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. 3M Trizact Film 568XA has ™ The Scienceof ™ shown outstanding results on glass substrates. 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. Diamond-containing structured abrasive Cloth or film backing Pressure-sensitive adhesives Polycarbonate support backing 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.

Use this equation: Lubricant flow rate = .393 x (pad OD - ID ), with flow rate expressed in ml/min and pad OD/ID in inches. 2 2 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 Prod ID Backing Available Grades (micron) 673FA Y-wt cloth laminated to polycarbonate backing A300, A160, A80, A45, A30, A20 673LA 5-mil film laminated to polycarbonate backing 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. ™ Product Use: All statements, technical information and recommendations contained in this document are based on tests or experience that 3M believes are reliable.
