Embodiment 1
[0034] Embodiment 1 discloses a processing technology and equipment for a ceramic gauge block whose size is 1 mm × 30 mm × 9 mm. The measured thickness of the ceramic gauge block is 1 mm, and the process is as follows:
[0035] 1. Since the ceramic gauge block is thin, the effect of bonding stress is greater, and it is easy to produce serious deformation. Therefore, when processing the first working surface (30mm×9mm surface), its thickness can be enlarged from the original 1mm to 2mm.
[0036] Take a ceramic gauge block blank with a size slightly larger than 2mm×30mm×9mm and grind it on a surface grinder using a metal bonded diamond grinding wheel, the diamond particle size is 180#, and the concentration is 100%.
[0037] 2. Then take the larger surface of the ceramic gauge block blank, that is, the surface of 30mm×9mm as the reference surface, and use silicon carbide, diamond and other abrasives to level the two sides of 30mm×9mm on the single-axis lens grinder. The spindle ...

Abstract
The invention relates to a processing technology and equipment for a ceramic gauge block. The process includes: a) preparation of a ceramic gauge block blank; b) grinding the two surfaces with the larger surface of the ceramic gauge block blank as a reference plane; c) Using the above reference plane as the bonding surface, glue multiple blanks into a long strip and grind the four sides; d) pour each edge of the ceramic gauge block to 0.3mm or round; e) process on the plate again Two working faces; f) repairing two working faces by hand, it is characterized in that, the abrasive material adopted in the grinding process of the ceramic gauge block includes materials such as silicon carbide, diamond micropowder, white corundum micropowder, ruby micropowder, and the grain size of abrasive material is at 90 μ Between -0.2μ, the abrasive is mixed into the emulsified solution prepared by distilled water, glycerin or filtered soap solution in a certain proportion to make grinding fluid. The invention also provides ceramic gauge block processing equipment.
Description
technical field [0001] The invention relates to a processing technique and equipment for a ceramic gauge block. Background technique [0002] With the development of modern measurement technology, the requirements for measurement accuracy in some special environments and conditions are higher than before, especially the arrival of the era of nanotechnology, which limits the application of ordinary steel masses, so a A gauge block made of a material with better properties than steel. Based on this, two gauge blocks made of materials with different usage characteristics came into being. One of them is a gauge block made of cemented carbide (that is, tungsten carbide), which has a higher hardness. The other is ceramics (now mainly zirconia (ZrO 2 )) made of gauge block, which has high hardness, corrosion resistance, and non-magnetic. For the former, cemented carbide gauge block, it can basically be manufactured with the same equipment and methods...
