Surface roughness comparator SA6204KIT

Roughness surface comparator – SA6204EDM-SA6204KIT Surface comparators for mechanical processing, useful for corresponding indicative comparison. Code SA6204KIT – Surface comparators’ kit consisting of 30 plates reproducing the most important and widespread mechanical processes, such as: lapping, grinding, drilling, milling and turning, with different roughness between 0,05 and 12,5 μm in Ra. Code SA6204-EDM – Electrical Discharge Machining “EDM” surface comparator (12 areas), complying with VDI 3400 standard (NB Not suitable for roughness tester calibration or verification). Note: Surface comparators can not be certified.
