  • Probing Small: A 3-Step Success Checklist

    Probing Small: A 3-Step Success Checklist

    The Micro-Probing Success Checklist  Stylus performance is non-negotiable. Here is how to ensure accuracy when using styli with diameters of 0.5 mm or smaller. Working with micro-styli requires a shift in mindset. When your stylus tip is smaller than a grain of salt, standard operating procedures can lead to broken tips. To ensure your 0.5 mm (or smaller) styli perform perfectly, follow this Q-Mark verified protocol: Verify Your Probe System Capability: Ensure your probe head is rated for the low touch forces required for micro-styli. High-force modules will likely damage the stylus. Use a Small (8.0 mm) Calibration Sphere: Large calibration spheres can be difficult for micro-styli to touch all over without shank interference. A smaller 8.0 mm sphere provides the necessary clearance for dependable qualification. Lower Dynamic Probing Force: Reduce your dynamic probing force to 20% or less of your standard setting. This will help protect the stylus.   Shop Micro-Styli   Questions? Give us a call at 1-949-457-1913 or just reply to this email. Our experts are ready to assist!

  • Quick ID: Which Adapter Plate is Which?

    Quick ID: Which Adapter Plate is Which?

    Get the right one, every time. We know that keeping your equipment running is a priority. Nothing slows down a project like receiving a replacement product that won’t work. Sometimes this occurs with XXT adapter plates. While they look similar at a glance, the secret to identifying them is in the position of the carbide spheres on the top surface. Here’s a quick guide that can help you identify the right one for you.   The Sphere Test To properly identify your plate, look at the arrangement of the carbide spheres on the surface where the plate attaches to the XXT probe head. TL1 XXT-ID Adapter Plate: Note the side-by-side, stacked position of the two carbide spheres at the 12 o'clock position. This plate fits TL1 probe heads.  TL3 XXT-ID Adapter Plate: Note the space between the two carbide spheres at the 12 o'clock position. This plate fits TL3 probe heads. Using the incorrect plate can lead to error messages and delays. Pro Tip: If you’re still unsure, snap a quick photo of your current plate and reply to this email. Our team will identify it for you right away.    Need a Replacement? Now that you’ve identified your plate, you can shop adapter plates here: Shop TL1 Plates Shop TL3 Plates   Questions?
