ABSTRACT:
Hard thread milling methods and equipment provide more precise alignment for a threadably retained component A fuel injector body with a cavity for a solenoid valve is processed by steps including heat treatment before milling threads and also milling a planar seal face to which the threads are located in precise perpendicularly so a high pressure fuel line can be reliably sealed.
