Machine bed details

Machine bed analysis and annealing types: common annealing processes are: recrystallization annealing, stress relief annealing, spheroidizing annealing, complete annealing, etc. The purpose of annealing: mainly to reduce the hardness of metal materials, improve plasticity, to facilitate cutting or pressure processing, reduce residual stress, improve the homogenization of structure and composition, or prepare for the subsequent heat treatment.

1. Complete annealing and isothermal annealing Complete annealing, also known as recrystallization annealing, is generally referred to as annealing. This annealing is mainly used for casting, forging and hot-rolled profiles of various carbon steels and alloy steels of hypoeutectoid composition, sometimes also For welded structures. It is often used as a final heat treatment for some non-heavy workpieces or as a pre-heat treatment for certain workpieces.

2. Spheroidizing Annealing Spheroidizing annealing is mainly used for hypereutectoid carbon steel and alloy tool steel (such as steel cutting tools, measuring tools, steels used in molds). Its main purpose is to reduce hardness, improve machinability, and prepare for later quenching.

3. Stress-relieving annealing Stress-relieving annealing, also known as low-temperature annealing (or high-temperature tempering), is mainly used to eliminate residual stresses in castings, forgings, welded parts, hot-rolled parts, and cold-drawn parts. If these stresses are not eliminated, it will cause deformation or cracking of the steel after a certain period of time or during subsequent cutting operations.
