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. |

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? For a few ideas concerning possible alternatives to using precision straight edges

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: |
