basic information
**Reasons for Cost Increase Due to Edge Chipping** Edge chipping often occurs relatively early with a small number of processes. - The threads in the center are usable, but due to edge chipping, they become unusable and require correction. - After correction, the thread width is reduced, the outer diameter is smaller, and there may be waste. - After step processing, setup work, especially for head-mounted workpieces, and rolling work becomes difficult, leading to high costs. - With a small number of processes leading to corrections, the cost of edge correction is added, resulting in a high total cost. Early edge chipping often leads to increased rolling costs. For more details, please contact us or download the catalog.
