Reason: contact roller spacing trapezoidal. Solution: adjust the distance belt sander woodworking between the bracket and the lower bracket, the rotation support screw if the screw diameter is l00mm woodworking sanding machines, pitch 8mm, every adjustment 0.1, mm spacing on the circumference of the screw relative rotation distance of 314 x0.1 / 8 = 3.92mm. 5 Conclusion precision sander sanding is to ensure the quality of the premise, fine sand and grit sanding pressure plate reasonable proportion allocated to improve sanding quality is important, choose the appropriate belt can extend the life of the belt .
