AI Technical Summary
Existing technologies for machining the internal threads of reverse-type nuts suffer from problems such as large grinding volume, long grinding time, high grinding wheel wear, high cost, and poor machining accuracy, especially in machining deep-hole parts with large length-to-diameter ratios.
A combined turning and grinding machining equipment for internal threads was designed. It combines a deep hole turning tool and an internal thread grinding wheel spindle, and adopts a process of turning first and then grinding. Through the tilting angle device of the internal thread grinding wheel spindle and the turning tool device, multiple processes can be completed in one clamping, reducing the number of clamping times and improving accuracy and efficiency.
It effectively controls processing costs, improves processing accuracy, reduces grinding time and grinding wheel wear, thereby lowering processing costs and increasing processing efficiency.
