Internal thread milling program

Each selection has a video, showing you the tool in operation, and a listing of all pertinent tool data on the screen. Define your milling strategy: climb or conventional, number of passes, and language; then select from one of our pre-loaded post processors Sinumerik, Heidenhain, Fanuc, Philips, Mazatrol or Hurco.

The software will create your thread milling program, which you can email, print or transfer as needed. Need Help? Click here to contact Tech Support with your question.

Remember that this is half the pivot point value. The ramp-in move is a helical interpolation move with the X and Y axis moving incrementally 0.

Look at line N70 and note that the ending Z absolute position is 0. During this helical move the absolute Z value reduces by 0. We hope this methods is easy follow and helpful in further understanding thread milling. Programming Thread Milling Milling is a great way to create a thread. Feed to depth N60 G1 X 0. There are single row and multi row thread mills. A single row has one row of teeth.

A multi-row has multiple teeth. The can thread faster because they cut multiple grooves in one pass. However, they only cut a single pitch thread size as the distance between thread grooves is fixed.

The teeth of a threadmill are larger and stronger than taps because of the reduced need for chip clearance. This makes them less likely to break. Thread Milling is better for harder materials because you can cut the material in smaller steps, and speeds and feeds can span a wider range than a tap, which is limited by the pitch of the thread being tapped.

Thread Milling requires less horsepower than tapping, which may be an advantage for lighter-weight CNC machines. The lower cutting forces of thread milling can be advantageous in long reach and thin wall applications where tool deflection and chatter are problems.

A single threadmill of the right type can be used to cut many thread sizes. A separate tap will be needed for each thread size. On parts with multiple threads, there can be considerable toolchange savings with thread milling. There is also savings in reducing the amount of tooling inventory that must be kept on hand for standard thread sizes. You can thread mill odd-sized threads for proprietary applications.

A thread mill can be used to back chamfer the hole. Thread mills have no need for special tension compression holders or tapping heads. This is an advantage on CNC Machines that lack rigid tapping capability. Taps get increasingly expensive as size increases.

At some point, threadmill cutters are cheaper than very large taps. While coolant can be used, most manufacturers suggest dry machining is the first choice when thread milling.

Exceptions would be stainless steel reduces work hardening , aluminum reduces chip welding , and cast iron to keep the dust down. Otherwise, a good compressed air blast will be fine. Thread Mill Cutters For starters, most threadmill cutters are made of carbide. Image courtesy of Lakeshore Carbide. Integrated Countersink Many threadmill manufacturers offer versions with integrated countersinks at the top of the threadmill to eliminate the need for a tool change where countersinking or chamfering is desired almost always!

Solid Carbide vs Indexable Thread Mills As with most any other tool type, Threadmills are available as indexable tooling with replaceable inserts. Single Profile or Spiral Flute? Through Coolant? Through Coolant is most important for evacuating chips in blind holes. Toolholders for Thread Milling Most but not all! I picked an uncoated threadmill and the specs say 0.

Reverse Rotation vs Synchronous Milling Assume clockwise spindle rotation.
