The fitter file is mainly used for filing or repairing the surface and holes and troughs of metal work pieces. According to the cross-sectional shape is divided into flat file, pointed flat file, square file, triangle file, semi-circular file, round file; according to the density of the main file, file grain number is divided into 1-5, of which 1 is the thickest, 5 is the finest. In the use of these tools, often appear file file uneven situation, file uneven reasons, mainly because:
The problem with our tools, the plane of the file is poor, there is distortion or a gap, if this is detected, we have to change the file!
The second situation is our own reasons, the file position is not correct, we must grasp the body and the pliers parallel line is 45 degrees, the left foot and the pliers in the vertical line is 30 degrees, the right foot and the vertical line is 75 degrees angle. The distance between the left and right feet is 250mm ~ 300mm from these four angles, and the elbow to sink, hand-foot coordination to coordinate!
The third requirement is the operation of the reason, the left and right hand force to balance, to ensure that the file into a parallel linear movement, when the end of the file, must make the file stop 3, in the flat end of the file, so you can easily file flat!
If there is a file uneven situation must be a profound reflection, their fitter internship during the operation and habits of the formation, there is their own "weapons" tool file maintenance and maintenance!!
