements, offering high quality products.<br> </b><br> <br> <b><span class="titel_1"> »High-tech is a standard«<br> <br> <br> </span></b>For dental applications, our production ranges from FG burs to plaster trimmer wheels. We manufacture our FG diamonds in varying grit sizes between 504 and 554 (acc. to ISO standards), with choice of one of two types of grit: natural and/or synthetic (S) diamond (limited to certain sizes and types).<br> <br> <br> The natural diamond crystals typically have an irregular shape and sharp cutting edges which ensure a quick material removal. Layers containing the blocktype, synthetic diamond crystals provide a professional preparation with less surface roughness. Those FG diamonds have a black coating to increase the optical contrast between layer and tooth. Only hardened, stainless chromium/nickel steels are used as basic material for the fis diamond tools (except a few cutting discs). The tolerances of the shaft diameters not only meet the requirements of the ISO standard, but exceed them. With quality in mind, we grind the shafts to close tolerances for precise fit in the handpiece chuck which minimizes runout error and protects the chuck. In addition, we have introduced a new generation of diamonds (HighQPlus). These multilayer FG tools provide long life in rough cutting applications.<br> <br> <br> <br> The following instructions provide best results in preparations through careful handling of the diamond instruments and their application. Consideration of the teeth as well as perfect hygenic conditions are the main concern.<br>  New instruments must be sterilized before first use.<br>  Instruments are to be selected by the head diameter to prevent from damaging neighbour teeth or tissue.<br>  Rounded shapes should be favoured.<br>  Instruments with coarse grit are not always indicated; usually they require a finish grinding operation.<br>  Trays or original packing should be used for storing.<br>  The shafts have to be secured properly and checked for minimum runout before use.<br>  The burs should be set to the working speed according to the graphical diagram. It should be set before applying the bur to the object.<br>  Spray cooling with a minimum flow of 50 ml/min must be provided. Additional cooling is required as burs longer than 21 mm or heads bigger than 2 mm are being used.<br> <br>  Forces should not exceed 2 N (appr. 200 p). Higher forces do not result in a quicker material removal, but increase the thermal load on the tooth.<br> <br> <br> <span class="absatz">Tools with sintered bond <br> </span> Worn or damaged burs must be replaced immediately.<br> <br> Our tools with sintered bond are particularly suitable for processing ceramic materials and metal bondings. The high degree dimensional stability and the long service life are ensured by a special production technique.<br> <br>  Burs should be cleaned in a cleaning solution first after use. See manufacturers instructions for details.<br>  Burs can be brushed to remove material sticking to the diamond layer.<br>  Dental diamond instruments are made of stainless materials. However, they must not get in contact with acids.<br>  Max. sterilizing temperature: 1500 C.<br> <br> <b><span class="absatz">Directions for use of rotary diamond instruments </span><br> <span class="absatz">(Lab tools with sintered bond)</span><br> </b><br>  The tools should be set to the working speed according to the graphical diagram.<br>  A slightly oscillating motion provides low cutting forces by a short length of contact.<br>  Forces should be kept low to avoid heating and excessive tool wear.<br>  Cutting discs with sintered bond can break easily due to the brittle structure of the material and should not be bent.<br> Tools with diamond grit in a sintered bond offer a variety of applications combined with a long tool life. Some simple rules ensure maximum use of their advantages.<br> <br>  A soft cleaning stone is recommended for the cleaning of tools with sintered bond. This procedure will remove the top layer of the bond and release unused diamond grit.<br> <br> <span class="absatz"><b>Cutting discs - with penetrated rim<br> </b></span><br> In addition to proven cutting discs with surface layer for all grinding and cutting operations, we are the only manufacturer of cutting discs with penetrated rim covering the diameter range from 10 to 150 mm. This layer is - similar to a sintered bond - completely penetrated with diamond crystals. The discs allow thinnest cuts and extremely long service. They are constantly flexible and appropriate for technicians during cutting and lateral grinding of ceramics, porcelain, plaster and metals.<br> <br> <br> <span class="absatz"><b>Directions for use of rotary diamond discs with penetrated rim<br> (Lab tools with electroplated bond, dispersed, Fig. 354).<br> </b></span><br>  The tools should be set to the working speed according to the graphical diagram.<br>  Cutting discs with penetrated rim are designed for separating. An oscillating motion should be applied while moving in radial direction.<br>  Although these discs are flexible, lateral grinding should be performed at very low forces only. High lateral forces may result in breakage, as the thickness of the blade usually is only 0,12 mm.<br> Cutting discs with electroplated bond and penetrated rim provide unique properties. Other than discs with a single layer, this type achieves a very long life time by a specific multilayer design. Though they are thin and flexible, much more than the ones with sintered bond. They surpass all other types of discs when handled properly.<br>  Bending or turning when cutting into a slot must be avoided.<br>  A soft cleaning stone is recommended for the cleaning of tools with sintered bond. This procedure will remove the top layer of the bond and release unused diamond grit.<br> <br> <span class="absatz"><b>Natural diamond - synthetic diamond<br> <br> </b></span>We manufacture our FG tools in varying grit sizes between 504 and 554 (acc. to ISO standards), with choice of one of two types of grit: natural and/or synthetic (S) diamond (limited to certain sizes and types).
