Looking to buy an affordable automatic bridge saw for cutting personalized shapes and contours in quartz, granite, marble, slabs and tiles to create custom kitchen countertops and bathroom vanities? Check out this best 4-axis CNC bridge saw stone cutting machine for sale at cost price in 2025.
Most custom kitchen countertops and vanity countertops are made of marble, granite, quartz, rock slabs, and ceramic tiles because they are corrosion-resistant, pollution-resistant, high-temperature resistant, impact-resistant, waterproof, easy to clean, beautiful, and durable.
Decoration workers usually use portable masonry saws to cut personalized countertops. But the speed is slow with low precision, and the stone dust is easy to cause environmental pollution. Later, some stone workers chose CNC router machines to cut countertops. Although the precision was higher, the speed was too slow, even inferior to handheld masonry saws. In this case, a new type of smart automatic stone-cutting tool came into being. It is the CNC bridge saw, including 2 common types of 4-axis and 5-axis. The following is the 4-axis bridge saw with infrared positioning for automatic stone cutting.
4-axis bridge saw stone cutting machine integrates horizontal cutting, vertical cutting, 45-degree oblique cutting, round, oval, special-shaped layout, infrared positioning, CNC automation, and other functions. It is used to cut quartz, granite, marble, rock slabs, ceramic tile, slate, and other stone materials. It aims to solve the problem of time-consuming, labor-intensive, and high-cost high-end technology in the production process of stone countertops.

I have been in home improvement for almost 10 years and Ive used a variety of handheld masonry saws to cut granite for making personalized kitchen countertops and this thing is great for the simple stuff. I needed an automatic bridge saw to grow my business and this didnt let me down. It can easily cut through the natural slab granite, like a hot knife through butter. Great CNC stone cutting machine. Well worth the money saved in time alone.
