      一、車刀種類和用途 車刀是應用更廣的一種單刃刀具。也是學習、分析各類刀具的基礎。 車刀用于各種車床上,加工外圓、內孔、端面、螺紋、車槽等。 車刀按結構可分為整體車刀、焊接車刀、機夾車刀、可轉位車刀和成型車刀。其中可轉位車刀的應用日益廣泛,在車刀中所占比例逐漸增加。

      1、 Types and uses of turning tools turning tools are the most widely used single edge tools. It is also the basis for learning and analyzing all kinds of cutting tools. Turning tools are used on various lathes to process outer circles, inner holes, end faces, threads, grooves, etc. According to the structure, turning tools can be divided into integral turning tools, welding turning tools, machine clamp turning tools, indexable turning tools and forming turning tools. The application of indexable turning tool is becoming more and more extensive, and its proportion in turning tool is gradually increasing.

      二、硬質合金焊接車刀 所謂焊接式車刀,就是在碳鋼刀桿上按刀具幾何角度的要求開出刀槽,用焊料將硬質合金刀片焊接在刀槽內,并按所選擇的幾何參數刃磨后使用的車刀。
      2、 Cemented carbide welding turning tool the so-called welding turning tool is a turning tool that is used after cutting out the groove on the carbon steel tool bar according to the requirements of the geometric angle of the tool, welding the cemented carbide blade in the groove with solder, and grinding according to the selected geometric parameters.

      三、機夾車刀 機夾車刀是采用普通刀片,用機械夾固的方法將刀片夾持在刀桿上使用的車刀。此類刀具有如下特點:(1)刀片不經過高溫焊接,避免了因焊接而引起的刀片硬度下降、產生裂紋等缺陷,提高了刀具的耐用度。 (2)由于刀具耐用度提高,使用時間較長,換刀時間縮短,提高了生產效率。 (3)刀桿可重復使用,既節省了鋼材又提高了刀片的利用率,刀片由制造廠家回收再制,提高了經濟效益,降低了刀具成本。 (4)刀片重磨后,尺寸會逐漸變小,為了恢復刀片的工作位置,往往在車刀結構上設有刀片的調整機構,以增加刀片的重磨次數。 (5)壓緊刀片所用的壓板端部,可以起斷屑器作用。
      3、 Machine clamp turning tool machine clamp turning tool is a turning tool used to clamp the blade on the tool bar by means of mechanical clamping. This kind of cutter has the following characteristics: (1) the blade does not undergo high-temperature welding, which avoids the defects such as the decrease of blade hardness and cracks caused by welding, and improves the durability of the cutter. (2) As the tool durability is improved, the service time is longer, the tool change time is shortened, and the production efficiency is improved. (3) The cutter bar can be reused, which not only saves steel, but also improves the utilization rate of the blade. The blade is recycled and remanufactured by the manufacturer, which improves the economic benefit and reduces the tool cost. (4) After regrinding, the size of the blade will gradually decrease. In order to restore the working position of the blade, an adjustment mechanism of the blade is often set on the turning tool structure to increase the regrinding times of the blade. (5) The end of the pressing plate used to compress the blade can act as a chip breaker.

      四、可轉位車刀 可轉位車刀是使用可轉位刀片的機夾車刀。一條切削刃用鈍后可迅速轉位換成相鄰的新切削刃,即可繼續工作,直到刀片上所有切削刃均已用鈍,刀片才報廢回收。更換新刀片后,車刀又可繼續工作。
      4、 Indexable turning tool indexable turning tool is a machine clamp turning tool using indexable blade. After a cutting edge is blunt, it can be quickly transposed and replaced with an adjacent new cutting edge to continue working. The blade will not be scrapped and recycled until all cutting edges on the blade have been blunt. After replacing the new blade, the turning tool can continue to work.
      .可轉位刀具的優點 與焊接車刀相比,可轉位車刀具有下述優點: (1)刀具壽命高 由于刀片避免了由焊接和刃磨高溫引起的缺陷,刀具幾何參數完全由刀片和刀桿槽保證,切削性能穩定,從而提高了刀具壽命。 (2)生產效率高 由于機床操作工人不再磨刀,可大大減少停機換刀等輔助時間。 (3)有利于推廣新技術、新工藝 可轉位刀有利于推廣使用涂層、陶瓷等新型刀具材料。 (4)有利于降低刀具成本 由于刀桿使用壽命長,大大減少了刀桿的消耗和庫存量,簡化了刀具的管理工作,降低了刀具成本。
      Advantages of indexable tool compared with welding turning tool, indexable turning tool has the following advantages: (1) high tool life. Because the blade avoids the defects caused by welding and grinding high temperature, the geometric parameters of the tool are completely guaranteed by the blade and arbor groove, and the cutting performance is stable, so as to improve the tool life. (2) The production efficiency is high. Because the machine tool operators no longer grind the tool, the auxiliary time such as stopping and changing the tool can be greatly reduced. (3) It is conducive to the promotion of new technologies and processes, indexable knives, and the promotion and use of new tool materials such as coatings and ceramics. (4) It is conducive to reduce the tool cost. Due to the long service life of the tool bar, it greatly reduces the consumption and inventory of the tool bar, simplifies the tool management and reduces the tool cost.
      .可轉位車刀刀片的夾緊特點與要求 (1)定位精度高 刀片轉位或更換新刀片后,刀尖位置的變化應在工件精度允許的范圍內。 (2)刀片夾緊可靠 應保證刀片、刀墊、刀桿接觸面緊密貼合,經得起沖擊和振動,但夾緊力也不宜過大,應力分布應均勻,以免壓碎刀片。 (3)排屑流暢 刀片前面上更好無障礙,保證切屑排出流暢,并容易觀察。 (4) 使用方便 轉換刀刃和更換新刀片方便、迅速。對小尺寸刀具結構要緊湊。 在滿足以上要求時,盡可能使結構簡單,制造和使用方便。
      . clamping characteristics and requirements of indexable turning tool blade (1) high positioning accuracy. After the blade is rotated or replaced with a new blade, the change of tool tip position shall be within the allowable range of workpiece accuracy. (2) The clamping of the blade is reliable. Ensure that the contact surfaces of the blade, knife pad and knife rod are closely fitted and can withstand impact and vibration, but the clamping force should not be too large, and the stress distribution should be uniform to avoid crushing the blade. (3) The chip removal is smooth. The front of the blade should be unobstructed to ensure smooth chip discharge and easy observation. (4) Easy to use, convenient and quick to change the blade and replace the new blade. For small-size tools, the structure should be compact. When meeting the above requirements, make the structure as simple as possible and easy to manufacture and use.
      五、成形車刀 成形車刀是加工回轉體成形表面的專用刀具,其刃形是根據工件廓形設計的,可用在各類車床上加工內外回轉體的成形表面。 用成形車刀加工零件時可一次形成零件表面,操作簡便、生產率高,加工后能達到公差等級IT8~IT10、粗糙度為10~5μm,并能保證較高的互換性。但成形車刀制造較復雜、成本較高,刀刃工作長度較寬,故易引起振動。 成形車刀主要用在加工批量較大的中、小尺寸帶成形表面的零件。
      5、 Forming turning tool forming turning tool is a special tool for machining the formed surface of rotating body. Its blade shape is designed according to the workpiece profile. It can be used to process the formed surface of internal and external rotating bodies on various lathes. When machining parts with forming turning tool, the part surface can be formed at one time, with simple operation and high productivity. After machining, the tolerance grade it8 ~ it10 and roughness 10 ~ 5 can be achieved μ m. And can ensure high interchangeability. However, the manufacturing of forming turning tool is complex, the cost is high, and the working length of blade is wide, so it is easy to cause vibration. Forming turning tools are mainly used to process medium and small-size parts with formed surface in large batches.
      工欲善其事,必先利其器,為了在車床上做良好的切削,正確地準備和使用刀具是很重要的工作。不同的工作需要不同形狀的車刀,切削不同的材料要求刀口具不同的刀角,車刀和工作物的位置和速度應有一定相對的關系,車刀本身也應具備足夠的硬度、強度而且耐磨、耐熱。因此,如何選擇車刀材料,刀具角度之研磨都是重要的考慮因素。
      In order to do good cutting on the lathe, it is very important to correctly prepare and use the cutting tools. Different jobs require different turning tools of different shapes. Cutting different materials requires different cutting edges with different tool angles. The position and speed of the turning tool and the work object should have a certain relative relationship. The turning tool itself should also have sufficient hardness, strength, wear resistance and heat resistance. Therefore, how to select turning tool material and grinding of tool angle are important considerations.
