More Highlights:
Dry Milling Machine: Suitable for milling soft materials such as zirconia and PMMA. It has a simple structure and low maintenance costs but is not suitable for hard materials.
Wet Milling Machine: Suitable for milling hard materials such as glass ceramics. It offers high precision but requires coolant and more complex maintenance.
Metal Milling Machine: Designed specifically for milling metals. It offers high precision and is suitable for high-demand metal restorations but comes with a higher initial investment and maintenance costs.
The choice of milling machine should be based on the actual needs of the dental laboratory, the types of materials to be processed, and the budget.
