Extended vibration sweep capabilities simplify grinding machine diagnostics

Keywords: Vibration measurement

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 4 The 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.
