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.The 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.Key Features & BenefitsFrequency Inverter-Driven Variable Speed MotorThe 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. Better torque at low RPM means more effective grinding on hard stone without stalling.Four Speed Settings for Material Versatility150, 351, 439, and 527 RPM — slow speeds for aggressive grinding on hard granite and concrete, higher speeds for polishing and finishing on marble and terrazzo. One machine covers the full workflow.Multi-System Abrasive Plate CompatibilityCompatible with prismatic, Frankfurt, and comma plate systems. Works with the tooling you already own — no proprietary abrasive lock-in.Eccentric Wheel Axis Level AdjustmentCompensates for uneven floor surfaces without shimming or manual adjustment — keeps the plate flat and the grind consistent across irregular substrates.Compact Maneuverable DesignPivoting wheels and easy-grip handles make it practical to work across large floor areas without fatigue. Aluminum water tank with epoxy powder coating keeps weight down and corrosion resistance up.Single-Phase Power — No 3-Phase RequiredRuns on standard 230V single-phase supply — no special electrical infrastructure needed. Available in 3 HP and 4 HP to match your site's power capacity.Technical Specifications Specification Detail Motor Power 2.2 kW (3 HP) or 3 kW (4 HP) Voltage 230V, single-phase, 50/60 Hz Drive System Frequency inverter Speed 1 150 RPM Speed 2 351 RPM Speed 3 439 RPM Speed 4 527 RPM Plate Diameter 300 mm (11.8") Plate Compatibility Prismatic, Frankfurt, Comma Water Tank Aluminum, epoxy powder coated SKU PALM30VEF02 Brand Achilli Available Configurations LM30-VE – 1 Phase (230V, 3 HP) – Frankfurt Plate LM30-VE – 1 Phase (230V, 4 HP) – Frankfurt Plate Optional Accessories Planetary Head (300 mm / 11.8") — improved performance on granite and hard stone Bush-Hammering Plate — surface texturing in different grits Single Head Driving Plate (430 mm / 17") — for single-head tooling applications Extra Weight — increases grinding pressure for more aggressive material removal Compatible Materials Marble Granite Terrazzo Concrete Natural stone floors Common Applications Floor grinding and surface preparation on stone and concrete Marble and terrazzo polishing and restoration Granite floor finishing Concrete surface grinding before coating or sealing Bush-hammering and surface texturing (with optional plate) Ideal For Stone restoration contractors working on marble and terrazzo floors Concrete grinding and surface prep professionals Fabrication shops needing a versatile single-phase floor grinder Operations requiring Frankfurt or prismatic tooling compatibility Show more
