Automatic CNC Bridge Saw Machine Line

Stone fabrication is becoming more demanding as manufacturers handle larger slabs, tighter dimensions and a wider variety of finished products. A machine used for this kind of work needs to do more than make a straight cut. It must provide enough working range for large slabs, stable movement during heavy cutting and the flexibility to handle different cutting angles.

The Huayi HKNC-500L is developed for this type of production environment. It combines a 5-axis CNC cutting head with an automated slab transfer system, allowing cutting operations and material movement to be arranged within the same production setup. The machine can be used for granite, marble, quartz and other stone materials commonly processed in professional fabrication workshops.

Rather than focusing on a single cutting operation, the HKNC-500L is designed around the complete handling process of a large stone slab-from positioning the material to completing the programmed cuts and transferring the processed pieces.

The cutting head of the HKNC-500L is controlled through multiple CNC axes, giving the operator greater freedom when preparing different cutting patterns.

The A-axis provides 0–90° rotation, while the C-axis can rotate ±185°. This configuration allows the blade to approach the material from different orientations and supports applications such as mitre cutting, angled processing and other multi-directional operations.

The working travel is also suitable for large-format slab fabrication:

X-axis: 3500 mm

Y-axis: 2500 mm

Z-axis: 300 mm

With this working envelope, the machine can accommodate a broad range of countertop, vanity, flooring and architectural stone components without requiring a separate cutting setup for every basic operation.

The HKNC-500L uses an Italian ESA CNC control system, providing a familiar control platform for automated stone processing.

Instead of manually guiding the cutting head throughout the operation, the operator can prepare the required cutting program and allow the machine to carry out the programmed movements. This is particularly useful when the same dimensions need to be reproduced across multiple orders.

The CNC configuration also makes it easier to manage different cutting directions and angles within a single job. For stone manufacturers producing repeated countertop shapes or project-based components, this can help make daily production more consistent.

The HKNC-500L accepts saw blades in the range of Ø350–Ø550 mm. Its main motor is rated at 18.8 kW, providing the cutting power required for demanding stone applications.

The maximum cutting thickness reaches 145 mm, while the maximum lifting stroke is 250 mm. The blade rotation speed can reach up to 6000 rpm, depending on the operating conditions and cutting requirements.

These specifications give the machine enough capacity for common slab-processing work, including:

Granite kitchen countertops

Marble vanity tops

Quartz worktops

Large-format stone panels

Stair and flooring components

Architectural stone pieces

Custom-sized stone parts

The actual cutting performance will naturally depend on the stone type, blade specification, material thickness and selected cutting parameters.

Handling a large stone slab is often just as important as cutting it accurately. The HKNC-500L therefore incorporates a conveyor-based transfer arrangement rather than treating the cutting machine as an isolated unit.

The conveyor has a working width of 2200 mm, providing a suitable surface for moving large-format slabs through the processing area. The loading system has a size of 3076 × 3000 mm, while the suction-cup system has a maximum lifting capacity of 200 kg.

This arrangement helps reduce repeated manual repositioning of heavy stone pieces. Material can be transferred according to the production sequence, while the CNC cutting section concentrates on the programmed machining task.

For factories processing a substantial number of slabs, this type of material-handling design can make the workshop layout easier to organize and reduce unnecessary movement around the cutting area.

Stone cutting generates heat and slurry, making water management an important part of the working process. The HKNC-500L has a stated water consumption of approximately 4 m³/h.

Water is supplied during cutting to support blade cooling and help control the material produced during machining. After cutting, the automated transfer process can also be incorporated into the subsequent handling stage, depending on the customer's production configuration.

This is particularly useful for fabrication facilities where finished pieces need to be moved away from the cutting zone before the next slab enters the workflow.

Suitable for Different Production Requirements

The HKNC-500L can be applied to both standard and customized stone fabrication.

For countertop manufacturers, the machine can be used to produce sink openings, straight sections, mitre cuts and other programmed profiles. In architectural stone production, its larger working range is useful for processing panels and components with specific dimensions.

For marble and granite workshops, the combination of high motor power and 5-axis movement provides greater flexibility than a basic straight-cut bridge saw.

The machine can also be integrated into a larger workshop according to the customer's material-flow requirements. The final configuration can be planned around slab size, production volume, available workshop space and the type of products being manufactured.

The value of the HKNC-500L is not limited to its cutting head. Its design brings together a large working area, multi-axis movement, CNC control and automated slab transportation.

For a workshop, this means that several aspects of the cutting process can be considered as one system instead of purchasing separate equipment for every stage. The 3500 mm X-axis travel and 2500 mm Y-axis travel provide room for large-format work, while the 0–90° A-axis and ±185° C-axis give the cutting head the flexibility required for angled applications.

At the same time, the conveyor and loading equipment address the material-handling side of slab production. This combination makes the Automatic CNC Bridge Saw Machine Line a suitable option for manufacturers seeking a more organized approach to large-scale stone cutting.

The HKNC-500L can be used in a variety of stone-processing applications, including:

Kitchen and Bathroom Fabrication
Processing granite, marble and quartz worktops, vanity tops and related components.

Architectural Stone
Producing panels, flooring elements, stairs and custom building components.

Customized Stone Products
Handling repeated dimensions as well as programmed shapes and angled cuts.

High-Volume Slab Processing
Suitable for factories that need to process large numbers of slabs while maintaining consistent machine movements.

Automation in stone fabrication is not simply about adding more functions to a machine. The more important question is whether cutting, positioning and material transfer can work together without creating unnecessary handling steps.

The Huayi or, 350–550 mm blade range, 145 mm cutting capacity, 3500 × 2500 mm X-Y travel and ±185° C-axis rotation give it the technical range required for demanding slab applications.

For manufacturers looking to improve their stone-processing setup, the Automatic CNC Bridge Saw Machine Line offers a practical combination of cutting flexibility and automated material handling in one machine configuration.

The Huayi HKNC-500L is designed for stone manufacturers who need reliable CNC cutting together with a more structured method of slab handling. Its 5-axis configuration supports straight and angled cutting, while the large working range makes it suitable for oversized stone slabs and production components.

With Italian ESA CNC control, an 18.8 kW main motor, Ø350–Ø550 mm blade compatibility, 145 mm maximum cutting thickness and a 2200 mm conveyor width, the HKNC-500L provides a strong foundation for automated marble, granite and quartz processing.

For factories producing countertops, architectural stone and other large-format components, it can serve as a central cutting solution within a modern stone fabrication workshop.
