Marmo Machinery USA has announced the availability of the CNC waterjet machine, which is capable of cutting complex granite and marble countertops in a single pass.

The CNC waterjet cuts at a rate of 11.8 inches per minute on marble and granite with thicknesses up to 4.7 inches. These cuts are made by high-pressure water mixed with garnet, requiring no tools to change or stock. Electronic metering provides the correct mixture of abrasive and water for optimum machine cutting performance, reports the company.

Cuts require approximately 1 gallon per minute of recycled water, are more accurate than bridge saws and do not use diamond tooling, according to Marmo Machinery. The waterjet can cut complex interior pockets that bridge saws cannot touch, and all tool movements are precisely controlled by a user-friendly CNC.

In addition, the machine has a welded steel frame. It uses a working table dimension of 10.5 x 6.5 feet and handles a load with maximum dimensions of 9.8 x 5.2 feet. Linear guideways provide axis movement and are powered by precision ball bearing screws.

Other CNC waterjet specifications include a weight of 6,834 pounds, 50 hp pump motor and 220/380 V 50/60 HZ electrical power requirements.

Thibaut completely re-designed the T 108 V4 range, which now represents the most powerful models in the company's series. The T 108 L is based on 5 m wall element and automatic longitudinal shiftings. The “L” version fully benefits the evolution of the generation V4, according to Thibaut. It features higher working capacities - 3300 x 1300 mm - and automatic longitudinal functions (edge profiling, drilling and sawing). The T 108 L V4 also benefits from an improved housing, which increases protection of a guiding system. According to the company, the T 108 is one of the most worldwide sold multi-purpose stoneworking centers, and it requires only three training days. Thibaut considers the V4 generation one step beyond the previous version.
