Diamond Sphere Styli Diamond sphere styli are steadily increasing in popularity among CMM users. Q-Mark is pleased to offer precision diamond styli in nearly any standard thread size and configuration. Diamond styli are an excellent choice for demanding applications. Their...
Cube Squared Q-Mark clients are creative. They constantly offer us ideas for new or improved products, ideas that spring from real-life, on-the-job issues. A prime example is the Cube Squared (Fig. 1, above), a hand-held gadget that squares adapter plate...
Cylinder Styli Cylinder styli are used to measure edge features, like sheet metal edges, stampings, or thin lands between grooves. We manufacture cylindrical styli from stainless steel, carbide, and ruby. They are available in all thread sizes. We have a...
Electrically Conductive Styli Many probe systems use a mechanical switch to sense when they “touch” a surface. A few, however, rely on an electrical signal to confirm contact. These probe heads use electrically conductive styli. Q-Mark makes a full selection...
Small Calibration Spheres Small diameter calibration spheres are essential when qualifying small diameter styli. They allow the stylus to reach more of the sphere’s surface, giving better qualification values. They also reduce the possibility of “shanking out” the stylus during...
Q-MARK THREAD CARD End the guesswork over the correct thread and ball sizes for your probe system. Our thread card has ten tapped holes between M2 and 3/8”-24 to check the thread size, and ten holes ranging from 1.0 to...
SILICON NITRIDE BALLS What is silicon nitride? Silicon nitride is an extremely hard hybrid ceramic (Si3N4) with a very low coefficient of friction. It’s used in high-speed spindle bearings and aircraft flap actuators to provide longer service life in demanding environments. Why...
ULTRA-LIGHT STYLI Ever-increasing accuracy requirements are driving probe sensor technology to higher levels of sensitivity. In many cases, this drive has reduced the amount of stylus weight that a probe sensor will tolerate. Q-Mark has responded to this need by...
Disk Styli Disk styli are used to probe interior grooves. The fascinating thing about disk styli is that there are seemingly no two alike. As part geometry varies, so do disk stylus dimensions. We get requests for custom disks, like...
