Fasteners Suppliers need specially customized tools to solve three problems, special shape, special strength and hardness, and special chip removal and chip removal requirements.

1. The workpiece to be processed has special shape requirements.

 For example, the tool required for processing is lengthened, the end tooth is inverted R, or there are special cone angle requirements, shank structure requirements, blade length size control, etc. If the shape of this type of tool is not very complicated, it is actually easy to solve. The only thing to note is that the processing of non-standard tools is relatively difficult. Therefore, the user should not overdo it if it can meet the processing requirements. Pursuit of high precision. Because high precision itself means high cost and high risk, it will cause unnecessary waste to the production capacity of the producer and its own cost.

2. The processed workpiece has special strength and hardness.

If the workpiece has been heat-treated, the strength and hardness are high, the general tool material cannot be cut, or the knife is very strong. This requires special requirements for the tool material. The general solution is to choose high-end tool materials, such as cobalt-containing high-speed rigid tools with high hardness to cut and temper the workpiece materials, high-quality cemented carbide tools can process high-hard materials, or even Milling instead of grinding. Of course, there are some special cases. For example, when processing aluminum parts, there is a kind of super-hard tool on the market that is not necessarily suitable. Although aluminum parts are generally soft, it can be said that it is a product that is easy to process, but super The material used for hard tools is actually an aluminum high-speed steel. This material is indeed harder than ordinary high-speed steel, but when processing aluminum parts, it will cause the affinity between the aluminum elements, which will increase the wear of the tool. At this time, if you want to get high efficiency, you can use cobalt high-speed steel instead.

3. The workpiece to be processed has special chip-retaining and chip-removing requirements.

At this time, you should choose a smaller number of teeth and a deeper chip flute, but this design can only be used for materials that are easier to process, such as aluminum alloys.

Stud Manufacturer's non-standard tool processing design and processing process, there are many problems need to pay attention to: the geometry of the tool is relatively complex, during heat treatment, the tool is prone to bending, deformation, or local stress concentration, which should be at the time of design Attention should be paid to avoiding parts where stress concentration is likely to occur. For parts with large diameter changes, bevel transitions or step designs are added. If it is a slender piece with a relatively long diameter, it needs to be inspected and straightened every time it is quenched and tempered during the heat treatment to control its deformation and runout. The material of the tool is relatively brittle, especially the material of cemented carbide, which will cause the tool to break once the vibration or the processing torque is large during processing. This is the case when using conventional tools. It is not likely to cause much damage, because the broken tool can be replaced, but in the processing of non-standard tools, because the possibility of replacement is not great, so once the tool breaks, it will cause a series of problems, such as delivery Extension, etc., will cause great losses to the user
