Understanding Common Causes of CNC Machine Issues

Operating a CNC machine is never an easy task. Production output must be maintained with the highest of standards with high-speed tools performing multiple tasks. A mis-measurement or timing error, even to the slightest extent, can mean the difference between a flawless production and wasting time and money.

Lack of CNC Machine maintenance

The reality of taking care of a CNC machine is not an easy one. There are more moving parts involved than you find on a Space Shuttle and all those parts have to work in perfect synchronization or the whole operation becomes a failure. It could end up being a waste of time, money, and production capacity.

For many operators, the solution is to stay organized and never depart from a strict schedule of regular and preventative maintenance activities.

CNC machine user error

Regardless of how much time an operator has in service, CNC machines change and so do their operating protocols. Training and education helps prevent problems, but user errors may still occur. The computer program could have a glitch or a tool mounting point may not be correct for the spindle. In other words, errors occur. While many user errors can be avoided with adequate training and oversight, sometimes things go wrong for no apparent reason. Troubleshooting guides can be very helpful in resolving user error problems.

Loose fittings on CNC machine

 CNC machines might sit in the same location all day long, but a lot is going on inside. Due to the amount of movement, speed, and environment in which a CNC machine performs its tasks, the connecting points between components can become loose and malfunction.

Vibration is the big enemy and there’s not much that can be done about it. The best way to deal with the problem is to physically examine each electrical, hydraulic, pneumatic, and mechanical connecting point on a scheduled basis. Records should be maintained detailing any issues that can later be reviewed with the CNC machine manufacturer’s service representative.

Heat build-up in CNC machine

Despite all the attention and engineering devoted to reducing operating temperatures for CNC machines, heat build-up is still a big problem. Fast-moving, high-speed components develop heat from friction and hydraulic lines and fittings can suffer from extreme temperatures while operating. Even pneumatic air lines can become hot and melt high-pressure hoses.

Regular and thorough filter maintenance helps reduce high temps by enhancing flow capacities through heat-dissipating radiators and air-cooled pipelines. There should be constant attention being made to all thermal indicators. Finally, operators are encouraged to place additional thermometers and heat-detection equipment in problem areas.
