Control Gauges For Internal Measurement

Qmarz Mechatronic & Metrology offers electronic size Control Gauges for internal measurement. The average diameter of the workpiece during the grinding cycle is measured with a Qmarz ID in-process gage head. The gage head traces the bore of the workpiece with two fingers. The fingers are inserted into the part from the opposite side as the grinding wheel. The fingers touch the part at the 12 `O’ clock and 6 `O’ clock position to avoid interferences with the grinding wheel. The diameter information of the gage head is used to indicate the end of the finishing cycle when the target diameter is reached. Bed mounted (internal): two point gauging electro magnetically operated lifting-off the gauging arm with fine adjustment range up to 10 mm.
