Question by john New: What is the distinction between surface grinding and wheel grinding?

Very best answer:

Answer by Zzonyx
Surface grinding makes use of a typically rectangular abrasive surface (generally a pad lined with emery paper) which vibrates. Applying some stress on the tool (orbital grinder) a uniform and extremely gradual grinding impact is obtained. It functions greatest on virtually-flat surfaces.
Wheel grinding utilizes a rapidly-rotating abrasive disk (flat, cup or other shape) usually fitted to the tool (an angle grinder). Based on the contact surface with the workpiece (circumference or flat), diverse effects can be obtained. Harder to control, it removes higher quantity of material and is not suitable for finishing function.
In each circumstances gloves, goggles and non-flammable environment are essential for safety.
