Pat Mooney Inc., Addison, Ill., introduced PMI upcut saws that cut aluminum extrusions and provide a burr-free finish, according to a company release. The saw, housed under the worktable, travels up through the work piece. The saws have 5- horsepower to 7.5-horsepower motors, and include pneumatically controlled saw blade feed and pneumatic clamping systems with adjustable clamping pressure to prevent distortion of thin wall profiles. PMI saw worktables are coated with chromate to prevent marring on the exterior of the work piece. Safety features include a safety machine enclosure that protects the worktable, two-hand cycle start activation and a safety limit switch.Pat Mooney Inc.
