Description

Technical Field

[0001] The utility model belongs to the technical field of lathes, in particular to a tool fine-tuning device for a numerically controlled lathe. Background Art

[0002] A turning tool is a tool with a cutting portion used for turning operations. It is one of the most widely used tools in cutting operations. The working portion of a turning tool is the part that generates and processes chips and includes structural elements such as the cutting edge, a structure that breaks or gathers the chips, space for chip removal or storage, and channels for the cutting fluid.

[0003] The cutting portion of a turning tool consists of a primary cutting edge, secondary cutting edges, a front face, a rear face, and a secondary rear face. The type of the tool's front face is primarily determined by the properties of the workpiece and tool materials. Flat-face tools with negative rake angles are suitable for carbide turning tools used for machining high-strength steel and roughing cast steel parts. Flat-face tools with chamfers have a negative chamfer ground onto the positive rake surface to enhance cutting edge strength. These tools are suitable for carbide turning tools used for machining cast iron and general steel parts. For turning tools requiring chip breaking, tools with a rounded face with negative chamfers can be used, or chip breakers can be ground onto the front face of flat-face tools. In large-scale turning operations, not only does the tool's own performance directly impact machining quality, but the angle and depth of its mounting are also crucial. Therefore, frequent adjustments to the tool's mounting structure are required during the machining process, especially during the commissioning phase. Currently, the typical adjustment method involves adjusting the clamping point. This approach is not only inconvenient, but also suffers from low positioning accuracy and often lacks ideal stability. Summary of the Invention
