747 SERIES ID-OD MEASURING TABLES

The Highest Accuracy and Repeatability

Dyer’s 747 Series is a high-precision measuring table based on a precise linear movement of the moveable contact point. A single unit offers a choice of 2-point measuring or 3-point measuring. The gage can be set up as a “hands off” gage, where the operator places the part on the table and releases the measuring contact. There is no operator error and the system will provide Gage R & R capable measurements. A wide range of gaging options makes this gage Dyer’s most flexible in many measuring applications, such as thin walls, plastics and hard to reach locations on metal parts.

747 Series ID-OD Measuring Tables Design Benefits

1. 1. Gage top plate is hardened and ground tool steel; comes standard with a thin dense chromium (TDC) satin finish coating (RC70-74); and tapped Mb threaded holes for attaching different contact accessories or fixture mountings. Key properties of thin dense chromium (TDC) include low coefficient of friction; greater lubricity and nonballing properties; high chemical and corrosion resistance, high surface hardness (RC70-72); high abrasion resistance and longer wear life. These extra-ordinary properties translate to distinct performance advantages over ordinary steel top plates.
2. 2. Rigid steel base
3. 3. Retracting lever for large range 0.800″ (20 mm)
4. 4. Contact adjustment screws can limit retracting contact point travel
5. 5. Fine adjustment of measuring pressure and direction (ID or OD) is accomplished by rotating springloaded disc located on opposite side of base across from retracting lever #3.
6. 6. Fixed contact point arm adjust easily for different contact point heights.
7. 7. Moveable spring loaded measuring contact point arm adjusts easily for different contact point heights.
8. 8. 3/8″ standard or 8 mm optional collect for holding indicating unit.

These gages are true value leaders and gage most measuring applications.
