Roughness Comparator Set, Ra Value Sample Blocks Kit, 30 Pieces for Turning Milling Grinding Polishing, SAE Compliant Inspection Gages for Metalworking

Specifications:The exterior roughness comparator is used to check the smoothness of mechanical workpieces by comparison, while the visual inspection or microscope is used to compare and test the degree of exterior roughness.features:RUG-100: notebook sample block (turning, end milling, flat milling, exterior grinding, external grinding, polishing)The notebook sample block contains standards for the six most important processing for methods among the popular "AA" values. All 30 samples were calibrated with for uAA (arithmetic mean) and metric equivalent um Ra.Sample exterior roughness comparator 30 pieces of composite bag fixing gauges3 Flat grinding: 2,4,8; 7/8 "x 3/8" each; Each type of exterior finish is a true and consistent reproduction, with a true idea of the feel, appearance and texture of machined partsCompare conveniently and quickly; Comply with S.A.E and specificationsOverall wallet size (fully enclosed) L x W x H (inches): 6 x 3 x 3/8 * estimated *; Unit weight: 14 ounces * estimate only*The package includes:A set of 30 sample pieces

• [ COMPARISON] Use as a portable roughness comparator to visually and tactilely compare machined parts against standard Ra samples; speeds inspection, process setup and troubleshooting while keeping Ra values at hand.
• [TRUE REPRODUCTION OF FINISH] Each sample is a consistent reproduction of feel, appearance and texture of machined parts; calibrated to Ra arithmetic mean and metric um values and produced to meet S.A.E. specifications.
• [COMPACT WALLET FORMAT] Compact wallet-style holder measures about 6 x 3 x 3/8 inches and weighs approximately 14 ounces, keeping all roughness blocks organized and protected for bench, toolbox or field use.
• [WHO BENEFITS] Suited for machinists, inspectors, toolroom technicians, trainers and buyers who need a portable roughness comparator and Ra reference for inspection, training and process control.
