Hebei Beizhong Inspection Plate, cast iron inspection plate is suitable for various inspection tasks, serving as a reference plane for precision measurement, a benchmark for machine tool and mechanical inspection measurements, checking the dimensional accuracy or form deviations of parts, and for precise marking. The inspection plate is an indispensable basic tool in mechanical manufacturing.
The flatness of the working surface of the inspection plate and cast iron inspection plate is the primary accuracy indicator for measuring their quality. According to the national standard GB/T22095-2008, which specifies the allowable flatness tolerance for cast iron inspection plates, the accuracy grades are determined as levels 0, 1, 2, and 3. The inspection plates produced by Beizhong Company undergo two rounds of artificial tempering, vibration aging, precision planing by machine tools, manual fine scraping, and strict inspection by national quality inspection departments. The products are rigorously processed through every stage, with meticulous attention to minor differences in each step. Additionally, to prevent the inspection plate from fracturing under heavy loads, Beizhong adopts structures that facilitate free contraction of the plate or strengthens the structural integrity in areas prone to cracking. These comprehensive improvements further enhance the high efficiency of Beizhong's inspection plates, providing a stronger competitive edge in the market.
Uses of Inspection Plate: Suitable for various inspection tasks, serving as a reference plane for precision measurement, a benchmark for machine tool and mechanical inspection measurements, checking the dimensional accuracy or form deviations of parts, and for precise marking. The inspection plate is an indispensable basic tool in mechanical manufacturing.
Inspection Plate Parameters: Materials include HT200-300, QT400-600, ZG15-45, with hardness HB170-240. The working surface employs scraping technology and can be processed with V-grooves, T-grooves, U-grooves, dovetail grooves, round holes, long holes, etc. Inspection Plate Appearance: Designed in T-shape or I-shape, with working surfaces in rectangular, square, or circular forms. It should be marked with the manufacturer's name (or logo), accuracy grade, specifications, and serial number. The working surface should be free from cracks, rust spots, scratches, impacts, dents, impurities, and other defects that could affect the accuracy of the inspection plate.
Maintenance of Inspection Plate: During use, avoid excessive local wear, scratches, and impacts to prevent affecting the accuracy and service life of the working surface. Under normal conditions, the service life of the inspection plate should be permanent. After use, clean it thoroughly and apply anti-rust measures to prevent corrosion and deformation of the working surface.
