Precautions for purchasing high-frequency quenching machine tools

Покупката на високочестотни закалени машини is mainly analyzed from several aspects:

1. First of all, we must understand the size of the quenched workpiece and choose the appropriate equipment model. It is not recommended to use a machine with a low power for quenching, which will affect the overall quenching effect.

Second, the depth and area of ​​high-frequency quenching that need to be heated; heating depth, heating length or heating area, whether to be heated as a whole, the hardness layer requires a deep choice of low oscillation frequency, and the shallow hardness layer should choose the one with high oscillation frequency.

Third, the heating speed required for high-frequency quenching; the heating speed required is fast, and the power should be relatively large, and the quenching speed will be better for the quenching effect.

4. Continuous working time of high-frequency quenching equipment; continuous working time is long, relatively select induction heating equipment with slightly larger power.

5. The connection distance of high-frequency induction equipment; the connection is long and even needs to be connected with water-cooled cables, and relatively high-power induction heating equipment should be used.

6. High-frequency production process; Generally speaking, for processes such as quenching and welding, you can choose a lower power and a higher frequency; for annealing and tempering processes, choose a higher relative power and a lower frequency; red punching, Hot calcination, smelting, etc., require a process with a good diathermy effect, so the power should be selected larger and the frequency should be lower.

7. Material for quenching machine tool workpieces; among the metal materials, those with high melting point are relatively high-power, and those with low melting-point are relatively low-power; those with low resistivity are relatively high, and those with high resistivity are relatively low.

High-frequency hardening machine tools are mainly a combination of high-frequency hardening equipment and hardening machine tools, which are mostly used for shaft gear quenching. When selecting equipment models, please provide all parameters to the manufacturer to help you choose and recommend suitable equipment models.
