DESCRIPTION
The P7SE system is designed to check and process the acoustic signals with acoustic sensors, which can be managed contemporaneously and four logic channels. P7SE is ideal for machining operations with grinding wheels in CBN, which require a specific acoustic noise analyser to optimise the grinding wheel dressing operation.
P7SE acquires the acoustic signal automatically, analyses it and compares it with programmed noise thresholds in order to improve the production process. By defining a noise threshold the operator can perform the collision check and the air gap check:
Collision Check (Crash): a correctly defined noise threshold allows for the detection of accidental collisions of the grinding wheel with the part and therefore protect the machine parts.
Air gap Check (Gap): by defining a noise threshold the contact between the grinding wheel and the part can be detected and define precisely the moment that the approach speed passes to the feed speed. This check optimises the cycle time.
The P7SE system consists of a Master card that coordinates and manages the acoustic function card and coordinates the communication mode between the machine logic and the operator interface (MHIS).
The P7SE features fieldbus (Profibus and Interbus S) and serial connections for a complete integration with the machine control.
BENEFITS
Possibility of an automatic control which is therefore independent of the operator's capability
Increased production quality
Air gap check
Reduction of the dressing cycle time
Greater protection against collision for the grinder and the machine
Increased life of the individual machine components
TECH SPECS
Power supply: 24V DC
I/O static interface
Remote panel or PC connection: Ethernet or RS232
Profibus interface
