Hardware processing - dry machining - high-speed machining

Is to promote, the use of the split mold Arts before the most essential aspects of rhino l fog. Perhaps half of the sets depends on the success of listless machine tools, technical data and a quarter depending on the appropriate tool material, and the user experience in production also accounted for a quarter. In particular, in the car on the bed of the HRC (Rockwell hardness) is 58 ~ 62, finishing a hard material formed the focus of discussion. Bachelor of Engineering, University of Hanover, according to J. IFw Schmidt introduced the hard way has the advantage of finishing processes: In addition to renounce the use of cooling and lubrication to be associated with this and with the economic and ecological advantages, but mainly it instead of grinding method. Typically, the grinding process of the shortcomings of the processing time and alignment of long hours, often very complex process sequence, which leads to increased processing costs. Meaningful is. Seems to be when the complex parts to be machined, the geometry have to use such a tool must work hard pumping, head for the introduction of hard machining of complex parts only - the second fixture will be able to complete all of its processing. One. Before using the hard process, first selecting the appropriate tools. Because of dimensional tolerances, form tolerances and surface tolerance requirements are very high, so the choice of tools to achieve process quality and quality of the workpiece plays a decisive impact. Therefore, the machine should be used in a high dynamic stiffness and static stiffness, high shock resistance,[link widoczny dla zalogowanych], thermal stability, high precision geometry and kinematics accuracy to meet these requirements, the use of hydrostatic bearing structure, high-precision linear displacement measurement system or temperature control is helpful headstock. After the selected machine. We should note that the appropriate choice of tool materials and proper data. In addition to ceramic tool, the most suitable tool material should be most important PKB (polycrystalline boron nitride). According to the company BEng J. Cerasiv Schneider Doll's introduction, the following shall be original shell-line options; when the intermittent cutting,[link widoczny dla zalogowanych], roughing and impact loads should be more advantageous to use polycrystalline boron nitride; if the processing and finishing precision cutting,[link widoczny dla zalogowanych], mixing should be used PKB as polycrystalline boron nitride ceramic is widely used, so the outlook is excellent. However, to bring attention to that, although there are many PKB world supplier, but the PKB was only six production plants, none of which are European. For this reason, users of PKB application tool material evaluation and selection of hunting ability is particularly difficult. In this regard, MRsubischl Carbide Corporation BEng G. Grossman remind you to be considered. But the mainstream is the CBN (cubic boron nitride) grain size is moderate, sticky station agent particle size is moderate, A Brighter Summer Day Results CBN crystal phase composition and the characteristics of the experience of blade production in terms of the different performance of different brands are responsible The. In addition, the blade geometry and blade surface welding technology has huge potential for performance. Ceramic tool materials and PKB both the process parameters similar to the range of cutting speed Vc in the 12O ~ 25Om/rain, take the knife is the amount of the range of f 0. O8 ~ O. 1fimm / teeth. Workpiece machining accuracy can be achieved: the surface roughness R. 1 a ~ 3, um,[link widoczny dla zalogowanych], roundness tolerance IT 5 to 7. According to Dr. G. Ford Engineering Hope's experience in the production of gear transmission processing on the processing thread Queensland buckle and sliding surface bearing hole processing questions should be deemed to have been resolved. On the contrary, needle roller bearing cone and the synchronization process there are some difficult holes, but can be attached to a short stroke honing head to overcome. Then attached by a short way from the first stroke honing grinding precision turning into a hard, it has been in the investment cost of more than 50 potential. But also shorten the production cycle. So. Only 5 CNC lathes to replace 11 grinder. In general, this will help to eliminate the use of experts to discuss the hard finishing process concerns, such concerns are experts fear the impact on the processing surface layer is often encountered Ya, see Fig. The impact on the surface layer of the tool is directly related to the increase in passive force. But this can not be replaced large knives and cross feed and feed content to avoid. In contrast, repeated high speed on the surface by the impact of not grams. - Processing I. C $ 5 (HRC60 ~ 62) calculated the surface layer of the map: processing parameters: 1000m/min, f0.1ram, ap0.2mm, Vbco / lm; FpI10N, Fe80N ・ FfSON ・ surface stress 100MPa Below: processing parameters: V. 5Ore/rain, f0.1ram, ap0.
