Advantages of Water Jet Machining

It is very versatile and does not suffer any kind of heating problems in order to cause a change in properties of the material. This suits any cut off of the plastic and rubber and their composites but metallic or the ceramic cut offs are left unaffected. No edge scallops will be encountered in water jet machining. Practically, there won’t be much secondary finishing. This cutting method doesn’t add to any hazardous fumes and wastes.
