The lapidello is a machine used for smoothing, polishing and finishing flat or shaped surfaces, typically on hard materials such as metals and stones. It is used above all in mechanical workshops, watchmaking laboratories and in the goldsmith sector, as well as for the preparation of metallographic samples. Buying a used lapidel can be an excellent choice for several reasons. Let's see in detail how it works, how to use it, the types available, the workable materials, the alternatives available, and the advantages of purchasing a used model.

### 1. **How ​​It Works**
The stone grinder works through an abrasive disc that rotates at high speed. The workpiece is pressed against the disc, which removes small amounts of material from the surface, smoothing or polishing it. The disc can be equipped with different types of abrasives depending on the material to be treated and the desired finishing level.

### 2. **How ​​to use it**
- **Preparation**: The workpiece is fixed on a support, often with a special vice, and the appropriate abrasive disc is selected.
- **Processing**: The machine is turned on and the piece is pushed against the rotating disk with uniform pressure.
- **Control**: During processing, the surface is checked to verify the degree of smoothness or polishing achieved.
- **Cleaning**: After use, the machine and the workpiece must be cleaned to remove material and abrasive residues.

### 3. **Types of Stones**
- **Manual Stones**: The operator manually controls the pressure and position of the piece on the disc.
- **Semi-Automatic Stone Stone**: Equipped with mechanisms that assist the operator in moving the piece.
- **Automatic Stone Stone**: Entirely controlled by an automatic system, programmable to perform repetitive jobs with high precision.

### 4. **Workable Materials**
- **Metals**: Steel, copper, aluminium, various alloys.
- **Stones**: Granite, marble, agate, other semi-precious stones.
- **Glass**: For sanding and polishing.
- **Composite Materials**: Such as fiberglass and similar materials.

### 5. **Alternative Machinery**
- **Grinding machine**: Used for finishing flat and cylindrical surfaces, similar to lapidel but with greater precision.
- **Polisher**: Specific for polishing surfaces without removing too much material, more suitable for the final processing phase.
- **Belt Sander**: Suitable for roughing and finishing flat and curved surfaces, particularly useful for less hard materials.

### 6. **Why it is better to buy a used lapidel**
- **Lower cost**: Buying a used lapidel can lead to significant savings compared to a new model, reducing the initial investment.
- **Reliability**: Lapidelli are robust and durable machines; a used model, if well maintained, can provide years of efficient service.
- **Immediate Availability**: A used lapidary machine can be immediately available, without the waiting times necessary for purchasing a new machine.
- **Performance Evaluation**: A used model allows you to observe how it has behaved over time, with any defects already identified and resolved.
- **Wide Choice**: The used market offers a variety of models, from the simplest to the most sophisticated, allowing you to find the machine suited to your needs and budget.

In conclusion, a used lapidel represents an economical and effective solution for those who need a reliable machine for sanding and polishing hard materials, without having to invest a large sum for a new model. However, it is essential to check the condition of the machine before purchasing, to ensure that it is in good operating condition.
