I've used TN'S Machining throughout my engineering career, and as a business owner. They have always provided high quality parts under short lead times, regardless of qty. TN'S continues to advance their capability, and is trusted by many companies to produce high precision components, such as are used in fluid power, suspension, and electromagnetic applications. Almost unbelievably, they have spent a lot of time for researching materials and processes for me in order to produce one-off parts, while yet holding prices that are very palatable.
