Coventry-based (UK) grinding wheel and component balancing specialist,Schmitt Europe Ltd has extended the vibration monitoring capabilities of its proven SB-4500 electronic control unit.
The equipment's new vibration sweep function provides users with a valuable diagnostic tool, by enabling them to pin-point the amplitude and frequencies of vibrations in grinding machines throughout pre-defined wheel speed ranges (Plate 4).
Plate 4The SB-4500's new vibration sweep function provides a valuable diagnostic tool, by enabling the amplitude and frequencies of vibrations in grinding machines to be determined throughout pre-defined wheel speed ranges
Results can be displayed graphically or reported as a listing of the 20 most severe vibration values with their corresponding frequencies; allowing common faults, such as excessive wear in machine bearings or ancillary pumps and motors, to be isolated rapidly and effectively. In addition, the new capability– which is suitable for grinding machines with operating speeds from 300 to 30,000rev/min – will diagnose further machine-induced vibrations, as well as external environmental problems that may adversely affect the grinding process.
The SB-4500 control unit is a core Schmitt product, offering simple and reliable operation of the company's extensive range of balancing and process control systems. It is ruggedly constructed and provides intuitive, push button controls, with a clear graphical display in a choice of five languages options as standard. Its modular design also allows the addition of plug-in PCB cards for simultaneously controlling up to four balancing, in-process gauging or Acoustic Emission Monitoring Systems (AEMS).
The controller interfaces easily with machine tools via a PLC I/O or RS 232 serial port and can be supplied either as a stand- alone unit, or in panel mounted module form.
