Analysis of Fault Mode Data of CNC Gantry Milling Machine

The connection with the central control board, the disconnection and restart, the system failure phenomenon has no change, the initial judgment is faulty; the connection of the upper number is set to the connection with the central control board, disconnected and connected , restart, the main and auxiliary start normal, the initial judgment of the card is normal; because of the same as the installation base plate, power module and card for address setting, remove all the cards on the board, install the power module and Fault analysis China equipment engineering subsystem failure frequency ratio, mechanical system hydraulic system electrical system total table CNC gantry milling machine subsystem failure number, failure mode downtime ratio spindle motor beam brake refrigeration system accessory failure, main pump station control system other total The impact of the downtime schedule. The main failure mode of CNC gantry milling machine downtime, the statistical analysis of the failure mode of CNC gantry milling machine, through the statistical analysis of the failure mode of numerical control equipment, determine the components of the CNC equipment that are prone to failure, and further analyze the cause of the failure, targeted Maintenance management of CNC equipment.

The statistical analysis of the failure mode of CNC gantry milling machine is based on the analysis of the two-year record data of the CNC gantry milling machine imported from West Germany. The number of failures and the proportion of each subsystem, the main failure of CNC gantry milling machine occurs in the electrical system, hydraulic system. Second, the mechanical system is the least. The equipment has been in operation for a few years (three shifts), the electrical system is aging, and the failure rate is high. The mechanical system failure rate is low and remains basically constant over the years. The reason: the complexity of the modern CNC equipment hardware is transferred to the software, simplifying the mechanical system structure; the reliability of the mechanical system is improved. Therefore, the mechanical system of the CNC portal milling machine has no obvious fault wear period. The main failure mode affecting the utilization of CNC gantry milling machine and the corresponding downtime. It can be seen that the main failure mode affecting the utilization of CNC gantry milling machine is the failure of the spindle motor of the electrical system, followed by the failure of the beam brake of the mechanical system, and again the refrigeration system and accessories.

Angle Valves

Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.

Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
