A CNC router machine is a pricey investment for a Stone Fabrication Shop and often a critical decision for any factory. A machine’s durability determines its frequency of maintenance, downtime, and expenditures, which impact the profit inflow of the company. Therefore, you must never overlook the timely maintenance of your CNC machines.
It is recommended to perform routine maintenance checks on the machine to ensure better uptime and productivity. Appropriate implementation and maintenance of CNC machines can avert catastrophic machinery failures and ensure longevity with barely any downtime.
5 Tips to Maintain the Stone CNC Router
Most machinists and factory owners often overlook the timely maintenance of CNC machines until it starts affecting their working and stability. Daily maintenance checks can help prevent downtime and save costs in the long run.
Follow these five tips when performing timely maintenance checks of a stone CNC router to ensure its longevity during operation hours –
1. Maintain Cleanliness
Sweep and clean the table every time you operate the machine by washing the mud (dirty stone water) with clean water and blowing the dust away using an air gun. Messy surroundings lead to the buildup of dirt and debris, which enter the lubrication system and halt the machine’s operations.
Keep the lead screw clean to block foreign substances from lingering on it. The screw is utterly crucial, as it determines the machine’s accuracy and plays a significant role in the transmission process.
Do not overlook cleaning the industrial control box regularly since dust is the greatest killer of the circuit board and can cause a short circuit. Clean out the dust collected on the platform and the transmission system.
Filters must get cleaned regularly, and timely replacements must be done. Dirty filters can cause poor heat dissipation and malfunction.
2. Maintain Ideal Surroundings and a Controlled Environment
Estimate the applicable temperature of the fueling standard to at least the minimum temperature. If you are not yet using the CNC machine, which is kept in an environment with exceedingly low room temperatures, it is advisable to pour out the water stored in the tank so that the tank and water pipe do not crack.
Several operators add butter to the screw and skip cleaning up during winters, which puts pressure on the machine upon starting up. Some workrooms have significantly low temperatures, due to which the added oil can still get frozen.
Maintain minimal humidity levels in the operation room to prevent rapid wear and tear, poor electrical contact, and short circuits of electrical accessories of the CNC machine.
It is also crucial to note the electromagnetic interference in the operation room. If the interference value is enormous, the machining accuracy plummets. CNC machines must also be kept away from the apparatus that creates high vibration to block interference.
3. Frequent Lubrication
CNC machines require frequent lubrication to ensure seamless functionality and avert premature wear. Each component of a CNC machine, including the lead screws, the spindles, the guide rails, tool holder, bearings, and sliders, demands timely and appropriate lubrication to dampen the wear speed.
You must stick to the manufacturer’s recommendations and go for grease or oil. Improper lubrication can make the machine parts stick together or restrict their movements, causing further problems.
Begin by cleaning the guide rails and lead screws and then using a rag to wipe off the oil and material debris collected on them. During low temperatures, consider adding oil to the lead screws and rails.
If you have not used the machine for prolonged periods, it is advisable to have it refueled regularly to maintain the transmission system’s flexibility. Upon adding the oil successfully, move the component back and forth slowly to ensure that you evenly spread the lubricating oil to the lead screw and the guide rail.
4. Regular Inspection
Ensure the reliability of the moving components of the CNC machine each month, especially the drivers, motors, and fixing screws. When conducting daily inspection checks of the CNC machine, have the power disconnected, hold on until the monitor goes blank and the main circuit power indicator has been cut off.
Damaged CNC tools and parts can negatively impact cut accuracy and quality. Therefore, you must inspect the working condition of CNC cutting tools, collets, tool holder, tool holder forks, CNC suction cups, table gaskets, jigs and ensure timely replacements.
5. Cooling Water for Spindle Motor
Cooling water is undoubtedly critical for the water-cooled spindle motor. Dirty cooling water can cause significant damage to the motor. You must never dehydrate the water spindle motor and ensure regular replacements of the cooling water to prevent surging water temperatures.
During winters, if the working environment temperature drops substantially, the water in the tank can get substituted with antifreeze. Closely monitor the water level and never dehydrate the water-cooled spindle motor. Otherwise, the motor heat will fail to export in time.
Yet another parameter to monitor closely is the ambient temperature. You must be careful since the water temperature is exceedingly low and can freeze the water tank and water pipe. Instead, you can use antifreeze for cooling.
It is common knowledge that machines demand regular maintenance, and the stone CNC router acts similarly. Regular maintenance is crucial to ensure the longevity of the CNC machine and minimize downtime.
Keep the machine’s surroundings clean, maintain the ideal ambient temperature, perform timely inspection, and more to keep your machine from breaking down during operation.
