Slab Image Capture (Optional)

The application allows to acquire and process the slab photo, by correcting the lens distortion and rectifying it. Through the
acquired image, the shapes can be arranged on the slab avoiding material imperfections while identifying the nervures that need to
be machined; it is also possible to qualify the slab edge geometrically.

Digital Servomotor

Choosing a good bridge cutter (bridge cutter) requires comprehensive consideration of processing requirements, machine performance, brand service and other factors. The following is a key purchase guide to help you make a wise decision:

1. Clarify processing requirements
Before purchasing a bridge cutter, first clarify your main processing objects and goals:
Material type: marble, granite, quartz stone, ceramic slabs? Different stones have different hardnesses, which affects the machine power and tool selection.
Processing size: maximum cutting length, width, thickness? Do you need an oversized specification (such as more than 3200mm)?
Cutting method: only straight cutting is required, or is bevel cutting, curve cutting, or contour carving required?
Production requirements: small batch customization or large-scale production? Determine the degree of automation required.

2. Core performance parameters
(1) Mechanical structure and rigidity
Bridge type vs gantry type: Bridge type is suitable for large plate cutting, gantry type is more suitable for heavy rough material processing.
Guide type:
Linear guide: high precision, high speed, suitable for fine cutting.
Gear rack: strong load-bearing capacity, suitable for heavy-duty cutting (such as granite).

Material: high-quality cast iron or welded steel structure to ensure long-term stability and reduce vibration.

(2) Cutting capacity
Spindle power:
Marble/ceramic: 15kW is sufficient.
Granite: 15kW or more is required, and hard stone requires higher power.
Cutting speed: high-speed cutting (such as 20-50m/min) can improve efficiency, but accuracy must be taken into account.
Maximum cutting depth: single cutting depth (usually 100-200mm), does it support layered cutting?

(3) CNC system
Brand selection: ESA, Siemens, etc. System stability is crucial.

Function support:
Does it support direct import of CAD/CAM (such as DXF, DWG, NC code)?
Does it have automatic tool setting, tool compensation, and breakpoint continuous cutting functions?
Does it support four-axis linkage (if bevel cutting or 3D engraving is required)?

(4) Degree of automation
Automatic loading and unloading: Is it equipped with a conveyor belt or a robotic arm to reduce manual intervention?
Automatic tool change: If milling, drilling and other multi-process processing are required, is the tool magazine optional?
Laser/camera positioning to ensure cutting accuracy.
Broken knife detection and anti-collision system to reduce loss.

3. Key accessories and consumables
Saw blade/tool:
Diamond saw blade (dry cutting/wet cutting), different stone materials need to match different tool heads.
Does it support multi-tool head switching (such as cutting + milling)?
Cooling system: water cooling (reduce dust, extend saw blade life) or dry cutting (suitable for some ceramic plates)?
Dust removal system: industrial vacuum cleaner or water curtain dust removal? Does it meet environmental protection requirements?

4. Brand and after-sales service
Well-known brands (domestic/international):
Domestic: Hualong, etc.
International: Breton (Italy), Pedrini (Italy), GMM (Italy).
After-sales support:
Is free installation training provided?
How long is the warranty period? Are key components (such as spindles and CNC systems) warrantied separately?
Are there any local service outlets? How long is the response time?

5. Energy consumption and maintenance costs:
Electricity costs, tool replacement frequency, lubrication and maintenance costs.
Return on investment (ROI):
Calculate the average daily production capacity, compare labor costs, and estimate the payback period.

6. Field investigation and testing
Factory test machine:
Observe the machine's running stability, cutting accuracy, and noise level.
Test the cutting effect of different materials (such as granite and marble).

Customer cases:
Ask the manufacturer if there are successful cases with similar processing needs.
