Choosing a CNC

Buying and building a new CNC (view FANUC CNC parts) can be challenging and often nerve-racking. Regardless of which space you’re in, downtime needs to be avoided as much as humanly (or robotically) possible.  Check out our points to avoid common CNC issues.

One of the most common reasons for CNC downtime would be low build quality. Balls screws,  linear guides, and linear boxes need to be built with high quality to avoid downtime. Often, unfortunately, CNC machines are built using several high-quality parts, and a handful of cheaper, lower-quality parts. Although a machine may consist of mainly high-quality, top-of-the-line parts, issues are still likely to occur due to the low-quality parts. A CNC machine, like most pieces of machinery, is ‘only as strong as its weakest link’.

By taking a look at the tool changer’s location, you can usually determine if its location will be an issue or not. Faulty tool changer designs are common in the CNC world. If it’s hard to get to the tool changer to, for example, change and replace the cam followers, then another design alternative may be best. Don’t be afraid to research other up-to-par designs and designs that have worked well for others in the past.

Avoid poor-quality spindles at all costs, as they’re everywhere and often result in issues. Take a good look at the spindles’ bearings. If they’re plentiful and look larger-than-average, you’re good to go. If they’re lacking in size, research instances where spindles’ bushings have been an issue to create your standard. Along with that, take a look at the horsepower of them; if their horsepower is below average, avoid at all costs. Stalling may occur with low horsepower spindles, which often results in many others with other parts on top of the spindle. Also, be sure to check out our article focused on maintaining automation machine tools. Maintenance is unavoidable and compiling maintenance with unnecessary rebuilds is unpractical and will likely result in downtime and lost profit.

Tolerance of CNCs should be tight. The tighter the tolerance, the longer the life expectancy generally is. Tighter tolerance will also result in an overall smoother operation. MRO Electric and Supply has new and refurbished FANUC CNC parts available. We also offer repair pricing.
