How to solve the problem of abrasion of radial drilling machine guide rail
Relatively speaking, the technology of welding repair and adhesive repair for grinding damage of machine tool guide rail is more complex, especially the correction of large area grinding damage. Therefore, we should think about it in detail before construction.
Zaozhuang Make Machinery Co., Ltd. introduces the problems to be considered after the guide rail of radial drilling machine is worn
First of all, it is necessary to consider whether the selected correction technology has an impact on the accuracy and mechanical properties of the guide rail. For example, most of the welding and adhesive repairs need to be heated, so whether the temperature in the technical process will cause the deformation of the guide rail, and whether it will change the mechanical strength and appearance hardness of the guide rail.
Second, it is necessary to consider the adaptability of the selected correction technology to the guide rail data. For example, the guide rail of cast iron data usually does not use cast iron surfacing, because the weldability of the casting is poor, it is easy to produce cracks, pores and other shortcomings, and it is difficult to process and repair. High welding temperature, easy to cause rail deformation.
Third, we should consider the mechanical strength of the repair layer itself and the actual working environment of the guide rail. For example, we all use tin bismuth alloy stack welding to modify 4m gantry planer guide rail and T68 boring guide rail, because the former guide rail is smooth, the equipment has been used for 20 years, and the condition is still outstanding; the latter one is only three years because of poor smooth conditions and poor working environment.
