673FA/LA can
produce finishes as
fine as sub 1 µin Ra.
Use of 673FA/LA abrasives
in Step 2 may reduce final
polishing time up to 50%.
Final polish is typically
performed using slurry on a
felt pad.

Smooth
Trizact abrasives deliver a consistently flat, fine finish
3M Trizact Diamond Abrasives consist of precisely-shaped three-dimensional structures
distributed uniformly over the substrate. As these structures wear, fresh, sharp diamond abrasive
is continually exposed to the workpiece – resulting in faster, more consistent cutting throughout
the life of the material.

Why are the I.D. numbers printed on the disc face?
The imprint on the face of the Trizact 673FA/LA disc serves three purposes:
1. It identifies the product and grade
Trizact 673 FA/LA abrasives provide
outstanding flat grinding & finishing
performance on a wide range of
technical ceramics, metals and optical
substrates including:
• Spinel
• Sapphire
• Alumina
• Zirconia
• Ferrites
• Tungsten
carbide
• Ferroelectric
ceramics
• Silicon nitride
• Silicon
carbide
2. It is used as a quick visual indicator for proper pad break-in/dressing
3. It indicates when disc life is over
Trizact 673FA/LA discs must be properly broken-in before use. As shown in the
photos below, when the printing on the surface of the disc is completely gone
from the tops of the hexagon structures, the disc is sufficiently broken in and
ready to use.
For a more complete discussion of recommended pad mounting and
conditioning procedures, see Technical Bulletin 61-5002-8259-7.

Ask
the
Expert
Expert tips, tricks & techniques for getting the
most out of your Trizact 673FA/LA discs
What type of lubricant should I use?
3M recommends a 90/10 mixture of water with any water-based (aqueous) coolant, such as
Sabrelube 9016 – although any glycol-containing solution or plain water is satisfactory.
™
What lubricant flow rate should I use?
Use this equation: Lubricant flow rate = .393 x (pad OD - ID ), with flow rate expressed in ml/min
and pad OD/ID in inches.

Note: Increases or decreases in coolant flow rate can significantly impact pad wear and cut rate stability
How can I optimize my stock removal rates?
3M Trizact Diamond Abrasives 673FA/LA
are available in a wide range of grades for
grinding and finishing solutions:
™
™
• Coarse grind, to achieve part dimension
and planarity
• Intermediate grind and pre-polish, to help
reduce total cycle time

Stock removal rate is a function of several machine and process variables. If you experience
unstable removal rates, consider the following:
• Modify pad dressing/conditioning process
• Improper lubricant type or flow rate
• Too fine or too coarse a grade for the application
How should I store machine-mounted Trizact 673FA/LA pads between shifts?
Discs should be kept wet on the lapping machine when not in use. If the pads are allowed to dry, a
short dressing cycle should be utilized to re-condition the pads.
How should discs be prepared for extended storage?
Clean and allow to dry. Remember to re-dress before use.
How do I remove Trizact 673FA/LA from machine plates?
A10, A6, A3
All grades/constructions are available
with PSA attachment. Discs available
in 5"–110" diameter, other shapes
on request.
Pads are easy to remove. Begin by pulling the pad away from the plate on an outside
edge. If adhesive residue remains on the plate, use a solvent such as 3M General
Purpose Adhesive Cleaner to dissolve the residue.
