   Received the Danish customers proofing needs, request the production of a trapezoidal locking thread, automatic lathe processing, and bottom is relatively small, it is not possible to use thread milling cutter, only the use of acme thread tap.
Technical difficulty: normal thread angle is straight, and this thread is the inner thread with concave arc, the outer thread with convex arc, concave and convex match, play the role of anti loose. The design is very good, but the problem of production, the negative arc angle grinding wheel how to interfere?
Rothschild engineers and production units, as well as the end of the terminal customers to explore, I am the Secretary of the optical curve grinding and five axis tool grinding change, after trial production in one fell swoop to solve technical problems.
