**Industries That Use centerless grinding machines**

centerless grinding is a machining process that removes material from a workpiece without the use of a spindle or fixture to hold the workpiece in place. Instead, the workpiece is supported by a work rest blade and guided between two wheels: a grinding wheel and a regulating wheel. This method is highly efficient and precise, making it suitable for a wide range of industries. Below, we explore the key industries that utilize centerless grinding machines and the specific applications within each sector.
