Choosing the Perfect ATC Spindle Motor for CNC Machining

The higher the power of the spindle motor, the better the processing effect and the higher the production efficiency

Have you heard this before purchasing a CNC Router? CNC Spindles wants to debunk this myth: the selection of spindle motor power should meet your specific processing needs. Depending on the material, higher power does not always equate to better results and can unnecessarily increase costs. Follow CNC Spindles to learn how to choose the right spindle motor power.

As machining technology advances, so do the requirements for spindle finishing and efficiency. The development of automatic tool change (ATC) technology has revolutionized machining by enabling quick and efficient tool swaps. This has become increasingly important in the face of rising labor costs, making high-speed ATC devices essential for modern machining centers. Here’s how to choose the best ATC spindle motor for your needs.

Pursuing Processing Efficiency

For soft materials like PVC, acrylic, and MDF, a spindle power between 1.5kW and 3.0kW is ideal. This range balances engraving effect and cost savings.

Stone Engraving Machine

Stone processing requires higher power due to the material’s hardness. Typically, a spindle power between 4.5kW and 7.5kW is needed, with 5.5kW water-cooled spindle motors being common.

Tombstone Engraving Machine

Choose spindle power based on stone hardness. Generally, 3.0kW to 4.5kW meets processing requirements and ensures high-quality results.

Jade Carving Machine

For small tables and materials like jade, smaller spindle motors with 2.2kW to 3.0kW power are adequate. High power is unnecessary due to the smaller scale.

Conclusion

The power of an engraving machine spindle should match the specific processing needs rather than opting for higher power indiscriminately. Higher cost performance is more beneficial. CNC Spindles recommends selecting spindle power based on material hardness, processing method, and table size. This approach avoids waste from excessive power selection and ensures the spindle meets processing requirements.
