CEM has been machining parts for the aircraft operated at my workplace for three years and we have always been pleased with their work.They are ISO certified and have a very robust quality system and their shop has always been very well managed.The amount of equipment they have is impressive, and I actually look forward to auditing them, because its fun just to look at all the stuff they have going on there. I have also always been pleased with their customer service and the professionalism of their employees.I am happy to recommend Cutting Edge to anyone.
