How long will a mixing tube last?
A "worn" mixing tube is like a worn tool bit: It is difficult to say when a mixing tube is fully worn, but as it wears, it becomes a less effective cutting tool. (although once it starts to go bad, the wear rate accelerates). For precision work, a new mixing tube performs better than a used one. How long a mixing tube will last depends on a number of factors, including the sales person that you talk to. Numbers from 20 to 80 hours are fairly typical, although it is possible that they may wear faster, or last longer, depending on circumstances.
So what's the real cost?
When looking at costs such as mixing tubes and jewels that are expensive wear parts, consider the "total cost of operation", and compare it with the productivity of the machine. When you make such a comparison you will quickly see that an abrasivejet will probably be the most profitable machine tool in your shop - by far. Consider that your operating cost of the machine will vary between $20 and $35 per hour, but for "typical" jobs you will earn between $60 and $150 per hour, with $120/hour being quite typical.
Price varies considerably depending on regional factors such as competitors and local markets. Reasearch this carefully when looking to purchase a machine.
When pricing the work, it is often more sensible to price based on a "per part" price, instead of "per hour". Often profits can be maximized this way, and it is possible to then realize the benifits of faster cutting machines, and/or machines with multiple nozzles.
