Introduction
1. Standard Overview
This standard GB/T 6202-2019 "Wide Belt Sanding Machine" is a national standard of the People's Republic of China, which is used to regulate the main parameters, technical requirements, inspection rules and safety protection measures of wide belt sanding machines. This standard replaces the old version of the standard GB/T 6202-2000, and updates and expands many technical details.
2. Background of Standard Formulation and Technological Evolution
With the development of the woodworking industry, sanding machines are increasingly used in the fields of processing solid wood boards, artificial boards and metal sheets. The revision of this standard aims to adapt to the needs of modern industry, improve the safety, efficiency and precision of equipment, and conform to the trend of international standardization.
3. Wide-band sanding machine application scope
| Product type | Processing materials | Typical application scenarios |
|---|---|---|
| Single-sided sanding machine (bench type) | Solid wood board, artificial board | Small and medium-sized processing plants, mainly used for single-sided grinding. |
| Single-sided sanding machine (support roller type) | Metal board, inorganic board | High-precision processing requirements, suitable for complex working conditions. |
| Double-sided sanding machine | Solid wood board, non-metallic composite materials | Mass production, realizing double-sided grinding at the same time. |
4. Comparative analysis of standard frameworks
4.1 Comparison of major changes
Compared with GB/T 6202-2000, the main revisions of this standard are as follows:
- Expanded the main parameter series (see Table 1)
- Added safety protection requirements for wet grinding
- Optimized the noise and vibration limits in the idling test
- Supplemented the specific requirements for marking, packaging and storage
5. Safety requirements and protective measures
| Safety items | Specific requirements |
|---|---|
| Protection of exposed rotating parts | Isolation devices must be set to ensure the safety of operators. |
| Emergency stop button | Equipped at a prominent position on the operating table, and its effectiveness is tested regularly. |
| Abrasive belt break protection | A safety device that immediately stops the main motor and feed motor. |
6. Geometric accuracy and working accuracy requirements
The geometric accuracy of the sanding machine directly affects the processing quality. According to Table 3 and Table 4, the equipment must meet the following requirements in the idle running test and load test:
- The radial runout tolerance of key components such as the contact roller and tension roller shall not exceed 0.08mm
- The flatness of the worktable shall meet the IT8 standard
- The uniformity of the sanding surface shall meet the requirement of Ra 0.8 μm
7. Implementation Suggestions and Precautions
To ensure the effective implementation of the standard, it is recommended to take the following measures:
- Strictly select and accept equipment according to the standard requirements
- Regularly check the effectiveness of safety protection devices
- Establish a complete equipment maintenance file
- Operators must undergo professional training and be familiar with the safe operating procedures of sanding machines
