It is difficult to slot the concrete wall. The traditional way is to cut out the slot with a cutting machine first, and then remove it a little bit with an electric hammer and a pick, which is time-consuming and laborious. But now, with the advent of the new concrete grooving machine, the situation has changed a lot. The new concrete grooving machine adopts the 3100W motor imported from Germany, and rotates at a high speed of 8600min/ min, which can groove the concrete wall at one time, greatly improving the work efficiency, becoming the new favorite of the decoration market and making great progress.
