How to choose and replace the tools of CNC lathe?
2023-10-18
CNC lathe is a kind of advanced machinery and equipment, which is used to process all kinds of metal workpieces. The tool, on the other hand, is a very important part of the CNC lathe, and its selection and replacement directly affects the processing quality, efficiency and tool life. The following will detail the selection and replacement of CNC lathe tooling principles.CNC 4 Axis 5 Axis First, the choice of tools Material selection: CNC lathe tool material selection should be based on the workpiece material to be processed to determine. Common tool materials are carbide, high-speed steel, ceramic, CBN, PCD and so on. Cemented carbide tools are suitable for general machining, surface finish requirements are not high workpiece; high-speed steel tools are suitable for general material processing, such as carbon steel, alloy steel, etc.; ceramic tools are mainly used for the processing of high hardness and brittle materials, such as cast iron, quartz glass, etc.; CBN and PCD tools are suitable for high-hardness materials, such as high-speed steel, cemented carbide and so on.Sheet Metal Tool shape selection: the shape of CNC lathe tools include external cutting tools, internal cutting tools, external boring tools, grooving tools and so on. To choose the appropriate tool shape according to different processing needs. Tool material selection: the material of CNC lathe tools mainly includes solid tools and insert tools. Solid tools include carbide tools and high-speed steel tools, suitable for fine machining and high-speed machining. Inserted piece tools are easy to replace and can improve productivity. Selection should be based on specific processing requirements and economic efficiency for comprehensive consideration. Tool size selection: the selection of tool size should be based on the shape of the workpiece and machining requirements to determine. In general, the tool load should be moderate, neither too large to cause easy damage to the tool, nor too small to affect the processing effect.Line Cutting Second, the replacement of tools Replacement principle: tool replacement is mainly based on the degree of tool wear and machining quality to determine. Generally speaking, when the tool is worn to a certain extent, it needs to be replaced in a timely manner to ensure the quality and efficiency of processing. In addition, tool replacement should pay attention to the selection of appropriate tool materials and tool shape to ensure machining quality and machining efficiency. Replacement steps: the steps of tool replacement are generally as follows: (1) Stop: First, stop the CNC lathe and disconnect the power supply to ensure safe operation. (2) Unclamping: Loosen the screws or clamps holding the tool and remove the original tool. (3) Clean the tool groove: Clean the dust and oil stains in the tool groove to ensure flatness during installation. (4) Install the tool: choose the right tool, insert the tool into the tool slot and fix it with the screw or clamp. (5) Adjust the tool: according to the processing requirements, adjust the position and angle of the tool to ensure the processing quality. (6) Trial cutting adjustment: Switch on the CNC lathe, make trial cutting adjustment, check the machining quality, and make further adjustment if necessary. Summary: CNC lathe tool selection and replacement is very important for processing quality and efficiency. In the selection of tools, according to the workpiece material, shape and machining requirements to determine the tool material, shape and size. When replacing the tool, it is necessary to determine whether to replace the tool according to the degree of tool wear and machining quality, and follow the correct steps for replacement. Only the correct selection and replacement of tools can ensure the normal operation of the CNC lathe and the improvement of machining quality.
