Processing Tools and Depth of Grooving
1) Appropriate processing tools are very important to the processing quality of ALUTILE panels. For example, the blunt cutter is prohibited to use for panel processing because when it works at high rotating speed, the temperature created on the panel surface will increase up to more than 100 ℃ , which could easily make the panel materials to be molten, as a result, the quality of the finished panels will be impaired to a big degree.

2) Please use dentiform saws or some shearing tools to cut panels, instead of the grinding wheel. Also, files should be adopted to polish the cutting edges, because it will not cause a high temperature that will do harm to the coating of panels.
3) Note that don't groove so deeply to the panels, in other words, do not damage the aluminum skin at the other side. Also, don't cut off the polyethylene core layer thoroughly when grooving and leave about 0.1-0.6mm thickness.
