About gauge blocks’ history:Gauge blocks were invented in 1896 by the Swedish mechanic Carl Edvard Johansson. They are used as a reference for calibrating measuring devices used in machine shops, such as micrometers, sine bars, calipers and micrometers (when used for inspection). Gauge blocks are the main means of standardising lengths used in industry.Product Details:Material: steel, surface hardened to HRC58-62 °, nickel plated.Dimensions: approx. 75 x 25 x 36MM (L x W x H)Color: as picture showsAngular Precision 10 'On Readable NoniusMicro Adjustable 0 ° To 60 ° With Stop ScrUses: In the milling machine, planer, drill press with adjustable angle grinder and regulations on the , crossed with other fixtures or clamping the workpiece after the workpiece processing, such as processing slope, slant-hole drilling and the like.Nickel plated, rust parallelism and verticality precision grinding of each working face to 0.01mm.It can be a cursor indicates stepless tilt adjustment angle, and then be secured with screws, used to create a variety of fixed angle processing, testing of workpieces.Package included:1 x adjustable angle block1 x wrenchTips when you use them:To use them, the blocks are removed from the set, cleaned of their protective coating (petroleum jelly or oil) and screwed together to form a stack of the desired size. The blocks are calibrated accurately at 20 °C (68 °F) and should be kept at this temperature when measuring. This mitigates the effects of thermal expansion. Wear-resistant blocks, made of a harder substance such as tungsten carbide, are mounted at the ends of the stack wherever possible to protect the gauge block from damage during use.
