Wheel honing process parameters for honing tubes: influence and optimization
In industrial manufacturing, honed tubes are widely used in hydraulic, pneumatic and lubrication systems and other fields, requiring high precision and good surface quality. The wheel honing process is a common method in the manufacture of honed tubes, and the selection of its process parameters directly affects it.
Process parameters and their effects
1. Allowance distribution (2ap): The allowance is the processing allowance of the honing front hole, usually expressed as 2ap. Appropriate allowance distribution is the key to ensuring honing effect and accuracy. If it is too small, it will lead to insufficient processing, and if it is too large, it may lead to over-honing.
2. Workpiece (or honing head) speed (Vc): The workpiece speed determines the cutting speed during the honing process and has a direct impact on the roughness and removal rate of the machined surface. Increasing Vc is beneficial to increasing the removal rate, but too high Vc may lead to a decrease in the surface quality of the workpiece.
3. Feed (f): The feed determines the depth of each cutting and directly affects the processing accuracy and surface quality. Choosing the appropriate f value is the key to ensuring processing stability and accuracy.
4. Contact pressure (P): Contact pressure affects cutting force and surface quality. Excessive pressure may cause surface damage to the workpiece, while insufficient pressure may affect the cutting effect.
