Buyers often compare machines by maximum spindle speed, but the number that matters most for heavy milling is torque at the cutting zone.
Match Drive to Material
Steel, cast iron, and hardened alloys demand sustained low-speed torque to maintain chip load without stalling. Aluminium and composites benefit more from high spindle speed and feed rate. A direct-drive spindle can deliver both, while geared spindles excel at extreme torque.
Junnuo publishes full spindle torque curves in every quotation, so your engineering team can verify performance against the specific materials you machine before signing.
