The detailed heat treatment process of boring bar made of 38CrMoAl steel boring machine
Quality (the workpiece to obtain a comprehensive mechanical properties, quenching and tempering generally take 28-30HRC) - fine car to wear the amount of (each side of the single-sided are retained 0.2-0.25mm) - pliers milling milling line - milling tail and related holes
(To reduce the internal stress of the workpiece) - rough car (each side of the single side of the amount of 1-1.5mm.) - tune (to reduce the material of the segregation)
To the requirements - pre-drilling line cut hole - line cut square hole to the requirements - high frequency quenching - grinding the ministry to the requirements.
