Epac Technology

Advantages over Caliper Saddle Mic Technology
  1. Profiling Accuracy and Reliability                                     Eliminating the drawbacks of extraneous motion and vibration inherent in saddle mics of the caliper design, the Epac 3000 is a completely rigid Roll Micrometer that, except for the wheels and gauge head probes, has no moving parts. This rigidity adds to its performance, providing both repeatability and reproducibility as verified by rigorous testing. Epac R&R tests are done in working roll shops, not laboratories.
  2. Compact Design                                                                  The smaller size gives the user the ability to physically fit into places that would have been unavailable for roll inspection, allowing the instrument to be used for thermal profiling in tight places, troubleshooting in the mill, and skating rolls without pulling them from a stack, as well as for the traditional profiling of rolls.
  3. Light Weight                                                                        Weighing in at 14.5 pounds for the backup micrometer, the lighter weight benefits the user in providing a safer instrument for the operator, dramatically reducing the fear of back injury from handling a saddle mic that might weigh up to fifty pounds. The light weight also eliminates the need for a crane to maneuver the instrument, and reduces the operator transit time in moving from place to place.
  4. Saves Operator Time                                                         One of the most noteworthy advances in the Epac 3000 technology is the ability to simultaneously measure roll profile, diameter, and temperature giving the operator and, if requested, a supervisor a colored printout of all three functions on the same page.
  5. User Friendly                                                                         The operator functions are software controlled to provide the most extensive array of pertinent data available quickly, simply, and easily.
  6. Ruggedness                                                                          You can rely on Epac's accurate and reliable performance day in and day out. Epac was designed by a team of world-class engineers to give accurate, reliable measurements in real world roll shops.
  7. It Measures Diameter                                                        The Epac 3000 measures in the same accuracy and reliability range of most C mic operators and better than most Pi tape measurements. Operator training and attitude affect Epac 3000 proficiency to a lesser degree than they do C mic proficiency. With a minimum of training and with a less than stellar attitude, operators can get more accurate and reliable readings with Epac 3000 than with C mics.
  8. Save Time and Money on Repairs                                  Calipers are by design mechanically complicated and fragile. Epac 3000's new patented design is proving to be much more durable than calipers, needing fewer, and significantly less expensive repairs.
  9. Cost-effective Solution                                                  With the advent of the Epac 3000, users are replacing calipers as a more reliable, cost-effective solution to their roll inspections needs.
  10. Flexibility of Use                                                                   Functional flexibility has traditionally been one of the strengths of the saddle-type micrometer. Saddle-mics, unlike calipers mounted on grinders, can be used to skate rolls on a truck, on the floor, and can be moved from shop to shop. Epac 3000 technology takes this flexibility to an entirely new level, providing the following abilities:
  • Spot problems in the mill with the ability to skate rolls all over the plant and to test for temperature as well as profiling problems.
  • With Epac's light weight compact design, troubleshoot problems by skating rolls in any position or location that is physically safe for the technician.
  • By monitoring rolls progressively as they come out of a mill or stand, you can actually monitor mill performance.
  • Skate top and bottom work rolls as soon as they are pulled from a stand (before the set is disassembled) to check for hot spots and profile anomalies.
  • Analyze dirty skates to see if there are problems in the mill that should be corrected.
  • Inspect rolls in the field to spot and identify problems with mills.
