CNC Machine Breakdowns and Repairs
Industry 5.0 is about automating the manufacturing lifecycle which can be achieved using CNC machines with higher precision levels providing unparalleled accuracy and efficiency. Mostly CNC machines are robustly built so it takes a lot to cause critical damage. However, CNC machines require a regular CNC maintenance service to ensure they run smoothly. If the machine is not under regular CNC maintenance it can cause disruptions and breakdowns causing potential challenges and costly downtime.
What are the potential reasons for CNC machine Breakdowns?
CNC machine breakdown can be due to common breakdown issues such as mechanical malfunctioning or issues in the G-code. To troubleshoot and start with CNC machine repair it is important to understand the cause. Let’s take a look at various reasons causing CNC machine breakdown
Machine Tool Failure
CNC machines are heavily dependent on the tools deployed for Cutting, milling, lathe, grinding, and other functions. Machine tool issues in CNC machine breakdown often arise from wear and tear, improper lubrication, or blockages. In a CNC Machine if the Spindle stops during the cutting cycle it can lead to a breakdown, similarly, if there is Hydraulic oil leakage from the cylinder or issues with Tool clamping or Turret indexing chances of the CNC machine breakdown increase. Although CNC machines are built in a way to withstand high heat if there is a coolant system malfunction and the machine crosses the tolerance limit it can lead to a CNC machine breakdown. To avoid CNC machine breakdown due to machine tool failures it is of much importance to have regular CNC machine services to keep track of underlying CNC problems. Regular CNC machine service will also help in the regular inspection of crucial components like spindles, cylinders, motors, and circuit boards. It will ensure proper lubrication of components and remove blockages promptly.
Electrical Faults
In a CNC machine Electrical faults can stem from inconsistent power supply, sensors, or faulty wiring. Common electrical issues leading to CNC machine breakdown can be Feed override, switch tripping, Sensor malfunctions, or Non-functional edit keys. To Avoid a CNC machine breakdown regular checks of wiring, connections, sensors, and circuit boards must be done and it must be ensured that there is a consistent power supply for the CNC machine
Programming Errors
A bug in the G-code or improper setting of tool paths can lead to collisions, tool damage, or operational failures. To avoid CNC Machine breakdown, the CNC machine operator & programmer must double-check code for accuracy and should verify tool path settings to avoid inaccuracies.
CNC machine maintenance negligence
Leniency and negligence in performing routine CNC machine maintenance increase the likelihood of unexpected breakdowns. Regular machine health checks and timely repairs are crucial. Many companies with CNC machines are now buying AMC’s for CNC Machine maintenance where they can get a regular machine health check-up, repair crucial components, and enjoy the benefits of preventive maintenance
Environmental Factors
Apart from all the above-mentioned reasons environmental factors also play a part in the longevity of a CNC machine. Excessive moisture, heated arena, and other improper environmental conditions can cause corrosion, electrical shorts, and other issues.
