HKNC-400PLUS 4-Axis CNC Bridge Saw for Marble, Granite and Quartz Processing

For stone fabrication workshops, a reliable cutting machine needs to do more than produce straight cuts. It should also handle angled edges, shaped components and detailed countertop work without making daily operation unnecessarily complicated. Huayi Machinery's HKNC-400PLUS is designed with these practical requirements in mind.

This 4 AXIS cnc bridge saw cutting machine combines CNC-controlled cutting with versatile stone shaping capabilities. Equipped with an Italian ESA CNC control system, digital servo motors and CAD/CAM drawing software, it helps operators complete different machining tasks with consistent control and less reliance on manual positioning.

The machine is suitable for processing natural stone, engineered stone and ceramic slabs. It can be used in the production of kitchen countertops, vanity tops, stair treads, window sills, wall panels and other architectural stone products.

1. Italian ESA CNC Control System

The HKNC-400PLUS uses an Italian ESA CNC system to manage machine movements and cutting operations. Its 19-inch color touchscreen provides an accessible interface for setting parameters and running machining programs.

With compatible CAD/CAM software, operators can prepare cutting designs and transfer the required machining information to the machine. This is particularly useful for workshops handling different countertop dimensions, custom shapes and repeat orders.

2. Flexible Blade Movement for Different Cutting Angles

The saw head can rotate from 0° to 360° and tilt up to 90°, allowing the machine to perform cutting and edge preparation in different directions.

Depending on the workpiece and programmed operation, it can handle vertical, inclined and horizontal cuts, as well as contour cutting. These capabilities make it useful for producing mitred edges, shaped panels and customized stone components.

Instead of moving between several machines for every operation, fabricators can complete a wider range of cutting tasks on one CNC platform.

3. More Than Standard Slab Cutting

The HKNC-400PLUS is designed for more than basic slab sizing. With suitable tooling and the appropriate configuration, it can also perform drilling, milling, sink cut-outs, profiling and engraving.

An optional electric spindle expands its machining capabilities for applications that require detailed shaping or decorative work. This gives workshops additional flexibility when processing kitchen and bathroom countertops or manufacturing custom stone products.

4. Practical Design for Workshop Installation

The machine adopts a monoblock structure designed to simplify transportation, loading and installation. Its integrated construction is especially practical for workshops that need to consider factory space, equipment delivery and installation arrangements.

The working platform can tilt up to 85° to assist with slab loading. Manual cutting functions are also available for straightforward machining tasks, while manual and automatic nesting options help operators plan cutting layouts and make better use of available slab material.

Optional equipment, including a vacuum manipulator, slab photography system, vein-matching function, slab-thickness probe and tool-measuring system, can be considered according to the workshop's production requirements.

Specifications are based on published HKNC-400PLUS product information. Please confirm the final configuration, electrical requirements and technical details with Huayi Machinery before placing an order.

The HKNC-400PLUS can support a variety of fabrication tasks in commercial and custom stone workshops.

Kitchen countertops: Cut slabs to size and prepare sink openings, edge profiles and mitred joints.

Bathroom vanity tops: Process marble, granite and engineered stone for customized bathroom installations.

Staircases and window sills: Produce straight cuts, angled edges and components to suit project dimensions.

Architectural panels: Prepare stone pieces for wall decoration, flooring and interior finishing.

Decorative stone products: Use suitable milling and engraving tools for selected patterns and shaped details.

For fabricators who regularly switch between standard orders and customized designs, this combination of cutting and shaping functions can help simplify the production process.

Choosing a CNC bridge saw is not simply a matter of comparing motor power or blade diameter. The more important question is whether the equipment matches the materials, product sizes and machining operations required by your business.

The HKNC-400PLUS offers a practical balance of CNC control, flexible blade movement and optional shaping functions. Its 3500 × 2100 mm working platform accommodates a range of slab-processing jobs, while its 22 kW total installed power provides a clear reference for workshop planning.

For businesses looking for a 4 AXIS cnc bridge saw cutting machine that can handle everyday slab cutting alongside selected shaping and engraving operations, the HKNC-400PLUS is worth considering.

Huayi Machinery can help customers evaluate the appropriate machine configuration based on their materials, finished products and production workflow. Optional accessories and software arrangements can be discussed before purchase to ensure the equipment suits the intended application.

Q1: What materials can the HKNC-400PLUS process?

It is designed for natural stone, engineered stone and ceramic materials. The suitable blade, tooling and cutting parameters depend on the material and its thickness.

Q2: Can the machine perform 45-degree mitre cutting?

Yes. Its tilting saw head supports angled cutting, including mitre processing. The appropriate cutting angle and workpiece dimensions should be confirmed against the required configuration and operating conditions.

Q3: Can it process kitchen sink openings?

Yes. Sink cut-outs and related profiling operations are among its intended applications. Suitable tooling and the relevant machining program are required, and an optional electric spindle can extend its shaping capabilities.

Q4: Does the machine support CAD/CAM software?

Yes. The machine is designed to work with CAD/CAM drawing software and uses an Italian ESA CNC control system. Please confirm software compatibility and the included package when ordering.

Q5: Can the HKNC-400PLUS load slabs automatically?

A vacuum manipulator is available as an optional configuration for workpiece handling. The standard machine configuration and the level of loading automation should be confirmed with the manufacturer.
