FLUID POUR & SET
Mattison Surface Grinder
This picture shows the typical adhesion pattern used in new machine applications. This same rough milled surface is found on the flat of the table.
In this picture, take notice to the alignment blocks on the external surfaces. This means of alignment simplifies the straightness alignment. The use of an adjustment screw on blocks located down both sides of the table between the table and bed way clearance surfaces not only eliminates the need for gluing on shims but makes it possible to make a final precision alignment after setting the table in the Moglice.
In this photo you can clearly see the proper masking of a vee way. The oil return in the bottom of the vee way as well as the .250" gap on both sides are filled with foam stripping and then covered with masking tape. It is important to understand why this is done. The vertical surfaces in these locations should not be duplicated line to line. This would make separating the table from the bed almost impossible without fracturing the bearing surface.
A common practice of combining 3 - 5 kits of fluid Moglice in a large container is shown here. The technician first combines the resin in one container, keeping in mind not to combine too many at a time. The container should never be more than _ full as mass quantities will cause an accelerated cure or shorten the pot life. The resin can be pre-mixed at this time to insure sedimentation has not occurred.
In this picture the technician is adding the hardener liquid to the resin, which starts the reaction of polymers. The pot life for the fluid Moglice is 45 - 60 minutes and this is adequate time for application and assembly.
In this photo a portable mixer is being used. Care must be taken not to exceed 100 rpm as higher rpm's during the mixing process will generate heat and shorten the pot life.
After pouring fluid Moglice in the bed it is spread out evenly on the flat. This reduces mass and helps to extend pot life. The flat way is poured first for this reason, and then the vee way.
A pre-determined amount of fluid Moglice is being poured into the dammed molding site. A thin stream is poured because it breaks any possible air inclusions which occasionally can be introduced during mechanical mixing.
Just prior to setting the table into the fluid Moglice, a putty knife should be run up and down the Moglice on the flat way, slightly crowning it to the center of the way as shown.
After the table is set, alignments are re-checked and adjustments made if needed.
The table and bed are left undisturbed for 24 hours to cure.
The table is first jacked free of the bed using a hydraulic or screw-type jack between the table and the bed. Once released it is raised straight up and clear of the bed. The rolling of the table is shown. Mattison became very proficient with the pour and set method of molding.
