1.   ，开齿操作之前，要先将开齿机进行调试，然后进行开齿。

Firstly, before the gear opening operation, the gear opening machine should be debugged first, and then the gear opening should be carried out.

2.   其次，开齿机的冲头及冲模必须锋利，并要咬合一致，间隙小于0.1毫米。假如冲头不锋利，则锯齿容易发生裂口和变形，尤其比较薄的锯条容易发生扭曲这样的冲头应该立即修磨。假如这样的冲头开齿，应用锤子修平锯齿，防止锯切时跑锯。

Secondly, the punch and die of the gear opening machine must be sharp and have consistent bite, with a gap of less than 0.1 millimeters. If the punch is not sharp, the saw teeth are prone to cracking and deformation, especially for thinner saw blades that are prone to twisting. Such punch heads should be immediately ground. If such a punch has teeth, use a hammer to smooth out the serrations to prevent the saw from running during cutting.

3.   锯条开齿时，锯条必须呈水平状态，其表面要与开齿机冲头的冲压方向垂直，不得倾斜。同时锯条边缘要与导轨平行，开齿后的齿距，齿高应均匀一致。

When the saw blade is toothed, it must be in a horizontal state, and its surface must be perpendicular to the punching direction of the toothed machine punch, without tilting. At the same time, the edge of the saw blade should be parallel to the guide rail, and the tooth pitch and tooth height after tooth opening should be uniform and consistent.

4.   锯条开齿时，如果手工开齿器应留出1~1.5毫米的研磨余量，如果使用自动开齿机可留出0.5~1毫米的研磨余量，过大过小都会浪费锯条和砂轮。当开齿机不能按规定开齿时，可加大研磨余量，再用磨锯机研磨出正确的齿形。

4. When using a saw blade to open teeth, a grinding allowance of 1-1.5 millimeters should be left for manual tooth openers. If using an automatic tooth opener, a grinding allowance of 0.5-1 millimeters can be left. Both too large and too small will waste the saw blade and grinding wheel. When the tooth opening machine cannot open the teeth according to the regulations, the grinding allowance can be increased, and then the correct tooth shape can be ground with a sawing machine.

5.   如果带锯条有硬度高的烧斑部分，则烧斑部分的开齿比其他部分要浅，在研磨齿形时，对于烧斑开齿部分，要多加研磨，以使齿高整齐。如果烧斑部分开齿很深，锯齿容易折断。

5. If the saw blade has a high hardness burn spot, the open teeth of the burn spot are shallower than other parts. When grinding the tooth profile, more grinding should be done on the burn spot open teeth to make the tooth height neat. If the burnt area has deep teeth, the serrations are prone to breakage.

6.   我们在操作工程中，如发现齿底，齿喉，齿背部位出现碎裂，凹陷和锯齿弯曲等不正常情况时，应立即停止操作，认真查找原因。

6. In the process of operating the project, if we find any abnormal conditions such as cracks, dents, or serrated bends at the bottom, throat, or back of the teeth, we should immediately stop the operation and carefully investigate the cause.
