Pinpointing vibrations in grinding machines

Schmitt Europe has extended the vibration monitoring capabilities of its SB-4500 electronic control unit.

Schmitt Europe has extended the vibration monitoring capabilities of its SB-4500 electronic control unit.

The equipment's new vibration sweep function provides users with a diagnostic tool, by enabling them to pinpoint the amplitude and frequencies of vibrations in grinding machines 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 30,000 revolutions per minute - will diagnose further machine-induced vibrations, as well as external environmental problems that may adversely affect the grinding process claimed Schmitt.

The SB-4500 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 said the company.
