There are several items to keep in mind when looking at the cost per hour to run a waterjet. These costs should be relatively universal regardless of the manufacturer of your waterjet. When we provide costs to our customers we always give a conservative target, which we believe can actually be achieved. We don’t have any commissioned salespeople; therefore no one here is going to give you an overly optimistic best-case scenario with regards to the cost to run your machine. Our goal is to see you succeed with your machine, not just to sell one to you. We are focused on what is best for you, not what is best for RICHEL. Talk with us and test us out.
Keep in mind that a waterjet manufacturer whose survival is dependent upon commissioned salespeople convincing you to purchase their product, tend to be swayed in their presentation of waterjets. They may describe it as the only ideal, perfect, lowest cost, sole solution to both your engineering as well as your life’s problems. We all know at the end of the day the waterjet is just a tool to help you succeed in your business goals.
The facts are the same regardless of manufacturer:
- Fact: Abrasive is not supplied by the waterjet company and is the largest consumable cost.
- Fact: The abrasive flow rate is determined by the size of your pump, not the manufacturer.
- Fact: You should plan on your ruby orifice lasting 40 hrs - salespeople may say 80 hrs.
- Fact: You should plan on a diamond orifice lasting 500 hrs - salespeople may say 1,000 hrs.
- Fact: If the numbers are that close that using a conservative number of an additional $10/hr or more is a problem – you shouldn’t buy a waterjet.
