3 Carbide Grades HSN The grade utilizes an ISO carbide base grade but has the added benefit of a PVDTiN (Titanium Nitride) coating. is our standard stocked grade and satisfies the greatest range of material applications. should be the first choice for most applications. grade is a TiAlN (Titanium Aluminum Nitride), PVD coated grade recommended for difficult to machine alloys having workhardening or abrasive wear characteristics. This could improve wear life in materials such as stainless steels, nickel alloys, most cast irons as well as graphite resin composites. Our newest coating is a multi-layer hybrid nano coating. This new coating has very good heat resistance and high hardness. The HSN coating is designed for heat treated materials up to 7 HRc. Tool Selection There are critical steps required for optimizing a thread milling operation for any thread to be produced.. Tool Selection. Speed & Feed Selection.

Size: This is the smallest internal major thread diameter a tool of specific pitch and cutting diameter can produce. Any internal mill can be used to produce larger thread diameters as long as the dimension exceeds the required length of full thread. Good machining practices dictate selecting a tool having sufficient mass to mill the desired pitch, thus reducing deflection and premature tool failure. P a g e

Do not refer to tap drill charts for internal pipe tap applications. The internal minor diameter created using tap drill sizes will truncate the minor diameter crest beyond the maximum allowable limits with the exception of two turns from the end of the pipe. The chart to the left recommends the ideal drill size for preparing the bore of an internal pipe thread milling application prior to taper reaming or before going straight to the thread milling operation without reaming the taper. This will produce full crest and root form threads to the L gage line. CNC Programming Data For NPT & NPTF Threads Thread Size Drill Size & & & To produce accurate tapered threads for any pipe thread application having a : or / per foot taper, the CNC program must incorporate an increase in arc radius as the centerline of the spindle moves around the internal centerline of the thread to be produced. For straight threads, a 0 arc move is made around the center with a Z positive move up one pitch. If this were used for pipe threads, the end result would be an oval thread because the - 7 taper ground on the tool cutting edge will move away from the pitch diameter as the tool moves up. To create a perfect pitch truncated cone pitch diameter for pipe threads, the X & Y arc tool path must also increase to match the taper of - 7 as the tool moves up the bore one pitch. This cannot be performed in one 0 G code line. The use of separate lines using 90 of arc move are required. An ever increasing arc radius is incorporated based on the distance moved up (/ pitch) in Z. The end points of each arc move must also include this additional increase in X or Y. The chart above indicates the exact amount of compensation required for each 90 arc move. Page
