BUSCH PRECISION Dovetails Straight Edges are widely used for checking the alignment and scraping in the dovetail surfaces of machine tool ways and slides. Made from specially treated, close-grained castings, these tools are finish machined and hand scraped to flatness accuracies of 0.0001 per 12” or better. These “scraping masters” are normally supplied with a standard 45° angle. Other angles can be furnished at a nominal, added charge.

RMS

A roughness height rating. It is the abbreviation for root mean square and is a measure of surface roughness in terms of the arithmetic average of the squares of the variances in a given surface. (Fed. Spec. Mil. Std. 10A)

Straight Edge Accuracy

The overall accuracy of each straight edge is carefully inspected and calibrated to insure it falls within the tolerance specified. In use, straightness is dependent upon proper support points for straight edges 60" and longer. Use of these support points minimizes the deflection due to gravity.

60"	6 - 12"
72"	13 - 20"
96"	20 - 26"
120"	25 - 30"
144"	28 - 35"
168"	34 - 40"

To check the accuracy of a properly supported parallel straight edge, indicate one edge or face in the center; then turn the straight edge over and indicate the opposite edge or face in the same manner. Any gravitational deflection should be identical. By measuring the degree of deflection, proper compensation can be made in any alignment application.

To maintain precision tolerances, straight edges must be handled carefully to avoid shock damage. In storage, they should be stored with full horizontal support. Where possible, they should be hung vertically with proper safeguards.
