Onboard measurement Many gear grinding machines are more accurate due to the onboard measurement system. Because the machine is used for measurement, thin abrasive cutting disc for metal is not necessary to remove the gear from the workbench and send it to other places for inspection, which avoids the secondary installation error during rework. During processing, the gear is first analyzed by the on-board measurement system, and the measured parameters are compared with the theoretical design parameters to determine the required correction amount. After the control system collects these correction data, the grinding gear processing state is automatically adjusted, and then the grinding is performed. And measurement. Repeat the cycle until the required accuracy is reached. The integrated on-board measurement and on-board correction system make modern gear grinding machines more efficient.
