NEW PROTOMAR 300 IN-PROCESS GAUGE FOR CYLINDRICAL GRINDERS INTRODUCED AT IMTS 2010

Marposs introduced its new Protomar 300 in-process gauge for cylindrical grinders at IMTS 2010.

The new Protomar 300 is an absolute gauge with measuring accuracies equal to that of standard in-process gauges. The Protomar 300 gauge, which has a measuring range of 300 mm, has been designed for measuring diameters having continuous or interrupted surfaces of any shape and number of teeth with +/- 2 microns accuracy. Its wide measuring range allows the Protomar 300 to gauge sequentially any number of different external diameters on large parts such as railway axles, mill rolls, printing rolls, electrical motors and wind power generators. All measurements are referenced to a single calibration cycle, thereby eliminating the need for a dedicated setup master for each part or diameter to be ground.

The Protomar 300 gauge is designed for use with the Marposs P7 multi-function control unit, which eliminates the need for special software in the machine CNC for control and machine/operator interface. The Protomar 300 and P7 system provides real-time grinding cycle control through a variety of interfaces and I/O options. When connected to a P7 unit, the same Protomar 300 in-process gauge can be used for post-process roundness checking at the end of the grinding cycle.

Information regarding the status of the shape compared with two programmable thresholds can be provided by the P7 control unit to the machine’s PLC or a remote system to perform further shape control analysis or statistical control to calculate and monitor process and machine capability.
Use of the Protomar 300 gauge and P7 control unit enables high performance and consistent cycle time while reducing and optimizing the grinding cycle.
