[0002] A thread grinder is a thread processing machine tool that uses a formed grinding wheel as a grinding tool to process precision threads. Thread grinders are mainly used in production workshops and tool workshops in the machinery manufacturing industry, and are most commonly used in workshops in tool factories and measuring tool factories that produce thread processing tools and thread measuring tools.

[0003] In the related technology, a solution of an internal thread grinder (Announcement No.: CN217253425U) was found after searching. When in use, the processing distance is adjusted by setting the front and rear moving device and the horizontal moving device, which effectively improves the processing accuracy and meets the production needs. The product is processed by coordinating the grinding wheel spindle box and the sanding spindle box to ensure the product processing accuracy and effectively improve the work efficiency. It has a compact structure and is simple and convenient to operate.

[0004] While the aforementioned machine can process the workpiece using forward and backward motion and lateral motion, it lacks all-around grinding, so some parts of the workpiece may not be fully machined and require secondary processing. This secondary processing can lead to a decrease in overall machining accuracy, which can affect the accuracy of the workpiece, resulting in reduced practicality and inconvenience. In view of this, we have introduced the five-axis vertical internal thread grinder. Utility Model Content
