  • Thread Rolling: What Is It? How Does It Work? Process, Types

    2021-11-8 · Thread milling can generate both internal and external threads. Grinding: Instead of cutting the stock, this process uses abrasive tools to remove metal. This is usually done in conjunction with other threading processes. Thread grinding is done to produce precision threads and threads with a Thread milling, simplified Cutting Tool Engineering,2012-9-1 · A thread mill imparts a finer surface finish than a tap. Thread mills produce a thread in one or more passes. “With thread milling, you can probably do it in one pass if it is a softer material, like aluminum,” Harvey Tool’s Davis said. “But in a hard material, you could take more passes without breaking the tool.
