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!
SYM1530ATC-A2 from
Thank you Aillen, You are really good person for advice model and service. My furniture work doing very good, thanks
1530 CNC Plasma from Australia
This CNC plasma cuts very easy Very good machine .
But I also recommend purchasing the nozzles and the tips of the torch consumables oarts they wear out quickly and for a good operation they must be in good condition.
Laser welding machine Franklin White from
These are some great information that you have shared herechoosing the right laser welding machine.I really loved it and thank you very much for sharing this with us. You have a great visualization and you have really presented this content in a really good manner.
Fiber Laser 3000W from UK
Thanks for SYJF1530-3000W , The machine runs fast and the cutting effect is good. Fiber laser 1530 meet our job requirements. Thank you on behalf of my business!
5 axis cnc router machine works very good from UK
We bought An 5 axis cnc router . 5axis CNC routers are popular amongst universities to produce 2D and 3D objects from wood, plastics, foam and many more materials.
Universities and schools across the world have produced many prototypes using their CNC machines. CNC routers are popular in architecture,
woodworking, physics and engineering, for projects and research and development.
CNC Router ATC tool changer 1325 from Bangladesh
We bought ATC Tool changer SYM1325-ATC 2018.9 , ATC tool changer for my company
It main working for furniture works , Every day use it work 15 hours , and it really work nice . The sales manager is very nice person
I really love that machine . High recommand !
Maldonado from Mexico
IPG 3000W 3015 Fiber metal laser cutter we have ever purchased.
For 10 hours daily working, it still keeps the high precision and the high working speed. I really love it.
Francisco from Portugal
A máquina CNC funciona muito bem.
A fresadora CNC 1325 é uma unidade bem feita e não encontrei problemas com a qualidade de construção ou operação.
