Quality inspection reports are essential for verifying that the horizontal spindle surface grinder meets industry standards and precision requirements. Key elements of a quality inspection report include:
| Inspection Item | Standard / Specification | Acceptable Tolerance |
|---|---|---|
| Flatness of Table | ISO 230-2 | ≤0.002 mm |
| Spindle Runout | ISO 230-7 | ≤0.001 mm |
| Surface Finish (Ra) | ISO 4287 | 0.2–0.8 µm |
| Table Parallelism | ISO 230-2 | ≤0.002 mm |
| Electrical Safety Check | CE, ISO 12100 | Pass |
| Cooling System Performance | Manufacturer Specification | Optimal flow rate |
These reports provide confidence that the grinder can deliver consistent and repeatable results, which is crucial for high-precision manufacturing environments.
Proper storage and handling ensure that horizontal spindle surface grinders remain in optimal condition before installation or during downtime.
Store in a dry, temperature-controlled environment between 20–25°C.
Maintain relative humidity below 60% to prevent corrosion of metal components.
Avoid direct sunlight or proximity to heat sources.
Place the grinder on a vibration-free, level surface.
Protect electrical panels and control units from dust and moisture.
Use protective covers for the spindle, table, and exposed mechanical components.
Lock all moving parts before transport to prevent damage.
Use proper lifting equipment, such as forklifts or cranes, for heavy models.
Verify calibration and alignment after relocation.
Proper storage and handling reduce the risk of damage during transport and ensure the grinder remains ready for immediate operation.
