The precision of CNC wire cutting is very high. Wire cutting machine tool is one of the indispensable equipment for precision hardware processing enterprises. The aluminum material has its own characteristics
Point, it will be difficult to cut. Wire breakage and workpiece deformation are easy to occur when wire cutting aluminum parts. Here are two problems
Talk about the solutions to such problems encountered by precision machining enterprises. In order to solve the problem of wire breakage during wire cutting, feed blocks for upper and lower wire racks are adopted
The position of the feed block shall be properly adjusted to prevent the phenomenon of wire clamping and wire breaking caused by the worn groove of the feed block, which may cause low precision machining efficiency
The material waste caused by the repeated cutting of the working surface and the decline of the quality of precision hardware processing parts occur.
In actual operation, if the thickness of the material to be machined exceeds 40mm, the feeder block will be rotated for 3 or 4 hours after machining
Angle, and rotate once more in the middle, which can effectively reduce the probability of wire breakage. So as to improve the economic benefits of precision machining enterprises. Processed
In the process, when the dimensional accuracy of precision hardware processing parts is required to be high, the diameter of aluminum wire must be measured first, and compensation and modification must be made in time
To ensure the dimensional accuracy.
The solution to the deformation of precision hardware processing: Before cutting, the machined parts should be effectively heat treated to eliminate
The internal stress of the material, so that when cutting, there will be no significant deformation, which can effectively maintain the dimensional stability of precision hardware processing parts.
When processing the outer contour, it is usually possible to cut in from the outside of the blank without piercing the wire hole, which is easy to cause material
The internal stress of the workpiece will be released, which will lead to the deformation of the workpiece, thus reducing the accuracy of the part processing
For the occurrence of the phenomenon, the method of piercing the wire hole can be adopted, which can maintain the closeness of the blank contour and reduce the stress and deformation in the process of precision machining
The generation of phenomena. When machining parts with high precision requirements, the secondary cutting method should be used for cutting.
