Woodworking machines: What work can they do?
May 12, 2021
The Planar Sanding System is an innovative method patented by EMC Italy that enables high sanding standards to be achieved. The system is integrated in the Plano machine, a multi-purpose sander for multi-directional superfinishing.
The expert Stefano Callegaro answers and explains this new sanding system and its advantages.
Why is it called the Planar System?
The contact between the panel and the abrasive belt is made on a perfectly flat surface, so that the The contact between the panel and the abrasive belt takes place on a perfectly flat surface, so that the sanding is planar, i.e. uniform over the entire surface. With this system, once the panel is inserted in the machine, it is as if it were "gliding" over the abrasive rollers. The result is the Plano machine, which was developed to fully incorporate our innovative patented sanding system''.
What's innovative about the Plano machine?
Before the Plano machine, sanding was done using the Longitudinal System, or wide belt machining, and the Transverse System, or narrow belt machining, with the help of electronics of course. The particularity of the Plano lies in the rotary sanding system, which combines 3 different systems in a single movement.wide sanding belt + 2 fixed electronic pads + the rotation of the entire sanding unit''.
What is meant by 4D sanding?
This method is the result of normal sanding systems, on which we intervene by modifying 3 dimensions if necessary: the speed of the belt, the pressure of the pads, and the speed of the sanding belt; the planar method adds a fourth "dimension" that can be modified: the speed of the rotary unit.which determines the sanding effect on the panel. The result is sanding in 4 Dimensions''.
What advantages can a Planar System machine provide?
In addition to high-quality, homogeneous sanding in all areas, there are other advantages:
- Ease of use, as the machine requires no special training thanks to its intuitive control system, which can store more than 200 sanding programs
- Increased Production
- Saving on electricity costs
Optimising the life of the beltsThe belts not only grind evenly when rotating, they also wear evenly, increasing their service life''.
Can the Plano be configured as required?
''Yes, the Plano machine has 4 different configurations:
- Basewhich allows maximum versatility on the product
- StrongSuitable for heavy machining where preliminary roughing is required.
- DelicatePerfect for pre-brush sanding and high quality finishing.
- Customconfiguration mode on demand''.
