Surface Roughness Comparator Standards Composite Set
Surface roughness comparison sample block is a kind of working measuring tool which is used to check the surface roughness after machining. By visual inspection or magnifying glass and the measured workpiece surface roughness comparison, judgment level.
· Materials and specifications:
Material: in addition to the grinding sample blockGCr15The rest of the material is used.45Made of high quality carbon structural steel.
Specifications: a total of three kinds
· Seven sets of samples (lathes, Chuang Chuang, vertical milling, milling, flat grinding, grinding, grinding)
· Six sets of samples (lathes, Chuang Chuang, vertical milling, milling, flat grinding, external grinding)
· Single set of forms: (lathe sample block, create bed type block, vertical milling sample block, flat milling sample block, flat grinding sample block, external grinding sample block, grinding sample block)
· Classification and roughness parameters such as table:
| manufacturing method | Lathe | A bed | Vertical milling | Flat milling | Flat grinding | External grinding | Grind |

· Use maintenance notes:
Comparing samples should be used and the detected parts in the same conditions (including surface color, lighting conditions, etc.) shall not be in direct contact with the comparison Sppecimens strict antirust processing by hand, to prevent rust, and avoid scratches.
