I'm reaching out to inquire about the circular machines I need for our upcoming project. Specifically, I'm interested in different sizes that would fit our specifications. Can you provide details on the pricing for the various models you have available, particularly those that can accommodate different diameter ranges? It would be great if you could also include information on any additional features or variations available for these machines, as well as the lead times for delivery.
