Fujian Province Hualong Machinery Co., Ltd. is one of the leading manufacturers and suppliers of stone machine in China. With abundant experience, we warmly welcome you to buy advanced stone machine for sale here from our factory. Quality products and reasonable price are available.
Stone factories receive a wide variety of orders daily, far beyond simply cutting slabs into pieces.
For example, a kitchen countertop might require first cutting the stone, then drilling holes for the sink and faucet, beveling, etc. It might even involve curves or irregular shapes. With high-value materials like marble and luxury stone, the grain arrangement and defects must be considered, preventing arbitrary cutting.
If each process uses different stone machine, the slab would have to be constantly moved around and repositioned-time-consuming and labor-intensive!
The HKNC-500PLUS is specifically designed for these production scenarios.
It is a 5 axis CNC stone processing machine. It features multiple functions including cutting, irregular shaping, drilling, milling, carving, and sink processing.
The machine uses three linear axes (X, Y, Z) and two rotary axes (A, C) for five-axis linkage, capable of processing natural stone, artificial stone, ceramic slabs, and stone blocks.
Therefore, if your stone processing plant has a wide variety of orders and frequently produces customized products, or if you want one machine to handle multiple processing tasks, then we recommend purchasing the HKNC-500PLUS.

What problems can a 5-axis bridge cutting machine solve for stone factories?
The HKNC-500PLUS uses five axes linked together: X, Y, Z, A, and C.
X, Y, and Z control the tool's position movement. A and C control the changing of the processing direction. The machine can process curves, beveling, irregular shapes, and machining in different directions according to the program.
If you are simply cutting straight slabs, the advantages of a 5-axis machine may not be so obvious.
However, if you start machining irregularly shaped surfaces, complex edges, bevels, chamfers, etc., the benefits of a 5-axis machine become more apparent.
The machining head can change the processing direction; the A-axis rotation range is ±90°, and the C-axis supports 360° rotation.
This allows the tool to change direction according to the program during processing to complete beveling, chamfering, curves, and irregular shapes.
Note:360° rotation refers to the C-axis, which is the rotation of the machining head, not the 360° rotation of the worktable.
The worktable itself can tilt up to 85°, mainly for convenient loading and unloading of slabs and operation.


From Drawings to Processing: A Simplified Process
The HKNC-500PLUS doesn't rely on operators manually controlling the machine step by step.
Normally, CAD drawings are created based on the customer's product, and then a machining program is generated using Pegasus CAD/CAM software. The system supports DXF file import, and the program is then sent to the CNC system for execution.
Once the slab is placed, the machine completes the corresponding processing according to the program.
Standard products can be cut directly.
For irregularly shaped products, curved contours can be machined according to the drawings.
If the product requires sinks, faucet holes, drilling, milling, or engraving, it can also be processed according to the corresponding program and tools.
The benefits of this are straightforward:
Changing a product mainly involves changing the drawings and machining program, rather than redesigning an entire machining process.
This is particularly useful for factories with a large number of custom orders.

What processing capabilities can the HKNC-500PLUS perform?

Slab Cutting
It can perform straight cuts, perpendicular cuts, beveling, and cuts in various directions.

Curve and Irregular Shape Cutting
It can process round, elliptical, curved, and other irregular shapes.

Drilling and Milling
By changing the appropriate tools for different products, it can handle drilling, milling, and other processing tasks.

Sink and Hole Processing
It can perform sink openings, faucet holes, and other drilling and milling operations

Beveling and Edge Cutting
By changing the direction of the processing head according to the program, edge processing at different angles can be achieved.

Engraving
With appropriate tools, it can perform stone engraving and curved milling.
What are the applications?
Kitchen Countertops:
Kitchen countertops are rarely just a simple rectangle.
Besides shape cutting, they may require machining of sink holes, faucet holes, chamfering, curves, etc.
These tasks can all be performed using CNC programs.
Bathroom Countertops and Washbasins:
Can be used for machining such as opening holes, irregular contours, curves, and milling.
Marble and Luxury Stone:
For high-value natural stone, pre-processing planning can be done using image acquisition, layout, and texture matching functions.
The focus here is not simply on increasing cutting speed, but on using each slab in the most suitable position.
Decorative Stone:
Projects such as hotels, villas, and commercial spaces. Curved, irregular, or sculpted products.
Custom Processing:
If you are processing products of different sizes and shapes every day, using CNC stone processing equipment will be more convenient.
