How to Cut Stone Countertops with CNC Bridge Saw

Achieve flawless results with granite and marble countertop cutting using 4+1 and 5 axis CNC bridge saws.

The kitchen countertop is the heart of any home renovation project. Whether you are working with granite, marble, or quartz, achieving clean, precise cuts is essential for high-end results. Traditional manual cutting methods often struggle to meet modern design demands, leading to wasted materials and uneven edges.

This is where CNC bridge saws come in—combining advanced automation with precision cutting to deliver professional-quality countertops every time.

Step-by-Step Process for Cutting Stone Countertops

Measurement & CAD Design

Measure cabinet dimensions and any appliance cutouts.
Design the countertop using CAD software (such as AutoCAD or Alphacam).
Include allowances for overhangs and edge profiles.

Tip: Always double-check measurements—Measure Twice, Cut Once.

Material Selection & Preparation

Choose high-quality stone slabs free of cracks or voids.
Inspect the slab for color consistency and structural integrity.
Load the slab carefully onto the machine table using a vacuum lifter or crane.

CNC Bridge Saw Setup

Calibrate the machine (blade speed, feed rate, depth of cut).
Upload your CAD design to the CNC control system.
Verify that the blade path matches the programmed layout.

Rough Cutting

Start with larger cuts to separate sections of the countertop.
Use the machine’s laser guide or camera positioning system for alignment.

Precision Cutting & Edge Profiling

Perform detailed cuts for sinks, faucets, and stove openings.
Shape the edge profiles—bullnose, bevel, ogee, or custom styles.

Pro Tip: Midecnc machines allow you to switch seamlessly between cutting and milling with 4+1 axis control.

Polishing & Finishing

Use diamond polishing pads to refine the surface.
Seal the countertop to protect against moisture and staining.
