Rettificatrice senza centri SKS-300

A SKS-300 Centerless Grinding Machine is a type of grinding machine that does not require the use of a spindle or a fixture to locate and secure the workpiece. Instead, the workpiece is supported between two rotating grinding wheels, and the material is removed from the workpiece by the grinding action. Centerless grinding is commonly used for high-volume production of cylindrical components with tight tolerances and excellent surface finishes. Here’s an overview of centerless grinding machines:

Key Components and Operation:

1. Regulating Wheel: The regulating wheel is a rubber or composite wheel that rotates at a slower speed than the grinding wheel. It controls the rotational speed and feed rate of the workpiece.
2. Mola abrasiva: The grinding wheel is typically made of abrasive materials and rotates at a higher speed. It removes material from the workpiece to achieve the desired shape and finish.
3. Workrest Blade: The workrest blade supports the workpiece and maintains its position between the grinding and regulating wheels.

How Centerless Grinding Works:

1. Configurazione del pezzo: On the basis of SKS-300 Centerless Grinding Machine. The workpiece is placed on the workrest blade, which is positioned between the grinding wheel and the regulating wheel.
2. Rotational Movement: The grinding wheel rotates at a high speed, while the regulating wheel rotates at a slower speed.
3. Grinding Process: On the basis of SKS-300 Centerless Grinding Machine. The grinding wheel removes material from the workpiece by cutting and abrasion. The regulating wheel controls the rotational speed and feed rate of the workpiece, allowing for precise material removal.
4. Thru-feed Grinding: In this method, the workpiece continuously moves forward through the grinding and regulating wheels. The grinding wheel removes material along the entire length of the workpiece.
5. In-feed Grinding: In this method, the workpiece is fed axially into the grinding and regulating wheels to achieve specific diameters or features.
