GUHRING - THE TOOL COMPANY

Carbides

For the last 15 years Guhring has developed and produced its own carbide in two plants espacially for the precision tool industry but increasingly also for various applications not related to cutting operations, as for example in the mining and civil engineering industry, recycling industry, consumer industry etc. This enables us to adapt the tool materials for our own carbide tools to always optimally correspond to the newest requirements.

Today, with an annual production of 1,500 tons, Guhring is one of the largest carbide producers. The product range starts with a simple 1,2 mm diameter round bar extending up to isostatic pressed rolling rolls of 360 mm diameter

The quality of our products is our first and absolute priority. Every customer production order is automatically subjected to a metallurgical inspection prior to release. For example, samples are RFA analysed, ground sections of speciments are produced, physical data is gathered and documented. All the data is filed and can be accessed as and when required.
With carbide rod blanks a one hundred percent inspection for roundness, with IC a spiral angle inspection, are all part of our quality standard. In addition, we inspect the complete rod for possible error spots in the structure.
In the sector for costumer special carbide parts shrinkage inspections ensure that the final product satisfies the costumer's requirements.

Guhring now offers carbide grades with qualities that meet the highest expectations. In Berlin, we have a highly specialized facility for the production of carbide. We use the most modern equipment such as cold isostatic wetbag and drybag presses, or presses equipped with press controls in our production of carbide tooling blanks. We manufacture routinely complex forms and geometries to drawing. Almost unique in the production of various grades of carbide is the centralized programming of CNC machines which is particularly advantageous when forming parts to drawing. The sintering facility is exclusively equipped with sinter HIP furnaces computer-controlled by a central command station. The furnace processes guarantee the highest homogenity and strenght. Our laboratories are provided with the most advanced facilities, such as: - light optics metallography - electron microscopy - X-ray fluorescent analysis - X-ray diffractometry - mechanical testing equipment - magnetic measuring methods The flexibility of our well-equipped tool-room enables us to satisfy the most exacting and unusual ccostumer requirements.

Special parts for the forming industry - excellent durability -
Tools for the cold forming of metals must be wear-resistant, hard and tough at the same time - an ideal application range for carbide. It can withstand the high mechanical and thermal stresses thar occur during the plastic deformation of the metal to be machined. For example, drawing punches are available in different carbide grades for the production of tins and cans in the food and drinks industry. In contrast, Guhring carbide cold heading dies are applied for the production of screws. Drawing dies available in different carbide grades withstand the demands put upon them during the pressing and drawing in the forming process of steel and non-ferrous metals. In addition, Guhring also supplies carbide ribbed rolls, cold and smoothing rolls, mandrels and coining dies for the forming industry. During the development of special carbide parts Guhring is an experienced partner at the side of the costumer. This also includes advice regarding the application possibilities of carbide as well as the preparation of a comprehensive documentation in respect of each component.

Special parts for the cutting tool industry - razorsharp -
In the carbide sector, Guhring is breaking with tradition: Here the cutting tool specialist is now offering tools that do not rotate. Subsequently, Guhring also supplies gear cutters that are required for the production of spiral gears. A further product in the carbide cutting technology are gear hobbing mill blanks that are applied in the production of straight tooth gears. Principal customers are transmission builders. Thanks to state-of-the-art analysing methods, Guhring produces special parts of the highest quality. X-ray-fluorescense-analysis, roundness inspections and shrinkage inspections guarantee that the raw material and the end product comply with the required customer specifications one hundred percent. In order to achieve these results, the carbide division invests considerable time and money.

Special parts for the wear protection industry - completely wear resistant -
Everywhere, where large quantities of raw materials and also finished goods flow at fast speeds along conveyor belts or through machines, there is an exposure to extreme wear on the running surfaces or in the guide rails. This even applies to relatively soft and light products such as food and consumer goods as well as plastic granules used for the production of cling film. Carbide possesses the required resistance to abrasion in order to combat this type of wear and ensures that the machines and equipment operate for longer. In the food production industry this abrasion resistance furthermore prevents the ingress of impurities caused by wear into the foodchain. Therefore, Guhring provides strips, guide rails, form liners, pressure plates, grooved bushes and wear protection components and the like for a multitude of applications. Patented production processes and state-of-the-art production facilities make it possible for Guhring's carbide division to produce customer specific special parts of the highest quality and within a short time period. Perfect tolerances and optimal efficiency for the individual application are the advantages for the customer thanks to these investments. Click here to request a catalogue.
