The contour wire saw in operation. A specific pattern is placed into the machine; individual stones are placed between the idler wheels. The table and saw is hydraulically moved in and out and up and down, which will result in cutting any shape up to 180 degrees in diameter. Shapes include, but are not limited to: S-curves, book tops, concave and convex shapes, etc. This saw is a unique feature of V. Fontana & Co.
