    數控刀具和普通刀具有哪些不一樣?

    (1)高精度的制造質量

    (1) High precision manufacturing quality
    為穩定加工出高精度的零件表面,因而對刀具(包括刀具零件)制造在精度、表面粗糙度、形位公差等方面提出了比普通刀具更嚴格的要求,特別是可轉位刀具,為確保刀片刀尖(切削刃)在轉位后尺寸的重復精度,刀體刀槽和定位零件等關鍵部位的尺寸和精度、表面粗糙度須嚴格給予保證,同時為便于刀具在對刀儀的對刀和尺寸測量,基面加工精度也應保證。
    In order to stably process the high-precision part surface, more stringent requirements are put forward for the manufacturing of tools (including tool parts) in terms of accuracy, surface roughness and geometric tolerance than ordinary tools, especially indexable tools. In order to ensure the repeated accuracy of the size of the blade tip (cutting edge) after rotation, the size and accuracy of key parts such as tool body, groove and positioning parts The surface roughness must be strictly guaranteed. At the same time, in order to facilitate the tool setting and dimension measurement of the tool in the tool setting instrument, the machining accuracy of the base surface should also be guaranteed.
    (2)刀具結構的優化
    (2) Optimization of tool structure
    先進的刀具結構能大大提高切削效率,如高速鋼數控銑削刀具在結構上已較多采用波形刃和大螺旋角結構,硬質合金可轉位刀具則采用了內冷卻、刀片立裝式、模塊可換和可調式結構,而如內冷卻結構,則是一般普通機床無法應用的。
    The advanced tool structure can greatly improve the cutting efficiency. For example, the structure of high-speed steel NC milling tools has mostly adopted the wave edge and large spiral angle structure, while the cemented carbide indexable tools adopt the internal cooling, blade vertical installation, module replaceable and adjustable structure, while the internal cooling structure is not applicable to ordinary machine tools.
    (3)刀具高品質材料的廣泛應用
    (3) Wide application of cutting tools and high quality materials
    為延長刀具使用壽命,提高刀具強度,很多數控刀具的刀體材料都采用了高強度合金鋼,并進行熱處理(如氮化等表面處理),使其能適用于大切削用量,且刀具壽命也得以顯著提高(普通刀具一般采用的是經過調質處理的中碳鋼)。在刀具刃部材料上,數控刀具則更多選用了各種新牌號的硬質合金(細顆?;虺氼w粒)和超硬刀具材料。
    In order to prolong the tool life and improve the tool strength, the tool body materials of many NC tools are made of high-strength alloy steel and heat treated (such as nitriding and other surface treatment), so that they can be suitable for large cutting parameters, and the tool life can be significantly improved (ordinary tools generally use medium carbon steel after quenching and tempering treatment). In the cutting edge materials, CNC cutting tools use more new brands of cemented carbide (fine particles or ultra-fine particles) and superhard cutting tool materials.

    (4)合理斷屑槽的選用
    (4) Reasonable selection of chip breaking groove
    數控機床上應用的刀具對斷屑槽有嚴格的要求。加工時,刀具不斷屑則機床無法正常工作(有些數控機床、切削是在封閉的狀態下進行),因此不論數控車、銑、鉆或鏜床,刀片都優選了針對不同加工材料和工序的合理斷屑槽型,使切削時能穩定斷屑。
    The cutting tools used in NC machine tools have strict requirements for chip breaking groove. During machining, if the cutting tool keeps chipping, the machine tool cannot work normally (some NC machine tools and cutting are carried out in a closed state). Therefore, whether NC lathe, milling, drilling or boring machine, the blade is optimized with a reasonable chip breaking groove type for different machining materials and processes, so that chip breaking can be stable during cutting.
    (5)刀具(刀片)表面的涂層處理
    (5) Coating treatment of tool (blade) surface
    刀具(刀片)表面涂層技術的出現和發展主要因數控刀具的出現和發展而生。由于涂層能顯著提高刀具硬度、減小摩擦、提高切削效率和使用壽命,所以在各類硬質合金可轉位數控刀具的大部分以上都采用了涂層技術。涂層后的硬質合金刀片還可進行干切削,這也為保護環境實現綠色切削創造了有利條件。
    The emergence and development of tool (blade) surface coating technology is mainly due to the emergence and development of NC tools. Because coating can significantly improve tool hardness, reduce friction, improve cutting efficiency and service life, coating technology is adopted in most of all kinds of cemented carbide indexable NC tools. The coated cemented carbide blade can also carry out dry cutting, which also creates favorable conditions for protecting the environment and realizing green cutting.
