What is front to front grinding?

Front to front grinding is a machining process used to grind two parallel surfaces of a workpiece using two grinding wheels. The process involves mounting two grinding wheels on two separate spindles and positioning them in such a way that they face each other, with the workpiece placed between them. The workpiece is then moved back and forth between the grinding wheels, enabling the wheels to grind the surfaces of the workpiece.

This process is advantageous for producing highly accurate and flat surfaces. The two grinding wheels act as mirrors to each other, making it easier to achieve precise flat surfaces. Additionally, front to front grinding is capable of producing high stock removal rates and can be performed on a variety of materials, including metals, ceramics, and plastics.

However, this process requires more complex machinery because it needs two spindles. Additionally, it can be time-consuming because the workpiece needs to be shifted back and forth many times to ensure an even grind. Despite the drawbacks, front to front grinding is an effective process for producing highly accurate and flat surfaces.
