JML DOC #: 2278V608, 2278V609, 2278V610

A. PNSY shall provide thirty-six (36) base piece “T60” laps. Laps are manufactured from 303 stainless steel. No fabrication heat treatment/hardening is performed following manufacture.

a. 1/2 IN Blank: T60, sheet LS-2 per DWG 820-5295154

i. 180, 300, 600 B. No testing required per sections 5 & 7 of ASTM-B-733.

C. (2278V608) Apply 180 grit [170-200 mesh, 88-74 micron] diamond abrasive on both end surfaces of twelve (12) base laps described in paragraph A, above (provided by NETR 2022-49) as shown on sheet LS-2 of DWG. 820-5295154. Diamond plating shall follow industry practice for nickel plated diamond tools where the diamond grit is embedded on the base lap by electrodeposition of nickel. Particle size shall be as described above. Plating shall extend over the lap end to the edge inner tangent minimum, but not to the inside diameter or slot beyond the plane of the lap end. Loose or flaking plating is not acceptable. Vendor will apply grit size/part number and angle required by sheet LS-2 of DWG. 820-5295154 following plating by the vendor.

D. (2278V609) Apply 300 grit [270-320 mesh, 53-44 micron] diamond abrasive on both end surfaces of twelve (12) base laps described in paragraph A, above (provided by NETR 2022-49) as shown on sheet LS-2 of DWG. 820-5295154. Diamond plating shall follow industry practice for nickel plated diamond tools where the diamond grit is embedded on the base lap by electrodeposition of nickel. Particle size shall be as described above. Plating shall extend over the lap end to the edge inner tangent minimum, but not to the inside diameter or slot beyond the plane of the lap end. Loose or flaking plating is not acceptable. Vendor will apply grit size/part number and angle required by sheet LS-2 of DWG. 820-5295154 following plating by the vendor.

E. (2278V610) Apply 600 grit [470-1000 mesh, 36-22 micron] diamond abrasive on both end surfaces of twelve (12) base laps described in paragraph A, above (provided by NETR 2022-49) as shown on sheet LS-2 of DWG. 820-5295154. Diamond plating shall follow industry practice for nickel plated diamond tools where the diamond grit is embedded on the base lap by electrodeposition of nickel. Particle size shall be as described above. Plating shall extend over the lap end to the edge inner tangent minimum, but not to the inside diameter or slot beyond the plane of the lap end. Loose or flaking plating is not acceptable. Vendor will apply grit size/part number and angle required by sheet LS-2 of DWG. 820-5295154 following plating by the vendor.

F. Plating process of diamond abrasive described above shall be per ASTM-B-733, Type I, SC1, Class 2, .0002” thick.
