Rettificatrice cilindrica universale DMTG 1450B usata in vendita

A Universal Cylindrical Grinding Machine is a versatile and precision-oriented machine tool used for the grinding of cylindrical and non-cylindrical surfaces. It employs an abrasive wheel as its cutting tool to remove material from a workpiece, resulting in fine finishes, tight tolerances, and accurate dimensions. Here’s an overview of its features and functions:

1. Cylindrical Grinding: The primary function of a Universal Cylindrical Grinding Machine is to grind cylindrical surfaces on workpieces. These can include external and internal diameters, tapers, and shoulders.
2. Versatilità: “Universal” in its name signifies its ability to accommodate a wide range of workpiece shapes and sizes. The machine can be set up to grind both external and internal surfaces, making it suitable for various applications.
3. CNC or Manual Operation: Universal Cylindrical Grinding Machines can come in both CNC-controlled and manual versions. CNC machines offer automation and precision, while manual machines provide greater operator control for specialized tasks.
4. Workpiece Holding: These machines use various methods to secure the workpiece, such as centers, chucks, collets, or special fixtures. The choice of workholding method depends on the specific workpiece geometry and requirements.
5. Mola abrasiva: The abrasive wheel used for grinding is a critical component. Different types of grinding wheels, such as straight, tapered, or contoured, can be used based on the workpiece shape and material.
6. Wheelhead Movements: The wheelhead, which holds the grinding wheel, can move along the X and Z axes. This movement allows for precision positioning of the wheel relative to the workpiece.
7. Swiveling Wheelhead: Many universal cylindrical grinders feature a swiveling wheelhead that can be adjusted to grind tapers or other non-cylindrical shapes.
8. In-Process Gauging: Some advanced machines are equipped with in-process gauging systems that measure the workpiece dimensions during grinding. This helps maintain tight tolerances and ensures consistent quality.
9. Sistema di raffreddamento: Grinding generates heat, so a coolant system is typically used to control temperature and wash away chips and debris, thereby improving surface finish and tool life.
10. Meccanismo di medicazione: Grinding wheels wear over time and need periodic dressing to maintain their cutting efficiency. Some machines have automated dressing systems for convenience.
11. Accuracy and Tolerance Control: Universal Cylindrical Grinding Machines are known for their ability to achieve high levels of accuracy and tight tolerances, making them crucial in industries such as aerospace, automotive, tool and die, and precision engineering.
12. Surface Finish: These machines can produce excellent surface finishes, reducing the need for additional finishing operations.
