• How to choose better milling cutter body

  2021 / 02 / 23

  Milling cutter is a kind of rotary cutter with one or more cutter teeth for milling. When working, the cutter teeth cut off the allowance of the workpiece intermittently in turn. Milling cutter is mainly used for machining plane, step, groove, forming surface and cutting workpiece on milling machine. In my opinion, we should pay attention to the body and carriage of milling cutter when we choose milling cutter: is milling cutter used on NC machining center or ordinary milling machine. And the material and hardness of milling cutter. Milling cutter specifications, such as: edge length, full length, edge diameter, shank diameter, etc. If it is used on CNC machining center, it should choose the whole cemented carbide. Ordinary milling machine can use white steel. The hardness of white steel milling cutter is softer than that of cemented carbide milling cutter. High speed steel cutter is cheap and has good toughness, but its strength is not high. It is easy to make the cutter, and its wear resistance and thermal hardness are relatively poor. The thermal hardness of high speed steel milling cutter is about 600 degrees, and its hardness is about 65hrc. Obviously, when milling hard materials with white steel, if the coolant is not in place, it is easy to burn the cutter. This is one of the reasons why the thermal hardness is not high. Cemented carbide milling cutter has good thermal hardness and wear resistance, but its impact resistance is poor. It will be broken if the blade is dropped casually. Cemented carbide is made of powder metallurgy, with hardness of about 90hra and thermal property of about 900-1000 degrees. Therefore, white steel is suitable for ordinary milling machine, alloy milling cutter for CNC machinin

  When it comes to toolholders, in fact, we are not unfamiliar with them. The commonly used toolholders in NC machining are mainly divided into: drilling toolholders, boring toolholders, milling toolholders, threaded toolholders and straight toolholders. Shandong shenganbei has been doing CNC tool holder, to see the tool holder mechanism selection and use of maintenance knowledge! As there are many kinds of toolholders, how to choose the toolholder depends on the classification and positioning of the enterprise's products. What kind of processing depends on what kind of machine tool you choose. The tool handle follows the interface between the machine tool and the spindle. If the machine tool and spindle are selected, the general type of toolholder will be determined. For rough machining and conventional machining, the general BT type interface is usually selected; for finishing machining, the ISO series small toolholder may be selected, which is light in weight and can operate at high speed, as well as HSK series, which is suitable for more comprehensive toolholders. The structure of tool holder of CNC machine tool is divided into integral type and modular type. The working part of the clamping tool of the integral tool handle is integrated with the handle used for fixing and positioning on the machine tool. This kind of toolholder has poor adaptability to the transformation of machine tools and parts. In order to adapt to the transformation of parts and machine tools, users reserve various specifications of toolholder, so the utilization rate of toolholder is low. Modular tool system is an advanced tool system. Each tool holder can be assembled by a series of modules. According to different machining parts and machine tools, different assembly schemes can be adopted to obtain a var

• What material is good for the toolholder?

  Aluminum alloy when it comes to the handle material, it must be aluminum alloy. For beginners, this material is anodized to any color you want. In addition, it is a very durable handle material. Its characteristics, take up will not be so heavy, now commonly used aluminum alloy is t6-6061 alloy. Its surface texture design can ensure that the handle of aluminum alloy is firmly grasped, which is comfortable and smooth to use. But the advantages must have disadvantages, such as the anti-collision force is not strong, will lead to scratches or dents; cold weather holding, holding is not very comfortable. Compared with aluminum alloy, stainless steel is not light in weight; however, stainless steel has excellent durability, anti rust and corrosion resistance, although it is not completely impermeable; but as far as metal handle material is concerned, stainless steel is undoubtedly the best metal, and the stainless steel used is 410 / 416 / 420, etc. In addition, the stainless steel handle is smooth, so the manufacturer will add some etching or ripple on it to increase the friction. Many times, you will see that stainless steel is combined with plastic and rubber to make it easy to grasp. However, stainless steel handle is generally not used in daily carrying or heavy cutting tools because of its heavy weight. 6Al / 4V: 6% aluminum, 4% vanadium and 90% pure titanium are widely used in titanium alloys. It is light in weight and has better corrosion resistance than any metal material. It is also a common metal material. The handle is mild, and can be treated with positive surface or pearlescent treatment. In addition to the handle, titanium is also used as a wire lock material due to its good elasticity.
