Grinders Have a Tough Job—These Wheels Make it Easier
3M Abrasive Systems, St. Paul, MN, introduces Cubitron II bonded abrasive grinding and cutoff wheels that boast pre- cision-shaped grain technology, enabling faster cutting. Grains stay sharper longer, say company officials, and the wheels require less pressure (as much as three times less) than conventional grinding and cutoff wheels, helping to reduce opera- tor fatigue and increase productivity.
While conventional ceramic abrasive grains are irregular in shape and work by plowing through metal, causing significant heat buildup, grains of Cubitron II grind- ing wheels continuously fracture to form sharp points and edges. This helps the abrasives slice cleaner and faster, stay cooler and last longer. Use the wheels in place of traditional grinding wheels com- prising aluminum-oxide, alumina-zirco- nia or ceramic grain.

Lubricant Mixers Designed to Support Plant-Wide Distribution
Industrial Innovations, Wyoming, MI, introduces a line of Pro-Mix lubricating sys- tems designed to mix the desired content of lubricant concentrate and water for dis- tribution through an in-plant piping net- work. Each machine connected to the net- work automatically receives a continuous supply of pressurized lubricant mixture. Additionally, the systems can be manu- factured to supply as many as three dif- ferent lubricant mixtures to each press, optimizing pressroom flexibility.
Pro-Mix systems feature stainless- steel reservoirs for stabilizing liquids prior to mixing. A patented Pro-Drive assem- bly ensures thorough mixing, control and pressurizing of the mixture, if nec- essary. Additionally, fluid-level status
indicators continuously monitor the level of the two fluids and either refill on demand or discontinue service if levels reach a low level during operation.
Unique characteristics include a mix- ture-testing function, which mechani- cally tests the mixture being produced and varies the amount of water applied to the mixture, optimizing mixture stability
and process control.
The systems come in three models.
Pro-Mix III and V are large units that use pump/valve assemblies to refill the reservoirs, while the Pro-Mix I relies upon gravity for reservoir refill using mechanical ball-float switches. Industrial Innovations: 616/249-1525; www.industrialinnovations.com
