Customer demand background and challenges
The main problem currently encountered by customers is that the original Sandvik tool is no longer available for purchase for some reason, so they need to find alternative products. The Sandvik tool originally used by the customer uses dovetail welded column-type CBN. This welding method is not yet popular. Most CBN tools on the market currently use V-shaped welding.
Challenges and suggestions for low-speed processing
According to the processing parameters provided by the customer, the speed of the tool is low. Especially under low-speed conditions, the performance of the CBN blade may not reach the best effect. CBN materials can usually play their advantages at higher speeds, because the cutting performance of CBN may not be fully stimulated during low-speed processing, resulting in unsatisfactory processing results.
For this reason, Moresuperhard's professional engineers suggest that you try to optimize the sharpness of the tool to adapt it to low-speed processing conditions. This improvement helps to improve cutting efficiency and processing quality, especially under the customer's processing requirements, it may achieve better performance.
Impact of workpiece clamping problems on processing parameters
The customer's workpiece is a thin-walled cylindrical structure and may face workpiece clamping problems during processing. This workpiece shape has high requirements for tool stability and processing accuracy, so it may also be one of the reasons for using low speed. Thin-walled workpieces are easily affected by cutting forces, so special attention should be paid to stability and vibration suppression during processing to ensure processing quality.
Conclusion
In response to the current problems faced by customers, Moresuperhard selected a CBN tool suitable for low speed and high sharpness to help customers solve the processing difficulties caused by clamping problems. At the same time, it is recommended that customers consider appropriately adjusting processing parameters and optimizing tool performance to improve cutting efficiency and processing quality. The current cutting tool market still needs more technical research and development to provide more tool solutions that meet different processing needs.
