【正文】 三槽端銑刀的中心部分為直徑的56%，四槽或者槽數(shù)更多的端銑刀的中心部分為直徑的61%。TiCN涂層可加工所有材料。硬質(zhì)合金鉆頭必須首先從刀尖開始切削，然后再使用外切削邊。某個切削邊磨損后，您可分度至另一個切削邊，在所有切削邊都已用過之后，只需更換嵌齒，而非整個刀具。在選擇刀具時，刀具材料是最重要的考慮因素。在計算切削所需功率時，必須輸入RPM，進給速度，槽數(shù)，切削深度，切削寬度并從菜單中選擇某一材料。提示：嵌齒端銑刀用于在更高速度下切削硬質(zhì)合金之外的金屬。圓鼻端銑刀的半徑在切入工件時更為緩和。使用刀具補償功能可調(diào)節(jié)原料的切削量。在盲孔攻絲時，必須盡可能鉆至最大深度，以免在絲錐下方擠壓切屑。絲錐絲錐用于在鉆孔內(nèi)加工螺紋。首先應鉆孔，然后由擴孔鉆清除。用于加工小徑孔，孔壁帶有錐度。通常，工程圖紙上都會規(guī)定某個鉆孔需要鉆至“外徑深度”。s diameter. This gives the tool a spherical shape at the tip. It can be used to cut with side of the tool like an end mill. TIP: The primary purpose of a ball end mill is to machine lofted surfaces. The spherical shape of the tool is able to move along any undulating surface and cut anywhere along the cutter39。英文原文CUTTING TOOLS When selecting cutting tools for a job, the first thing to consider is what type of operation needs to be performed. Here is a quick description of the basic cutting tools most often used in milling operations. DRILL A drill is used to create a round, cylindrical hole in a workpiece. Drilled holes can be through holes or blind holes.s ball end. As a ball can roll over a surface, a ball end mill can be used to cut any such surface. INSERT END MILLAn insert end mill is the same as a standard end mill but with replaceable carbide inserts. TIP: Insert end mills are designed to remove metal at higher rates than solid carbide. They e in a large range of diameters and are able to cut at a deeper depth of cut. This is fantastic but, when using these cutters, it is a good idea to calculate the horsepower required to make a cut. Piece of cake on your Haas control: There is a button on the front labeled HELP/CALC. Press this button once to get the Help menu, press it again to get the Calculator functions. Use the PAGE UP/PAGE DOWN keys to scroll between three pages: Trigonometry Help, Circular Interpolation Help, and Milling Help. Each one of these pages has a simple calculator in the upper left hand corner. On the Milling Help page, you can solve three equations:1. SFM = (cutter diameter [in.]) * RPM * / 12 2. (Chip load [in.]) = (feed [in. per min.]) / RPM / of flutes 3. (Feed [in. per min.]) = RPM / (thread pitch) With all three equations, you may enter all but one of the values and the control will pute and display the remaining value. To calculate the horsepower required for a cut, you must enter values for RPM, feed rate, number of flutes, depth of cut, width of cut, and choose a material from the menu. If you change any of the above values, the calculator will automatically update the required horsepower for the cut you intend. The next thing to consider when choosing cutting tools for a job is what material you are going to cut. The most mon materials cut in the metalworking industry can be divided into two categories: nonferrous and ferrous. Nonferrous materials include aluminum and aluminum alloys, copper and copper alloys, magnesium alloys, nickel and nickel alloys, titanium and titanium alloys. Common ferrous materials include carbon steel, alloy steel, stainless steel, tool steel, and ferrous cast metals like iron. Nonferrous metals are softer and easier to cut, with the exception of nickel and titanium.
