Straight Edge (Wide Type)

 
Model: STRAIGHT EDGE (WIDE TYPE)

Stock No: 205

Product Description: 
  •  
    • The Width is widened so that Levels etc can be placed on it for use.
    • As a standard straight Edge it is suitable for measurement of Parallelism and straightness
    • Use as standard or for inspection of machine running condition, Precision machinery assembly, fixing of turbines for generating plants, etc.
    • Straightness and Parallellism (Not same as JIS height) clears the requirements for Straight Edge JIS Standard (JISB7514 )
    • There are hardened and non hardened types.

 

  • ※・According to the requirement, we can also manufacture special Grade products

  •  ・The box enclosure is a robust type used also for transportation

NOTE

   Bezel Point
 
※・Straightness Measurement

 For our products, the minimun deflection point (bessel point ) is specied by the Straight Edge, and Straightness Measurement is performed. The distance from both edges to the support position P :


P=0.2203×L (L=Lenght Lenght  mm)
