What are the characteristics of titanium alloy cutting process

?What are the characteristics of titanium alloy cutting process? When the hardness of titanium alloy is greater than HB350, it is particularly difficult to cut, and when it is less than HB300, it is easy to stick to the knife and it is also difficult to cut. However, the hardness of titanium alloys is only one aspect that is difficult to machine. Titanium alloys have the following cutting characteristics.

      Diamond resin matrix type cutting disc, in which the outer ring belt is a resin bond abrasive working layer, and the central part is made of high-strength and high-rigidity metal material, which is mostly used for grooving and cutting of medium and large cutting depths. In the process of turning cemented carbide parts, the hardness of the tool itself must be higher than the hardness of the workpiece to be machined. Therefore, the current tool materials for turning cemented carbide parts are mainly made of high-hardness, high-heat-resistant non-metallic binders CBN and PCD (diamond). ) as the main. For cemented carbide parts with hardness less than HRA90, choose BNK30 material CBN tool for large allowance turning, and the tool will not chip or burn. Carbide parts with hardness greater than HRA90 are generally ground with CDW025 material PCD tools or resin-bonded diamond grinding wheels.

      Although this method has high productivity, it has to manufacture expensive special broaches, which is only suitable for mass production of internal gears with smaller radial dimensions. The generation method, also known as the Fan Cheng method, is a method of cutting out the tooth shape by using the meshing motion of the gear cutter and the tooth blank. Gears with different numbers of teeth, as long as the module and tooth angle are the same, can be processed with the same tool. The methods of processing tooth shapes using the principle of generating (fan Cheng) include shaving and honing and grinding and hobbing.
