There are basically 2 reasons why the Diamond I.D. Slicing Blade should be dressed:
- Build-up of sludge and epoxy
- Uneven Diamond Wear
In case #1 S.M.I. recommends a periodic dressing be performed to help maintain a free cutting surface due to unwanted build-ups of sludge and epoxies. If this is not executed it may eventually load-up and cover diamond surface not allowing a free slice.
In case #2 S.M.I. recommends a corrective dressing be performed to alter the deflection due to normal diamond wear.
**Note: Both cases mentioned above will show signs of blade deflection, wafer surface damage/variation, and is up to your discretion to determine which is the reason why and correct.
Types of Dressing Stones
- Aluminum oxide (white, type A320 HV)… this dressing stick is a non-aggressive type, and is used for the cleaning of diamond surface, on all Mark III and Mark IV versions of SMI I.D. blades, without removing the diamond structure.
Available sizes: 1” x 1” x 6” = $ 11.75 ea ½ “x ½” x 6” = $ 8.75 ea
- Silicon Carbide (green, type GC320 HV)… this dressing stick is a medium aggressive type for truing Mark III version, of SMI I.D. Blades. It is also used for cleaning the diamond surface of Mark V versions.
Available sizes: 1” x 1” x 6” = $ 12.75 ea ½” x ½” x 6” = $ 9.75 ea
- Silicon carbide (black, type C220 HV)… this dressing stick is an aggressive type and is used only, for “truing” or “removal” of all Mark V versions of SMI I.D. Blades. Available sizes: 1” x 1” x 6” = $ 12.75 ea ½” x ½” x 6” = $ 9.75 ea
