Vertical lathe maintenance * repair

Vertical lathes are large mechanical equipment used for processing large and heavy workpieces with complex shapes, with large radial dimensions and relatively small axial dimensions. Such as cylindrical surfaces, end surfaces, conical surfaces, cylindrical holes, conical holes, etc. of various disks, wheels, and sleeve workpieces. Additional devices can also be used for machining such as threading, spherical surfaces, profiling, milling, and grinding

The spindle axis of the vertical lathe is arranged vertically, and the worktable is in a horizontal plane, making it easier to clamp and align the workpiece. This layout reduces the load on the spindle and bearings, so the vertical lathe can maintain working accuracy for a longer period of time

The flat workpiece repaired by scraping and grinding vertical lathe can achieve close contact between two planes, obtain high shape and position accuracy, and the machining accuracy can reach IT7 level or above, with a surface roughness value of Ra0.8-0.1 μ m. The flat surface after scraping can form a sliding surface with a lubricating oil film, thus reducing the wear between the relative moving surfaces and enhancing the contact stiffness between the joint surfaces of the parts. The surface quality of scraping is evaluated by the number of contact points per unit area, including rough scraping, semi fine scraping, and fine scraping

Vertical lathe maintenance scraper http://www.btjxjt.com Heyan is two types of manual machining techniques used to adjust the shape, surface roughness, roundness, and other aspects of workpieces. Scrape: Use the sharp edge of a triangular scraper to remove the protrusions on the surface of the vertical lathe workpiece, making the workpiece surface smooth. Generally used for inner circle trimming of bearings, cylinder liners, etc. Research: Grinding, which can not only remove the protrusions on the surface of the workpiece to make it smooth, but also adjust the shape of the workpiece. File and sandpaper are commonly used tools for surface adjustment of lathe guide rails, shaft outer diameters, etc. The two techniques are often used together for lathe maintenance.
