Selecting a Fanuc CNC

It might be tough and sometimes stressful to purchase and construct a new CNC (see FANUC CNC products on our website). Downtime needs to be minimized as much as humanly (or robotically) possible regardless of the environment you're in.  Check out our advice to prevent typical CNC problems.

Low construction quality would be one of the main causes of CNC downtime. To avoid downtime, high-quality linear guides, linear boxes, and ball screws must be designed. Unfortunately, many high-quality parts and a small number of less expensive, lower-quality parts are often used to construct CNC machines. Even if a machine may be made up primarily of top-of-the-line, high-quality elements, problems are still likely to arise because of the low-quality parts. Like other machines, a CNC machine is only as strong as its weakest link.

You can typically tell if the tool changer's position will be an issue by looking at where it is. In the field of CNC, flawed tool changer designs are rather frequent. Another design choice would be preferable if accessing the tool changer to, say, remove and replace the cam followers is difficult. Don't be hesitant to look at other excellent ideas and concepts that have previously succeeded for others.

Poor-quality spindles should be avoided at all costs because they are common and can cause problems. Examine the spindles' bearings thoroughly. You're okay to go if they're numerous and appear larger-than-average. If they are too small, find examples where the spindles' bushings have caused problems to develop your standard. Additionally, examine their horsepower; if it is below average, avoid it at all costs. Low horsepower spindles are susceptible to stalling, which frequently leaves several other components stacked on top of the spindle. It is impossible to avoid maintenance and combining it with pointless rebuilds is impractical and likely to lead to lost time and money.

CNC tolerance needs to be very tight. In general, life expectancy increases with minimal tolerance. A smoother functioning will also be the outcome of tighter tolerance.
