For depaneling, a workpiece holder is always required. The design of the workpiece holder is crucial to the milling accuracy and has a 1:1 effect on the milling result.
Workpiece holder concepts are available, depending on the panel layout, the size of the individual printed circuit boards, the component geometry, and quantities. SCHUNK is the world's only manufacturer to offer depaneling machines and flexible workpiece holder solutions from one source.
Versatile workpiece holders are always the ideal solution, if there is a large product variety with a relatively simple product layout, even for high quantities. If complex assembly groups with a demanding layout must be milled, then a specific workpiece holder from our partner Schnaidt is used.
The magnetic pins, which are in the bottom part, can be mounted with the milling spindle and a special mounting tool in the depaneling machine from SCHUNK, and placed on the workpiece holder base plate by means of separate software. The pin setting program can be easily created for each assembly group using a CAD/CAM software.
Before a product change, the pins can then be removed manually, and returned to the pick-up position for a new magnetic workpiece holder configuration.
In order to be able to cut printed circuit boards from a panel with high precision, the printed circuit boards must be held in place precisely positioning and must not move after being separated. With the Schnaidt system, optimum holding and separation of the printed circuit boards is ensured. Removal plates make it possible to quickly remove even many small individual assembly groups.
The do-it-yourself workpiece holder allows one to independently produce a product-specific workpiece holder using the depaneling machine. Due to its high performance, the spindle of the machine can also be used for drilling, allowing holes to be drilled into plastic plates. Afterwards, the pins must be pressed manually into the holes. The self-manufactured workpiece holders are used for sample production or for small to medium quantities.
