Item # A6100, A6100 Series - Aluminum Parallel Straight Edges
List Price $1,745.00


BUSCH PRECISION Aluminum Straight Edges are made to the same tolerances as Cast Iron Straight Edges (in five additional sizes). Starting with a cast aluminum alloy body, this series is specially treated for stress-relief and stability. After pre-machining, the top and bottom faces are fitted with cast iron wear plates which are then bonded to the aluminum body with super strong space-age adhesive. At less than half the weight of cast iron, these aluminum straight edges combine light weight convenience with the wear qualities of cast iron. Available in 10 sizes with precision ground or hand scraped finishes with faces parallel and straight within the tolerances indicated.

BUSCH PRECISION Aluminum Straight Edges provide the upmost in accuracy and convenience. For storage and transport, specially fitted, cushioned cases are available at an additional cost.

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.
