Industrial tube on Instagram: "Cutting tooth grooves with a lathe is a precise machining process used to manufacture components such as gears, splined shafts, and toothed wheels. Although dedicated gear-cutting machines are often used in high-volume production, a lathe can accurately cut tooth grooves when equipped with the proper tools, attachments, and indexing methods. The process requires careful setup, accurate measurement, and controlled cutting to achieve correct tooth shape and spacing.
