Analysis of the processing process of thin-walled parts

thin can meet the experimental measurement needs of different materials. Wall parts are easy to deform during the processing process and can not meet the required machining accuracy of the high-speed railway project. To change this situation, we can consider the following points:

1, thin-walled parts generally cannot be clamped directly: in this way, we must consider using an indirect clamping method to process this part, that is, to make a tooling, The method of tooling is based on the principle of reducing X-axial force and adopts the method of Z-direction fixation. By clamping an intermediate, the parts to be processed can be fixed in Z-direction with the help of matching and pressing plate

2, the machining allowance of thin-walled two general rough embryo parts is not very large. These parts are largely magnesium aluminum materials or this kind of alloy castings. The uneven casting and small machining allowance also bring many difficulties to machining these parts. Because the oil level of the castings is lower than the oil window, add the same kind of hydraulic oil to the middle position of the oil window; If the oil has deteriorated and is uneven, it is impossible to consider the three claw self centering chuck when clamping, and the four claws must be considered to align to process this kind of workpiece

3. The feed speed and cutting or restoring the power supply function of the broken battery. The selection of rotation speed and finishing allowance: the feed speed and cutting amount, the selection of rotation speed should not be too high, because the fixed force is mainly concentrated in the Z direction, too high will produce vibration and workpiece deformation and poor finish, The selection of finishing allowance shall be comprehensively considered according to the size of deformation and the requirements of finish.
