Medium wire cutting is a processing method that reduces the error caused by material deformation and moly wire loss through multiple cuts, and its processing quality is between high-speed wire walking machine and low-speed wire walking machine. The accuracy and roughness of middle wire cutting are important indexes to measure its machining performance.
The accuracy of medium medium wire cutting:
The accuracy of wire cutting is usually within ±0.003mm, depending on the processing conditions and material thickness. For example, on a 40mm thick material, the tolerance for the dimensional limit deviation of the longitudinal and horizontal profiles is ±0.008mm and the dimensional difference is 0.010mm. In addition, the precision of the wire cutting can be improved by multiple cuts, thus reducing errors.
The roughness of medium medium wire cutting:
The surface roughness of medium wire cutting can reach Ra0.6μm, depending on the number of machining times and the material. For example, after multiple cuts, the surface roughness can reach Ra1.6μm. Through multiple cuts, the error caused by material deformation and molybdenum wire loss is reduced, thereby improving the processing quality.
The factors influencing the accuracy of medium wire cutting:
The accuracy of wire cutting is affected by a variety of factors, including mechanical problems (such as lead screw wear), electrical problems (such as motor aging) and so on. These problems can be solved by replacing worn parts or making repairs to improve accuracy.
