The effect of ball mill on the morphological and structural features of cellulose has been described by Okajima and coworkers. 20 They treated microcrystalline cellulose derived from cotton linters in a planetary ball mill at 200 rpm for 48 hours in dry and wet conditions with three solvents (water, toluene, 1butanol). They observed that ...

The surfaces of all connecting joints or fits, such as shell and head flanges, trunnion flanges, trunnion liner and feeder connecting joints, should be coated with a NONSETTING elastic compound, such as Quigley "OSeal", or "Permatex" to insure against leakage and to assist in drawing them up tight. DO NOT USE WHITE LEAD OR GREASE.

Two fluted end mills can be used to plunge into a workpiece like a drill. 2 and 3 flutes are generally for aluminum, 4 flutes is better for stainless steel. More flutes are better cutting, but come at a higher price. End mills with more than two flutes should not be plunged into the work. Fillets can be produced with ball end mills.

Remember the old adage, "Measure twice. Cut once.". Checking alignment of a gantry system is important enough to do the right way the first time. Laser alignment systems reduce gantry wear and tear, prolong the life of a gantry system and reduce the downtime and scrap material by keeping the system properly aligned.
