Thermal Finishing Methods

1 Annealing
Annealing is a CNC metal finishing process that involves heating a material until it recrystallizes, then putting it in sand to cool gradually or cooled to room temperature in the oven. Although the cooling process is slow, it helps reduce the metal’s hardness, increase its elasticity, and enhance its cold working capacity.

2 Heat Treating
It entails a series of processes used to modify the microstructure of materials to improve their physical and mechanical properties, including ductility, strength, and hardness.

3 Tempering
This heat treatment process involves exposing the metal to high heat below the critical point and held before cooling to achieve a balance of toughness and hardness in metals after hardening.
