Q: What's the difference between M3 and XXT products?
A: M3 products use 4.0 mm diameter stainless steel bases and fittings with carbide or ceramic shafts. XXT products use 5.0 mm diameter titanium bases and fittings with carbide or graphite shafts. XXT products weigh less than similar M3 products.
Q: How do I tell the difference between TL1, TL2 / TL4 and TL3 XXT Adapter Plates?
A: The carbide spheres on the top of the plate are in different positions. See illustrations, below:
This is a TL1 adapter plate. Note the side-by-side position of the two carbide spheres at the 12 o'clock position. This plate fits TL1 probe heads.
Q: What is the best sphere material choice for my application?
A: Ruby spheres have long been the industry standard, thanks to their high hardness, excellent spherical form, low coefficient of friction, relative low cost, and good abrasion resistance. We recommend using ruby spheres for most measurement tasks.
That said, there are certain applications where we recommend spheres made from other materials.
Silicon nitride spheres exhibit superior performance when measuring untreated aluminum and brass. When a ruby sphere repeatedly touches a soft material, bits of the material will adhere to its surface. Silicon nitride resists material buildup. Silicon nitride is also a better choice for abrasive surfaces, like high temperature alloys and EDM cuts.
Zirconia spheres are best on cast iron. Cast iron can quickly wear out a ruby sphere.
Diamond spheres are the best choice for any material. Diamond spheres never wear. Soft materials won’t adhere to a diamond sphere. Bonus: diamond spheres won’t scratch. Not even a mirror finish.
Q: How do I know which thread size to order?
Q: What is the thread size on Q-Mark's calibration spheres?
A: All calibration spheres have M6 threads.
Q: What should my Dynamic probing force be when qualifying very small styli?
A: For qualification of miniature styli sizes 0.5mm and smaller remember to also lower your Dynamic probing force (in %) to 20% or less. This along with lowering your Probing force (in mN) will keep you from breaking your styli tips during qualifying.
Q: How do I qualify very small styli?
A: There are three steps.
1. First, verify that your CMM’s probe system has the capability to use styli with spheres that are 0.5 mm or less in diameter. Certain probe systems aren’t compatible with very small styli.
2. Always use a small calibration sphere. We suggest 8.0 mm diameter.
3. Adjust the probe force to the minimum level. Lower the dynamic probing force to 20% or less, if possible.
Follow these three steps and you’ll achieve successful and consistent qualification of delicate styli. If you have any questions, please feel free contact our experts at firstname.lastname@example.org. We’re here to help.
Q: How do I qualify a disk probe?
A: Take at least 12 probings all over the disk. For example, take 4 points around the equator. Then move half the distance to one edge, and take 4 more all around. Move to the opposite side and take 4 more all around. Compute the result. If the standard deviation is too high, start over, taking more points.
Q: When should I use a cylinder stylus?
A: Cylinder styli are best suited for measuring edge features, like the edges of stampings, sheet metal, or thin lands between grooves. A sphere stylus is always a better choice than a cylinder stylus for everyday measuring tasks.
Q: How do I qualify a cylinder stylus?
A: To calibrate your cylinder stylus you must reduce the calibration sphere coverage angle so that the spherical end of the cylinder stylus is always above the equator of the calibration sphere. We recommend a coverage of 150 degrees. Now proceed with the calibration routine. Please note that the form of the spherical end on a cylinder stylus will never be as precise as a spherical (ball) stylus. Expect a higher standard deviation value when qualifying a cylinder stylus as compared to a spherical stylus.
After calibration, it is important to measure a known artifact, like a ring gage, to ensure that the result is within acceptable limits. Sometimes it's necessary to adjust the calibration results to get the correct measurement from the artifact. Only when you are satisfied with the results from the artifact should you proceed with inspection.
Q: How do I open packaged styli?
A: Packaged styli can be very small and fragile. Opening the package incorrectly can damage the contents. Watch the video below to learn how to - and how not to - open our packaged styli. The correct way to open a packaged or mini styli is to open the package carefully by holding the red holder in one hand and carefully pulling the styli directly out of its clear case in a parallel motion like taking a sword out of its sheath or a lipstick out of the case. This prevents the delicate part from breaking.
