P7 is a multifunction device that in a single structure of modular sizes can manage the main control functions necessary to drive the grinding process: Measurement in process and post process, balancing of the grinding wheel, Noise Analysis caused by the impact wheel / piece, wheel / diamond or by accidental impacts, control of the operating environment …

the grinding and regulating wheel can be reduced to a minimum through the optional use of acoustic gap control for dressing detection. Depending on the grinding task, stationary dressing tools such as diamond blades and single-point diamonds or rotating dressing tools such as dia-mond dressing discs or diamond profile rolls are available.

Grinding machines are powerful and designed to operate at high speeds. If a grinding wheel shatters while in use, the fragments can travel at more than 300 miles per hour. In addition, the wheels found on these machines (abrasive, polishing, wire, etc.) often rotate at several thousand revolutions per minute. The potential for

(Schmitt Industries Inc.: Portland, OR) -- Schmitt Industries Inc., a global provider of precise test and measurement systems, has added an advanced grinding-machine balancer control platform, the SB-5500, and an acoustic emission (AE) monitoring system, the AE-1000, to its line of products for the grinding industry.

The acoustic emission sensors allow the machine tool to automatically respond to those events to facilitate gap control, diamond dresser control, and crash detection. "We are pleased to feature both the SB-5500 and the AE-1000 at the IMTS 2010," says David Case, Schmitt vice president of operations.
