How to choose the material of the large spindle shaft？

Recently, many customers have asked how to choose the material suitable for the large spindle shaft, and how to choose the hard spindle material suitable for their products. Today, Hengchang Heavy machinery will introduce to you how to choose the material.

The hardness of the large spindle shaft is a relatively important parameter. Whether the hardness is appropriate is directly related to the quality of the product.

The hardness of the motor spindle will vary depending on the material, and the process selected during processing will also be different. At present, the common process treatments include the hardness of the raw material itself and the heat treatment process to harden. Some products have special structures, such as the need to punch ribs on the surface of the product, so the material of the motor spindle cannot be too hard, and some motor shafts have retaining rings, so the hardness range of the motor spindle is between HV500-600. It is more appropriate. If the material selected for the motor spindle is SUS420 series stainless steel, then the hardness range of HV260-320 is more appropriate. But remember that the hardness of the motor spindle cannot be too high. Sometimes the bearing capacity requirement is not very high, so it is enough to slightly temper the motor shaft. Some parts have special requirements, which can be quenched and chrome-plated.
