Beside milling metal, the machining of stone makes the highest demands in the CNC manufacturing. When it comes to deep machining of granite, marble and slate, it turns out if the machine construction is stable enough in all axes to avoid the bending of the components during the machining process. An unstable built CNC router cannot process the milling paths precisely and produces inaccurate results. You can visualise this by imagining a machine which is supposed to mill a straight line into stone, but due to the bending of the Z-axis, the milling cutter shifts left and right which makes it impossible for the machine to create a straight line.
Trying to engrave fonts as a 3D relief in solid stone, many homemade CNC routers fail because of low-quality components or non-professional mounting. How to design a stable machine with steel components and a high-frequency spindle which is sturdy enough to mill stone accurately in the low-price segment? Asking this question is crucial before buying a CNC machine. A standard milling motor is sufficient for machining wood, brass or plastic. But milling solid stone like granite you need the performance of a high-frequency spindle for getting good results. In the following pictures you the quality of stone engravings made by the RaptorX milling machine and an HF-spindle:

Before purchasing a machine, you should know that milling marble or granite requires a much more robust CNC router and a high-frequency spindle than milling Softwood or plastic.
Of course, you need to spend more money on such a machine due to the high-quality component used for building the machine.
The following tips will help you to buy an appropriate CNC router for machining stone:
You should better expect to spend more money. Usually, cheap CNC routers cannot mill resistant stone in the deep.

Jacob from United States
I am a beginner at CNC, I’ve never used a CNC machine before and with in a day I was carving. An awesome machine for a beginner to learn as hobbyists. I used the manual and the help video. One hour to assemble and test, very friendly and easy to use. It’s a good buy for the money. I would definitely recommend this machine to someone getting into CNCs.
Weinstein from France
I've been using CNC plasma SYP2060-300A and I am very impressed with this unit.
This unit is of higher quality, made in China. Five stars all the way!
Fiber Laser Marking Machine from Robert Evans 🇮🇪 Ireland
We bought the SYJF50W fiber laser marking machine for stainless steel and aluminum parts. The marking is sharp, permanent, and very fast. After several months of production, the machine continues to perform perfectly.”
ATC Wood CNC Router from Andrew Collins 🇳🇿 New Zealand
The SYM2040 automatic tool changer saves us a significant amount of production time. Tool changes are fast and accurate, and the machine performs complex woodworking jobs without any problems. Excellent machine and excellent service.
Stone CNC Router from Daniel Murphy🇦🇺 Australia
Our company produces granite and marble countertops. This SYS1530-R stone CNC router delivers precise carving and stable performance even during long working hours. The heavy-duty structure makes a noticeable difference compared to our previous machine.”
Plasma Cutting Machine from James Wilson 🇨🇦 Canada
The SYP2060 plasma cutting machine exceeded our expectations. It cuts mild steel quickly with smooth edges and very little slag. The controller is easy to learn, and the machine has been reliable since day one. Great value for money.”
CO₂ Laser Cutting & Engraving Machine from Michael Carter🇬🇧 United Kingdom
CO₂ Laser Cutting & Engraving MachineWe use the SYJ2030 CO₂ laser machine mainly for acrylic and MDF products. The engraving quality is clean, and the cutting edges require almost no finishing. SENYO provided complete operation videos and answered every question promptly.
Wood CNC Router Machine from David Thompson 🇺🇸 United States
We purchased the SYM1325ATC With Cutting Saw Wood CNC Router for cabinet production six months ago. The machine has been running every day with excellent stability. The cutting accuracy and edge quality are impressive, and the installation guidance from the SENYO team was very professional. We are very satisfied with our investment.
