Surface Roughness Comparator Manufacturer,Supplier and Exporter in India
Product Code : EL-TT-13342
DESCRIPTION:
Surface Roughness Comparator
The measurement of Surface roughness Comparator is not as straightforward as most other engineering measurements, such as length or angle or hardness; and in order to get good accuracy, expensive instruments are needed.
These are often unsuitable for workshop use, where roughness of machined surfaces can usually be assessed conveniently and with sufficient reliability using visual and tactile (fingernail) comparison with a standard set of surfaces machined in the same way.
This set consists of 30 comparison specimens, covering six commonly-used machining methods (6 turned, 6 end-milled, 6 horizontally milled, 6 surface-ground, 3 lapped, 3 reamed/drilled.
Applications:
checking roughness of turned, milled, ground, reamed, polished or lapped parts during machining
checking the roughness of spark-eroded surfaces as described in the VDI 3400 Guideline
checking the roughness of steel surfaces which have been prepared for painting by blast-cleaning.
Estimating surface roughness prior to accurate measurement by a stylus instrument.
checking the seriousness of damage to parts caused by nicks, dents and scratches
checking reconditioned ship propeller blades
