Tell you about the milling technology of precision parts processing

Precision parts processing is still widely involved in the industry. Why is there such a statement? In fact, we can see it in life, the effect is obvious, and there will be more applications in some mechanical equipment. The requirements for precision parts processing are also very high. Why is this? Due to the customer's requirements for product quality, and the advantages of this kind of precision parts processing itself are great, it is necessary to do better and make customers more trustworthy. This is what precision parts processing needs to do.

For the milling of generalized plane parts, the side cutting of end mills is generally used. In order to reduce the tool marks and ensure the appearance quality of the parts, the cutting and cutting process requirements of the tool are very strict.

When milling outlines the appearance of precision parts, the cutting point of the milling cutter should be cut and cut along the extension line of the outline curve of the part, not along the normal direction Directly cut parts are cut to avoid scratches on the outer shape and ensure general lubrication of the parts.

When machining the closed inner surface of the milling cutter, if the inner curve promises to be extended, it should be cut along the tangent direction. If the inner curve does not allow extension, the tool can only cut along the normal direction of the inner curve, and select its cutting and cutting points at the intersection of the two elements in the workpiece. In the case that the inner number is tangent and has no intersection, in order to avoid the withdrawal of the blade, a groove is left on the cutting corner of the blade, and the cutting point should be far away from the cutting corner of the blade.

Describes the tool path for milling the outer circle by circular interpolation. At the end of the rounding process, the tangent points cannot exceed 2, and the tool should travel a distance along the tangential direction to prevent the tool compensation from being cancelled, and the CNC lathe tool contacts the surface of the workpiece, which constitutes the failure of the workpiece. When milling the inner arc, the optimal organization form of tangential tangent and arc to arc transition should also be followed, so as to improve the machining accuracy and machining quality of the inner hole surface.
