Where fixed-speed grinders force you to compromise between material types, the LM30-VE's frequency inverter-driven motor gives you four discrete speed settings — 150 to 527 RPM — so you can match machine performance to the material and finish you're working toward.\u003c\/p\u003e\n\u003cp\u003eThe 300 mm plate accepts prismatic, Frankfurt, and comma tooling systems, making it compatible with the abrasive systems already in your shop. An eccentric wheel axis allows machine level adjustment on uneven surfaces, and pivoting wheels with easy-grip handles keep it maneuverable across large floor areas. Available in 3 HP and 4 HP single-phase configurations to match your power requirements.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features \u0026amp; Benefits\u003c\/h2\u003e\n\u003ch3\u003eFrequency Inverter-Driven Variable Speed Motor\u003c\/h3\u003e\n\u003cp\u003eThe motor is driven by a frequency inverter rather than a simple speed switch — this improves torque control, efficiency, and machine output consistency across all four speed settings.
