What Are the Core Differences Between Direct Connected and Belt Type Spindles?

· Operational Mechanisms

The direct connected spindle has a motor shaft connected directly to the spindle shaft.

This setup ensures minimal vibration. In a belt type spindle power transmission is achieved using a belt drive which is based on pulleys and belts.

Models with direct connection provide high precision with fewer moving parts. Belt type is a versatile option that comes with different pulley ratios. Both are suitable for specific applications in machining.

· Speed Control
