There are all sorts of jobs that require the right metal used when making a specific part. Weight and durability have to be taken into the equation. That is why when needing custom work, such as aluminum machining, the quality has to be considered. The business that does this work has to understand all the needs before even starting to work with the metal. That takes experience and care from the start that comes from a culture of customer relations above all else.
Most companies claim that they do what the customer requires, but usually there are a lot of negotiations. Making parts to fit the customer needs is more about listening than anything else. Aluminum machining requires that the company knows what their client requires without wasting time on anything else. Measurements and knowing where the part goes does much more to keep people coming back. The wrong part can cause unbalanced machines or excessive wear in the wrong places. That never needs to happen as long as the aluminum is shaped with a team approach.
Another way that a machine shop shows their experience is by knowing how to get the right quality metal before the machining even begins. The most experienced company knows the right quality of metal required for aluminum machining. This will determine the quality of the work that comes out of their machine shop.
