Frequently Asked Questions About Thread Milling

Q. DO I NEED SPECIAL SOFTWARE TO PROGRAM MY THREADMILL?

Q. WHICH WAY DO I MILL WITH A THREAD MILL?

A. MOST COMMON WAY TO THREAD MILL IS UP. ALTHOUGH IT IS POSSIBLE TO MILL UP
OR DOWN WITH A THREAD MILL,USING A G03 OR G02 CIRCULAR INTERPOLATION TO
CLIMB OR CONVENTIONAL MILL WHICHEVER IS DESIRED.



Q. WHERE IS A THREAD MILL AN ADVANTAGE OVER TAPPING?

A. DIFFICULT TO MACHINE MATERIALS. CLOSE TOLERANCE THREADS WHERE PITCH
DIAMETER HAS TO BE CONTROLLED. BETTER SURFACE FINISHES WHEN THREAD MILLING
POSED TO TAPPING.



Q. DO I HAVE TO TAPER REAM A HOLE WHEN USING A NPT OR NPTF THREAD MILL?

A. NO THE THREAD MILL WILL GENERATE THE TAPER DURING THE MACHINING PROCESS.
THE TAPER IS ONE OF THE CHARACTERISTICS OF THE TOOL.



Q. CAN I USE A SMALLER THREAD MILL TO GENERATE A LARGER DIAMETER THREAD WITH
THE SAME PITCH (T.P.I.)?

A. YES THE IMPORTANT PART OF A THREAD MILL IS THE PITCH (T.P.I.) AS LONG AS
THE LENGTH OF CUT IS THERE THAT IS NEEDED.

Q. CAN I CUT A RIGHT OR LEFT HAND THREAD WITH MOST THREAD MILLS?

Q. IS THREAD MILLING HARD TO PROGRAM?

A. NO MOST MACHINE MANUFACTURES HAVE SOFTWARE THAT CAN GENERATE A "G" CODE
PROGRAM JUST BY FILLING IN SOME SIMPLE PARAMETERS. IF YOU DO NOT HAVE SUCH
SOFTWARE ON YOUR MACHINE YOU CAN GENERATE YOUR OWN PROGRAM USING THE "G02"
& "G03" CODES AND A "R" VALUE OR WITH "I" & "J". THE PROGRAM WILL NEED TO
USE A "X","Y" AND "Z" MOVE TO GENERATE THE THREAD.
