The price of a single head pipe polishing machine can vary depending on several factors such as the brand, model, features, and quality.
 

In general, a basic single head pipe polishing machine can cost around $1,000 to $2,000, while a more advanced and high-quality machine can range from $3,000 to $8,000 or more.
 

Some factors that can affect the price include the size of the machine, the type of polishing method it uses, the motor power and speed, the material of construction, and additional features such as automatic feeding, dust collection systems, and variable speed control.
 

It's important to note that while price is an important consideration when purchasing a pipe polishing machine, it's also important to consider the quality and durability of the machine, as well as the level of customer support and after-sales service offered by the manufacturer.
 

Before making a purchase, it's recommended to research various brands and models, read customer reviews, and compare prices and features to ensure you get the best value for your money.
