One Type ：To achieve continuous cutting edge, so that light cutting to reduce the closure crop is particularly well suited to timber processing. As a result of wood, hard wood, hard materials, with the general level of such wood processing knife will not be smooth surface, phenomena of a very serious choking thorns, not the processing request, on the other hand, also significantly decreased the efficiency of processing equipment, machines appear walk phenomenon feed。
     The present utility model invention to solve the technical issues are: (1) the general level processing knife gill shortcomings choke; (2) the general level of hard wood processing knife shortcomings walk; (3) ordinary knife-ping noise processing equipment shortcomings in the processing of hard materials at feed rate of up to raise the passing rate of the product several times。
    Equipment decreased noise. The maintenance of the machine tool equipment, there are positive results. As a result of wood, hard wood, hard materials, with the general level of such wood processing knife will not be smooth surface, phenomena of a very serious choking thorns, not the processing request On the other hand, also significantly decreased the efficiency of processing equipment, there is walk feed machine。
    Two Type：Folder level spiral planing machine for planing a long flat blade cutting or planing machine sand, features: knives to reduce the cost of tool regrinding solve technical problems such as positioning。
