Why Choose Us?

Bridge Saws (4-Axis)

‍

The bridge saw is the ideal choice for daily operations in any marble and stone workshop. Our 4-axis range combines maximum structural stability with fast, secure loading and rotation systems, developed to support high production rates without compromise.

The HTO 4, HTO 4JS, and HTO 4 MAXI models offer targeted configurations: from the JS version with an extended X-axis stroke of 3,900 mm for Jumbo Size slabs (3800×2000 mm), to the MAXI version designed to mount blades up to 1,200 mm with a 600 mm vertical Z-axis stroke for processing significant thicknesses.

Equipped with a 24 HP S6 blade motor featuring a standard inverter (960−4,500 RPM), our bridge saws reduce setup times and ensure great operational flexibility, supported by the open Zeus software with a lifetime license.

    Frequently Asked Questions

    Bridge Saw FAQ

    What is the main advantage of the HTO 4JS version compared to the standard HTO 4?

    Plus Icon

    The HTO 4JS version offers an increased X-axis travel of 3,900 mm, specifically designed to process Jumbo Size (3800×2000 mm) quartz and agglomerate slabs without limitations.

    What types of processing is the HTO 4 MAXI milling machine suitable for?

    Plus Icon

    The HTO 4 MAXI is developed for those working with significant thicknesses and massive blocks: it supports blades up to 1,200 mm in diameter and offers a Z-axis vertical travel of 600 mm.

    How is the work table structured on the bridge models?

    Plus Icon

    The HTO 4 and HTO 4JS models come standard with an indexed (0°/45°/90°) tilting table to facilitate slab loading. Automatic rotation managed by the CNC is available as an option.

    Why does the blade motor come with a standard inverter?

    Plus Icon

    The inverter on the 24 HP motor allows for blade speed adjustment from 960 to 4,500 RPM, optimizing the cut based on the tool diameter and material hardness (from soft marble to porcelain or granite).

    What is the added value of the optional automatic rotating head?

    Plus Icon

    The automatic rotating head (0°/90°) allows for fully automatic angular cuts and 45° chamfers, eliminating the need to manually reposition the piece on the table.
