The Common Tailstock Runout Problem of Spinning Machine 1.The tailstock of spinning machine tool is easy to runout. The following are the main reasons for the tailstock of machine tool to runout. 1)The roller hit the tailstock shaft, resulting in the deformation of the tailstock shaft. 2)The precision fit between the tailstock and tailstock shaft is not high enough. 3)The tailstock shaft bearing is worn and damaged, and there will be abnormal sound when the tailstock shaft rotates. 4) Spindle mold and flange assembly precision is not good, lead to the tailstock runout. 2. What is the impact of tailstock runout of spinning machine on spinning products? The tailstock runout of spinning machine will have a certain impact on spinning forming, mainly due to the following factors: 1) Stainless steel due to the material elongation rate is not good, the force is large, when the tailstock runout will be due to the uneven force of the material root fracture. 2) The hardness of aluminum is low, and the spinning process will scratch the bottom of the spinning product due to the tailstock runout. 3) Tailstock runout will cause the contact area between the sheet and the tailstock is not enough, and the spinning force will make the sheet move. 4) The tailstock runout will affect the dimensional accuracy of the product after forming, and the diameter accuracy of the bottom of the product will become worse. 3. The main reasons for the sticking of the spindle of the spinning machine in the process of powerful spinning 1) The mold has not decrease weight ,and the mold is too heavy. 2) The belt of the spindle motor becomes slack after being used for too long, and adjust the pre-tightening force can be solved.
