jafuji granite surface plate (with nabl calibration,jafuji granite surface plates are inspected through electronic level and computer provided with “wyler measuring & processing system “of m/s.wyler switzerland, to ensure the accuracy. jafuji granite surface plates are supplied with a calibration certificate traceable to national standards showing graphic display of the flatness..why granite surface plate calibration is important,a surface plate that is calibrated will present a high degree of flatness and stability, ensuring a level surface to work with so accurate workmanship can be achieved. while calibration should be performed regularly to maintain its flatness and measurement accuracy, there are other things you can do to ensure you’re providing the best care possible for your plates. tips for taking care of your granite surface plates: – keep the plate cleaned – cover the plate.
What Can I Do For You?
granite surface plate calibration is best provided by experts. repair of surface plates is an art form. our master surface plate technicians have many years of experience with all types of granite and wear. for a detailed discussion in professional granite surface late calibration and repair see our white paper.
users can calibrate a granite surface plate to ensure its accuracy. clean the granite surface plate prior to calibration. pour a small amount of surface plate cleaner on a clean, soft cloth and wipe the surface of the granite.
granite surface plate calibration typically also includes cleaning and light polishing of the gaging surface. the overall flatness is often checked with a laser interferometer, autocollimator, electronic levels, or master straightedge and indicator. for all of these methods, a series of measurement lines are made in a grid across the surface plate.
your granite surface plate (granite block, granite table) is the foundation of all accurate measurements, optimal calibration has the ability to achieve extremely tight tolerances to ensure that your are getting the most precise measurements possible.
in practice, both the overall flatness and local variation in flatness need to be calibrated on a surface plate. calibration is done by checking conformance of the surface plate to the two different tolerance values. if necessary, adjustments to the
by the early nineties, dox calibration became one of the most recognized names for granite surface plate calibration east of the mississippi. address phone: 800-222-3528
when your granite surface plates need calibration, repair, cleaning or machining, choose the company so many industry leaders have already trusted to work on their surface plates. granite surface plates, granite squares, granite tables are the foundation upon which so many of your dimensional measurements rely.
maintaining granite surface plates. surface plate calibration is the only sure way to know that you are working with a level surface and can expect accurate workmanship when the surface plate is in use. surface plates wear over time and must be properly maintained to ensure flatness and continued precision measurement.
surface plate calibration. dimensional gauge company are the experts in granite surface plate calibration and repair. we are not a “clearing house” calibration lab. we are highly skilled specialists that can provide surface plate calibration and recertification the other labs cannot.
calibration & resurfacing of granite surface plate. your granite surface plate, in your temperature controlled inspection lab, is the foundation upon which many of your dimensional measurements are determined. selecting and caring for a granite surface plate is essential to ensuring that your product’s dimensional specifications are as accurate as
surface plate manufacturing companies generally do not make specific recommendations for surface plate calibration cycles as the right calibration cycle vary for every department depending on their volume of use and how well the granite surface plates are cared for.
surface plate calibration & surface plate resurfacing. precision granite calibration capabilities-8 to 161 inches diagonal check out our dimensional calibration page for more capabilities.. brands we calibrate:
a surface plate should be supported at three points, ideally located 20% of the length in from the ends of the plate. two supports should be located 20% of the width in from the long sides, and the remaining support should be centered. only three points can
calibration and resurfacing of granite surface plates. at optimal calibration, three precision instruments are used in conjunction with one another to determine the accuracy of a given surface plate. the repeat-o-meter is the instrument that is used to check the repeatability, or small wear spots that occur from normal everyday use.
calibration ensures your surface plates meet flatness specs for your grade, which makes accurate measurements possible. most flat surface plates are granite, and they are instrumental in your quality control department’s precise measurements.
the smooth and flat surface of granite surface plates provides an accurate reference plane for measuring and inspecting various parts during fabrication and for the calibration of test equipment. granite surface plates are used in various manufacturing plants, especially in the automotive and aviation industries, machining shops, and inspection and calibration laboratories.
granite surface plates provide a base from which accurate measurements can be taken in both shop and laboratory environments. the physical properties of the granite, such as its surface hardness, low thermal expansion, and the tendency to chip vs. dent make it a superior choice over s/b or cast-iron surfaces.
our calibration rep tells me that the outside calibration tech that we hired to calibrate our surface plate spends less than 3 minutes to calibrate the surface plate and he only cleans it. i am a bit concern over this but would like to see first hand before i bring up the issue, i have seen surface plate calibration before but it has been a couple of years and may need a refresher.
granite surface plate granite surface plates are used for precision gauging, inspection, layout and marking purposes. they are preferred by precision tool rooms, engineering industries and research laboratories because of their following outstanding advantages.

a. surface plates are supported on three points. the location is determined with a 20% formula. place them at 20% of the length and width in from the edges, with the third at 20% of the length and centered on the width. see installation instructions on the forms page of our web site. q.
users can calibrate a granite surface plate to ensure its accuracy. clean the granite surface plate prior to calibration. pour a small amount of surface plate cleaner on a clean, soft cloth and wipe the surface of the granite. immediately dry the cleaner off the surface plate with a dry cloth. do not allow the cleaning liquid to air-dry.
