Detection Platform

The Beizhong manufacturer's production inspection platform serves as a reference plane for precision measurement in production workshops or metrology departments. Manufactured according to the JB/T7974-1999 standard, the product is constructed in a ribbed plate or box-type design, with working surfaces available in rectangular, square, or circular shapes.
Inspection platform alias: Inspection plate
Technical requirements for inspection platforms:
Inspection platform process: The working surface employs a scraping process and can be machined with V-grooves, T-slots, U-slots, dovetail grooves, round holes, long holes, etc.
Inspection platform purpose: Used as a planar reference measuring tool for workpiece inspection or marking.
Quality of inspection platformInspection: The working surface of the inspection plate (inspection platform) should be free from rust marks, scratches, impact damage, and other appearance defects that affect its use.

Precision classification
1. The flatness of the inspection platform can be divided into:
①、AA grade: Its flatness (um) = 1 + 1.6D² (D is the diagonal length or diameter of the platform), used for highly precise measurements, often in laboratories. ②、A grade: Its flatness has twice the error of AA grade, commonly used in tool inspection rooms for precision measuring instrument verification. ③、B grade: Its flatness has four times the error of AA grade, often used in tool inspection rooms or on-site for inspecting measuring tools or marking.
Inspection plate accuracy: Executed according to the national standard metrological verification regulations, divided into four levels: 0, 1, 2, and 3.
Inspection platform specifications: 200mm*200mm---3000mm*6000mm
