The choice of tool system is one of the important contents in the configuration of CNC machine tools, because the tool system not only affects the production efficiency of CNC machine tools, but also directly affects the processing quality of parts. According to the performance of the CNC machine tool (or machining center) and the characteristics of the CNC machining process, the tool and the tool holder system can be optimized to achieve twice the result with half the effort. A commonly used...
With the development of high-speed and high-precision machine tools, the spindle speed has been greatly improved. However, in order to take advantage of the cutting precision and dynamic balance of high-speed machine tools, in addition to the good design of the machine itself, the selection of 9009 with the appropriate tool holder and The cutting tool is also an important factor to effectively protect the life of the high-speed spindle and ensure the normal operation of the machine tool. It is...
The collet chuck is a more commonly used clamping tool in machining. It is usually used to loosen and lock the thread at the end of the collet to clamp and loosen the workpiece. This is a cumbersome part of the large-volume, simple-cutting parts, such as the end-faced drilling parts of Figure 1 and the end-faced and drilled parts shown in Figure 2. The labor intensity of the workers is large and the benefits are not high.
Due to the different tool holding methods, a large number of factors such as dimensional accuracy, surface quality, changing time and tool wear are affected. Therefore, the holder has a direct influence on the quality of the workpiece and the processing cost. In the cutting process, the tool holder is the key interface between the tool and the machine tool. In all machining occasions, whether or not the correct shank is selected will affect many factors such as: dimensional accuracy, surface...
Spring collet chuck processing art: when using, first put the chuck into the pressure cap, gently operate the clip spring, waiting for the eccentric equipment of the pressure cap to be concave into the clip spring groove, and place the force along the arrow mark to develop the clip spring, that is, the cone can be broken. The spring collet chuck needs to turn to the sliding sleeve, which can make the drilling and Tapping Sleeves communicate rapidly. When drilling, the Morse sleeve locks itself;...
As an important "bridge" connecting machine tools and cutting tools, tool holder is related to machining accuracy, tool life and processing efficiency, and ultimately affects the processing quality and cost. Therefore, it is very important to choose a proper tool handle. Because the requirements of various processing are different, corresponding to them should be different clamping methods of tool holders. Here, the general characteristics of various tool holders are briefly introduced. I....
The collet chuck is a kind of centering clamping mechanism with high centering accuracy. It is mostly used for semi-finishing or roughing of smaller diameter (d≤30mm) bar parts. Figure 1 is a schematic view of the shape of the collet in a natural state (regardless of the expansion). In use, the collet is moved axially within the spindle taper hole, and the chafer of the collet is contracted in the A direction under the action of the taper surface, thereby achieving centering clamping of the...
Here are some basic knowledge about the tool holder: 1. The function of the tool holder Machining center spindle + tool handle + tool, the function of tool handle: when connecting with the spindle of machining center, the connection accuracy and rigidity should be ensured; when connecting with the tool, the clamping force and accuracy should be ensured; and the tool handle itself should ensure rigidity, balance and accuracy. The taper fit is usually used between the spindle and the tool holder...
HSK tool holder is the Bing of high speed cutting tool. At present, hollow short taper shank (HSK) has become more and more popular in the field of cutting, because it has obvious advantages over 7:24 large taper shank in precision, rigidity, high applicable speed and convenient tool change. The publication of HSK's formal international standards will make it more widely recognized by all countries. However, in the application of this new type of tool holder, due to its structural...
Tool holder material Antlers (STAG): Originally from the wild stag, it has a slightly roasted color after being fired. It is a very elegant portable pocket knife material. BONE: Originally derived from natural animal bones, it is usually textured and has a variety of bright colors such as green, blue and black. It is one of the most versatile portable folding knife handle materials. G-10: Laminated plastic sheet originally from glass fiber. She is a glass fiber that is immersed in a resin and...
In the actual field processing, the use of powerful milling tool holder is very common, which is used by many users as the basic tool holder. Here are some key points that some samples will not mention. (1) On the Clamping Force Powerful Milling Tool Holder It is difficult to quantitatively answer the question of "how many kg m is the minimum required gripping force (to keep the knife from dropping)". Taking Dazhaohe powerful milling tool holder with holding force of 300 kg m as an example, the...
