Repairing spindles includes processing and disassembly, spindle assessment, grinding and other subsequent repairs, reassembly and testing for efficiency and additional maintenance procedures.
Machine spindles are part of many tools and equipment used in a wide range of industries such as the automobile and manufacturing industries. Given the wide usage of spindles by both professionals and corporations, there is a need to maintain and apply proper spindle repair. In fact, restoration of machine tool spindles has become a necessary industry. It emerged to cater to the needs of corporations that rely on machinery and equipment with spindle components. The methods used in spindle repair can be varied depending on the specifications and extent of the restoration required, but there are essential methods present. If you own machinery with a spindle or are planning to have your machine spindle repaired, it is important to be aware of the essential methods used in the repair procedure.
Processing and disassembly
Machine spindles need to be photographed and cataloged before they are completely disassembled. This information is necessary for logging and tracking the changes made to the spindle. After the processing step, the spindle may then be disassembled.
Spindle assessment
Machine spindle assessment includes closely inspecting the spindle and its parts. Each part and component of the spindle such as the spindle housing, end caps, spindle pulleys, collar locks, shaft and spindle taper and other elements are examined and accounted for. The assessment step also involves measuring and recording every component accurately in order to determine dimensions that are in need of tuning and other configuration.
Grinding and other subsequent repairs
The grinding step makes use of equipment specifically designed to modify the dimensions of the surface of a metal piece. Grinding is meant to fine tune the machine spindle measurement back to the default dimensions set by the factory or by the Original Equipment Manufacturer--OEM. By grinding, the spindle is restored to its original state and the owner is spared from the expense of having to buy a new spindle. There might also be a need to subject the spindle to subsequent repairs such as machining and bearing replacement.
Reassembly and testing for efficiency
After the previous steps have been conducted, the machine spindle is then reassembled and then tested. This step helps make sure that the repaired spindle is efficient and has been restored to almost brand new condition.
Additional maintenance procedures
There are additional maintenance procedures that can be performed on the spindle to complete the repair methods. These extra services include acoustic and stability control as well as vibration evaluation. Stability control is designed for large grinding systems and is meant to fix any discrepancies by injecting a coolant fluid to 3-4 compensating tanks. On the other hand, vibration analysis is used to diagnose problems in tools like drive motors, work head spindles, wheel head spindles, hydraulics and drive motors.
Because of the technical nature of the application of spindles in many industries, proper maintenance and repair of this essential component is important to ensure longer service life and efficiency. Accurate spindle repair also helps professionals and manufacturers prevent damages and save on costs.
