Embodiment Construction

[0019] The new process of turning thread processing is to use the following steps to complete the thread processing on the workpiece:

[0020] Use a rough turning tool to remove a large amount of cutting through rough machining to form a workpiece with a thread prototype;

[0021] Replace rough turning tools with fine turning tools;

[0022] Finish machining with a fine turning tool to process the workpiece to the required accuracy by correcting the thread profile and the cumulative error of the thread pitch.

[0023] The precision turning tool cycle used for finishing is used as a rough turning tool in the next step of workpiece thread roughing. This can greatly save tools. For some difficult-to-machine workpieces, continuous use of multiple rough turning tools for rough machining and continuous use of multiple fine turning tools for finishing. After the tool change, use eye observation, color inspection or endoscopic observation to solve the positioning deviation after the tool ...

Abstract

The thread turning process includes the following steps: 1. rough machining of workpiece with rough turning tool; and 2. correcting thread form and eliminating the accumulated error of thread to obtain the required machining precision with finishing tool. The present invention has reduced wear of the finishing tool and raised thread machining precision.

Description

Technical field [0001] The invention belongs to the field of general mechanical engineering technology, especially thread processing technology. Background technique [0002] A large number of threads commonly used in mechanical engineering need to be turned. The thread is divided into internal thread and external thread. For the processing of two kinds of threads, it is mainly made by turning at one time. [0003] The traditional method of turning the thread is to directly turn the thread into several times with a knife. This traditional processing method has the following disadvantages: [0004] Firstly, the cutting frequency of different parts of the tool is different due to the fractional cutting of the tool, and the correct tooth profile of the tool cannot be guaranteed. [0005] Second, due to the increase in the frequency of tool use, the speed at which the tool wears and becomes dull increases, resulting in an increase in the cumulative error of thread accuracy, especiall...
