What is Thread Milling? Thread milling is a metalworking process to cut threads at different sizes through the circular ramping movement of a rotating tool, the thread pitch is created by the lateral movement in one revolution. Different from tapping, thread milling is primarily applied to large workpieces.

THREAD MILLING REFERENCE GUIDE | 7 Benefits of Thread Mills Left and right handed threads Thread mills are not left hand or right hand specific. While the thread mill is interpolating, the thread mill must move up or down 1 pitch in the Z axis to create the thread's helix. If the Z axis is not moving, the thread mill will

Thread Milling Advantages There are a variety of reasons thread milling is used instead of other threadmaking operations, specifically tapping. As previously stated, a thread mill can address a range of hole diameters. The diameter of a tap is fixed. For large diameters, thread mills can be more economical. Large taps can be expensive.

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 good finish.

Threadmills are cutters used in CNC millling machines to cut internal and external threads using a process called "thread milling." The other threading process for CNC Mills is Tapping . On lathes, single point threading (turned threads) and taps are used.

There's little chance of successfully thread milling metals much above 45 HRC. And if you're going to try to tap them, be prepared to duck the flying shrapnel when the tap explodes! Internal thread grinding and, on rare occasion, orbiting sinker EDMing are about the only ways to produce good threads in materials harder than 45 HRC.

As a rule, thread mills are limited to threads no smaller than 1⁄8" (3.175mm), and because of the high cutting forces and resulting tool deflection, are generally limited to threading holes about 3 diameters deep. On the other hand, taps for #000-120 watch threads are readily available, and an extension tap can reach roughly 20 diameters deep.
