The operation of cutting the surface of the workpiece with a file to make the workpiece reach the required size, shape and surface roughness is called boring. The boring precision can reach 0.01mm and the surface roughness can reach Ra0.8um.
Boring has a wide range of applications for boring planes, curved surfaces, outer surfaces, bores, grooves, and complex shapes. You can also assign keys, make samples, and repair the geometry of the entire part.
The method of plane squatting is: forward é”‰, cross é”‰, push é”‰, etc.
1) Forward é”‰: Forward é”‰ is the most common method of boring. The direction of the boring movement is consistent with the direction in which the workpiece is held, and the plane with a small area and the final glare are all used in this way. Straight é”‰ can get a straight scar, more neat and beautiful. Fine ten is often used.
2) Crossing: The file is approximately 35 degrees from the workpiece clamping direction and the scar intersects. When the cross is twisted, the contact area between the file and the workpiece increases, and the file is easy to grasp. Crossovers are generally used for roughing.
3) Pushing: Pushing is generally used to slash the narrow plane and use it when the boring tool is blocked. Pushing can not be used to give full play to the strength of the arm, so the cutting efficiency is low, only when the machining allowance is small and the size is trimmed.
