Direct-Drive Torque Motors Reach Standard Product Tiers
Direct-drive torque motor rotary tables, once reserved for premium aerospace applications, are reaching standard product tiers as servo component costs fall and five-axis machining adoption spreads across mid-size job shops. Eliminating the gear train removes backlash entirely and improves dynamic stiffness during high-speed contouring, a capability increasingly required for aerospace structural components and complex mold cavities. Major rotary table makers including Nikken Kosakusho and TSUDAKOMA have expanded direct-drive production capacity over the past two years, and distributors report direct-drive platforms now specified on roughly one in four new five-axis machining center orders.
Market Impact: Adds 6,200 new five-axis installati
