1、Tool Purpose Upon completion of this unit, students will be able to: * Rough and explain the difference between finishing. * Choose the appropriate tool for roughing or finishing of special materials and processing. * Recognition Tool Cutting part of the standard elements and perspective. * The righ
2、t to protect the cutter blade. * List of three most widely used tool material. * Description of each of the most widely used knives made of the material and its processing of Applications. * Space and inclination to understand the definition. * Grinding different tools, plus the principle of space a
3、nd inclination. * To identify different forms of space and the inclination to choose the application of each form. The main points of knowledge: Rough-finished alloy steel casting material Scattered surplus carbide ceramic materials (junction of the oxide) Tool With a chip breaking the surface rough

Kok) Grinding carbon tool steel front-fast finishing horn of rigid steel Double or multiple-side flank before the dip angle obliq
5、ue angle Surface-radius Slice root for curling Rough and finishing tool Cutting speed only in the surface roughness not required when it is not important. Rough the most important thing is to remove the excess material scattered. Only in surface roughness of the finishing time is important. Unlike r
6、ough, finishing the slow processing speed. Chip off with the D-knives, better than the standard point of knives, in Figure 9-10 A, is designed for cutting depth and design, for example, a 5 / 16-inch box cutter blade of the maximum depth of cut 5 / 16 inches, and an 8 mm square block will be cutting
7、 knives Corner to 8 mm deep, this tool will be very fast Corner block removal of surplus metal. Slice merits of the deal with that, in a small blade was close thinning. This tool is also a very good finishing tool. But please do not confuse the thin band Tool and Tool-off crumbs. A chip-off is actua
8、lly counter-productive tool to cut off the chip flakes. And the standard tool of the Corner, compared with chip breaking tool for the Corner is in its on and get grooving, Figure 9-10 B. This tool generally used to block the Corner of rough finishing. While this tool Corner blocks have sufficient st
9、rength to carry out deep cut, but the longer the chip will cut off the plane around after shedding a lot of accumulation. Chip is so because the tangles and sharp, and the operator is a dangerous, so this is a chip from the need to address the problem. Double, or triple the speed of the feed will he
10、lp to resolve, but this will require greater horsepower and still easily chip very long. Because of the slow processing, however, this action will be a good tool but also because of the small root radius of the processing will be a smooth surface. Especially when processing grey cast iron especially
11、. Cutting Tools appearance Appearance, sometimes called the contour of the floor plan is where you see the vision or the top down or look at the surface. Figure 9-11 illustrate some of the most common form, those who could be on the cutting tools and grinding out successfully be used. National Stand
12、ards in its thread-cutting tool on a tiny plane can be as GB thread, the Anglo-American unity and international standards screw threads. A special tool to outline the thread of the plane is to be ground into the correct size. Tools Corner fixed Corner to a number of knives around the 15 degree angle
13、 while the other knives and cutting of the straight. When the mill in Figure 9-12 A and 9-12 B, for example by the space and the inclination, these must factor into consideration in the review. Figure 9-12 B Tool Corner block the angle is zero, compared with 9-12 A map is a heavier cutting tools, an
14、d the 9-12 A map will take more heat. The same amount of space in front of the two cases are the same. Tool Corner block component and the angle Figure 9-13 Tool Corner block an integral part of the name, and plans 9-14 point of the name, is the machinery industry standards. Grinding Wheel Tool Corn
15、er Block When the cutter is fixed in the middle of Dao, Tool Corner block can not be the grinding. Can not do so for the reasons: because of the large number of Dao and extra weight, making Corner together with the grinding is a clumsy and inefficient way. Too much pressure could be added to round o
16、n the sand. This can cause the wheel Benglie wheel or because of overheating and the rift on the Corner Tool damage. There are grinding to the possibility of Dao. Grinding A craftsman in his toolbox, should always be a small pocket lining grinding tool. Alumina lining a grinding tool as carbon tool
17、steel and high speed steel tool tool. The silicon carbide lining grinding tool grinding carbide cutting tools. Cutting Tools should always maintain smooth and sharp edge, so that the life expectancy of long knives and processing the surface smooth. Cutting tool materials Carbon tool steel cutter Cor
18、ner block usually contains 1.3 percent to 0.9 percent of carbon. These make use of the cutting tool in their tempering temperature higher than about 400 degrees Fahrenheit (205 degrees Celsius) to 500 degrees Fahrenheit (260 degrees Celsius) remained hardness, depending on the content of carbon. The
19、se temperature higher than that of carbon tool steel cutter will be changed soft, and it will be the cutting edge. Damaged. Grinding blades or cutting speed faster when using carbon tool steel cutter will be made of the blue, this will be in the imagination. Tool will be re-hardening and tempering a
20、gain. So in a modern processing almost no carbon as a tool steel blade. Low-alloy steel cutting tool in the carbon steel tools added tungsten, cobalt, vanadium alloying elements such as the consequences. These elements and the hardness of high-carbon carbide. Increased tool wear resistance. Alloy to
21、ol steel that is to say there will be no hard and fast with hot red when the knifes edge can still continue to use it. Low-alloy steel cutting tool is relatively small for a modern processing. High-speed steel with tungsten of 14 percent to 22 percent, or Containing 1.5% to 6% of the W-Mo (molybdenu
22、m which accounted for 6 percent to 91 percent). From high-speed steel tool made of a rigid heat, some high-speed steel also contains cobalt, which is formed of rigid factor. Cobalt containing high-speed steel tool can maintain hardness, more than 1,000 degrees Fahrenheit (or 540 degrees Celsius) bla
23、de will become soft and easily damaged. After cooling, the tool will harden. When grinding, you must be careful because of overheating and cold at first, so that profile Benglie Zhucheng a variety of metal alloy materials have a special name called Carbide, such as containing tungsten carbide cobalt
24、 chrome. In little or iron carbide. However, its high-speed steel cutting speed than the maximum cutting speed is higher 25 percent to 80 percent. Carbide Tool General for cutting force and the intermittent cutting processing, such as processing Chilled Iron. The past, Carbide Tool is mainly used fo
