Hardware knowledge: the purpose and type of measuring tool flat

The purpose of the measuring tool plate

Plate is a plane reference instrument used for workpiece detection or scribing. This definition indicates the nature, function and purpose of the tablet.

The tablet is an instrument that reproduces the value in a fixed form. It is a physical measuring tool.

The flat working surface is often used as a plane datum, used to calibrate and adjust other measuring instruments or as a standard to compare with the measured part, specially used for form and position error and measurement, so it is a form and position error measuring instrument.

The naming of the plate also points out the specific purpose for workpiece inspection or marking.

Larger size splints are collectively referred to as platforms when they are installed on special brackets.

Types of measuring tools

According to its material, it is divided into steel slab, cast iron slab, rock slab, marble slab and granite slab. According to its structure, cast iron slabs are divided into ribbed plate type and box type, and rock slabs are divided into flange type and non-flange type.

According to its purpose, it can be divided into inspection plates, scribing plates and sand-pressing plates. According to their accuracy levels, they are divided into levels 00, 0, 1, 2, and 3, of which level 2 or higher is for inspection plates, and level 3 is for scribing flat.

This division further guarantees the process performance and internal quality of the high-precision flat panel. The culture plate (cultureplate) is the most commonly used form of solid culture medium used to obtain pure culture of microorganisms. It is the solid surface of the culture medium formed by the solid medium after cooling and solidification in a sterile petri dish. It is often referred to as a flat plate ( plate).
