The trimming edge is a critical part of forming components in stamping dies. To ensure smooth material discharge, precise dimensional requirements are typically imposed on the edge height. Traditionally, the common approach involves flipping and inverting the die for machining from the reverse side. However, this operation proves extremely difficult for large dies, demanding significant manpower, resources, and time for clamping, calibration, and other tasks. This method fails to meet the demands for high efficiency, high productivity, and unattended machining.
The most effective solution is back milling for cavity pocketing. Our newly developed [Back Milling (Cavity Pocketing) Cutter for Trimming Edge Relief, MSU/MUC Type] achieves highly efficient and precise unattended CNC machining of edge relief via back milling. The tool design comprehensively addresses factors such as cutting edge strength, tool head interference avoidance, and corner deceleration.
