The price of a deep hole drilling and boring machine varies depending on various factors such as manufacturer, model, configuration, and market supply and demand, so a fixed price cannot be given. However, based on the information I have, the price range for deep hole drilling and boring machines is roughly between several hundred thousand to several million.

　　Here are some specific examples and price ranges (please note that these prices are for reference only, and actual prices may vary depending on specific models, configurations, and market conditions):

　　Low price range: Some small or portable deep hole drilling and boring machines may be more affordable, such as some brands of small boring machines that may be priced between 200000 and 300000 yuan.

　　Mid price range: The price of a medium configuration deep hole drilling and boring machine may range from 300000 yuan to 500000 yuan. These types of machine tools usually have high machining accuracy and stability, and are suitable for various machining needs.

　　High price range: The price of high-end, large or specially customized deep hole drilling and boring machines may reach several million yuan or even higher. These types of machine tools typically have higher machining accuracy, larger machining range, and stronger automation capabilities, making them suitable for high-precision and high-efficiency machining needs.

　　In addition, it should be noted that the price of second-hand deep hole drilling and boring machines is usually much cheaper than new machine tools, but the specific price still needs to be evaluated based on factors such as the condition, performance, and usage of the machine tool.

　　In general, if you have the need to purchase deep hole drilling and boring machines, it is recommended that you first clarify your machining needs and budget range, and then consult and compare with multiple manufacturers in order to choose the most suitable machine tool for yourself. At the same time, it is important to choose reputable manufacturers and brands during the purchasing process to ensure the quality and after-sales service of the machine tool.
