Frequently Asked Questions

Can CNC machines cut stone?

Yes — modern CNC machines are specifically designed to cut stone accurately and safely. With diamond tooling and rigid motion systems, a CNC machine for stone cutting can shape granite, marble, slate, quartz, and limestone while maintaining consistent depth and edge quality across long production runs.

What tool can cut stones?

Stone is cut using diamond-coated tools mounted on CNC routers or stone machining centers. These include diamond end mills, engraving bits, and core drills that are purpose-built to withstand stone’s hardness while delivering smooth finishes and controlled material removal.

How thick can a CNC cut into stone?

Most professional stone CNC machines can cut 1–6 inches of stone depending on spindle power, tooling, and machine rigidity. Industrial granite CNC machines can exceed this range when performing deep pocketing, profiling, or multi-pass cutting operations.

What is a CNC router for stone used for?

A CNC router for stone is used for engraving text, carving relief artwork, cutting profiles, machining inlays, and producing architectural stone components with repeatable digital accuracy.

Can CNC machines engrave stone?

Yes — a CNC machine for stone engraving can etch fine lettering, logos, portraits, and ornamental patterns directly into granite, marble, slate, and other natural stones using diamond engraving tools.

What is a 3D stone carving machine?

A 3D stone carving machine is a specialized CNC platform designed for multi-axis relief carving, sculptural detailing, and dimensional surface machining, allowing complex textures and contours to be produced automatically from CAD models.

Is water or coolant required for stone CNC machining?

Yes — water cooling and dust suppression are essential when machining stone. Coolant systems extend tool life, reduce micro-fracturing, and keep airborne silica dust safely controlled.

Can CNC machines carve granite?

Absolutely — granite CNC machines are built specifically to handle granite’s hardness and density, making them ideal for monuments, countertops, architectural features, and engraved stone signage.
