The SBS AE -1000 reduces air grinding time and alerts the operator of crash conditions by using proprietary acoustic detection technology to monitor and analyze the high frequency signals generated by the grinding process.
The AE-1000 reports initial contact between the wheel and a new part to the machine control system so it can stop wheel in-feed without operator intervention, which can save up to 20% of the typical cycle time. It can also detect and report abnormal contact from an incorrectly loaded part or fixture within milliseconds, allowing the in-feed to be stopped, avoiding a crash, damage or injury.
Position control, used to zero the machine before beginning a grinding ordressing cycle, is possible by detecting the edge of the wheel touching a reference point known to the machine CNC. The CNC thereby can determine the exact position and diameter of a changing grinding wheel.
Monitoring for normal acoustic levels during wheel dressing permits the operator or CNC control to (1) determine if the wheel is being dressed fully across its width, (2) control the aggressiveness of the process, and (3) maintain the quality of the dressed wheel to conserve wheel material.
The AE-1000 works with a variety of SBS acoustic sensors, all of which are easy to retrofit. They are highly resistant to grinding machine coolants
and grinding paste. Their reaction speeds are significantly faster than traditional methods of spindle load or alternative monitoring devices.
