Threading by machining can produce a high-precision screws, however the machining time is longer which resulting in higher production costs.
If the products do not require high-precision thread profiles, it is effective to produce thread by rolling/knurling machines.
In this way, threading process by rolling machines allow for high efficiency machining operation, and it significantly reduces production costs of threading processes.
We, E&H Precision has over 10 rolling / knurling machines from NISSEI Co., Ltd. and PROFIROLL TECHNOLOGIES GMBH.
