How To Cut Spiral Stairs by CNC Stone Bridge Saw?

Spiral staircases are a timeless architectural element, highly prized in countries like Italy, France, Spain, and the United States for their elegant, space-saving design and striking aesthetics. These staircases combine beauty and functionality, making them popular in luxury homes, hotels, and historic buildings. They are typically made from high-end materials such as marble, granite, engineered stone, and even precious woods and metals, demanding extremely high manufacturing precision-something difficult to achieve through traditional handcrafting methods.

Manual Cutting spiral staircases is a lengthy, labor-intensive, and error-prone process. From marking and cutting to milling and installation, every step relies heavily on the expertise of skilled craftsmen, leading to long lead times, material waste, and inconsistent results. This inefficiency often results in higher costs and smaller project sizes.

CNC bridge Saw machines are designed specifically for handling the complex geometry of spiral staircases, offering unparalleled precision and efficiency. Features below enables automatic and high-efficient Spiral Staircases cutting. 

Cutting Steps:

1. Import .dxf file from CAD to the machine computer

2. Click "Camera" icon tcatch the image of the worktable and the slab

3. Move design photo on suitable possition on the slab to utilize material use.

4. Generate Cuttng paths&Steps with one click on the correspondent icon

5. Start fully automatic cutting

6. Further Finishing

Why Choose these models to produce Spiral Stairs?

1. Electric Spindle for Milling: CNC bridge Saw machines are equipped with an electric spindle for precision milling smooth curves and accurate angles at every step.

2. Rotary Cylinder Assembly for Clamping: The rotary cylinder assembly firmly clamps the workpiece during milling, preventing any movement and ensuring consistent cutting accuracy even for small pieces of slabs.

3. Industrial Computer: Equipped with an industrial computer, the machine can directly receive .dxf files from CAD software or laser measuring instruments as templates. This allows digital designs to be seamlessly translated into actual cutting.

4. High-Definition Camera and Photo Layout Function: An integrated high-definition camera captures image of the slab, while the photo layout function helps operators visualize and optimize cutting plans, reducing waste and improving material utilization.

Our CNC bridge cutters are versatile and capable of handling a wide range of cutting tasks, including:

Kitchen countertops and sinks

Intricately patterned floor and wall tiles

Architectural cladding and facade components

Custom tables, chairs, and decorative items

Precision components for interior and exterior design projects

Thanks to CNC technology, operators can achieve faster production speeds, higher repeatability, and minimal material waste, revolutionizing the way spiral staircases and other complex stone components are constructed.
