Drilling deep holes up to 4m
We offer drilling of deep holes from fi10mm to fi150mm, maximum length: 4000 mm. A deep hole is classified on the basis of a depth to diameter ratio of at least 10:1 (at min fi 10mm). Deep hole drilling is used in many industrial applications, but its origin is derived from the need to drill very accurate and straight barrels, where the ratio of depth to diameter can exceed 20:1 and reach 100:1 (with max fi 150mm and length up to 4000mm ).
Knowledge base
Types of filaments produced and used for 3D printing.
The filament is a thermoplastic material that is most often used in the 3D printing process using the FDM melt deposition method. In this printing method, the applied material, which is a thermoplastic plastic, is extruded through a special nozzle of the 3D printer head. The head is heated to a temperature that allows the filament to melt. The printer head regulates the flow of a given thermoplastic and is moved in two axes according to the instructions of the CAM program. Movement in the third axis is provided by the printer bed, which is heated. The model is produced layer by layer until the end of 3D printing. 3D FDM printers mainly use plastics such as: PLA, ABS, PET-G, PVA, nylon, composite of plastic and wood, composite of plastic and gypsum, composite of plastic and metal powders and other materials. Industrial printers and less typical models can use other materials, e.g. resins, rubber.
News
Food processing by extrusion.
Health and nutrition is the most demanding field in this era and will be in the future as well. Extrusion cooking has advantages over other food processing techniques due to its continuous process and high yield. The food extrusion process ensures the retention of nutrients due to the high temperature and short required residence time of the food in the extruder. The influence of the extrusion process on various food ingredients and the links between them are of constant interest to researchers. The use of extrusion to develop nutritionally balanced or fortified foods makes it necessary to study the nutritional value of extruded products.
