Processed sample of nozzle holes \u2013 No.1<\/h4>\n

The photos below show the cross-cut samples of the nozzles having the function for merging six flow channels into a PCD of 2.5 mm. By suppressing drill runout, these fine holes are penetrated on the open hole surface without burrs. <\/p>\n

– Material: SUS316\u3000 \/ – Product thickness: 15 mm
\n– Diameter of six nozzles: 0.2 mm \u3000\/ – Nozzle inclination angle: 35\u00b0<\/p>\n

\"\"\"\"<\/p>\n

\"\"\nPCD stands for Pitch Circle Diameter, so the left figure shows the six holes evenly arranged on the circle with the pitch circle diameter of 2.5 mm.\n<\/p>\n<\/div>\n\n\n
