The key technology of hole processing is to solve the rigidity and chip removal problems of the inner hole turning tool. The main measures to increase the stiffness of the inner hole turning tool are to increase the cross-sectional area of the tool bar as much as possible, and to shorten the extension length of the tool bar as much as possible.
Cutting tool is an indispensable and important tool in cutting process. No matter it is ordinary machine tool or advanced numerical control machine tool (NC), machining center (MC) and flexible manufacturing system (FMC), it must rely on tool to complete cutting process. The development of cutting tools has an important impact on improving productivity and processing quality. Tool material, tool structure and geometry are the three elements that determine the cutting performance of the tool, among which the performance of the tool material plays a key role. A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. Generalized cutting tools include both cutting tools and grinding tools. The vast majority of knives are for machine use, but some are also for hand use. Since the knives used in mechanical manufacturing are basically used to cut metal materials, the term "knife" is generally understood as a metal cutting tool.
Improvement and application shortening of inner hole turning tool. Combining the above aspects for discussion and analysis, it is necessary to ensure the rigidity of the tool holder and the processing efficiency. Practice has proved that using the improved inner hole lathe to process various holes not only ensures product quality, but also greatly shortens the operator's sharpening and tool adjustment time, reduces the operator's labor intensity, improves processing efficiency, and reduces Processing costs. If the same improved thinking is used, certain modifications can be made to the thread turning tool, the outer circle turning tool, etc., which can also improve production efficiency and reduce processing costs.
An inner hole turning tool belongs to the technical field of machining tools. It solves the problems of relatively large processing limitation and poor chip removal effect of the existing inner hole turning tool. The inner hole turning tool includes a tool bar and a tool head arranged at the front end of the tool bar. The thickness of the tool head is smaller than the thickness of the tool bar. The upper surface of the tool head has a triangular blade installation groove, and the blade is fixed on the In the installation groove, there is an arc-shaped chip removal surface between the cutter head and the cutter head. The chip removal surface extends along the upper surface of the cutter head to the upper surface of the cutter rod. An extruded part that is extruded inside. The utility model has the advantages of wide application range, good stability and the like.
