I'm ready to replace my laser cutting table with a honeycomb grid but need some advice. The table I currently have is about 1" in thickness aluminum and two different styles of table surface, flat 1" wide strips and thin rails on the opposite side of table with a triangulated webbing (see picture below). When I'm cutting sheet acrylic I found that I really could do better with a honeycomb table because my table creates to much flash back causing small points of stress and dots of super heated resin along the edges creating a cleanup issue.
My table size is 600mm X 900mm or slightly smaller than 24" X 36". The support structure is made from angle iron like a bed frame with about 1" lip all around for placing the table on. There are no supports within the field, ie no cross members in this table frame. I am concerned with the sag from this large of honeycomb panel.
Those with a honeycomb table can you tell me what thickness it is and if you have any supporting cross members on your table frame?
Thanks
Pete
