Method for the production of a hardened guide shaft for a linear guide

摘要

A method for the production of a hardened guide shaft for linear guide is disclosed, in which teeth are formed in a shaft, which is then passed through a circular inductor without rotation. The magnetic flux of the circular inductor is controlled to reduce the flux in the area of the teeth, thereby hardening the teeth without overheating them. The remainder of the shaft is hardened through a magnetic flux greater than that supplied to the teeth area.
