Quick-Change Workholding Solutions
January 1, 2021
Emuge Corp. offers the QCS-CM quick-change workholding system. With the QCS-CM quick-change system, the machine spindle is fitted with an Emuge quick-change adapter so that the precision clamping device can be interchangeably mounted with minimal changeover time. "In most cases, after the clamping device has been mounted to the adapter, there is no need to adjust the runout of the clamping device. It is only necessary to check runout with the master to verify proper mounting to the adapter," said a company spokesperson.
The QCS-CM utilizes a bayonet disc to uniformly secure the clamping devices to the adapter. Each clamping device has multiple studs that protrude through the bayonet disc. The bayonet disc is then rotated and locked into position, pre-mounting the clamping device to the adapter. The studs are uniformly tightened with a wrench, firmly mounting the clamping device to the adapter against the tapered connection flange. A draw piece attaches the drawbar of the machine spindle to a segmented collet within the Emuge quick-change adapter. The segmented collet enables the machine spindle drawbar to operate various clamping methods, dependent upon the design of the clamping devices. If air sensing or air pressure is required within the clamping device, a channel can be bored through the quick-change adapter. Air sensing is used to facilitate proper workpiece seating to the location points during loading and prior to centering the workpiece. This helps ensure the clamping device only operates when the workpiece is in the correct position. Air pressure is used for pressurizing the clamping devices to aid in preventing coolant from penetrating the device.
"Advantages of the QCS-CM system include providing an extremely stable mechanical connection with few components, maintaining a highly flexible system with maximum force transmission from the machine spindle to the customer's workpiece, and excellent resistance to chips and coolant penetrating the connection during use," said the spokesperson.
