A thread mill is simply an end mill with the thread form and a specific pitch. The machine can be programmed to helically interpolate to the desired diameter. A 1/4-20 thread mill can produce a 1/2-20 or even a 7/8-20 thread making it an excellent choice for uncommon thread sizes or large diameter threads. Left.
Thread Mills from SmiCut (ThreadBurr) will give you a nice entry and a burr free thread. The cutting length is laser marked on the tool and you can find it as well in the catalogue.

The diagram below shows the working area for a CNMG 120408 insert, based on acceptable chip breaking in relation to feed and depth of cut. • First choice is -PM geometry • Use -PR geometry for high f n/a p or interrupted cuts • Use -PF geometry for low f n/a p. The chip illustration is an example from the diagram and cutting data ...
Basics in threads What is a thread? Threads are classifi ed according to the main functions they perform in a component. Primary functions of a thread: • To form a mechanical coupling • To transmit motion by converting a rotational movement into a linear movement, and vice versa.
Thread Milling is a method for producing a thread by a milling operation. The most common way to produce a thread is still by tapping and turning but today we see more and more milling and this is because CNC milling machines with three
Programming examples. The following programming examples are based on the thread milling tool centre path, which requires no tool radius compensation other than an offset for tool wear. These examples are purely for guidance only and may need to be altered to suit the CNC control you are using.
