![]() Sometimes, it's from our team here at Next Generation Tooling & at other times it's by one of the innovative manufacturer's we represent in California and Nevada. sounds right to me.i had to knock out the lefties and put in new standard right hand threaded studs to change wheels. Our technical section is written by several different people. The entire process can be achieved by interpolating in a downward direction and reversing the orbit direction. ![]() A left-hand thread is produced by orbiting in a clockwise direction while bringing the 'Z' axis up one pitch per 360 degrees.A right-hand thread is produced by orbiting in a counterclockwise direction while bringing the 'Z'-axis up one pitch per 360 degrees.For example, if the "arc-in" is over 90 degrees, the 'Z'-axis departure must be 1/4 of the thread pitch. It is always best to "arc-in" and "arc-out" when thread milling.Īny "arc-in" and "arc-out" movements must have a corresponding 'Z'-axis motion during the 'X-Y' circular moves. With small sizes and with difficult to cut material, it may be necessary to remove the material in several passes. Next, mill either the 'X' or 'Y' axis to the required thread pitch diameter. In other words, the secret is to tighten the same amount after hand-tightening. ![]() If one side took more turns to get it to hand-tighten, then add (or subtract) that number before starting and turn that amount into the side that took more turns. Then take apart and do the same on the other side. Then, position the thread mill to the required depth. Count the number of turns to get it to hand-tight. To produce internal threads, drill the minor thread diameter to its appropriate size. ![]()
