SUMIDIA Binderless NPD10 New - General Features By using nano-polycristalline diamond for the cutting edge, these tools achieve excellent wear resistance and fracture resistance compared to tools made with previous polycristalline diamond. In particular, nano-polycristalline diamond makes it possible to achieve improved machining accuracy and longer tool life for machining brittle materials such as carbide, etc. - Characteristics ● Best suited for high precision machining of carbide Achieves high precision machining of carbide with nano-polycristalline diamond, which has excellent wear resistance. ● Maintain excellent dimensional accuracy over long periods Greatly reduces the number of times that the tool must be replaced compared to previous diamond tools, improving work efficiency and reducing total cost. ● Applicable to machining brittle materials Makes it possible to perform turning on brittle materials (ceramics, etc.) that could previously only be machined through grinding. - Applicable Range (Carbide Machining) Hardness: ˂ 88 HRA Hardness: ≥ 88 HRA 0,20 0,20 Depth of Cut doc (mm) Depth of Cut doc (mm) 0,15 0,15 0,10 0,10 0,05 0,05 0 0,05 0,10 0,15 0,20 0 0,05 0,10 0,15 0,20 Feed Rate f (mm/rev) Feed Rate f (mm/rev) - Recommended Cutting Conditions (Carbide Machining) Work Material Cutting Conditions Class Hardness (HRA) SEI Grades Cutting Speed vc (m/min) Feed Rate f (mm/rev) Depth of Cut doc (mm/rev) 70 VM G7 60 ≥ 83 ~ < 88 5 - 20 - 30 0,03 - 0,10 - 0,20 0,03 - 0,10 - 0,20 VC G6 50 VM G5 40 ≥ 88 5 - 15 - 20 0,03 - 0,05 - 0,07 0,03 - 0,05 - 0,07 VC D2 Lower limit value - recommended value - upper limit value, cutting conditions: dry - Machining Accuracy SUMI DIA External Turning of Carbide VC50 (87HRA) Boring of Carbide VM30 (91HRA) Dimensional Deviation (mm) Dimensional Deviation (mm) 0,025 30mm 0,10 Conventional grade 30mm 0,020 ● 0,08 0,015 0,06 Ø50mm Ø26mm ● Conventional grade 0,010 0,04 ● ● ● 0,005 ● 0,02 ● ● NPD10 ● NPD10 ●● ■ ■■■■ ● ● ■■■■■■■■■■■■■■ ■■ ■ ●● ●■■■■■■■■■■■■■■■■■■■ 0 100 200 300 400 500 NPD10 has no dimension 0 200 400 600 800 1000 1200 NPD10 has no dimension Cutting Distance (m) variation even with cut- Cutting Distance (m) variation even with cut- ting distance of 450m. ting distance of 1.100m.
