Technical FAQ & Operational Guide
What is the advantage of the square body design for this spindle?
The square body profile provides a flat, stable mounting surface. This ensures a more rigid connection to the machine headstock than round spindles, significantly reducing vibration during high-speed precision tasks like PCB routing or jewelry engraving.
Can I run this spindle on both single-phase and three-phase power?
Yes, this motor is designed with dual-voltage support. When paired with the appropriate Variable Frequency Drive (VFD), it can be configured to run on 220V or 380V setups, making it highly adaptable to different workshop power standards.
Is the cooling sufficient for continuous operation?
Absolutely. This model features an integrated high-efficiency air cooling system. It is designed to maintain optimal operating temperatures during continuous light-duty machining cycles without the need for external water pumps or chillers.
