Prices for 3-axis CNC devices range from $25,000 to $50,000 while 5-axis go from $80,000 to over $500,000. The costs vary depending on whether they are used for entry-level or production-level work.

3-axis milling machines are limited in angle variation and can't achieve the complex undercuts or intricate angles possible with 5- or 6-axis machines, which limits their effectiveness in carving more complex stone designs.

In contrast to conventional 3-axis CNC machines that operate linearly along the X, Y, and Z axes, the 5-axis CNC machine introduces two additional rotational axes, typically labeled as A and B. This heightened flexibility proves especially advantageous in industries where precision and complexity play pivotal roles.
