Granite parallel gauges can replace equal height blocks for measuring the parallelism of parts; supplied in pairs. The rock has been subjected to long-term aging, resulting in a uniform tissue structure, a small expansion coefficient, the elimination of internal stress, and no deformation, hence high precision.
Granite parallel gauges can replace equal height blocks for measuring the parallelism of parts; supplied in pairs. The rock has been aged for a long time, resulting in a uniform tissue structure, low expansion coefficient, dissipated internal stress, and no deformation, thus ensuring high precision.
Gabbro parallel gauges are used for measuring the straightness and flatness of workpieces as well as equipment installation. The material for the gabbro parallel gauge is gabbro, primarily composed of amphibole, plagioclase, a small amount of olivine, biotite, and trace amounts of magnetite. It features a black color, a fine structure, and has been aged for billions of years, resulting in uniform texture, good stability, high strength, and hardness. It can maintain high precision under heavy loads and has the advantages of being rustproof, wear-resistant, non-magnetizable, and non-deformable, making it suitable for industrial production and laboratory measurement work.
Advantages of Granite Parallel Gauges:
Rigid, high hardness, and excellent wear resistance.
2. Resistant to acidic and alkaline substances erosion, non-corrosive, no need for oiling, dust-resistant, low maintenance, easy to maintain, and long lifespan.
3. Non-magnetic, smooth movement during measurement without sticking, unaffected by humidity, and excellent flatness stability.
4. No scratches will occur, unaffected by constant temperature conditions, maintaining measurement accuracy at room temperature.
Granite parallels are brittle and susceptible to impacts from hard objects, so they should be handled gently during measurements or use. Care should be taken to avoid impacts from heavy items like metal tools on the surface, to prevent excessive dents that can affect both functionality and appearance.
In case of long-term non-use, wipe the parallel gauge with a special lubricant. If special lubricant is not available, edible oil can be used as an alternative. After reusing, simply dry it with a soft cloth. When the surface is stained, it is advisable to clean the stains with a mild corrosive agent like lemon juice or vinegar. Avoid using soap or baking soda, as these can damage the marble's texture.
