. Test platform (inspection plate) Application: Suitable for a variety of inspection, precision measurement of the reference plane; mechanical testing benchmarks for machine tools; dimensional accuracy or shape inspection of parts for deviation, and for close crossed, in the machinery manufacturing is not a lack of basic tools. Surface quality inspection test platform: with coloring hair test. 0 1 plate on each side of not less than 25 points in the range of 25 mm square, two less than 20 points, three less than 12 points. Test platform Precision: According to the national standard verification procedures, namely 00,0,1,2,3 grade four level. Test platform Material: high-strength cast iron HT200-300. Face hardness test platform: HB170-240. Surface quality inspection test platform: with coloring hair test. 0 1 plate on each side of not less than 25 points in the range of 25 mm square, two less than 20 points, three less than 12 points. Also known as cast iron plate platform, its classification range. There are test platform, the basic platform, crossed platform, platform assembly, welding platform, scraping platform, T-slot platform, welding platform, round tablet, fitter platform, measuring platform, grinding platform, coordinate platform. Range using cast iron plate is also extremely widespread, is fitter, assembly, machining, etc. indispensable work platform, so in order to extend the use of cast iron plate time please note the following points in the course of their work: a cast iron plate in use the former must be wiped clean with a non-woven fabric. 2 cast iron plates on the work surface of the workpiece is placed must be kept clean and free of iron slag waste and other refuse or welding items. Otherwise it will cause the cast iron plate scratches caused by the use of cast iron plate time is shorter. Weight of the workpiece 3 cast iron plate work surface placed iron plate itself can not exceed the rated load. Otherwise it would cast iron plate structure cause serious damage or deformation, cast iron platform to shorten time, can cause serious unusable. 4 In the course of using cast iron plate Never vigorously beating or collision, otherwise it will lead to iron flat work surface deformation or damage. The use of cast iron plate to shorten the time. 5 Use cast iron plate will wipe clean work surface rust colored acid-free oil or lubricating oil, and placed in a dry place to avoid rusting iron plate due to shortened time. If the cast iron plate damage or deformation occurs due to collision occur, please look for professionals to carry out maintenance or adjustment. Cast iron plate in order to facilitate the extension of time. Base plate, the basic platform, base plate manufacturers - base plate - the first industry Tools Co., Ltd.
