New Standard Holder for 3ΧD Line

Transcription

1 Standard Holder for 3ΧD Line With remarkable market feedback for the multi-functional tool, is expanding the range to accommodate a holder diameter up to 3ΧD as a standard item. While the conventional products had machining depth limits of 2.25ΧD, the new range allows stable operation up to 3ΧD. has also introduced a heavy alloy shank to the vibration free and accurate machining.. This guarantees The new 3ΧD line is available with various types with a diameter range from 8mm to 32mm where the existing standard inserts can be used. NPA Product Announcement No. 125 /5

5 Technical Information Insert positioning Cutting edge for drilling should be positioned in the center of tool body. Cutting edge for drilling Correct Correct Wrong Coolant pressure Pressure must be above 2bar in 3.0xD drills, regardless of drilling diameter. (Optimal pressure is above 5 bar) Optimization of chip shape Material with low carbon content (Low Carbon Steel/Low Carbon Alloy Steel) High speed machining is recommended to make the chips thinner as many problems are caused by thick chips. Material with medium to high carbon content (Carbon Steel/Alloy Steel) If too tight? Increase speed if the speed is slow or reduce feed. If too loose? Reduce speed if the speed is high or increase feed. Set-Up Core Ø Ø/2 Please check formation of core and its size after drilling 3mm to 6mm depth and diameter. Core should be within mm. Please adjust Y-axis of tool body by using clamping unit if it is available or reverse the tool body 180 and fix it into a turret to check the core again if clamping unit is not available. If a core does not appear, It can cause breakage of insert and vibration when drilling or turning. If the size of core is over the recommended limit. It will cause overload and vibration.
