Description and Main Components

Visually, the 4RT 300 calibrator sander presents itself as a solid and compact unit, built with resistant materials to support years of industrial use. The body is made of sturdy steel, designed to resist wear and vibration during the sanding process. At the heart of the machine is the high-quality rubber sanding roller

The main components of the model include:

• Calibrating and sanding roller with a standard diameter of approximately 300 mm, designed to process materials of different sizes with extreme precision.
• abrasive belt that allows you to adapt the machine to different types of surfaces to be treated.
• Electric motor with significant power, capable of managing an intensive production cycle without risks of overheating or interruptions.

Technical Data and Mechanical Characteristics

Here are some of the key technical specifications of the 4RT 300 model :

• Year of construction: 2002
• Maximum working width : 300 mm
• Roller diameter : 300 mm
• Motorization : 380 V
• feed speed to adapt to the type of material and desired finish.

The machinery is capable of treating materials such as wood, plastic and metals, thanks to the possibility of modifying the abrasive belts according to needs. This versatility makes the 4RT 300 calibrator sander a suitable solution for a wide range of industrial applications, such as the production of furniture, fixtures or metal components.

Usage Procedure

Using this sander calibrator is simple and intuitive, even for those who do not have much experience with this type of machinery. The workpieces are placed on the conveyor belt, which takes them inside the machine. Once the advancement speed and roller pressure have been set, the machine begins the processing cycle, guaranteeing a homogeneous finish over the entire surface.

The control panel is equipped with simple controls that allow you to precisely adjust the speed and power based on the type of material treated. Furthermore, the presence of safety sensors and automatic blocking devices guarantee safe operation, avoiding accidents during the work phases.

Accessories and Improvements

Among the accessories that can be combined with this machine, we find:

• Abrasive belts of different grits , to adapt the sander to various types of work.
• Suction systems to remove dust and residues resulting from the sanding process, improving both the quality of the work and the safety of the environment.

Formulas and Parameters of Optimal Use

To obtain the best results with the 4RT 300 , it is essential to carefully calibrate the processing parameters. Feed speed ( V) and roller speed (Vr) are among the main factors to monitor. For example, a basic formula to consider might be:

$$\text{Material removal rate (MRR)}$$

Where A is the contact area between the abrasive belt and the workpiece. In general, the higher the feed speed, the faster the sanding process, but care must be taken not to compromise the quality of the finish.

Maintenance and Safety Regulations

Being a used machine, periodic maintenance is essential to prolong its useful life and maintain high performance. Some tips include:

• Regular cleaning of the rollers and sanding belt to avoid accumulations of dust or debris.
• Checking bearings and motors to prevent mechanical failures.
• Periodic replacement of abrasive belts , based on the number of working hours.

Regarding safety regulations , the 4RT 300 model is equipped with integrated safety devices, but it is essential to check that the machine complies with CE . If the certification is missing, the necessary modifications will have to be made to ensure compliance with current regulations, for example by installing additional protections and emergency stop systems.

Sectors of Use

The 4RT 300 calibrator sander is widely used in the carpentry and furniture industry sectors, but is also used in the processing of plastic and metal materials. Thanks to its versatility and robustness, it is perfect for those who need a reliable machine for large-scale work.

Why It's Better to Buy Used

Buying a used machine like the 4RT 300 allows you to obtain professional performance at a reduced price compared to a new machine. Despite the year of construction of 2002, the 4RT 300 model still offers excellent performance today and, with good maintenance, can continue to work for many years. Furthermore, the brand is renowned for the quality of its products, which makes this sander a safe and affordable investment.

Ultimately, if you are looking for a used calibrator sander , the 4RT 300 model from 2002 represents an advantageous deal that combines robustness, versatility and precision, adapting perfectly to the needs of multiple industrial sectors.
