The system cuts up to four grooves simultaneously in one throughput into doors, door blanks or HDF/ MDF/chipboards and grinds off possible protrusions of the resulting contour in a further processing step. The components can be processed in longitudinal and transverse throughput.
The system is operated as a stand-alone machine and is loaded and discharged by an operator. Other options for loading and discharging are employing robotics technology or integrating the plant component in a manufacturing line. The existing database connection transfers the required process parameters by means of a barcode scanner.
The setting of groove distances and cutting depth is fully automated using positioning drives. In terms of production technology, a size-1 batch is possible without presenting any problems. To balance tolerances in the raw material the groove cutting units are resiliently mounted.
The machine operator scans the product to be processed and the machine adjusts to the preset process parameters without requiring any further effort. After the machine operator has placed the product onto the roller table, it is automatically conveyed to an alignment stop. The feed roller conveys it through the resiliently mounted cutting units. Subsequently, another feed roller conveys the product through the grinding units.
According to the customer’s wishes, the system can be operated with or without grinding. Now the component is conveyed to the removal position, where it is removed by the machine operator and stacked on a lifting table.
