5 Skills of Fixing CNC Engraving Material
How to fasten CNC engraving material?
We can study from the following techniques.
1). First protect carved materials:
2). To those processed pieces of irregular shape, on the surface it looks like the items have been fixed very solidly, but they shake back and forth when received Downforce. At this time you could put some scrap materials under the working pieces to increase the friction, besides keep the workpiece original own packing.
3). If machining materials get very big Downforce, you could consider to use tapered router bits. If cutting bits receive too large strength while moving during engraving cutting, the side force will make worked material move. If apply unsuitable cnc router tools, it happens too.
4). Because cnc machine tools are often configured with multi-functional tongs or chuck, while they are made of iron, therefore it is easy to damage carving materials or let it slip during machining process. Then selecting some rubber hats or rubber tubes could help a lot.
5). For plastic pattern relief carving, you could stick adhesive tape on the back of processed workpiece, then spray liquid glue on the side of the tape; afterwards, paste it on an unwanted surface, so could avoid leaving hard-clean surface because of using double-side glue.
