Waterjet Deburring is performed through high-pressure water. It essentially cleans and deburrs at the same time. The most recent innovation in deburring technology is commonly known as High Pressure Water (HPW) deburring. Currently, it is widely used in the automotive industry. It is said to be more part and environment friendly method in removing burrs, chips and other contaminants.
HPW deburring process is preferable than other deburring methods. Its results are often very clean and free from residues. Unlike hand deburring, waterjet deburring is not labor intensive. It can even reach into difficult and complicated areas. Compared to robotic deburring, it can smooth out small and loose chips. Also, parts need not be cleaned before and after deburring.
Basically, the principle of waterjet deburring depends on the force of the high-velocity waterjet passing from a small-diameter opening to attack debris, burrs and chips on the parts' surface. It doesn't endanger or compromise essential part features. The high-pressure waters take off the materials that are not solidly connected to the surface. However, burrs that cannot be removed with 10,000 psi of water are exceptions.
Waterjet deburring is effective on materials such as cast iron, aluminum and other materials with low tensile strength. Take note that harder materials need higher pressure, while soft material only require a low pressure. Also, there are factors that affect the period of deburring. These include the type of machine, the pump power of the machine, the noozle technology and the number of parts or materials to be deburred. In an average, deburring cycle time is a long process. Remember that higher flow rate for a specific pressure result to greater pump power rating.
Generally, conditioned water is utilized for the process. Also, such deburring must be performed at room temperature, and should not use any corrosive or abrasive chemicals.
