    Non-standard tools require high design and processing

    TIME:2019-03-01

    The main function of the tool is the tool used for machining in machine building. There are many types of tools, including hole machining tools, cutting tools, general tools, etc. Among them, non-standard tools are a special kind, which can meet the requirements of the surface geometry of the workpiece is very complicated, or the surface is rough. Processing requirements when conditions are required. Therefore, it has important production significance. The design and processing requirements of non-standard tools are high. In order to meet the needs of customers, we have to do the following.

    1. The workpiece to be processed has special strength and hardness. If the workpiece is subjected to heat treatment, the strength and hardness are high. The general tool material cannot be cut, or the sticking knife is powerful. This is to make special special for the material of the tool. Claim. The general solution is to use high-grade tool materials, such as high-speed steel cutters with high hardness to cut the tempered workpiece material.

    2, the geometry of the tool is more

The general solution is to use high-grade tool materials, such as high-speed steel cutters with high hardness to cut the tempered workpiece material.

    2. The geometry of the tool is more complicated. When heat treatment, the tool is prone to bending, deformation, or local stress concentration. Therefore, it should be designed to avoid the parts where stress concentration is likely to occur, and the part with large diameter change. , plus the bevel transition or step design.

    3. The workpiece to be machined has special requirements for chip and chip removal. At this time, fewer teeth and deep chip pockets should be used, but this design can only be used for materials that are easier to process, such as aluminum alloy.

    4. The workpiece to be machined has special shape requirements, such as lengthening the non-standard tool required for machining, adding end tooth R, or having special taper angle requirements, handle structure requirements, blade length size control, etc. High precision means high cost and high risk, which will cause unnecessary waste of the production capacity of the producer and its own cost.

    The materials used for non-standard tools also need to be carefully selected. It is necessary to know that when the hardness of the material is high, the wear resistance is also high. When the bending strength is high, the impact toughness is also high. Hard coatings, as barriers to chemical diffusion and heat transfer, slow down the wear of the tool during cutting, which is our main choice. In order to be complicated, when the heat treatment is performed, the tool is prone to bending, deformation, or local stress concentration. Therefore, it is necessary to pay attention to avoiding parts where stress concentration is likely to occur during design, and to increase the diameter change portion. Or step design.

    5. The workpiece to be machined has special requirements for chip and chip removal. At this time, fewer teeth and deep chip pockets should be used, but this design can only be used for materials that are easier to process, such as aluminum alloy.
