  • Quality inspection and alignment tooling
  • Precision ground steel edges
  • We build straight edges up to 16 feet long
  • Specials and custom designs available

 
                 
  We supply precision straight edges from 3 feet to 16 feet long for inspection and alignment applications. These value priced standard straight edges are made from steel and are precision ground. Our standard precison straight edges include ONE useable edge. The flatness and straightness specifications for steel straight edges range between 0.001 to 0.004 inch depending on the length of the unit. The tolerances for the maximum allowable deviation over the length of the entire measuring surface are shown in the chart below:

  Straight Edges with Certified Quality  
  Have you ever noticed how most of our competitors never mention what sort of quality they provide with their straight edges? We provide certification document for each precision straight edge. We will check your precision straight edge using a certified granite surface plate with traceability to NIST standards. Our inspection procedures check the flatness and straightness for each straight edge.

Standard straight edges include certification for only ONE edge. We cannot guarantee the quality of both edges of the straight edge unless we grind and certify both sides.
We can certify both edges for an additional charge of $125. In addition to the extra grinding and inspection time, this additional charge includes masking, cleaning tape residue, and applying rust preventative on the two unpainted edges. If you purchase this extra option the straight edge will include TWO useable edges that are straight, flat, and parallel within the tolerance specified. We can also inspect and re-certify one edge on most straight straight edges up to 12-foot long for only $125.

Sample Inspection Certificate

           
  Straight Edges Made from Durable Steel        
  Our standard precision straight edges except our PaveFlat Runway Units are built from hot rolled steel that has not been heat treated. Hot rolled steel does not require annealing and the high temperature prevents stress from accumulating in the material which results in better dimensional stability than cold worked materials. Our units typically hold shape better as there is no residual memory effect from stresses caused by hardening. We achieve very close tolerances at competitive pricing. Most of these units were designed for careful inspection and used by professionals who know how to handle a precision tool. Unfortunately, even hardened steel will nick if dropped.
                 
  Corrosion Protection Included on Straight Edges        
  Standard precision straight edges are normally painted on five sides to prevent corrosion. This leaves only one side to keep oiled. We can leave your unit unpainted but then you would have to oil all of the sides or it would rust. Then it would then be very slippery to pick up. The unpainted side is certified for the entire length of the unit.
                 
  Chamfers on Edges Included on Straight Edges        
  We normally chamfer the four edges on a straight edge to prevent cuts when handling. The standard straight edge includes lightly chamfer edges that measure (45º x .010")

  FAQ and Other Alternatives  
  Frequently asked questions include: Do I really need to lug around a heavy steel straight edge to check flatness and straightness? What about using Lasers? Isn't there something easier or cheaper out there? Why can't we check it with our CMM? Couldn't I just buy some ground flat stock and use it? Will aluminum straight edges work?

Frequently Asked Questions

                 
  Applications for Precision Straight Edges        
  Precision straight edges are useful for leveling machine tools and checking the flatness of surfaces. In most of these applications, the straight edge is used as a reference surface to check your part. With a straight edge you can track and isolate potential sources of error. The amount straightness deviation usually measured by inserting a feeler gauge between the part and the straight edge.   Our customers keep finding new and innovative uses in a wide range of industries. Our precision straight edges are being used for the following applications:
