I. Overview:

" Tolerance fit" display cabinet is an important technical requirement in the design drawings of mechanical parts and an important component of the static and dynamic geometric accuracy of mechanical products. With the development of science and technology and the improvement of production level, higher and higher requirements have been put forward for the geometric accuracy of mechanical products. Geometric accuracy has formed an independent technical discipline and has been favored by knowledgeable people in academia and engineering technology circles. People attach great importance to it.

2. Technical specifications:

1. This display cabinet is composed of six single display cabinets. The overall dimensions of the display cabinet are: 1200×400×1900mm (length×width×height).

2. The cabinet is welded with SPCC cold-rolled plates, and the surface is made of medium-temperature phosphating spray. The cabinet has good rigidity. The display panel inside the cabinet is a super luxurious aluminum-plastic sandwich panel with good load-bearing capacity. The board is equipped with necessary diagrams and text descriptions, and is beautiful in appearance and durable.

3. The back of the cabinet is equipped with double doors, which is convenient for equipment m*ntenance and rep*r.

4. There is a cabinet box at the bottom of the cabinet, which is convenient for storing individual models , experimental boxes and related experimental documents.

5. The bottom of the cabinet is equipped with universal wheels for easy movement and meets ergonomic requirements.

6. The model materials are made of real objects, acrylic organic boards and engineering plastics.
