Hindi A Practical Guide for Fabricators
Kitchen countertops made of marble or granite are prized for their durability and aesthetics. But how are they precisely cut and finished? That’s where CNC bridge saws come in. This article guides you through the step-by-step process of fabricating kitchen countertops using CNC bridge saw machines, especially with granite, marble, and quartz.
Why Use CNC Bridge Saws for Countertops?
CNC bridge saws combine automation, precision, and speed, making them ideal for custom countertop fabrication. Whether you’re cutting slabs to size, making cutouts for sinks, or polishing edges, a CNC bridge saw ensures:
- Clean, accurate cuts
- Reduced material waste
- Compatibility with CAD designs
- Consistent quality across batches
Materials Suitable for CNC Bridge Saw Cutting
CNC bridge saws from Midecnc are compatible with a wide range of countertop materials, including
- Marble: Ideal for classic kitchen designs
- Granite: Known for its hardness and durability
- Quartz: Engineered stone that combines performance and aesthetics
- Sintered Stone / Porcelain: New-generation materials with high resistance
Step-by-Step: How to Make a Kitchen Countertop with a CNC Bridge Saw
Step 1: Slab Selection and Layout Planning
Choose your preferred material slab. Use a camera system or layout software to plan cutting lines and avoid flaws or veins.
Step 2: Load the Slab onto the CNC Machine
Use a tilting worktable (e.g., 85° hydraulic tilt) to safely load heavy stone slabs.
Step 3: CAD Design and Programming
Design your countertop using CAD software. Upload the cutting path to the CNC system using CAM software for toolpath generation.
Step 4: Execute Precision Cutting
Start automatic cutting via the control panel. Features like infrared alignment, 0–360° blade rotation, and camera-aided positioning help maximize accuracy.
Step 5: Cutouts and Finishing
Create cutouts for sinks, faucets, and cooktops. Use a CNC router or manual tools for edge profiling and polishing.

Common Questions About CNC Bridge Saws for Countertops
Q1: Can one machine cut both marble and granite?
Yes, as long as the machine uses a diamond blade and offers variable cutting speed.
Q2: Do I need separate machines for polishing and cutting?
Not necessarily. Some CNC bridge saws can handle rough edge polishing, but for fine polishing, a dedicated edge polishing machine is better.
Q3: What safety measures should I follow?
Always wear PPE, use proper slab handling equipment, and ensure the CNC system is grounded and maintained.
