The cost of renting a polishing machine can vary depending on various factors, including the location, type of machine, duration of rental, and any additional services or accessories included. It's important to note that as an AI language model, I don't have real-time pricing information. However, I can provide you with a general idea of the cost range.
 

In general, rental prices for polishing machines can start from around $50 to $100 per day for smaller, handheld models. Larger and more advanced floor polishing machines may have rental rates ranging from $100 to $500 or more per day. Some rental companies may offer discounted rates for longer rental periods, such as weekly or monthly rates.
 

Additionally, you may need to consider other expenses such as a deposit or insurance coverage, which can vary based on the rental company's policies.
 

To get the most accurate and up-to-date information on rental prices in your specific area, I recommend contacting local equipment rental companies or searching online rental marketplaces that cater to your location. They can provide you with detailed pricing information based on your requirements and location.
