JINGDIAO Proven Precision Machining Solutions
High precision hole grinding requires multiple grinding process. In addition to grinding, other operation are required, including workpiece position alignment, incoming material inspection, workpiece cleaning, workpiece remaining stock inspection etc. If these operations are completed manually, the processing will be discontinuous and the in-machine environment will be changed.
JINGDIAO 3-axis high-speed machining center can automatically run the above actions. The key is to complete the planning of processing, inspection and control programs in the software, and let the program drive the machine tool to execute, so as to ensure the continuity of machining in the machine and realize the working mode of "in-machine automation".
