Styli Ball Cleaning: Ensuring Consistency With Your CMM Inspection Results
Achieving consistent measurement and inspection results time and again is a must for many of our clients who invest in a CMM machine. Several factors can affect inspection accuracy and one of the easiest ones to rectify is the styli ball.
Often, simply due to regular use, the styli ball on a CMM will suffer from build up of dirt, contaminants and debris (examples in the images below).
If this is not cleaned away regularly and thoroughly then inspection accuracy will drop, resulting in inconsistent measurement results and potentially failing to meet quality standards. As well as this, adhesive and abrasive wear can affect a styli’s performance, these will both result in permanent changes to the ball’s composition and can’t be rectified. In this instance, a replacement styli is required.

Do you know what you checks you should be performing on your CMM machine on a regular basis to ensure it is working at its full capacity? We’ve put together a checklist for you to refer back to should you need it.
CMM Calibration And Verification Explained By The Experts
Do you know the difference between measuring equipment calibration and verification?
The two terms are often used interchangeably between service providers, sometimes leading to confusion on what each term means. It’s certainly a question we get asked a lot here at Status. Here we take a closer look at both of these terms and explain what’s involved with each.
What Does CMM Servicing & Maintenance Include?
For manufacturers working to extremely high-quality standards, such as those in the aerospace, medical and automotive industries the continued use of a CMM machine at optimum performance is critical. Downtime and underperformance of the machine can result in delayed production, unsatisfied customers, failure to meet quality requirements and potentially huge losses. To help ensure a CMM continues to operate at a high standard and to avoid any inspection bottlenecks, regular maintenance, calibration and servicing should be carried out. So, what does CMM servicing and maintenance include?
The CMM Calibration Procedure Explained
Keeping your CMM machine calibrated regularly will ensure that the measurement data that you create is accurate. The definitive procedure for calibration of CMMs which is used by all CMM manufacturers is the ISO 10360 series. Most CMM machine calibration will be accomplished with the use of an artefact, but for more demanding calibration, a laser interferometer can be employed. Ultimately CMM machine calibration comes down to one thing: precision.
ISO 10360-2 & UKAS Accredited CMM Calibration Services From Status Metrology
Quality assurance control highly depend on CMMs. Over the last 20 years, they have almost replaced other inspection techniques such as fixtures and gauges. Since CMMs are very flexible, they reduce investment costs and increase inspection throughput.
Nationally and internationally recognised performance standards provide the means for CMM users to rate the calibration services of different providers. These standards are necessary when comparing competing suppliers, to help determine how well they will perform and to check whether they know how to work properly and safely.
What’s The Ideal CMM Calibration Frequency?
Keeping your CMM measurement machine calibrated needn’t be difficult, but it is very important for your machine to operate accurately and efficiently. There are many kinds of calibration techniques, and some will be necessary more often than others. The important thing is to create a schedule for calibration, so that you don’t forget to keep your metrology sound. At Status Metrology we specialise in high quality CMM machines and calibration services, and maintain both ISO and UKAS certifications. Let us share some of our insight about CMM machine calibration, and how often you should be performing it. Read More
TR_FG018 Error Code – The Common Cause And Future Prevention
One that’s coming up a little more regularly here at Status Metrology HQ is the concerned call from a CMM Operator who’s machine isn’t performing and reporting a TR_FG018 error code. As machine environments, build quality and reliably all improve, it is human nature to expect the CMM to always be on point. However, TP20’s wear as they are swapped on and off the CMM however many times a day, week, month or year. Often as not when the touch probe isn’t seated properly or the contact surfaces are worn you’ll receive a TR_FG018 error code. Thankfully it is usually very easy to remedy, simply swap that touch probe off the CMM or re-seat the probe and ‘hey presto’ it should resolve the problem.Read More
What Makes A Good CMM Calibration Artefact?
Making sure that your CMM machine is well calibrated is an important part of keeping your measurement data accurate. There are a number of artefacts that you can use to test the calibration of your CMM machine, and they all do something different.Read More
