1.1 General description
The application of the MARPOSS E9 gauging system on grinders offers a highly
reliable solution to the problem of improving the performance of this type of machine
tool.
This chapter contains a general description of the basic parts that form a gauge for
grinders:
• Measuring head.
During the grinding cycle the contacts of the measuring head touch the workpiece.
The mechanical movements of the workpiece that is being ground, transmitted by the
fingers, are converted into electric signals by the transducers and sent to the
electronic amplifier.
• Electronic amplifier.
The electronic amplifier processes the information it receives from the measuring
head, and displays, on the meter fitted on its front panel, the difference between the
actual measurement value and the final value that must be obtained.
The electronic amplifier can have several configurations, depending on the individual
applications. For instance:
• With controls, for automatic cycles;
• Without controls, for read-only cycles;
• With analog output;
• Etc.
