Schmitt Industries, Inc. engages in the design, manufacture, and sale of high precision test and measurement products. Segments The company operates in two segments, Balancer and Measurement. Balancer segment The company’s principal product line for this segment is the Schmitt Dynamic Balance System (SBS), which consists of a vibration sensor, a computer control unit, and a balance head that is placed either externally on the grinding wheel spindle with the use of a spindle mounted adaptor or internally inside the spindle bore. The SB-5500 control panel contains up to four slots for additional circuit boards designed for specific functions, such as manual balancing, balancing using hydro chambers and process monitoring, which involves the detection and analysis of high frequency noise, known as acoustic emission (AE), generated by the grinding process. Customers can also detect and analyze the AE signal generated during grinding or wheel dressing to help monitor and improve the grinding process. Customers include both end user operators, as well as manufacturers of grinding machines worldwide for various industries that utilize the grinding process, including the automotive, industrial, aerospace, and medical industries where specifications and operating tolerances on machined parts are increasingly precise. The SB-5500 is fully automated, eliminating the need to pre-balance parts, such as grinding wheels. The SB-5500 also includes an optional Acoustic Emission Monitoring System (AEMS) control card, which uses proprietary acoustic sensor technology to monitor the AE signal generated on the grinding machine during key events in the grinding process. The AEMS card allows rapid, automatic grinding wheel in-feed, right up to the point of initial contact of the grinding wheel with a new part loaded in the machine. The system can automatically detect the initial contact and very quickly report this event to the machine control, stopping the wheel in-feed without operator intervention. The AEMS card allows the grinding machine’s operating system (known as a computer numeric control or CNC system) on the machine to monitor the acoustic levels and detect any unexpected contact when it happens. The system then reports that abnormal contact and instructs the CNC program to stop the grinding process, usually within one millisecond. The SB-5500 also offers two process control cards that fit inside the control panel to provide enhanced control of the grinding process: the ExactControl card and the ExactDress card. The ExactControl process control card offers multi-functional grinding process control capability by detecting and analyzing either the AE signal pattern or the machine power fluctuations and then using one of seven process control strategies to adjust and optimize the grinding process based on that signal data, resulting in improved part quality and reduced operating costs. The ExactDress control strategy is also available in a separate process control card as part of the AEMS system to automatically monitor and control the grinding wheel dressing process. Additional SBS products include the SB-2000 and the AE-1000. The SB-2000 is an easy-to-use, compact manual balancing system offering both one and two plane manual balancing capabilities. The system comes in a dedicated machine installation version (SB-2000) and a portable version (SB-2000-P). Each version of the system displays up to four digits of resolution for vibration and six digits for RPM readings and supports a spindle speed range of 30 to 100,000 RPM. The portable SB-2000-P version attaches magnetically to any location on the machine for easy setup and use. The AE-1000 is a dedicated AE control platform that reduces air machine grinding time and alerts the operator to potential grinding wheel crash conditions by using proprietary AE detection technology to monitor the high frequency signals generated by the grinding process. Notable features of the SBS system include its ability to fit almost all grinding machines, ease of installation, compact and modular construction, ability to balance a wheel while on a machine, virtual eliminatio
