　　In the process of machining, it is often difficult to use standard tools for machining, so the production of non-standard tools for machining is very important. Because the use of non-standard cutting tools in metal cutting is more common in milling, so the production of non-standard cutting tools in milling processing is slightly introduced. Due to the production of standard tools for surface measurement of ordinary metal or non-metal parts cutting, overheating processing when the workpiece and hardness increases, or artifacts such as stainless steel is very easy to stick a knife, there are also some the surface shape of the workpiece is complex, or by processing the situation such as the roughness of the surface have higher requirements, standard tools cannot meet the needs of processing. So in the process of processing, the need for the material of the tool, the geometric shape of the knife edge, geometric Angle, etc., targeted design, can be divided into two categories, do not need special custom and need special custom. Tools that do not require special customization are mainly used to solve two problems, such as size problems and surface roughness problems. If is the size problem, you can choose a size close to the required size of the standard tools, through the change of grinding can be solved, but also need to pay attention to two things: the size is not too big, generally not more than 2 mm, because of the size difference is too big, can cause tool change in the trough, the chip directly affect the space and the geometric Angle. If it is the end milling cutter with edge holes can be changed in the ordinary machine tool, the cost is lower, if it is not with keyway milling cutter with edge holes can not be carried out in the ordinary machine tool, need to be changed in the special five-axis machine tool, the cost will be higher. If it is a surface roughness problem, it can be realized by changing the geometric Angle of the blade, for example, increasing the degree of the front and back angles will significantly improve the surface roughness of the workpiece. However, if the machine is not rigid enough, maybe the blunt edge can improve the surface roughness. This aspect is very complicated, and we need to analyze the processing site before we can draw a conclusion. Custom-made tools are needed to solve the following problems. The processed workpiece has special shape requirements, such as lengthening the cutter needed for processing, adding the end tooth inverted R, or has special cone Angle requirements, handle structure requirements, blade length size control and so on. This type of tool if the shape requirements are not very complex, in fact, or easy to solve, the only need to pay attention to the non-standard tool processing is more difficult, therefore, the user in the case of processing to meet the use, should not be excessively the pursuit of high precision. Because high precision itself means high cost and high risk, which will cause unnecessary waste to the production capacity and cost of the producer. The workpiece has a special strength and hardness, such as the workpiece overheat treatment, strength and hardness is higher, the general tool material can not be cut, or stick the knife is severe, this is, you need to put forward special requirements for the tool material. The general solution is to choose high-grade tool materials, such as cobalt high speed rigid tool has a higher hardness to cut quenched and tempered workpiece materials, with high quality cemented carbide tool can be processed high hard materials, or even milling instead of grinding. Of course, there are some special cases, such as in the aluminum processing, there is a called superhard cutting tools on the market is not necessarily appropriate, although the general soft aluminum, can be said to be a kind of easy processing products, but superhard cutting tool adopted by the material is a kind of aluminium high speed steel, the material is harder than ordinary HSS do some, but can cause in the aluminum machining aluminum, the affinity between the tool it will aggravate the wear, at this time, if you want to get high efficiency, can choose cobalt high speed steel. The workpiece has a special chip and chip removal requirements, then should choose fewer teeth and deeper chip tank, but this design can only be aimed at relatively easy to process materials, such as aluminum alloy. Non-standard cutting tool design and machining process, there are many problems need to pay attention to: the tool geometry is more complicated, at the time of heat treatment, tooling prone to bending and deformation, or the local stress concentration, which should be pay attention to avoid in the design are prone to stress concentration parts, parts of larger diameter change, with bevel or transition steps design etc. If the long and thin parts with large length and diameter are in the process of heat treatment, each quenching and tempering shall be checked and straightened to control the deformation and runout. Cutting tool material is relatively brittle, especially hard alloy, the material that makes or once encountered vibration in machining torque is bigger, the tool will break off, this in the machining process of using conventional cutting tools, tend not to do a lot of damage, because the tool is broken can be replaced, but in the use of non-standard cutting tool processing, due to the possibility of replacement is not big, therefore in the event of tool fracture, will cause a series of questions, such as delivery delay, use will cause great losses. The above is for the tool itself, in fact, non-standard tool manufacturing is not so simple, this is a system of engineering. Producers design department's experience and understanding of using the processing status will affect the design and manufacture of non-standard cutting tools, production processing and testing means producers can affect the precision of non-standard cutting tools and geometric angles, producers of Marketing Department repeatedly visit, collect data and information will affect the improvement of non-standard cutting tools, and these will be used to use is crucial the success of non-standard cutting tools. In a word, non-standard cutting tools are special tools produced according to special requirements. Choosing a manufacturer with rich experience will save a lot of time and energy for users.
