Description

Technical Field

[0001] This utility model relates to a tailstock of a CNC lathe, specifically a tailstock of a slant bed linear guide CNC lathe, belonging to the field of CNC lathe technology. Background Technology

[0002] A machine tool tailstock is a component installed on the machine tool worktable to support and fix the workpiece. The tailstock is usually used to support the other end of the workpiece to ensure that the workpiece remains stable during the machining process. It is equipped with a center point to support the workpiece.

[0003] However, different types of workpieces require adjustment of the position of the ejector head to ensure accurate contact with the workpiece's axis. In traditional methods, workers need to adjust the disc behind the tailstock to control the forward and backward movement of the ejector head. Adjusting the height of the tailstock requires workers to adjust the adjusting bolts below the tailstock, which is time-consuming and labor-intensive. Because the accuracy is inconvenient to adjust, it is easy to cause errors in the machined objects. To address these issues, we provide a tailstock solution for slant bed linear guide CNC lathes.
