The SICAR META 3 calibrator sander , a used three-phase machine from 1989, is an excellent choice for those looking for reliable and well-preserved second-hand equipment. This sander is particularly suitable for woodworking, and is a robust machine, not CE compliant, which can be easily adapted to current regulations with the installation of additional safety devices.

Visually, the SICAR META 3 looks like a compact but solid machine, with a weight of approximately 2500 kg. It has a footprint of 2000x1600x2500 mm in height, which makes it easy to place in the workshop, but with an important presence. Its belt has a width of 950 mm , allowing it to process large panels, with a vacuum table connected to a 2.2 kW (3 HP) . The belt advancement motor is 0.75 kW and has a speed variator that allows the advancement to be adjusted precisely.

One of the strong points of this machine is the three roller system with different hardnesses (90-50-25 shore) and a diameter of 150 mm , driven by powerful motors, with the first and second roller equipped with 11 kW motors (15 HP) and the third 3 kW (4 HP) . This allows you to perform sanding operations on pieces of different characteristics, from the softest to the hardest.

The SICAR META 3 has an adjustable working height from 3 to 160 mm , perfect for working on a wide range of panel thicknesses. It also has a belt centering system, blowers for cleaning them and pressure rollers, ensuring smooth and constant operation. The sanding belts have a size of 1500x960 mm , which means you can work on large surfaces without having to change the belts often.

For optimal use, it is important to carry out regular maintenance of the machine, which includes cleaning the belts and rollers, lubricating the moving parts and periodically checking the suction system. The mathematical formulas to keep in mind for optimal use concern the advancement speed of the belt and the motor power based on the type of material to be processed. For example, for harder materials, you will need to reduce the feed speed and increase the sanding pressure to ensure an even finish.

Regarding safety, although the machine does not comply with CE regulations, it is possible to adapt it by adding physical protections, emergency sensors and automatic stop systems to guarantee a safe working environment.

This machine is widely used in the woodworking sector, in particular for carpentry shops that require precise and fast sanding on panels of various sizes and thicknesses. The purchase of this used machine represents an excellent deal, especially considering the robustness and reliability of the SICAR META 3, which even after many years of use is able to offer excellent performance at a significantly lower cost than a new machine
