Arriving at “L” very quickly with the “O/V Cut” from Marmo Meccanica

The 45° cut – or “miter cut” – is certainly the most commonly used method to create L-shaped edges for kitchen countertops. A 45° cut is made on the edge of the countertop, the same operation is performed on the edge, the two parts are glued together, and finally, the front side of the edge is polished and beveled.

However, there are two main disadvantages to this type of operation.

The first is that, no matter how well the two parts are glued, the glue line will always be visible at the center of the upper bevel (the most visible one).

The second, certainly worse for manufacturers, is that the 45° cutting operation must be performed on both parts to achieve the joint. This means that for every edge to be worked on, it will require double the length, thus taking double the time.

Marmo Meccanica has implemented a solution that avoids both of these issues, applicable to quartz-resin and ceramics.

It involves a double cut, performed in a single pass, first by the incoming motor (which is usually used to calibrate the thickness of the slab) and then by the outgoing one (usually for performing the drip cut). The result is a profile with a thin “lip”, which can be glued perpendicularly to its counterpart (kitchen countertop or whatever it may be). The scrap piece from this process, which is square in section, can also be used as a reinforcement rib if glued behind the edge created. This way, we have a stable L joint that will allow for a bevel that will be much less visible compared to those made on 45° joints and in a single pass, with speeds of up to 60 m/h.
