cBN grinding wheels show outstanding advantages for grinding parts made of carbon steel after heat treatment. This type of cutting tool material is commonly used in the manufacturing of machine parts with high requirements on tolerance and surface finish. This research focuses on studying the influence of parameters such as depth of cut (t) and feed rate (F) on the grinding coefficient and surface roughness in the hole grinding process of heat-treated C45 carbon steel with Monolayer Metal Bonded cBN Grinding Wheel by Electroplating Method (MMB grinding wheel). The experimental method is applied grinding holes with a diameter of Φ18mm using a cBN grinding wheel of size Φ10mm. The C45 steel workpiece is heat-treated to reach a hardness from 45 ÷ 48 HRC. By changing the values ​​of t and F, the experimental results showed a significant influence on the grinding productivity and tool wear, grinding coefficient, and surface roughness.

摘要

cBN grinding wheels show outstanding advantages for grinding parts made of carbon steel after heat treatment. This type of cutting tool material is commonly used in the manufacturing of machine parts with high requirements on tolerance and surface finish. This research focuses on studying the influence of parameters such as depth of cut (t) and feed rate (F) on the grinding coefficient and surface roughness in the hole grinding process of heat-treated C45 carbon steel with Monolayer Metal Bonded cBN Grinding Wheel by Electroplating Method (MMB grinding wheel). The experimental method is applied grinding holes with a diameter of Φ18mm using a cBN grinding wheel of size Φ10mm. The C45 steel workpiece is heat-treated to reach a hardness from 45 ÷ 48 HRC. By changing the values ​​of t and F, the experimental results showed a significant influence on the grinding productivity and tool wear, grinding coefficient, and surface roughness.
